一.在线安装

1.安装依赖

yum install -y yum-utils device-mapper-persistent-data lvm2

2.添加软件源

yum-config-manager --add-repo http://mirrors.aliyun.com/docker-ce/linux/centos/docker-ce.repo

3.安装docker-ce

yum  -y install docker-ce

4.启动服务

systemctl start docker

5.查看docker版本信息

docker version

二.离线安装

1.登录镜像网站

https://download.docker.com/linux/static/stable/x86_64/

2.解压

tar -xvf docker-18.06.1-ce.tgz

3.把解压出来的文件移动到/usr/bin 目录下

cp docker/* /usr/bin/

4.将docker注册为service

vim /etc/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
    # 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 docker
    ExecStart=/usr/bin/dockerd
    ExecReload=/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=infinity
    LimitNPROC=infinity
    LimitCORE=infinity
    # Uncomment TasksMax if your systemd version supports it.
    # Only systemd 226 and above support this version.
    #TasksMax=infinity
    TimeoutStartSec=0
    # set delegate yes so that systemd does not reset the cgroups of docker containers
    Delegate=yes
    # kill only the docker process, not all processes in the cgroup
    KillMode=process
    # restart the docker process if it exits prematurely
    Restart=on-failure
    StartLimitBurst=3
    StartLimitInterval=60s
     
    [Install]
    WantedBy=multi-user.target

5.启动

chmod +x /etc/systemd/system/docker.service
    systemctl daemon-reload
    systemctl start docker            
    systemctl enable docker.service
