Docker学习笔记一.Docker离线安装与自启动

 

1. 下载对应二进制包 

官网手动下载地址：https://download.docker.com/linux/static/stable/x86_64/

或：

wget https://download.docker.com/linux/static/stable/x86_64/docker-20.10.2.tgz

2. 解压后并复制到/usr/bin目录下

tar zxvf docker-20.10.2.tgz 

cp  docker/* /usr/bin/  

3. 添加docker.service文件

vi /etc/systemd/system/docker.service

LimitNOFILE=infinity
LimitNPROC=infinity

KillMode=process
Restart=on-failure
StartLimitBurst=3
StartLimitInterval=60s 

[Install]
WantedBy=multi-user.target 

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

4. 添加 docker.socket 文件

vi /lib/systemd/system/docker.socket 

[Unit]

  "insecure-registries": ["xxx.xxx.xxx.xxx:5000"],
  "data-root": "/data/docker"
}

 

6. 启动docker服务并设置开机自启

systemctl daemon-reload
systemctl start docker
systemctl enable docker.service
