Centos7 安装 Docker
2年前写过一篇安装Docker的文档记录，当时安装有些麻烦，现在安装docker就非常容易了，而且安装完docker，自动也安装了docker compose，不用再去执行指令单独安装docker compose了，所以现在再记录一下，便于查看。
1、安装yum-utils包
yum install -y yum-utils
[root@localhost ~]# yum install -y yum-utils

2、配置Docker存储库
yum-config-manager --add-repo https://download.docker.com/linux/centos/docker-ce.repo
[root@localhost ~]# yum-config-manager --add-repo https://download.docker.com/linux/centos/docker-ce.repo
Loaded plugins: fastestmirror
adding repo from: https://download.docker.com/linux/centos/docker-ce.repo
grabbing file https://download.docker.com/linux/centos/docker-ce.repo to /etc/yum.repos.d/docker-ce.repo
repo saved to /etc/yum.repos.d/docker-ce.repo
3、安装Docker Engine 与 Continerd
yum install docker-ce docker-ce-cli containerd.io
注：安装过程中会有 Is this ok [y/d/N] 的提示，输入y即可，或安装命令加-y，如下
yum install -y docker-ce docker-ce-cli containerd.io
[root@localhost ~]# yum install docker-ce docker-ce-cli containerd.io

4、检查是否安装成功 - 查看Docker版本
docker version
[root@localhost ~]# docker version
Client: Docker Engine - CommunityVersion: 24.0.5API version: 1.43Go version: go1.20.6Git commit: ced0996Built: Fri Jul 21 20:39:02 2023OS/Arch: linux/amd64Context: default
Cannot connect to the Docker daemon at unix:///var/run/docker.sock. Is the docker daemon running?
查看Docker compose 版本
安装docker时，直接安装了docker compose.
docker compose version
[root@localhost ~]# docker compose version
Docker Compose version v2.20.2
5、启动Docker
systemctl start docker
[root@localhost ~]# systemctl start docker
[root@localhost ~]# docker images # 查看镜像
REPOSITORY TAG IMAGE ID CREATED SIZE
[root@localhost ~]# docker ps # 查看容器命令
CONTAINER ID IMAGE COMMAND CREATED STATUS PORTS NAMES6、设置开机启动
systemctl enable docker
[root@localhost ~]# systemctl enable docker
Created symlink from /etc/systemd/system/multi-user.target.wants/docker.service to /usr/lib/systemd/system/docker.service.
