1、个人资料没权限打开，你发现你用的都是root权限，目录都已经777了，还是打不开，这时就要考虑selinux了
2、尝试关闭selinux：
# setenforce 0
3、永久关闭selinux：
将里面的SELINUX=enforcing修改为disabled
[root@localhost 桌面]# cat /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
# SELINUXTYPE= can take one of three two values:
# targeted - Targeted processes are protected,
# minimum - Modification of targeted policy. Only selected processes are protected.
# mls - Multi Level Security protection.
SELINUXTYPE=targeted
4、重启系统
reboot
