1.docker rpm包下載地址
# https://download.docker.com/linux/centos/7/x86_64/stable/Packages/
2.下載rpm包
# wget https://download.docker.com/linux/centos/7/x86_64/stable/Packages/docker-ce-18.06.0.ce-3.el7.x86_64.rpm
3.安裝docker
# 下載阿里的docker-ce源
# cd /etc/yum.repos.d/ && wget https://mirrors.aliyun.com/docker-ce/linux/centos/docker-ce.repo
# yum -y install docker-ce-18.06.0.ce-3.el7.x86_64.rpm
4.鏡像加速配置
# mkdir -p /etc/docker/
# cat >/etc/docker/daemon.json<<EOF { "registry-mirrors": ["https://registry.docker-cn.com"] } EOF
5.指定docker目錄啟動
# vim /usr/lib/systemd/system/docker.service [Unit] Description=Docker Application Container Engine Documentation=https://docs.docker.com BindsTo=containerd.service After=network-online.target firewalld.service containerd.service Wants=network-online.target Requires=docker.socket [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 --graph /home/meisoo/docker --insecure-registry=172.17.29.74 -H fd:// --containerd=/run/containerd/containerd.sock ExecReload=/bin/kill -s HUP $MAINPID TimeoutSec=0 RestartSec=2 Restart=always # Note that StartLimit* options were moved from "Service" to "Unit" in systemd 229. # Both the old, and new location are accepted by systemd 229 and up, so using the old location # to make them work for either version of systemd. StartLimitBurst=3 # Note that StartLimitInterval was renamed to StartLimitIntervalSec in systemd 230. # Both the old, and new name are accepted by systemd 230 and up, so using the old name to make # this option work for either version of systemd.

6.啟動docker
systemctl start docker.service
