Docker离线安装

1. 安装目录

   mkdir /opt/docker && cd /opt/docker
   

2. 安装包下载

   yum -y install wget && wget https://download.docker.com/linux/static/stable/x86_64/docker-24.0.7.tgz
   注意：https://download.docker.com/linux/static/stable/x86_64 获取最新版本下载链接并替换(docker-xxx.tgz)
   

3. 安装包解压

   tar -xvf docker-24.0.7.tgz && cp docker/* /usr/bin/
   

4. 注册服务

   sudo tee /usr/lib/systemd/system/docker.service <<-'EOF'
   [Unit]
   Description=Docker Application Container Engine
   Documentation=http://docs.docker.com
   After=network.target docker.socket
   [Service]
   Type=notify

                   -H unix:///var/run/docker.sock \
                   --selinux-enabled=false \
                   --log-opt max-size=1g
   ExecReload=/bin/kill -s HUP $MAINPID

   # in the kernel. We recommend using cgroups to do container-local accounting.
   LimitNOFILE=infinity
   LimitNPROC=infinity

   # kill only the docker process, not all processes in the cgroup
   KillMode=process
   Restart=on-failure
   [Install]
   WantedBy=multi-user.target
   EOF
   

5. 镜像源配置

   sudo mkdir -p /etc/docker/
   sudo tee /etc/docker/daemon.json <<-'EOF'
   {
     "registry-mirrors": ["https://8q5nyauc.mirror.aliyuncs.com"]
   }
   EOF
   sudo systemctl daemon-reload
   sudo systemctl restart docker
   

6. 启动服务

   启动：systemctl start docker
   停止：systemctl stop docker
   重启：systemctl restart docker
   开机启动：systemctl enable docker
