The Perfect Server - CentOS 5.3 i386 [ISPConfig 2] - 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...

hi Falko,

Shouldn't the following command:

chmod 600 smtpd.key

be moved a bit downward, as the command currently following it:

mv -f smtpd.key.unencrypted smtpd.key

 resets smtpd.key-s 600 permissions back to 644?

Dear Mr. Timme. I just performed the 5.1 installation yesterday. I guess I was feeling challenging and re-did a an old computer I have and where I run my home phone system.

No, I'm no expert, just a very amateur computer and technology attracted person.

The reason for writing to you today is just to say thank you and what a fantastic job you have done with these tutorial. I had used the same tutorial to just mid capacities about a year ago and yesterday I noticed I had learned a bit more so things went smoother but my amazement is in the care you put into them. Every single command as clockwork and at the end you know you have an excellent server setup.

As I'm writing to you I'm downloading 5.3 just because I ran into your latest tutorial. It's been raining here in S. Florida so, if my download goes ok I just might re-do the old box with a new 5.3.

Thank you so much. It is people like you that make the internet the beauty it is.

NOTE: when you complete this howto i always install ispconfig with wget

1. cd /tmp

2. wget

3. tar xvfz ISPConfig-2.2.34.tar*

4. cd /install_ispconfig

5. ./setup


Think this is all....
