在Nginx容器安裝Keepalived後端項目雙機熱備

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

apt-get install vim


        再次以前要配置VIP虛擬IP   docker network create --subnet=192.168.99.151/16 net1
        docker network ls
                                 這裏還要設置下vim 沒法粘貼問題

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





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