SSL.conf overriding SSL certificate for vhost in httpd.conf

The default self SSL certificate is overriding the letsencrypt certificate I have generated on my virtual host.

I am using for virtualmin and for

However when I visit i get a certificate error and the self signed certificate that was generated when virtualmin was first installed.

The only way I have found of fixing this is to change two lines in ssl.conf from:
SSLCertificateFile /etc/pki/tls/certs/localhost.crt
SSLCertificateKeyFile /etc/pki/tls/private/localhost.key


SSLCertificateFile /home/
SSLCertificateKeyFile /home/

However this is going to cause problems if I need to add a second virtual host with an SSL certificate. Why is Apache ignoring the httpd.conf lines pointing to

You haven’t given us any information about the OS version that you are using. Which is another way of saying you don’t think the exact layout of Apache config files matters in this case. Maybe it actually does.

Is Apache ignoring only the SSL certificate lines for, or is it completely ignoring the entire section for Depending on the answer you will be one step closer to identifying the cause of the problem.

Sorry its Centos 7 x86_64. Running on a Esxi.

It seems the other part of the vhost config is OK as the virtual host works without problem on the non https side.

Since http and https require different sections, the fact that the one for http works doesn’t mean that Apache isn’t ignoring the one for https.

In a CentOS 7 environment, the defaults for https are set in ssl.conf, but Virtualmin adds https sections into httpd.conf. So you have to consider the interaction of both files. Whereas for http, everything is in httpd.conf. So it’s quite possible for https to work while https doesn’t. One possible source of problems is if you edit httpd.conf trying to fix your https sites, not realizing that some lines you added into httpd.conf conflict with lines present in ssl.conf.

Here are the two config files, thank you for the assistance!

When we also provide SSL we have to listen to the

the HTTPS port in addition.

SSL Global Context

All SSL configuration in this context applies both to

the main server and all SSL-enabled virtual hosts.

Pass Phrase Dialog:

Configure the pass phrase gathering process.

The filtering dialog program (`builtin’ is a internal

terminal dialog) has to provide the pass phrase on stdout.

SSLPassPhraseDialog exec:/usr/libexec/httpd-ssl-pass-dialog

Inter-Process Session Cache:

Configure the SSL Session Cache: First the mechanism

to use and second the expiring timeout (in seconds).

SSLSessionCache shmcb:/run/httpd/sslcache(512000)
SSLSessionCacheTimeout 300

Pseudo Random Number Generator (PRNG):

Configure one or more sources to seed the PRNG of the

SSL library. The seed data should be of good random quality.

WARNING! On some platforms /dev/random blocks if not enough entropy

is available. This means you then cannot use the /dev/random device

because it would lead to very long connection times (as long as

it requires to make more entropy available). But usually those

platforms additionally provide a /dev/urandom device which doesn’t

block. So, if available, use this one instead. Read the mod_ssl User

Manual for more details.

SSLRandomSeed startup file:/dev/urandom 256
SSLRandomSeed connect builtin
#SSLRandomSeed startup file:/dev/random 512
#SSLRandomSeed connect file:/dev/random 512
#SSLRandomSeed connect file:/dev/urandom 512

Use “SSLCryptoDevice” to enable any supported hardware

accelerators. Use “openssl engine -v” to list supported

engine names. NOTE: If you enable an accelerator and the

server does not start, consult the error logs and ensure

your accelerator is functioning properly.

SSLCryptoDevice builtin
#SSLCryptoDevice ubsec

SSL Virtual Host Context


General setup for the virtual host, inherited from global configuration

#DocumentRoot “/var/www/html”

Use separate log files for the SSL virtual host; note that LogLevel

is not inherited from httpd.conf.

ErrorLog logs/ssl_error_log
TransferLog logs/ssl_access_log
LogLevel warn

SSL Engine Switch:

Enable/Disable SSL for this virtual host.

SSLEngine on

SSL Protocol support:

List the enable protocol levels with which clients will be able to

connect. Disable SSLv2 access by default:

SSLProtocol +TLSv1 +TLSv1.1 +TLSv1.2

SSL Cipher Suite:

List the ciphers that the client is permitted to negotiate.

See the mod_ssl documentation for a complete list.


Speed-optimized SSL Cipher configuration:

If speed is your main concern (on busy HTTPS servers e.g.),

you might want to force clients to specific, performance

optimized ciphers. In this case, prepend those ciphers

to the SSLCipherSuite list, and enable SSLHonorCipherOrder.

Caveat: by giving precedence to RC4-SHA and AES128-SHA

(as in the example below), most connections will no longer

have perfect forward secrecy - if the server’s key is

compromised, captures of past or future traffic must be

considered compromised, too.

#SSLHonorCipherOrder on

Server Certificate:

Point SSLCertificateFile at a PEM encoded certificate. If

the certificate is encrypted, then you will be prompted for a

pass phrase. Note that a kill -HUP will prompt again. A new

certificate can be generated using the genkey(1) command.

#SSLCertificateFile /etc/pki/tls/certs/localhost.crt
SSLCertificateFile /home/

Server Private Key:

If the key is not combined with the certificate, use this

directive to point at the key file. Keep in mind that if

you’ve both a RSA and a DSA private key you can configure

both in parallel (to also allow the use of DSA ciphers, etc.)

#SSLCertificateKeyFile /etc/pki/tls/private/localhost.key
SSLCertificateKeyFile /home/

Server Certificate Chain:

Point SSLCertificateChainFile at a file containing the

concatenation of PEM encoded CA certificates which form the

certificate chain for the server certificate. Alternatively

the referenced file can be the same as SSLCertificateFile

when the CA certificates are directly appended to the server

certificate for convinience.

#SSLCertificateChainFile /etc/pki/tls/certs/server-chain.crt

Certificate Authority (CA):

Set the CA certificate verification path where to find CA

certificates for client authentication or alternatively one

huge file containing all of them (file must be PEM encoded)

#SSLCACertificateFile /etc/pki/tls/certs/ca-bundle.crt

Client Authentication (Type):

Client certificate verification type and depth. Types are

none, optional, require and optional_no_ca. Depth is a

number which specifies how deeply to verify the certificate

issuer chain before deciding the certificate is not valid.

#SSLVerifyClient require
#SSLVerifyDepth 10

Access Control:

With SSLRequire you can do per-directory access control based

on arbitrary complex boolean expressions containing server

variable checks and other lookup directives. The syntax is a

mixture between C and Perl. See the mod_ssl documentation

for more details.

#SSLRequire ( %{SSL_CIPHER} !~ m/^(EXP|NULL)/ \

and %{SSL_CLIENT_S_DN_O} eq “Snake Oil, Ltd.” \

and %{SSL_CLIENT_S_DN_OU} in {“Staff”, “CA”, “Dev”} \

and %{TIME_WDAY} >= 1 and %{TIME_WDAY} <= 5 \

and %{TIME_HOUR} >= 8 and %{TIME_HOUR} <= 20 ) \

or %{REMOTE_ADDR} =~ m/^192.76.162.[0-9]+$/


SSL Engine Options:

Set various options for the SSL engine.

o FakeBasicAuth:

Translate the client X.509 into a Basic Authorisation. This means that

the standard Auth/DBMAuth methods can be used for access control. The

user name is the `one line’ version of the client’s X.509 certificate.

Note that no password is obtained from the user. Every entry in the user

file needs this password: `xxj31ZMTZzkVA’.

o ExportCertData:

This exports two additional environment variables: SSL_CLIENT_CERT and

SSL_SERVER_CERT. These contain the PEM-encoded certificates of the

server (always existing) and the client (only existing when client

authentication is used). This can be used to import the certificates

into CGI scripts.

o StdEnvVars:

This exports the standard SSL/TLS related `SSL_*’ environment variables.

Per default this exportation is switched off for performance reasons,

because the extraction step is an expensive operation and is usually

useless for serving static content. So one usually enables the

exportation for CGI and SSI requests only.

o StrictRequire:

This denies access when “SSLRequireSSL” or “SSLRequire” applied even

under a “Satisfy any” situation, i.e. when it applies access is denied

and no other module can change it.

o OptRenegotiate:

This enables optimized SSL connection renegotiation handling when SSL

directives are used in per-directory context.

#SSLOptions +FakeBasicAuth +ExportCertData +StrictRequire
<Files ~ “.(cgi|shtml|phtml|php3?)$”>
SSLOptions +StdEnvVars

<Directory “/var/www/cgi-bin”>
SSLOptions +StdEnvVars

SSL Protocol Adjustments:

The safe and default but still SSL/TLS standard compliant shutdown

approach is that mod_ssl sends the close notify alert but doesn’t wait for

the close notify alert from client. When you need a different shutdown

approach you can use one of the following variables:

o ssl-unclean-shutdown:

This forces an unclean shutdown when the connection is closed, i.e. no

SSL close notify alert is send or allowed to received. This violates

the SSL/TLS standard but is needed for some brain-dead browsers. Use

this when you receive I/O errors because of the standard approach where

mod_ssl sends the close notify alert.

o ssl-accurate-shutdown:

This forces an accurate shutdown when the connection is closed, i.e. a

SSL close notify alert is send and mod_ssl waits for the close notify

alert of the client. This is 100% SSL/TLS standard compliant, but in

practice often causes hanging connections with brain-dead browsers. Use

this only for browsers where you know that their SSL implementation

works correctly.

Notice: Most problems of broken clients are also related to the HTTP

keep-alive facility, so you usually additionally want to disable

keep-alive for those clients, too. Use variable “nokeepalive” for this.

Similarly, one has to force some clients to use HTTP/1.0 to workaround

their broken HTTP/1.1 implementation. Use variables “downgrade-1.0” and

“force-response-1.0” for this.

BrowserMatch “MSIE [2-5]”
nokeepalive ssl-unclean-shutdown
downgrade-1.0 force-response-1.0

Per-Server Logging:

The home of a custom SSL log file. Use this when you want a

compact non-error SSL logfile on a virtual host basis.

CustomLog logs/ssl_request_log
“%t %h %{SSL_PROTOCOL}x %{SSL_CIPHER}x “%r” %b”


This is the main Apache HTTP server configuration file. It contains the

configuration directives that give the server its instructions.

See URL: for detailed information.

In particular, see


for a discussion of each configuration directive.

Do NOT simply read the instructions in here without understanding

what they do. They’re here only as hints or reminders. If you are unsure

consult the online docs. You have been warned.

Configuration and logfile names: If the filenames you specify for many

of the server’s control files begin with “/” (or “drive:/” for Win32), the

server will use that explicit path. If the filenames do not begin

with “/”, the value of ServerRoot is prepended – so ‘log/access_log’

with ServerRoot set to ‘/www’ will be interpreted by the

server as ‘/www/log/access_log’, where as ‘/log/access_log’ will be

interpreted as ‘/log/access_log’.

ServerRoot: The top of the directory tree under which the server’s

configuration, error, and log files are kept.

Do not add a slash at the end of the directory path. If you point

ServerRoot at a non-local disk, be sure to specify a local disk on the

Mutex directive, if file-based mutexes are used. If you wish to share the

same ServerRoot for multiple httpd daemons, you will need to change at

least PidFile.

ServerRoot “/etc/httpd”

Listen: Allows you to bind Apache to specific IP addresses and/or

ports, instead of the default. See also the


Change this to Listen on specific IP addresses as shown below to

prevent Apache from glomming onto all bound IP addresses.

Listen 80

Dynamic Shared Object (DSO) Support

To be able to use the functionality of a module which was built as a DSO you

have to place corresponding `LoadModule’ lines at this location so the

directives contained in it are actually available before they are used.

Statically compiled modules (those listed by `httpd -l’) do not need

to be loaded here.


LoadModule foo_module modules/

Include conf.modules.d/*.conf

If you wish httpd to run as a different user or group, you must run

httpd as root initially and it will switch.

User/Group: The name (or #number) of the user/group to run httpd as.

It is usually good practice to create a dedicated user and group for

running httpd, as with most system services.

User apache
Group apache

‘Main’ server configuration

The directives in this section set up the values used by the ‘main’

server, which responds to any requests that aren’t handled by a

definition. These values also provide defaults for

any containers you may define later in the file.

All of these directives may appear inside containers,

in which case these default settings will be overridden for the

virtual host being defined.

ServerAdmin: Your address, where problems with the server should be

e-mailed. This address appears on some server-generated pages, such

as error documents. e.g.

ServerAdmin root@localhost

ServerName gives the name and port that the server uses to identify itself.

This can often be determined automatically, but we recommend you specify

it explicitly to prevent problems during startup.

If your host doesn’t have a registered DNS name, enter its IP address here.


Deny access to the entirety of your server’s filesystem. You must

explicitly permit access to web content directories in other

blocks below.

AllowOverride none Require all denied

Note that from this point forward you must specifically allow

particular features to be enabled - so if something’s not working as

you might expect, make sure that you have specifically enabled it


DocumentRoot: The directory out of which you will serve your

documents. By default, all requests are taken from this directory, but

symbolic links and aliases may be used to point to other locations.

DocumentRoot “/var/www/html”

Relax access to content within /var/www.

<Directory “/var/www”>
AllowOverride None
# Allow open access:
Require all granted

Further relax access to the default document root:

<Directory “/var/www/html”>
# Possible values for the Options directive are “None”, “All”,
# or any combination of:
# Indexes Includes FollowSymLinks SymLinksifOwnerMatch ExecCGI MultiViews
# Note that “MultiViews” must be named explicitly — “Options All”
# doesn’t give it to you.
# The Options directive is both complicated and important. Please see
# for more information.
Options Indexes FollowSymLinks

# AllowOverride controls what directives may be placed in .htaccess files.
# It can be "All", "None", or any combination of the keywords:
#   Options FileInfo AuthConfig Limit
AllowOverride None

# Controls who can get stuff from this server.
Require all granted

DirectoryIndex: sets the file that Apache will serve if a directory

is requested.

DirectoryIndex index.html

The following lines prevent .htaccess and .htpasswd files from being

viewed by Web clients.

<Files “.ht*”>
Require all denied

ErrorLog: The location of the error log file.

If you do not specify an ErrorLog directive within a

container, error messages relating to that virtual host will be

logged here. If you do define an error logfile for a

container, that host’s errors will be logged there and not here.

ErrorLog “logs/error_log”

LogLevel: Control the number of messages logged to the error_log.

Possible values include: debug, info, notice, warn, error, crit,

alert, emerg.

LogLevel warn

# # The following directives define some format nicknames for use with # a CustomLog directive (see below). # LogFormat "%h %l %u %t \"%r\" %>s %b \"%{Referer}i\" \"%{User-Agent}i\"" combined LogFormat "%h %l %u %t \"%r\" %>s %b" common

# # Redirect: Allows you to tell clients about documents that used to # exist in your server's namespace, but do not anymore. The client # will make a new request for the document at its new location. # Example: # Redirect permanent /foo
# Alias: Maps web paths into filesystem paths and is used to
# access content that does not live under the DocumentRoot.
# Example:
# Alias /webpath /full/filesystem/path
# If you include a trailing / on /webpath then the server will
# require it to be present in the URL.  You will also likely
# need to provide a <Directory> section to allow access to
# the filesystem path.

# ScriptAlias: This controls which directories contain server scripts. 
# ScriptAliases are essentially the same as Aliases, except that
# documents in the target directory are treated as applications and
# run by the server when requested rather than as documents sent to the
# client.  The same rules about trailing "/" apply to ScriptAlias
# directives as to Alias.
ScriptAlias /cgi-bin/ "/var/www/cgi-bin/"

“/var/www/cgi-bin” should be changed to whatever your ScriptAliased

CGI directory exists, if you have that configured.

<Directory “/var/www/cgi-bin”>
AllowOverride None
Options None
Require all granted

# # TypesConfig points to the file containing the list of mappings from # filename extension to MIME-type. # TypesConfig /etc/mime.types
# AddType allows you to add to or override the MIME configuration
# file specified in TypesConfig for specific file types.
#AddType application/x-gzip .tgz
# AddEncoding allows you to have certain browsers uncompress
# information on the fly. Note: Not all browsers support this.
#AddEncoding x-compress .Z
#AddEncoding x-gzip .gz .tgz
# If the AddEncoding directives above are commented-out, then you
# probably should define those extensions to indicate media types:
AddType application/x-compress .Z
AddType application/x-gzip .gz .tgz

# AddHandler allows you to map certain file extensions to "handlers":
# actions unrelated to filetype. These can be either built into the server
# or added with the Action directive (see below)
# To use CGI scripts outside of ScriptAliased directories:
# (You will also need to add "ExecCGI" to the "Options" directive.)
#AddHandler cgi-script .cgi

# For type maps (negotiated resources):
#AddHandler type-map var

# Filters allow you to process content before it is sent to the client.
# To parse .shtml files for server-side includes (SSI):
# (You will also need to add "Includes" to the "Options" directive.)
AddType text/html .shtml
AddOutputFilter INCLUDES .shtml

Specify a default charset for all content served; this enables

interpretation of all content as UTF-8 by default. To use the

default browser choice (ISO-8859-1), or to allow the META tags

in HTML content to override this choice, comment out this


AddDefaultCharset UTF-8

# # The mod_mime_magic module allows the server to use various hints from the # contents of the file itself to determine its type. The MIMEMagicFile # directive tells the module where the hint definitions are located. # MIMEMagicFile conf/magic

Customizable error responses come in three flavors:

1) plain text 2) local redirects 3) external redirects

Some examples:

#ErrorDocument 500 “The server made a boo boo.”
#ErrorDocument 404 /missing.html
#ErrorDocument 404 “/cgi-bin/”
#ErrorDocument 402

EnableMMAP and EnableSendfile: On systems that support it,

memory-mapping or the sendfile syscall may be used to deliver

files. This usually improves server performance, but must

be turned off when serving from networked-mounted

filesystems or if support for these functions is otherwise

broken on your system.

Defaults if commented: EnableMMAP On, EnableSendfile Off

#EnableMMAP off
EnableSendfile on

OMG that’s a lot. I would check to make sure the ‘Listen’ directives match the ‘Virtualhost’ directives. Also, I suggest doing all the checks they recommend on this page:

I’m having this same issue… setting up Centos 7 based web server and can’t get any site.tld:443 virtual host to use it’s own cert. Always picks up the cert from the <VirtualHost default *:443> within /etc/httpd/conf.modules.d/00-ssl.conf which is included by httpd.conf.

Some other info - it’s an AWS EC2 instance. The /home and /var/log folders are symlinked to a second EBS volume mounted at /data (/home->/data/home & /var/log->/data/log). I’ve modified all the SELinux labeling to match the default installation folders. SELinux is running in permissive mode so that shouldn’t really matter anyway.

The hostname hase been set correctly (modified the AWS cloud.conf so it doesn’t get overwritten each boot).

Apache version is 2.4.6 running in MDM Event. I currently only have two virtual domains on the machine.
Both http and https content is served without issue but on https I get the invalid cert warning. The certificate is always this …

SSLCertificateFile /etc/pki/tls/certs/localhost.crt

… no matter which domain I’m trying. It’s like SNI isn’t working at all.

Not sure it this is a red herring or not but trying the site with curl produces the following… (this is my test domain that will disappear as soon as I get things working :slight_smile: )

  • Issuer certificate is invalid.
  • Closing connection 0
    curl: (60) Issuer certificate is invalid.
    More details here:

curl performs SSL certificate verification by default, using a “bundle”
of Certificate Authority (CA) public keys (CA certs). If the default
bundle file isn’t adequate, you can specify an alternate file
using the --cacert option.
If this HTTPS server uses a certificate signed by a CA represented in
the bundle, the certificate verification probably failed due to a
problem with the certificate (it might be expired, or the name might
not match the domain name in the URL).
If you’d like to turn off curl’s verification of the certificate, use
the -k (or --insecure) option.

The virtual host config for that domain is …

I read on one forum that disabling the default virtual server in ssl.conf fixed this but then how do I get all the other default ssl config to be used without including it in every <VirtualHost… > config?

I also read that Apache 2.4 needs the cert and chain / CA appended into one file and provided as SSLCertificateFIle but couldn’t confirm this - it would also be a real pain in the &#@ to have to do this manually for each cert renewal.

Any ideas?
I can provide a webmin login if that helps (can’t provide SSH at present as it’s only working with certificates and I haven’t worked out how to autogen new certs for new users)


The version of cURL I’m using is
curl 7.29.0 (x86_64-redhat-linux-gnu) libcurl/7.29.0 NSS/3.19.1 Basic ECC zlib/1.2.7 libidn/1.28 libssh2/1.4.3
Protocols: dict file ftp ftps gopher http https imap imaps ldap ldaps pop3 pop3s rtsp scp sftp smtp smtps telnet tftp
Features: AsynchDNS GSS-Negotiate IDN IPv6 Largefile NTLM NTLM_WB SSL libz

And OpenSSL is
OpenSSL 1.0.1e-fips 11 Feb 2013

So these should allow cURL to use SNI

Hey Craig,

Did you ever get an answer on this? I’m having the same issue, with the default cert overriding my Let’s Encrypt issued cert:

curl -v -L

  • Rebuilt URL to:
  • Trying…
  • Connected to ( port 443 (#0)
  • SSL certificate problem: Invalid certificate chain
  • Curl_http_done: called premature == 1
  • Closing connection 0
    curl: (60) SSL certificate problem: Invalid certificate chain
