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

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,检验

# ps aux|grep docker

root 2266 0.2 1.3 277032 13540 ? Ssl 16:38 0:01 docker-containerd --config /var/run/docker/containerd/containerd.toml

# docker run hello-world

Hello from Docker!

This message shows that your installation appears to be working correctly.

To generate this message, Docker took the following steps:

1. The Docker client contacted the Docker daemon.

2. The Docker daemon pulled the "hello-world" image from the Docker Hub.

(amd64)

3. The Docker daemon created a new container from that image which runs the

executable that produces the output you are currently reading.

4. The Docker daemon streamed that output to the Docker client, which sent it

to your terminal.

To try something more ambitious, you can run an Ubuntu container with:

$ docker run -it ubuntu bash
