一、安装docker安装需要的软件包yum-util 提供yum-config-manager功能另外两个是devicemapper驱动依赖的sudoyuminstall-yyum-utils device-mapper-persistent-data lvm2设置yum源国内阿里云选择下面的命令sudoyum-config-manager --add-repo http://mirrors.aliyun.com/docker-ce/linux/centos/docker-ce.repo 国内sudoyum-config-manager --add-repo https://download.docker.com/linux/centos/docker-ce.repo(国外)安装dockersudoyuminstalldocker-ce启动并加入开机启动sudosystemctl startdockersudosystemctlenabledocker二、安装docker-compose下载docker-composea. 1.25.4版本curl-Lhttps://github.com/docker/compose/releases/download/1.25.4/docker-compose-uname-s-uname-m-o/usr/local/bin/docker-composeb. 最新版本sudocurl-Lhttps://github.com/docker/compose/releases/latest/download/docker-compose-$(uname-s)-$(uname-m)-o/usr/local/bin/docker-composec.本地方案如果curl下载很慢可以手动从网址https://github.com/docker/compose/releases 下载最新版本的安装包比如docker-compose-linux-x86_64 上传到Linux服务器的root目录并执行下面的命令sudomv/root/docker-compose-linux-x86_64 /usr/local/bin/docker-compose授权docker-composechmodx /usr/local/bin/docker-compose验证docker-composeversion
