Docker基本命令
更新软件包
yum -y update安装Docker虚拟机
yum install -y docker运行、重启、关闭Docker虚拟机
service docker start
service docker stop搜索镜像
docker search 镜像名称下载镜像
docker pull 镜像名称查看镜像
docker images删除镜像
docker rmi 镜像名称运行容器
docker run 启动参数 镜像名称查看容器列表
docker ps -a停止、挂起、恢复容器
docker stop 容器ID
docker pause 容器ID
docker unpase 容器ID查看容器信息
docker inspect 容器ID删除容器
docker rm 容器ID数据卷管理

后端部署方案
数据库集群部署方案：
Redis集群部署方案
安装PXC集群，负载均衡，双机热备
安装PXC镜像
docker pull percona/percona-xtradb-cluster为PXC镜像改名
docker tag percona/percona-xtradb-cluster pxc创建net1网段
docker network create --subnet=172.18.0.0/16 net1创建5个数据卷
docker volume create --name v1
docker volume create --name v2
docker volume create --name v3
docker volume create --name v4
docker volume create --name v5创建备份数据卷（用于热备份数据）
docker volume create --name backup创建5节点的PXC集群
注意，每个MySQL容器创建之后，因为要执行PXC的初始化和加入集群等工作，耐心等待1分钟左右再用客户端连接MySQL。另外，必须第1个MySQL节点启动成功，用MySQL客户端能连接上之后，再去创建其他MySQL节点。
#创建第1个MySQL节点
docker run -d -p 3306:3306 -e MYSQL_ROOT_PASSWORD=abc123456
-e CLUSTER_NAME=PXC
-e XTRABACKUP_PASSWORD=abc123456
-v v1:/var/lib/mysql -v backup:/data --privileged
--name=node1
--net=net1
--ip 172.18.0.2 pxc
#创建第2个MySQL节点
