2020系统综合实验 第2次实践作业

（1） 实现一个自定义的web容器服务

---------------------------------------准备工作------------------------------------------

1、创建mynginx目录并进入目录创建Dockerfile文件

2、获取配置文件内容

　　2.1由于我之前已经拉过nginx和mysql的镜像，所以它们直接在本地

             2.2运行nginx容器

             2.3进入容器

 　   　   2.4获取配置文件default.conf的内容

             2.5将端口号改为4399和root路径改为自己的本地文件路径并保存

 　　      2.6创建一个简易的html文件（index.html）

 3、编写Dockerfile文件

------------------------------------------------------开始正式构建----------------------------------------------------------

 4、构建nginx镜像

　　docker build -t mynginx：v1  .

 

 5、运行一个容器

　　$ docker run --name my_nginx -p 8080:4399 -d nginx

---------------------------------------------------------------验证结果---------------------------------------------------------------

---

（2） 实现一个自定义的数据库容器服务

1、创建自定义的存放目录mymysql

2、进入目录创建Dockerfile文件

3、编写Dockerfile文件

3.1setup.sh

 3.2data.sql

 3.3privileges.sql

4、构建mysql镜像

　　docker build -t mysql：v1  .

 4.1执行docker images查看镜像

 4.2启动容器

 5、查看配置信息

6、进入mysql，验证信息

 6.1查看内容

　　小结：又是忙忙碌碌的一周实验，主要知道了如何利用Dockfile自定义镜像，中间也碰到过类似于系统文件已满（/dev/sda1）无法写入的问题，由于忘记截屏，所以没有展示。我就去追踪文件然后删除了一些缓存和日志文件。还有就是后面的MYSQL镜像制作那块要用到Mysql的语句知识，当时学的也忘得差不多了，就当是又看了一遍。
