Centos 7 安装docker
环境
- CentOS Linux release 7.6.1810 (Core)
创建安装脚本
新建一个install_docker.sh文件，并写入以下内容：
#!/usr/bin/bash # # 卸载老版本 sudo yum remove docker docker-client docker-client-latest docker-common docker-latest docker-latest-logrotate docker-logrotate docker-engine # 安装必要的工具包 sudo yum install -y yum-utils device-mapper-persistent-data lvm2 # 添加软件源信息 sudo yum-config-manager --add-repo https://download.docker.com/linux/centos/docker-ce.repo # 安装docker-ce sudo yum -y install docker-ce docker-ce-cli containerd.io # 启动docker服务 sudo systemctl start docker
然后执行该脚本：
sh install_docker.sh
然后根据提示输入密码就OK了。
屏幕输出信息
过程如下：
