本篇文章重点为大家讲解一下Linux下使用二进制文件的方式安装docker具体步骤，有需要的小伙伴可以参考一下。
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 Built: Thu Apr 26 07:12:25 2018 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 Built: Thu Apr 26 07:23:03 2018 OS/Arch: linux/amd64 Experimental: false 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 2262 0.1 4.4 472948 44944 ? Ssl 16:38 0:00 /usr/bin/dockerd root 2266 0.2 1.3 277032 13540 ? Ssl 16:38 0:01 docker-containerd --config /var/run/docker/containerd/containerd.toml root 2895 0.0 0.0 112660 972 pts/0 S+ 16:48 0:00 grep --color=auto docker # 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 Share images, automate workflows, and more with a free Docker ID: https://hub.docker.com/ For more examples and ideas, visit: https://docs.docker.com/engine/userguide/
