  15.              # This file controls the state of SELinux on the system.
  16.              # SELINUX= can take one of these three values:
  17.              #     enforcing - SELinux security policy is enforced.
  18.              #     permissive - SELinux prints warnings instead of enforcing.
  19.              #     disabled - No SELinux policy is loaded.
  20.              SELINUX=enforcing         修改为"SELINUX=disabled"
  21.              # SELINUXTYPE= can take one of three values:
  22.              #     targeted - Targeted processes are protected,
  23.              #     minimum - Modification of targeted policy. Only selected processes are protected.
  24.              #     mls - Multi Level Security protection.
  25.              SELINUXTYPE=targeted
