Pre-Install Plesk 7.5 Reloaded : Disabled CentOS Firewall and SELINUX

UPDATE

CentOS Firewall needs to be disabled. Plesk has its own firewall, and CentOS firewall can interfere, blocking an access to Plesk Administrator Site . I suggest to run it before install Plesk (pre-install)
To disabled it, run :

# system-config-securitylevel
Select disabled and press OK

To check that CentOS firewall has been disabled, run :

# iptables -L
Output :

Chain INPUT (policy ACCEPT)
target prot opt source destinationChain FORWARD (policy ACCEPT)
target prot opt source destination

Chain OUTPUT (policy ACCEPT)
target prot opt source destination


SELinux is a security extension of CentOS that should provide extended security. SELinux needs to be disabled

Edit /etc/selinux/config
# vi /etc/selinux/config
Set SELINUX=disabled

# This file controls the state of SELinux on the system.
# SELINUX= can take one of these three values:
# enforcing - SELinux security policy is enforced.
# permissive - SELinux prints warnings instead of enforcing.
# disabled - SELinux is fully disabled.
SELINUX=disabled
# SELINUXTYPE= type of policy in use. Possible values are:
# targeted - Only targeted network daemons are protected.
# strict - Full SELinux protection.
SELINUXTYPE=targeted

Reboot CentOS
# reboot
or
# shutdown -r now
