If you just want Webmin to be accessible via an URL subdirectory (like /webmin) on an Apache server without going to the trouble of configuring Apache to run the CGI scripts directly, there is a simpler method that can be used.
This is also useful if your system is only accessible on port 80, and you want access to both Webmin and a normal website. The steps to follow are :
Make sure mod_proxy is installed on your Apache webserver.
Add the following directives to the Apache configuration file:
ProxyPass /webmin/ http://localhost:10000/
ProxyPassReverse /webmin/ http://localhost:10000/
<Proxy *>
allow from all
</Proxy>
Add the lines webprefix=/webmin and webprefixnoredir=1 to /etc/webmin/config.
In /etc/webmin/config, add the line referer=apachehost, where apachehost is the hostname from the URL used to access Webmin via Apache.
If the referer line already has some hosts listed, add apachehost to it.
Re-start Apache to apply the configuration.
All requests to /webmin on the Apache server will then be passed through to the Webmin server on localhost port 10000.
All features should work fine, including themes, with the exception of IP access control (because as far as Webmin is concerned, all connections will be coming from localhost).
This method can also be used to make Webmin accessible via an Apache virtual host, like
http://webmin.yourdomain.com/.
The steps to follow are :
Make sure mod_proxy is installed on your Apache webserver.
Add a virtual host to your Apache configuration file like:
<VirtualHost _default_>
ServerName webmin.yourdomain.com
ProxyPass / http://localhost:10000/
ProxyPassReverse / http://localhost:10000/
<Proxy *>
allow from all
</Proxy>
</VirtualHost>
In /etc/webmin/config, add the line referer=apachehost, where apachehost is the hostname from the URL used to access Webmin via Apache.
If the referer line already has some hosts listed, add apachehost to it.
Re-start Apache to apply the configuration.
No changes need to be made to /etc/webmin/config, because no prefix is appended to the URL path.
What is Usermin?
Usermin is a web-based interface for webmail, password changing, mail filters, fetchmail and much more.
It is designed for use by regular non-root users on a Unix system, and limits them to tasks that they would be able to perform if logged in via SSH or at the console.
Most users of Usermin are sysadmins looking for a simple webmail interface to offer their customers. Unlike most other webmail solutions, it can be used to change passwords, read email with no additional servers installed (like IMAP or POP3), and setup users’ Procmail configurations for forwarding, spam filtering and autoreponders.
Usermin also provides web interfaces for viewing and managing data in MySQL and PostgreSQL databases, editing Apache .htaccess configuration files, and running commands on the server.
The administrator has full control over which of these modules are available to users.
By far the easiest way to configure Usermin is via the Usermin Configuration module in Webmin.
All functionality can be managed via a browser, and because both products come from the same developer the management user interface is always up to date.
How to setup a cron job
This tutorial covers how to setup a Cron job. Cron is a service for executing scheduled commands.
It assumes you have first logged into Virtualmin.
Click Webmin on the top-left.
Click Services.
Click Scheduled Cron Jobs.
Click Create a new scheduled cron job.
Choose the user to run as, and input the username in Execute cron job as. To run as the administrative user, input root .
Enter the command to run into the Command field. For example, if you want to receive a list of all running processes, enter ps auxw for the command.
Normally, you can skip Input to command. That’s only used if your command requires input after it begins running.
Choose how frequently to run your command. By default, it will execute Hourly, meaning it will execute at the top of the hour, every hour.
To enable the Cron job, click Create.
Any output will be emailed to the root user.
