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
