源碼安裝docker

1.下載docker源碼

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

2.將解壓出來的docker目錄下的指令複製到 /usr/bin/ 目錄下

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

3.將docker註冊爲service服務
新建該文件

vi /etc/systemd/system/docker.service

加入以下內容：

[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   #指定數據目錄
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

4.添加執行權限並重新加載配置文件

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

驗證
docker --version
