关闭内核级安检

[[email protected] ~]#setenforce 0

永久关闭内核级安检可以修改

[[email protected] ]# vim /etc/selinux/config

# This file controls the state of SELinux on the system.

#       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

切换用户，进入安装目录，执行脚本进行图形安装

※执行脚本前时务必用创建的帐号登陆下图形界面（或者root用户执行xhost +不好使时用）

[[email protected] ~]# su oracle
[[email protected] ~]$ cd /u01/database/
[[email protected] database]$ ./runInstaller
