The Perfect Server - CentOS 5.3 x86_64 [ISPConfig 3] - Page 2
Now we select the software we want to install. Select nothing but Server (uncheck everything else). Also don't check Packages from CentOS Extras. Then check Customize now, and click on Next:
Now we must select the package groups we want to install. Select Editors, Text-based Internet, Development Libraries, Development Tools, DNS Name Server, FTP Server, Mail Server, MySQL Database, Server Configuration Tools, Web Server, Administration Tools, Base, and System Tools (unselect all other package groups) and click on Next:
The installer checks the dependencies of the selected packages:
Click on Next to start the installation:
The hard drive is being formatted:
The installation begins. This will take a few minutes:
Finally, the installation is complete, and you can remove your CD or DVD from the computer and reboot it:
After the reboot, you will see this screen. Select Firewall configuration and hit Run Tool:
I want to install ISPConfig at the end of this tutorial which comes with its own firewall. That's why I disable the default CentOS firewall now. Of course, you are free to leave it on and configure it to your needs (but then you shouldn't use any other firewall later on as it will most probably interfere with the CentOS firewall).
SELinux is a security extension of CentOS that should provide extended security. In my opinion you don't need it to configure a secure system, and it usually causes more problems than advantages (think of it after you have done a week of trouble-shooting because some service wasn't working as expected, and then you find out that everything was ok, only SELinux was causing the problem). Therefore I disable it, too (this is a must if you want to install ISPConfig later on). Hit OK afterwards:
Then leave the Setup Agent by selecting Exit:
Then log in as root and reboot the system so that your changes can be applied:
Now, on to the configuration...
