就是因为没关selinux

解决办法

root@centos ~]# getenforce　←　SELinux状態確認
Enforcing　←　SELinux有効


[root@centos ~]# setenforce 0　←　SELinux無効化


[root@centos ~]# getenforce　←　SELinux状態確認
Permissive　←　SELinux無効


[root@centos ~]# vi /etc/sysconfig/selinux　←　SELinux設定ファイル編集
SELINUX=enforcing
↓
SELINUX=disabled　←　システム起動時にSELinuxを無効化
