提前准备：
	下载docker二进制包：https://download.docker.com/linux/static/stable/x86_64/docker-20.10.2.tgz
操作步骤一：
	#停止大屏docker容器
	[root@localhost easyv]# pwd
	/data/dtstack/easyv
	[root@localhost easyv]# bash app/bin/node_docker_run.sh stop
	[root@localhost easyv]# bash nginx/bin/nginx_docker_run.sh stop
	[root@localhost easyv]# bash mysql/bin/mysql_docker_run.sh stop
	[root@localhost easyv]# bash redis/bin/redis_docker_run.sh stop
	#停止docker服务并检查是否停止成功
	[root@localhost easyv]# systemctl  stop docker
	[root@localhost easyv]# systemctl  status docker

操作步骤二：
	#备份/usr/bin/docker* 8个docker文件到其他目录
	mkdir -p /opt/dtstack/docker_back
	mv /usr/bin/docker* /opt/dtstack/docker_back/
	#解压下载的二进制包
	tar zxf docker-20.10.2.tgz
	\cp -R docker/* /usr/bin/

操作步骤三：
	#启动docker服务
	[root@localhost easyv]# systemctl  start docker
	#检查docker版本是否符合预警范围
	[root@localhost ~]# docker -v
	##符合情况下，启动大屏docker容器，注意：和停止docker的顺序是反的
	[root@localhost easyv]# pwd
	/data/dtstack/easyv
	[root@localhost easyv]# bash redis/bin/redis_docker_run.sh stop
	[root@localhost easyv]# bash mysql/bin/mysql_docker_run.sh stop
	[root@localhost easyv]# bash nginx/bin/nginx_docker_run.sh stop
	[root@localhost easyv]# bash app/bin/node_docker_run.sh stop
操作步骤四：
	#检查大屏相关服务端口是否正常监听
	[root@localhost easyv]# ss -ntlp |grep mysql
	LISTEN     0      128       [::]:6608                  [::]:*                   users:(("mysqld",pid=6596,fd=29))
	LISTEN     0      70        [::]:33060                 [::]:*                   users:(("mysqld",pid=6596,fd=32))
	[root@localhost easyv]# ss -ntlp |grep redis
	LISTEN     0      128          *:6339                     *:*                   users:(("redis-server",pid=6715,fd=7))
	LISTEN     0      128       [::]:6339                  [::]:*                   users:(("redis-server",pid=6715,fd=6))
	[root@localhost easyv]# ss -ntlp |grep nginx
	LISTEN     0      128          *:3000                     *:*                   users:(("nginx",pid=7360,fd=8),("nginx",pid=7324,fd=8))
	LISTEN     0      128          *:8000                     *:*                   users:(("nginx",pid=7360,fd=7),("nginx",pid=7324,fd=7))
	[root@localhost easyv]# ss -ntlp |grep node
	LISTEN     0      128       [::]:1337                  [::]:*                   users:(("node",pid=20557,fd=58))
	LISTEN     0      128       [::]:1315                  [::]:*                   users:(("node",pid=20557,fd=57))
	[root@localhost easyv]# ss -ntlp |grep app
	LISTEN     0      128       [::]:1314                  [::]:*                   users:(("app",pid=20670,fd=24))
	[root@localhost easyv]#
