1,下載二進制文件
https://download.docker.com/linux/static/stable/x86_64/docker-18.03.1-ce.tgz
2,解壓二進制文件
tar xzvf docker-18.03.1-ce.tgz
3,復制二進制文件到/usr/bin目錄下
cp docker/* /usr/bin/
4,檢查是否安裝
docker version
Client:
Version: 18.03.1-ce
API version: 1.37
Go version: go1.9.2
Git commit: 9ee9f40

Engine:

5,配置 docker.service文件
vi /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
6,啟動dockerd服務進程
systemctl daemon-reload
systemctl start docker.service
7.拉取鏡像
docker pull centos:centos7
如果拉取鏡像報錯
錯誤信息:Get https://registry-1.docker.io/v2/: net/http: request canceled while waiting for connection (Client.Timeout exceeded while awaiting headers)
因為默認鏡像源是國外的，速度比較慢，就會導致超時報錯
所以換成國內的鏡像源來加速
vim /etc/docker/daemon.json(新增網易鏡像)
{"registry-mirrors":["http://hub-mirror.c.163.com"] }
重新加載配置文件
systemctl daemon-reload
重啟docker
systemctl restart docker
