2.2、关闭SELinux
[root@linuprobe ~]# vi /etc/selinux/config
# 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 # change to disabled
# SELINUXTYPE= can take one of these two values:
# targeted - Targeted processes are protected,
# minimum - Modification of targeted policy. Only selected processes are protected.
# mls - Multi Level Security protection.
SELINUXTYPE=targeted
[root@linuprobe ~]# reboot # 重启时配置生效
3、三、更新系统，添加源仓库
[root@linuprobe ~]# yum -y update
[root@linuprobe ~]# yum -y install yum-plugin-priorities
[root@linuprobe ~]# yum -y install epel-release
[root@linuprobe ~]# yum -y install centos-release-scl-rh centos-release-scl
