离线安装docker

1. 解压文件

   tar -zxvf docker-20.10.9.tgz

2. 将解压后docker里的所有文件移至 /usr/bin/目录下

   cp docker/* /usr/bin/

3. 将docker注册为系统服务

   vim /etc/systemd/system/docker.service

4. 插入如下配置文件

   [Unit]
   Description=Docker Application Container Engine
   Documentation=https://docs.docker.com
   After=network-online.target firewalld.service
   Wants=network-online.target
    
   [Service]
   Type=notify
   ExecStart=/usr/bin/dockerd
   ExecReload=/bin/kill -s HUP $MAINPID
   LimitNOFILE=infinity
   LimitNPROC=infinity
   TimeoutStartSec=0
   Delegate=yes
   KillMode=process
   Restart=on-failure
   StartLimitBurst=3
   StartLimitInterval=60s
    
   [Install]
   WantedBy=multi-user.target

5. 给配置文件添加执行权限

    sudo chmod +x /etc/systemd/system/docker.service

6. 重载配置文件

    sudo systemctl daemon-reload

7. 操作docker

   //启动docker
   sudo systemctl start docker
   // 设置开机自启动
   sudo systemctl enable docker
   // 关闭开机自启动
   sudo systemctl disable docker
   // 查看docker是否为开机自启
   sudo systemctl is-enabled docker
   // 查看docker启动状态
   sudo systemctl status docker

安装docker-compose

1. 复制 Docker-Compose 到 /usr/local/bin

   sudo cp -f ./docker-compose-linux-x86_64 /usr/local/bin/docker-compose

2. 赋予 Docker-Compose 执行权限

   sudo chmod +x /usr/local/bin/docker-compose

3. 查看docker-compose版本

   docker-compose -v

安装docker-compose命令开机启动

1. 在 /etc/systemd/system/ 目录下创建一个新的服务文件

   sudo vim /etc/systemd/system/docker-compose-wens.service

2. 添加以下内容到该文件

注意WorkingDirectory改成项目的对应地址

    [Unit]
    Description=Docker Compose Application Service
    Requires=docker.service
    After=docker.service

    [Service]
    WorkingDirectory=/data/wens
    ExecStart=/usr/local/bin/docker-compose up -d
    ExecStop=/usr/local/bin/docker-compose down
    Restart=always
    TimeoutStartSec=0

    [Install]
    WantedBy=multi-user.target

3. 设置服务开机自启
   重新加载 system

   sudo systemctl daemon-reload

   启用服务开机自启动

   sudo systemctl enable docker-compose-wens

   启动服务

   sudo systemctl start docker-compose-wens

   验证服务是否启动

   sudo systemctl status docker-compose-wens
