SELinux 设置强制问题

我在带有 LAMP 堆栈的 CentOS 6.9 上，尝试设置 SELinux = enforcing，/etc/selinux/config
但是在 **重新启动** 并检查后sestatus我仍然得到SELinux status:disabled
然后我尝试运行setenforce Permissive它返回setenforce: SELinux is disabled
它也setsebool httpd_can_sendmail 1返回相同的消息我验证了 配置文件内容

之间的链接：ln -s /etc/selinux/config /etc/sysconfig/selinux

# 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 - SELinux is fully disabled.
SELINUX=enforcing

# SELINUXTYPE= type of policy in use. Possible values are:
#       targeted - Only targeted network daemons are protected.
#       strict - Full SELinux protection.
SELINUXTYPE=targeted

为什么命令不起作用？如何启用 SELinux？

编辑，我尝试启用 SELinux 的原因是因为这篇文章：https://stackoverflow.com/questions/8341678/ph​​p-mail-function-not-working-on-centos-server
