部署Linux内网docker实践过程

1. 查看Linux内核版本的命令

   cat /proc/version

   下载docker静态二进制存档
    要根据硬件平台下载以免造成不兼容

   https://download.docker.com/

   https://download.docker.com/linux/static/stable/x86_64/docker-20.10.7.tgz 

   本文中演示下载版本为x86 docker-20.10.7.tgz  

   2 将下载好的文件上传到服务器

   
    解压 tar -zxvf docker-20.10.7.tgz 

   3 将二进制文件移到可执行文件目录下 
    

   4 配置docker.service  
    vim /usr/lib/systemd/system/docker.service

   [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 启动dockerd服务 
   [root@localhost opt]# systemctl daemon-reload
   [root@localhost opt]# systemctl start docker.service
   [root@localhost opt]# docker info
    

   将docker设置为开机自启动

   systemctl enable docker
