Virtualmin install.sh support for CentOS 8

News

I installed Virtualmin on Centos8.
Some problems occurred but I found some workarounds on this and other websites.

After a clean install of Centos8, log in with ssh:

Perl problem
First install perl. then install virtualmin
dnf install perl -y
wget http://software.virtualmin.com/gpl/scripts/install.sh
sudo /bin/sh install.sh =>Y

Postfix problem:
Add the following text in Postfix
Webmin > Servers > Postfix Mail Server > Virtual Domains >Domain mapping lookup tables = hash:/etc/postfix/virtual

MYSQL problem with root password
service mysqld stop
mysqld_safe --skip-grant-tables &
Mysql
At the mysql> prompt, reset the password. To do this, type the following command, replacing new-password with the new root password:
UPDATE mysql.user SET Password=PASSWORD(‘NEW PASSWORD’) WHERE User=‘root’;

At the mysql> prompt, type the following commands:
FLUSH PRIVILEGES;
exit;

Stop the MySQL server using the following command. You will be prompted to enter the new MySQL root password before the MySQL server shuts down:
mysqladmin -u root -p shutdown

For CentOS and Fedora, type:
service mysqld start

Webmin/Virtualmin is now fully working :slight_smile:

However, I’ don’t succeed in adding letsencrypt certificates.
I use the providers DNS so need website verification
I was able to add a letsencrypt certificate in Webmin for the main server.
The virtual servers always returns errors (Forbidden). I asked to get a certificate at installation of the virtual server.
After that failed, I tried to add a letsencrypt certificate with Server configuration/ssl configuration/letsencrypt. I flushed all redirections and made sure that the website was accessible. I even tried to set permissions on 777=> No success
Any idea’s how to solve?
