SELinuxとは? : 強制アクセス制御を実現するセキュリティ機構
Security-Enhanced-Linux
アクセス制御に使う

$ getenforce
Enforcing
$ 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
Memory protection checking: actual (secure)
Max kernel policy version: 33

### 一時的に無効化
$ sudo setenforce 0
$ getenforce
Permissive

### 恒久的に無効化
$ sudo cp -piv /etc/selinux/config /etc/selinux/config.`date “+%Y%m%d”`
$ sudo vi /etc/selinux/config

# SELINUX=enforcing
SELINUX=disabled

$ sudo systemctl restart httpd
$ systemctl status httpd.service

なるほど
