创建两个Haproxy容器
#创建第1个Haproxy负载均衡服务器docker run -it -d -p 4001:8888 -p 4002:3306-v /home/soft/haproxy:/usr/local/etc/haproxy--name h1 --privileged --net=net1 --ip 172.18.0.7 haproxy#进入h1容器，启动Haproxydocker exec -it h1 bashhaproxy -f /usr/local/etc/haproxy/haproxy.cfg#创建第2个Haproxy负载均衡服务器docker run -it -d -p 4003:8888 -p 4004:3306-v /home/soft/haproxy:/usr/local/etc/haproxy--name h2 --privileged --net=net1 --ip 172.18.0.8 haproxy#进入h2容器，启动Haproxydocker exec -it h2 bashhaproxy -f /usr/local/etc/haproxy/haproxy.cfgHaproxy容器内安装Keepalived，设置虚拟IP
