源码安装docker

1.下载docker源码

wget https://mirrors.tuna.tsinghua.edu.cn/docker-ce/linux/static/stable/x86_64/docker-18.09.0.tgz

2.将解压出来的docker目录下的指令复制到 /usr/bin/ 目录下

tar xf docker-18.09.0.tgz cp docker/* /usr/bin/　

3.将docker注册为service服务 新建该文件

vi /etc/systemd/system/docker.service

加入以下内容：

[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 -g /opt/docker ExecReload=/bin/kill -s HUP $MAINPID LimitNOFILE=infinity LimitNPROC=infinity LimitCORE=infinity TimeoutStartSec=0 Delegate=yes KillMode=process Restart=on-failure StartLimitBurst=3 StartLimitInterval=60s [Install] WantedBy=multi-user.target

ExecStart=/usr/bin/dockerd -g /opt/docker #启动docker操作并指定数据目录 4.添加执行权限并重新加载配置文件

chmod a+x /etc/systemd/system/docker.service systemctl daemon-reload systemctl restart docker

验证 docker --version
