一、项目环境
公司在实际的生产环境中，需要使用 Docker 技术在一台主机上创建 LNMP 服务并运行 Wordpress 网站平台。然后对此服务进行相关的性能调优和管理工作。
1.1 所有安装包下载：
wget http://101.34.22.188/lnmp_wordpress/mysql-boost-5.7.20.tar.gz
wget http://101.34.22.188/lnmp_wordpress/nginx-1.12.0.tar.gz
wget http://101.34.22.188/lnmp_wordpress/php-7.1.10.tar.bz2
wget http://101.34.22.188/lnmp_wordpress/wordpress-4.9.4-zh_CN.tar.gz
或者
wget -r -np http://101.34.22.188/lnmp_wordpress/
1.3 服务器环境
| 容器 | 操作系统 | IP地址 | 主要软件 |
| nginx | CentOS 7 | 192.168.237.21 | Docker-Nginx |
| mysql | CentOS 7 | 192.168.237.22 | Docker-Mysql |
| PHP | CentOS 7 | 192.168.237.23 | Docker-php |
1.4任务需求
- 使用 Docker 构建 LNMP 环境并运行 Wordpress 网站平台
- 限制 Nginx 容器最多使用 500MB 的内存和 1G 的 Swap
- 限制 Mysql 容器写 /dev/sda 的速率为 10 MB/s
- 将所有容器进行快照，然后将 Docker 镜像打包成 tar 包备份到本地
二、Ngin
2.1、建立工作目录
[root@docker ~]# mkdir /opt/nginx
[root@docker ~]# cd /opt/nginx
#上传 nginx 安装包 nginx-1.12.0.tar.gz
#上传 wordpress 服务包 wordpress-4.9.4-zh_CN.tar.gz
2.2 编写 Dockerfile 脚本
[root@docker nginx]# vim Dockerfile
