服务器搭建docker等中间件
\#安装依赖\
  yum install -y yum-utils device-mapper-persistentdata lvm2\
\#配置yum源（⽐较慢,不⽤）\
\#yum-config-manager \ --add-repo \
\#<https://download.docker.com/linux/centos/dockerce.repo>
\
\#配置yum源 添加阿里云镜像仓库\
sudo yum-config-manager \
\--add-repo \
<http://mirrors.aliyun.com/docker-ce/linux/centos/docker-ce.repo>	
\
\#查看版本\
yum list docker-ce --showduplicates | sort -r
\#1. 安装docker 等仓库设置完成后，就可以安装Docker，如下命令安装最新版本
sudo yum install docker-ce docker-ce-cli containerd.io docker-compose-plugin
\
\#2. 查看docker版本\
docker -v\
\#3. 启动docker\
systemctl start docker\
\#4. 查看docker 启动状态\
systemctl status docker\
检查安装结果。\
docker info\
启动使⽤Docker\
systemctl start docker #运⾏Docker守护进程\
systemctl stop docker #停⽌Docker守护进程\
systemctl restart docker #重启Docker守护进程\
docker ps查看容器\
docker stop 容器id\
修改镜像仓库\
vim /etc/docker/daemon.json\
\#改为下⾯内容，然后重启docker\
{\
"registry-mirrors":\["<https://hub-mirror.c.163.com","https://registry.aliyuncs.com","https://registry.docker-cn.com","https://docker.mirrors.ustc.edu.cn>"]\
} #
# 重启docker
