最近遇到一个奇怪的问题，有关linux selinux的设置问题


一个同学在配置selinux的时候，把配置改成了如下

​​​​

# 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 these two values:
#     targeted - Targeted processes are protected,
#     mls - Multi Level Security protection.
SELINUXTYPE=disabled

​也就是把SELINUXTYPE的值改成了disabled，结果发现服务器启动失败了

Failed to load SELinux policy_selinux


解决方法：

系统启动时候进入按e进入

Failed to load SELinux policy_linux_02


找到下边这一行加上selinux=0

Failed to load SELinux policy_linux_03


按键ctrl+x重启即可，正常进去之后修改selinux配置，改为如下即可


# 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
