2.关闭防火墙和selinux
[root@localhost ~]# systemctl status firewalld //查看当前防火墙状态。
[root@localhost ~]# systemctl stop firewalld //关闭当前防火墙。
[root@localhost ~]# systemctl disable firewalld //开机防火墙不启动。
[root@localhost ~]# getenforce
Enforcing
[root@localhost ~]# setenforce 0 //关闭selinux
[root@localhost ~]# vi /etc/sysconfig/selinux //编辑实现开机不启动selinux
.....
SELINUX=disabled
3. 开机自动开启网络
[root@localhost ~]# cd /etc/sysconfig/network-scripts
[root@localhost network-scripts]# ll //找对应网卡
