rpm -qa | grep ssh

注：若没安装SSH则可输入:

yum install openssh-server

Step2启动SSH服务。

1.systemctl restart  sshd

2.systemctl start sshd

Step3查看是否启动22端口

netstat -antp | grep sshd

Step4设置SSH开机启动

systemctl enable sshd

Centos-Static ip address-configuration

Step1配置静态IP地址

vi /etc/sysconfig/network-scripts/ifcfg-eno-网卡数字

Step2修改BootProto为Static，同时添加IPADDR、NETMASK、GATEWAY

Step3修改完成后，重启网络

service network restart

注：出现如下错误，直接重启Centos即可

Restarting network (via systemctl):  Job for network.service failed because the control process exited with error code. See "systemctl status network.service" and "journalctl -xe"

Step4设置DNS

vi /etc/resolv.conf

nameserver 8.8.8.8
nameserver 114.114.114.114
