二進制包安裝docker

docker下載地址

https://download.docker.com/linux/static/stable/x86_64/

 

下載安裝

wget https://download.docker.com/linux/static/stable/x86_64/docker-19.03.6.tgz
tar -zvxf docker-19.03.6.tgz
cp docker/* /usr/bin/

 

直接運行

/usr/bin/dockerd

 

demon模式運行,並保存日志

nohup /usr/bin/dockerd >/docker.log 2>&1 &

 

systemctl運行

sudo vim /etc/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

 

設置權限權限為可執行

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

 

常用命令

systemctl daemon-reload   //重載配置文件
systemctl start docker    //啟動Docker
systemctl stop docker    //關閉docker
systemctl restart  docker    //重啟docker
systemctl enable docker.service   //設置開機自啟
systemctl status docker    //查看Docker狀態

 

很多時候在我們掛載磁盤后不想用docker默認目錄 可 -g 修改目錄 （docker 默認目錄在/var/lib/docker下，包括 pull下來的鏡像都在該目錄下）

ExecStart修改為:

ExecStart=/usr/bin/dockerd -g /xiaobo/docker

 

修改后啟動docker，路徑已修改成功
