在Nginx容器安装Keepalived后端项目双机热备

docker exec -it n1 bash
apt-get update
apt-get install keepalived 

apt-get install vim


        再次之前要配置VIP虚拟IP   docker network create --subnet=192.168.99.151/16 net1
        docker network ls
                                 这里还要设置下vim 无法粘贴问题

vi /etc/keepalived/keepalived.conf
启动keepalived
service keepalived start





docker run -it -d --name n2 -v /home/n2/nginx.conf:/etc/nginx/nginx.conf --net=host --privileged nginx
