  经查证，原来是selinux的问题，解决办法有两种如下：
1.使用命令setenforce 0临时将selinux关闭，恢复的话使用命令：setenforce 1
2.要么编辑/etc/selinux/config文件，如下：
# 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=enforcing
将SELINUX=enforcing修改为SELINUX=disabled后重新启动系统。
