cd /etc/sysconfig/network-scripts/
vim ifcfg-ens33

# 将190改为你的网关号
IPADDR="192.168.190.151"        #ip地址

systemctl restart network
systemctl stop firewalld
systemctl disable firewalld

IPV4开启

vi /etc/sysctl.conf
net.ipv4.ip_forward=1  #最下方添加这段代码
#重启network服务
systemctl restart network && systemctl restart docker
#查看是否修改成功 （备注：返回1，就是成功）
[root@docker-node2 ~]# sysctl net.ipv4.ip_forward
net.ipv4.ip_forward = 1
