三、使用阿里云Docker CE镜像安装Docker
1、SSH连接CentOS 7系统
2、基于CentOS 7安装配置Docker（使用 yum 进行安装）
# step 1: 安装必要的一些系统工具 sudo yum install -y yum-utils device-mapper-persistent-data lvm2 # Step 2: 添加软件源信息 sudo yum-config-manager --add-repo https://mirrors.aliyun.com/docker-ce/linux/centos/docker-ce.repo # Step 3 sudo sed -i 's+download.docker.com+mirrors.aliyun.com/docker-ce+' /etc/yum.repos.d/docker-ce.repo # Step 4: 更新并安装Docker-CE sudo yum makecache fast sudo yum -y install docker-ce # Step 4: 开启Docker服务 sudo service docker start # 注意： # 官方软件源默认启用了最新的软件，您可以通过编辑软件源的方式获取各个版本的软件包。例如官方并没有将测试版本的软件源置为可用，您可以通过以下方式开启。同理可以开启各种测试版本等。 # vim /etc/yum.repos.d/docker-ce.repo # 将[docker-ce-test]下方的enabled=0修改为enabled=1 # # 安装指定版本的Docker-CE: # Step 1: 查找Docker-CE的版本: # yum list docker-ce.x86_64 --showduplicates | sort -r # Loading mirror speeds from cached hostfile # Loaded plugins: branch, fastestmirror, langpacks # docker-ce.x86_64 17.03.1.ce-1.el7.centos docker-ce-stable # docker-ce.x86_64 17.03.1.ce-1.el7.centos @docker-ce-stable # docker-ce.x86_64 17.03.0.ce-1.el7.centos docker-ce-stable # Available Packages # Step2: 安装指定版本的Docker-CE: (VERSION例如上面的17.03.0.ce.1-1.el7.centos) # sudo yum -y install docker-ce-[VERSION]
- 1、安装必要的一些系统工具
yum install -y yum-utils device-mapper-persistent-data lvm2
- 2、添加软件源信息
yum-config-manager --add-repo https://mirrors.aliyun.com/docker-ce/linux/centos/docker-ce.repo
[root@centos yum.repos.d]# cat docker-ce.repo [docker-ce-stable] name=Docker CE Stable - $basearch baseurl=https://mirrors.aliyun.com/docker-ce/linux/centos/$releasever/$basearch/stable enabled=1 gpgcheck=1 gpgkey=https://mirrors.aliyun.com/docker-ce/linux/centos/gpg [docker-ce-stable-debuginfo] name=Docker CE Stable - Debuginfo $basearch baseurl=https://mirrors.aliyun.com/docker-ce/linux/centos/$releasever/debug-$basearch/stable enabled=0 gpgcheck=1 gpgkey=https://mirrors.aliyun.com/docker-ce/linux/centos/gpg [docker-ce-stable-source] name=Docker CE Stable - Sources baseurl=https://mirrors.aliyun.com/docker-ce/linux/centos/$releasever/source/stable enabled=0 gpgcheck=1 gpgkey=https://mirrors.aliyun.com/docker-ce/linux/centos/gpg [docker-ce-test] name=Docker CE Test - $basearch baseurl=https://mirrors.aliyun.com/docker-ce/linux/centos/$releasever/$basearch/test enabled=0 gpgcheck=1 gpgkey=https://mirrors.aliyun.com/docker-ce/linux/centos/gpg [docker-ce-test-debuginfo] name=Docker CE Test - Debuginfo $basearch baseurl=https://mirrors.aliyun.com/docker-ce/linux/centos/$releasever/debug-$basearch/test enabled=0 gpgcheck=1 gpgkey=https://mirrors.aliyun.com/docker-ce/linux/centos/gpg [docker-ce-test-source] name=Docker CE Test - Sources baseurl=https://mirrors.aliyun.com/docker-ce/linux/centos/$releasever/source/test enabled=0 gpgcheck=1 gpgkey=https://mirrors.aliyun.com/docker-ce/linux/centos/gpg [docker-ce-nightly] name=Docker CE Nightly - $basearch baseurl=https://mirrors.aliyun.com/docker-ce/linux/centos/$releasever/$basearch/nightly enabled=0 gpgcheck=1 gpgkey=https://mirrors.aliyun.com/docker-ce/linux/centos/gpg [docker-ce-nightly-debuginfo] name=Docker CE Nightly - Debuginfo $basearch baseurl=https://mirrors.aliyun.com/docker-ce/linux/centos/$releasever/debug-$basearch/nightly enabled=0 gpgcheck=1 gpgkey=https://mirrors.aliyun.com/docker-ce/linux/centos/gpg [docker-ce-nightly-source] name=Docker CE Nightly - Sources baseurl=https://mirrors.aliyun.com/docker-ce/linux/centos/$releasever/source/nightly enabled=0 gpgcheck=1 gpgkey=https://mirrors.aliyun.com/docker-ce/linux/centos/gpg
- 3、配置Docker -ce.repo镜像
sudo sed -i 's+download.docker.com+mirrors.aliyun.com/docker-ce+' /etc/yum.repos.d/docker-ce.repo
- 4、更新并安装Docker-CE
sudo yum makecache fast sudo yum -y install docker-ce
[root@centos yum.repos.d]# yum makecache fast Loaded plugins: fastestmirror Loading mirror speeds from cached hostfile * base: mirrors.aliyun.com * extras: mirrors.aliyun.com * updates: mirrors.aliyun.com base | 3.6 kB 00:00:00 docker-ce-stable | 3.5 kB 00:00:00 extras | 2.9 kB 00:00:00 updates | 2.9 kB 00:00:00 (1/2): docker-ce-stable/7/x86_64/updateinfo | 55 B 00:00:00 (2/2): docker-ce-stable/7/x86_64/primary_db | 69 kB 00:00:00 Metadata Cache Created [root@centos yum.repos.d]#
- 5、开启Docker服务
[root@centos yum.repos.d]# systemctl start docker [root@centos yum.repos.d]# systemctl status docker
3、检查Docker是否安装成功
[root@centos yum.repos.d]# docker version Client: Docker Engine - Community Version: 20.10.11 API version: 1.41 Go version: go1.16.9 Git commit: dea9396 Built: Thu Nov 18 00:38:53 2021 OS/Arch: linux/amd64 Context: default Experimental: true Server: Docker Engine - Community Engine: Version: 20.10.11 API version: 1.41 (minimum version 1.12) Go version: go1.16.9 Git commit: 847da18 Built: Thu Nov 18 00:37:17 2021 OS/Arch: linux/amd64 Experimental: false containerd: Version: 1.4.12 GitCommit: 7b11cfaabd73bb80907dd23182b9347b4245eb5d runc: Version: 1.0.2 GitCommit: v1.0.2-0-g52b36a2 docker-init: Version: 0.19.0 GitCommit: de40ad0 [root@centos yum.repos.d]#
