Pre-installed system for VPS - CentOS Web Administration

And here is another manual for the work with the virtual servers of Coolhousing. Now it is the pre-installed system with administration directly from the VPS of the admin on the CentOS Linux platform. Every customer can install this web panel to their server by a single click, any time and free of charge. It is so easy and the server administration can be really mastered by anybody thanks to this interface.

This administration panel, directly integrated in the VPS Admin web interface, is available completely free to all VPS users of the Coolhousing company. The only condition is the direct installation of the pre-prepared system based on the CentOS Linux distribution.

By means of this interface it is possible to perform basic administration actions on the entire server – change the administrator (root) password, set the firewall or adjust the settings of PHP or Apache. All this very easily from the environment of well-arranged web forms.

For completeness, here is the full description of everything that can be adjusted from the environment of this VPS web administration:

  • change the password of the root user,
  • set domains and subdomains and/or redirect them,
  • create or cancel FTP accounts,
  • create or remove MySQL or PostgreSQL database,
  • create or delete a CRON task,
  • set the firewall for IPv4 as well as IPv6,
  • modify the values of variables in PHP,
  • create customized error pages.

The server administration environment can be accessed easily from the VPS Admin interface at

If you want to put this integrated administration service newly into operation and you do not have it yet, it is necessary to perform the direct installation of the pre-prepared system. If you have been using a system on VPS already, you will lose all data, because the system will be completely reinstalled.

The installation of this system can be performed from the Server administration -> System tab.

System tab

The first option that we can face in the pre-prepared system administration is the change of password of the root user directly on the server. This can be done in the Server administration -> System tab.

CentOS root

All other options are in the Content management tab.

The first subtab, WWW and FTP, enables to restart the Apache web server, create a (sub)domain for web pages or create a new user account for FTP.

To create a domain or subdomain, select the WWW tab and click on the Create (sub)domain button.

Apache settings Create redirection

Similarly it is possible to set the redirection of a domain by means of the Create redirection button.

In the FTP tab you can create and FTP account for a user. Just click on the Create ftp account button and enter the needed data.

FTP #1 FTP #2

Another service you can administer from the web administration environment is the SQL server. Here you can use the MySQL and PostgreSQL databases. The settings are the same in both cases, only the tab with the database identification differs.

MySQL, PostgreSQL #1 MySQL, PostgreSQL #2

If you need to perform a periodic operation on the server, you can do so by means of setting the required cron task. This is done by means of the CRON tab.


Here click on the Create CRON button and enter the needed data. It is obvious that the script performing the respective task must be on a URL accessible from the virtual server.


In the last tab, Advanced, you will find the possibility to set the firewall for both IPv4 and IPv6, possibility to modify the variables at PHP or to set your own error pages.

The control of the firewall is very ergonomic, so you will get oriented easily. Just enter the respective data after pressing the Create rule button.

IP settings

In the same way you can then modify the respective items at PHP. For example, if you know that you will need to increase the memory_limit from the default 128 MB to 256 MB, just overwrite the value from 128M to 256M and press the Save button to confirm.


If the setting using the form is not sufficient to you, you can directly edit the php.ini file by means of the Expert settings tab.

Expert PHP.ini

The last item is the Error pages, which you can customize as you wish. However, in most cases you can do without any modifications.
