Linux离线环境安装部署docker(超详细)

离线文件下载:根据实际情况下载离线包

docker-Linux下载地址

搭建Docker环境准备

在能连网的服务器上下载所需的镜像,例如

docker pull Mysql:8(拉取mysql:8镜像)docker images(查看镜像)docker save -o mysql-8.tar mysql:8 (将mysql:8镜像压缩成mysql-8.tar压缩包文件)

上传docker压缩包及镜像上传到需要部署的服务器上,然后进行解压,例如:

1. 解压docker软件压缩包

tar -zxvf docker-20.10.9.tgz 

2. 把docker文件里面的内容复制到bin目录下

cp docker/* /usr/bin

3. 在/etc/systemd/system或者/usr/lib/systemd/system目录下创建文件 docker.Socket和docker.service以及containerd.service

三个文件的内容放最后面,记得先把文件内容加上才能启动docker哦

touch docker.socketouch docker.servicetouch containerd.service

4. 重新加载配置文件

systemctl daemon-reload 

5. 创建组

groupadd docker

6. 启动docker

systemctl start docker

7. 查看dock是否启动成功:运行命令没报错就没问题了

docker ps 

8. 设置开机自启动

systemctl enable docker.service

9. 导入镜像

docker load -i mysql.tar

10. 查看镜像

docker images

11. 根据实际情况构建容器,例如:

docker run -itd --name mysql-test -p 3306:3306 -e MYSQL_ROOT_PASSWord=123456 mysql:8
