1. 下载Docker安装包
下载地址：https://download.docker.com/linux/static/stable/x86_64/
如果服务器可以联网可以通过wget下载安装包
wget https://download.docker.com/linux/static/stable/x86_64/docker-18.06.3-ce.tgz
2. 解压安装
tar -zxvf docker-18.06.3-ce.tgz
然后把解压出来的docker文件复制到/usr/bin目录下
cp docker/* /usr/bin/
3. 增加Docker配置文件
1. 新建docker.serivce文件
在/etc/systemd/system/目录新建docker.service文件
vim /etc/systemd/system/docker.service
2. 写入配置文件
文件内容如下：
[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 --selinux-enabled=false --insecure-registry=127.0.0.1
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
3. 修改Hardor的IP
这里要修改-insecure-registry=127.0.0.1 。此处的ip为当前Docker Harbor私服的IP。
4. 赋予配置文件权限
然后给docker.service赋予权限
4. 启动Docker
systemctl daemon-reload
systemctl start docker
设置开机启动
systemctl enable docker.service
查看docker状态
systemctl status docker
