The Perfect Server - CentOS 6.2 x86_64 With Apache2 [ISPConfig 3] - Page 3
4 Adjust /etc/hosts
Next we edit /etc/hosts. Make it look like this:
5 Configure The Firewall
(You can skip this chapter if you have already disabled the firewall at the end of the basic system installation.)
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).
and disable the firewall.
To check that the firewall has really been disabled, you can run
afterwards. The output should look like this:
[root@server1 ~]# iptables -L
6 Disable SELinux
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 (this is a must if you want to install ISPConfig later on).
Edit /etc/selinux/config and set SELINUX=disabled:
Afterwards we must reboot the system:
7 Enable Additional Repositories And Install Some Software
First we import the GPG keys for software packages:
rpm --import /etc/pki/rpm-gpg/RPM-GPG-KEY*
Then we enable the RPMforge and EPEL repositories on our CentOS system as lots of the packages that we are going to install in the course of this tutorial are not available in the official CentOS 6.2 repositories:
rpm --import http://dag.wieers.com/rpm/packages/RPM-GPG-KEY.dag.txt
(If the above link doesn't work anymore, you can find the current version of rpmforge-release here: http://packages.sw.be/rpmforge-release/)
rpm --import https://fedoraproject.org/static/0608B895.txt
yum install yum-priorities
... and add the line priority=10 to the [epel] section:
Then we update our existing packages on the system:
Now we install some software packages that are needed later on:
yum groupinstall 'Development Tools'
(If you have chosen a different partitioning scheme than I did, you must adjust this chapter so that quota applies to the partitions where you need it.)
To install quota, we run this command:
yum install quota
Edit /etc/fstab and add ,usrjquota=aquota.user,grpjquota=aquota.group,jqfmt=vfsv0 to the / partition (/dev/mapper/vg_server1-lv_root):
mount -o remount /
to enable quota.
9 Install Apache, MySQL, phpMyAdmin
We can install the needed packages with one single command:
yum install ntp httpd mod_ssl mysql-server php php-mysql php-mbstring phpmyadmin
