虚拟机 CentOs 7 离线安装 Docker

Docker 下载网址：

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

1.在usr下的local中新建名称为docker的文件夹

cd /usr/local/

mkdir docker

2.进入/usr/local/docker目录，上传docker压缩文件

cd docker

解压执行：

tar -zxvf docker-18.06.3-ce.tgz

 

3.将解压出来的docker文件复制到/usr/bin/目录下

cp docker/* /usr/bin/

4.进入/etc/systemd/system/目录，并创建docker.service文件

cd /etc/systemd/system/

touch docker.service

5.打开docker.service文件，

vim docker.service

将以下内容复制进去

注意：ip地址改为自己的（ExecStart=/usr/bin/dockerd --selinux-enabled=false --insecure-registry=192.168.94.110）

 # 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

 # Only systemd 226 and above support this version.
 #TasksMax=infinity

 [Install]
 WantedBy=multi-user.target

6.给docker.service文件添加执行权限

chmod 777 /etc/systemd/system/docker.service

7.重启使配置生效

systemctl daemon-reload

8.启动docker

systemctl start docker

9.查看docker状态

systemctl status docker

出现这个页面就表示成功了

10.打开docker配置文件，配置国内镜像加速器

vim /etc/docker/daemon.json

配置如下：

{
   "registry-mirrors": ["https://ky3rtfiy.mirror.aliyuncs.com"]
 }

重启使配置生效

systemctl daemon-reload

11.重启docker

systemctl restart docker
