1.使用场景

在互联网的服务器上可以直接使用yum命令安装docker,但是如果在无网的服务器上，就只能使用离线安装包了

2. 安装

  1. docker离线包下载地址
  2. 准备好docker-service文件

    注意：这里的配置文件里面的ExecStart将docker的存储路径设置成为了/work/docker

  1. [Unit]
  2. Description=Docker Application Container Engine
  3. Documentation=https://docs.docker.com
  4. After=network-online.target firewalld.service
  5. Wants=network-online.target
  7. [Service]
  8. Type=notify
  9. # the default is not to use systemd for cgroups because the delegate issues still
  10. # exists and systemd currently does not support the cgroup feature set required
  11. # for containers run by docker
  12. ExecStart=/usr/bin/dockerd  --graph /work/docker  
  13. ExecReload=/bin/kill -s HUP $MAINPID
  14. # Having non-zero Limit*s causes performance problems due to accounting overhead
  15. # in the kernel. We recommend using cgroups to do container-local accounting.
  16. LimitNOFILE=infinity
  17. LimitNPROC=infinity
  18. LimitCORE=infinity
  19. # Uncomment TasksMax if your systemd version supports it.
  20. # Only systemd 226 and above support this version.
  21. #TasksMax=infinity
  22. TimeoutStartSec=0
  23. # set delegate yes so that systemd does not reset the cgroups of docker containers
  24. Delegate=yes
  25. # kill only the docker process, not all processes in the cgroup
  26. KillMode=process
  27. # restart the docker process if it exits prematurely
  28. Restart=on-failure
  29. StartLimitBurst=3
  30. StartLimitInterval=60s
  32. [Install]
  33. WantedBy=multi-user.target

  1. 准备好daemon.json文件

    1. {
    2. "log-driver":"json-file",
    3. "log-opts": {"max-size":"500m", "max-file":"3"}
    4. }

  2. 使用tar命令解压，将docker/*所有文件复制或剪切到/usr/bin目录下

  3. 将我们准备好的docker.service复制到/etc/systemd/system目录下（docker.service记得赋执行权限 chmod +x docker.service）
  4. 将我们准备好的daemon.json文件复制或剪切到/etc/docker目录下去，没有此目录就自行创建
  5. 启动docker
    • systemctl daemon-reload： 启动守护进程
    • systemctl start docker： 启动docker
    • systemctl enable docker.service： 开启开机自启动
    • systemctl status docker ：验证
