2.2. 将 SELinux 更改为 permissive 模式

流程

1. 在文本编辑器中打开 /etc/selinux/config 文件，并配置 SELINUX=permissive 选项：

   # 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=permissive
   # SELINUXTYPE= can take one of these two values:
   #       targeted - Targeted processes are protected,
   #       mls - Multi Level Security protection.
   SELINUXTYPE=targeted
