linux下通过二进制文件安装docker

1,下载二进制文件

https://download.docker.com/linux/static/stable/x86_64/docker-18.03.1-ce.tgz
2,解压二进制文件

tar xzvf docker-18.03.1-ce.tgz
3,复制二进制文件到/usr/bin目录下

cp docker/* /usr/bin/
4,检查是否安装

docker version
Client:
Version:      18.03.1-ce
API version:  1.37
Go version:   go1.9.2
Git commit:   9ee9f40

OS/Arch:      linux/amd64
Experimental: false
Orchestrator: swarm

Server:
Engine:
Version:      18.03.1-ce
API version:  1.37 (minimum version 1.12)
Go version:   go1.9.5
Git commit:   9ee9f40

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,启动dockerd服务进程

systemctl daemon-reload
systemctl start docker.service

 7.拉取镜像

docker pull centos:centos7

如果拉取镜像报错

错误信息:Get https://registry-1.docker.io/v2/: net/http: request canceled while waiting for connection (Client.Timeout exceeded while awaiting headers)
因为默认镜像源是国外的，速度比较慢，就会导致超时报错

所以换成国内的镜像源来加速

vim /etc/docker/daemon.json(新增网易镜像)

{"registry-mirrors":["http://hub-mirror.c.163.com"] }

重新加载配置文件

systemctl daemon-reload

重启docker

systemctl restart docker
