看提示中提到SElinux，检查发现确实没有关闭SELinux

[[email protected] data]# getenforce
Enforcing
[[email protected] data]# sestatus
SELinux status:                 enabled
SELinuxfs mount:                /sys/fs/selinux
SELinux root directory:         /etc/selinux
Loaded policy name:             targeted
Current mode:                   enforcing
Mode from config file:          enforcing
Policy MLS status:              enabled
Policy deny_unknown status:     allowed
Max kernel policy version:      31

关闭SELinux

1.以root权限远程连接ECS实例。连接方式请参见连接方式概述。

2.运行命令getenforce，验证SELinux状态。
	返回状态如果是enforcing，表明SELinux已开启。

3.选择临时关闭或者永久关闭SELinux。
	执行命令setenforce 0临时关闭SELinux。
	永久关闭SElinux。

[[email protected] data]# getenforce
Enforcing

# 临时关闭 SELinux
[[email protected] data]# setenforce 0
[[email protected] data]# 
[[email protected] data]# 
[[email protected] data]# getenforce
Permissive

• a.运行以下命令，编辑SELinux的config文件。
  vim /etc/selinux/config
• b.找到SELINUX=enforcing，按i进入编辑模式，将参数修改为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 - No SELinux policy is loaded.
SELINUX=enforcing
# SELINUXTYPE= can take one of three values:
# targeted - Targeted processes are protected,
# minimum - Modification of targeted policy. Only selected processes are protected. 
# mls - Multi Level Security protection.
SELINUXTYPE=targeted

我已经修改好了

• c.修改完成后，按下键盘Esc键，执行命令:wq，保存并退出文件。

• d.重启ECS实例。

shutdown -r now

• e.重启后，运行命令getenforce，验证SELinux状态为disabled，表明SELinux已关闭。
