重启服务器后，确认SELINUX和防火墙是否被关闭

[root@localhost ~]# sestatus 
SELinux status:                 disabled // 显示disabled表示selinux已经被关闭了，没有加载
[root@localhost ~]# iptables -vnL
Chain INPUT (policy ACCEPT 0 packets, 0 bytes)
 pkts bytes target     prot opt in     out     source               destination         

Chain FORWARD (policy ACCEPT 0 packets, 0 bytes)
 pkts bytes target     prot opt in     out     source               destination         

Chain OUTPUT (policy ACCEPT 0 packets, 0 bytes)
