Disable SELinux
In some case, SELinux feature in Linux may block some needed protocols (e.g.,http) unexpectedly.
So we recommend to disable SELinux feature at installation phase.
Here is an example to disable SELinux on CentOS.
Disable SELinux temporary
From the command line, you can set the following command.
# setenforce 0
Disable SELinux permanently
From the command line, you can edit the “/etc/sysconfig/selinux” file.
Change to “SELINUX=disabled”
=/etc/sysconfig/selinux==============================
# 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 - No SELinux policy is loaded.
SELINUX=disabled
# SELINUXTYPE= can take one of these two values:
# targeted - Targeted processes are protected,
# mls - Multi Level Security protection.
SELINUXTYPE=targeted
After save the file, you need to restart Linux.
