3:安装docker引擎
yum install docker-ce docker-ce-cli containerd.io
4:查看版本
[ yum.repos.d]# docker version Client: Docker Engine - Community # 这个是客户端 Version: 19.03.12 API version: 1.40 Go version: go1.13.10 Git commit: 48a66213fe Built: Mon Jun 22 15:46:54 2020 OS/Arch: linux/amd64 Experimental: false Server: Docker Engine - Community # 这个是服务端,且这个是社区版服务端 Engine: Version: 19.03.12 API version: 1.40 (minimum version 1.12) Go version: go1.13.10 Git commit: 48a66213fe Built: Mon Jun 22 15:45:28 2020 OS/Arch: linux/amd64 Experimental: false containerd: Version: 1.2.13 GitCommit: 7ad184331fa3e55e52b890ea95e65ba581ae3429 runc: Version: 1.0.0-rc10 GitCommit: dc9208a3303feef5b3839f4323d9beb36df0a9dd docker-init: Version: 0.18.0 GitCommit: fec3683 [ yum.repos.d]#
5:开机启动,查看状态
systemctl start docker # 启动服务 systemctl status docker # 查看状态 systemctl enable docker # 开机启动
6:修改配置文件
查看配置文件所在位置
查看yum安装docker服务的文件位置 # 首先查看安装的docker的软件 [ ~]# rpm -qa | grep docker* docker-ce-cli-19.03.12-3.el7.x86_64 docker-ce-19.03.12-3.el7.x86_64 #查看docker-ce服务端安装的包位置 [ ~]# rpm -ql docker-ce-19.03.12-3.el7.x86_64 /usr/bin/docker-init # 初始化 /usr/bin/docker-proxy # 与网络有关的程序 这三个是管理docker服务端的命令 /usr/bin/dockerd # 后台程序 /usr/lib/systemd/system/docker.service # 服务启动的配置文件 /usr/lib/systemd/system/docker.socket # 只是启动了一个端口或者是一个sockert [ ~]# rpm -ql docker-ce-19.03.12-3.el7.x86_64 # 查看docker-cli服务端安装软件包的位置 [ ~]# rpm -ql docker-ce-cli-19.03.12-3.el7.x86_64 目录太多我就不复制粘贴了
配置文件
/etc/docker/key.json # 这个是docker配置文件 配置项稍后再说
