Miniserv shutting down on a CentOS running on OpenVZ

Notes on VPSLink and Virtualmin

I’m not sure of the Etiquette but I included some logs to see if a problem can be spotted in them. They are kind of long so if this is bad, let me know and I won’t do it again.

Question Follows the Lead-In

I installed and tested Virtualmin Pro on my test box to bring myself up to speed before using it on http://www.vpslink.com which is based on the http://openvz.org/ project.

On my test box it seems to work perfect.

Without reading my long lead in diatribe… In a nutshell (in case there is a quick answer) Are there issues with OpenVZ/Virtualmin setup?

I’m beginning to wonder if oddities of a VPS instead of a physical server is causing some issues. Kind of like Virtualmin is parsing the VPS for something and getting back something it doesn’t like? Not sure.

Or maybe they reboot the physical machine the VPS is running on and this cures the issues for a while?

Sometimes everything seems to be going very well and then it will start to malfunction so I can’t tell if it’s the VPS or Virtualmin or a combo of both interacting?

I also suspect a filewall interaction which I talk about later.

The problem I’m haveing is, the miniserver is shutting down periodically and needs to be restarted via the shell.

[[root@sitename ~]]# service webmin restart
Stopping Webmin server in /usr/libexec/webmin
/etc/webmin/stop: line 4: kill: (32381) - No such process

[[root@sitename ~]]# service webmin start … to get the miniserver going again.

Now that it’s started you can issue a restart and a list of modules getting pre-loaded scroll by.

OK… back to the leadin to the problem.

The VPSLink CentOS installation is very lite. So lite that you have to begin by installing yum and it’s dependencies as well as up2date so that virtualmin pro can begin to install.

Also I found that the install.sh script points to up2date in the /usr/bin dir but on the lite centos, yum install up2date places up2date in the /usr/sbin as well as the /usr/bin and for some reason the one in /usr/bin is not found by install.sh

No problems here… I edited the install.sh to point to the /usr/sbin/up2date and it worked perfectly.

Virtualmin pro is now intalled on vpslink plan #4 which gives you 3 ip addresses and resides on a scsi drive.

Virtualmin didn’t detect the virtual network interface so I input that and that works fine now.

Everything worked now accept quotas because of how the VPS is setup or something. I got this working by following sleddogs instructions by using Webmin and System/Disk and Network Filesystems/module config and telling it to use mtab instead of fstab as noted in his post here:
http://forums.vpslink.com/showpost.php?p=1699&postcount=9

However the config isn’t under hardware as his post suggests, it’s under system.

Quotas and everything else works great now Except…

NOW FOR THE QUESTION.

Webmin is needs to be restarted periodically or more precicely, if it shuts down, you have to issue a service webmin start because if the webmin service is not running so the restart doesn’t work until you start it.

Since I received zero errors during the install and the install seemed to complete ok, and then later found that the miniserver keeps shutting down and needing to be restarted I thought there may be a conflict with VPS’s.

I move around pretty quick in the Virtualmin interface and usually have 3 tabs open in firefox to display the filemanager and 2 other sectons of the virtualmin interface.

I thought this may be causing a problem but this is the way I have worked in webmin for years so I figured it’s a symptom of the VPS and Virtualmins interactions.

After looking at the logs I found that it may have something to do with Authen::PAM so I installed that and while I was at it I installed Authen::Libwrap so now All of the Perl modules recommended by Webmin are installed.

The error I saw concerning PAM is now gone but the miniserver is still shutting down so I guess it’s not PAM.

Anyway I have until the end of this month to get this working on the VPS before the half price deal goes away.

If I can get this to be reliable on the VPS, I’ll buy a year from them.

I also tried to run install.sh again to see what would happen and it did pull a couple of things down but still no luck.

Also I tried the rpm -e virtualmin-release and running install.sh again and still no party.

I’ve tried total reinstalls several times to see if I can figure out when the miniserver starts shutting down or if it’s one of those problems that corrects itself because the planets are in the right place during the install :-).

I noticed during one of the reinstalls that I hadn’t initialized the firewall and there was no problems. I then used the webin module to initialize the firewall and opened the webmin and usermin ports and applied the config and within a short time the problems started again so I’m wondering if the firewall could be causing an issue?

Now after all this writing you will probably tell me about a simple switch to cure my problems :slight_smile:

Thanks
John

Now I wonder if it could be memory related. Maybe I need t go ahead and get the #5 plan with 1024 ram[p][font face="Courier New, Courier, mono"]vpsstat[/p]Resource Current Recent Max Barrier Limit Failures

Hi John,

Looks kinda like memory might be an issue.

You can probably shutdown some unnecessary services, depending on your needs, which might free up enough memory.

FTP is unnecessary and dangerous, if you and your users can be convinced not to use it, and to use SSH/SCP and FTP over SSH instead. So, you can turn off ProFTPd with (the following two commands will shutdown and disable on boot whatever service you name):

service proftpd stop
chkconfig --level 345 proftpd off

You can shutdown and disable whichever database server(s) you don’t use, whether it’s PostgreSQL or MySQL. You’ll have to tell Virtualmin that you don’t use it, too, of course. If the software you’re using supports SQLite, you could disable both of the big databases and just use SQLite, which is much smaller. Virtualmin doesn’t rely on any database to be running, as long as you tell it you don’t want to provide databases for your users.

gpm can be disabled. You probably don’t have console access anyway. gpm is the console mouse service. Oh, actually, I see that it’s failing…so it’s not taking memory anyway. But removing it will clean up your log some.

If you don’t use telnet (please tell me you don’t use telnet!) you can probably shutdown xinetd. It can be used to start other services, but it probably isn’t, so kill it and get back that little bit of memory.

The rpc and nfs stuff is possibly not needed (but check to be sure none of your directories are being mounted via NFS first). This would include portmap, nfslock, nfs, netfs, rpc*. But I don’t see it being started, so this might already be disabled.

That’s at least a start. There’s probably some other stuff you can kill to free up some memory, if budget prevents you from getting more memory.

Webmin and Usermin aren’t huge, but they aren’t tiny either. My parent processes are running at about 10MB each (with quite a bit of that being shared libs that both are using). Though, the child processes, spawned for each new user that is logged in at any given time, can grow quite a bit bigger when used for things that require caching and/or indexing, like reading email. I’ve seen them grow to 50 MB or so, I think. Not much to be done about that, except maybe not using webmail (of any sort–any webmail that provides reasonable search, sort, and speed, is going to have to do caching in a pretty similar way)…or making sure mailboxes are never very big.

Thanks so much for the quick reply Joe.

I went ahead and upgraded the VLink #5 to get the higher mem/disk space and 2 more IP’s

I disabled ProFTPd. I don’t use it and wouldn’t have allowed any users to use it either.

No :slight_smile: I don’t use telnet.

I’m just setting up a small VPS to consolidate some clients and they really won’t be purposly given the ability to mess things up and 99.9% of them would have to call me to find out how to setup their ftp client to use ssh if they ever cared to do that.

They mainly use the admin interface of interchange or OSCommerce to add products and manage customers.

I have one girl I trained to winscp images to a directory so she could make banners.

I’m really happy you have implemented an easy way to use pop3s via dovecot so I can set my clients up with outlook and still keep their passwords encrypted.

I disabled plain text logins in dovecot but I need to make sure there is no other way to do a plain text login.

Before dovecot I found a great pop3s howto and I disabled pop3 completely so all that could be used was pop3s.

Anyway, memory should be less of an issue now that I switched to the better VPS plan.

I noticed there a lot of duplicate processes. Is this fairly normal?

This is a pretty much stock minimal server with only Virtualmin installed. Oh and Interchange.

As I mentioned, it’s so minimal I even had to start by installing yum and up2date just to get going :slight_smile:

I have 4 domains installed at the moment only 2 of which are live and none really active either at the moment

Thanks again,
John

I noticed there a lot of duplicate processes. Is this fairly normal?

Yes, all of the servers start a parent process, plus some number of children (or they spawn children on an as-needed basis). All of them are configurable, and you may see a small (probably tiny) memory usage benefit from cutting back on the number of idle Apache processes. The mail processes are spawned on an as-needed basis. None of them take up very much memory, as they use a lot of shared libraries, and so the actual usage is probably half or less of what it appears.

Ahh,

Sorry. I think this was asked and answered. I remember you mentioning something about this to someone else as I was browsing your forums.

And so far so good on the upgraded VPS with 1024 megs of memory. :slight_smile: No quirks at all. I hope it was as easy as a memory issue.
