一、基础环境

1、操作系统：CentOS 7.3

2、Docker版本：18.06.1

二、Docker安装

1、解压

tar -xvf docker-18.06.1-ce.tgz

2、将解压出来的docker文件内容移动到 /usr/bin/ 目录下

cp docker/* /usr/bin/

3、将docker注册为service

vim /etc/systemd/system/docker.service

将下列配置加到docker.service中并保存。

[Unit]Description=Docker Application Container EngineDocumentation=https://docs.docker.comAfter=network-online.target firewalld.serviceWants=network-online.target[Service]Type=notify# the default is not to use systemd for cgroups because the delegate issues still# exists and systemd currently does not support the cgroup feature set required# for containers run by dockerExecStart=/usr/bin/dockerdExecReload=/bin/kill -s HUP $MAINPID# Having non-zero Limit*s causes performance problems due to accounting overhead# in the kernel. We recommend using cgroups to do container-local accounting.LimitNOFILE=infinityLimitNPROC=infinityLimitCORE=infinity# Uncomment TasksMax if your systemd version supports it.# Only systemd 226 and above support this version.#TasksMax=infinityTimeoutStartSec=0# set delegate yes so that systemd does not reset the cgroups of docker containersDelegate=yes# kill only the docker process, not all processes in the cgroupKillMode=process# restart the docker process if it exits prematurelyRestart=on-failureStartLimitBurst=3StartLimitInterval=60s [Install]WantedBy=multi-user.target

4、启动

chmod +x /etc/systemd/system/docker.service    #添加文件权限并启动dockersystemctl daemon-reload    #重载unit配置文件systemctl start docker    #启动Dockersystemctl enable docker.service  #设置开机自启

5、验证

systemctl status docker   #查看Docker状态docker -v   #查看Docker版本
