1、LNMP架构
搭建一个lnmp环境，需要涉及到两个目录结构。一个是Dockerfile配置的目录结构，另一个是最终lnmp运行的目录结构。Dockerfile配置目录主要存放Dockerfile构建脚本和一些配置文件，lnmp运行目录主要存放程序运行产生的一些数据，比如mysql数据等。
以下是此次Dockerfile配置的目录结构，包括了nginx、php、mysql的配置文件。
[root@docker /opt]# ll mysqld/
总用量 47704
-rw-r--r-- 1 root root 1224 11月 13 23:34 Dockerfile
-rw-r--r-- 1 root root 556 11月 13 23:35 my.cnf
-rw-r--r-- 1 root root 48833145 11月 13 23:33 mysql-boost-5.7.20.tar.gz
-rw-r--r-- 1 root root 171 11月 13 23:36 run.sh
[root@docker /opt]# ll nginx/
总用量 9840
-rw-r--r-- 1 root root 627 11月 13 23:18 Dockerfile
-rw-r--r-- 1 root root 981687 11月 13 23:14 nginx-1.12.2.tar.gz
-rw-r--r-- 1 root root 791 11月 13 23:20 nginx.conf
-rw-r--r-- 1 root root 9082696 11月 13 23:15 wordpress-4.9.4-zh_CN.tar.gz
[root@docker /opt]# ll php/
总用量 19096
-rw-r--r-- 1 root root 963 11月 13 23:52 Dockerfile
drwxrwxr-x 15 1000 1000 4096 9月 27 2017 php-7.1.10
-rw-r--r-- 1 root root 19440059 11月 14 00:19 php-7.1.10.tar.gz
-rw-r--r-- 1 root root 4462 11月 14 00:39 php-fpm.conf
-rw-r--r-- 1 root root 71122 11月 14 00:20 php.ini
-rw-r--r-- 1 root root 18524 11月 14 00:38 www.conf
二、所需安装包下载
php：
https://www.php.net/distributions/php-7.1.10.tar.bz2
nginx：
http://nginx.org/download/nginx-1.12.2.tar.gz
wordpress：
https://cn.wordpress.org/wordpress-4.9.4-zh_CN.tar.gz
mysql：
https://downloads.mysql.com/archives/get/p/23/file/mysql-boost-5.7.20.tar.gz
任务需求：
（1）、使用 Docker 构建 LNMP 环境并运行 Wordpress 网站平台
（2）、限制 Nginx 容器最多使用 500MB 的内存和 1G 的 Swap
（3）、限制 Mysql 容器写 /dev/sda 的速率为 10 MB/s
（4）、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
三、Dockerfile部署LNMP
先自定义网络，再使用指定IP运行docker
是LNMP各组件处于同一网段
[root@docker ~]# docker network create --subnet=172.20.0.0/16 --opt "com.docker.network.bridge.name"="docker1" mynetwork
f711d688445880c66844ec60a88dda3a63065544fc9782a7f00c29b555f47c50
[root@docker ~]# docker network ls

[root@docker ~]# ifconfig

| 容器 | 操作系统 | IP | 软件 |
| Nginx | centos7 | 172.20.0.10 | Docker-Nginx |
| MySQL | centos7 | 172.20.0.20 | Docker-Mysql |
| PHP | centos7 | 172.20.0.30 | Docker-php |
3.1、构建Nginx镜像
（1）、创建nginx的工作目录
[root@docker ~]# mkdir /opt/nginx
[root@docker ~]# cd /opt/nginx/
[root@docker /opt/nginx]# （2）、编辑Dockerfile配置文件
cat Dockerfile
FROM centos:7

ENV PATH /usr/local/nginx/sbin:$PATH

RUN chmod 777 -R /usr/local/nginx/html/
EXPOSE 80
VOLUME [ "/usr/local/nginx/html/" ]
CMD [ "/usr/local/nginx/sbin/nginx","-g","daemon off;" ]（3）、准备nginx配置文件
cat nginx.conf
worker_processes 1;

worker_connections 1024;
}
http {
include mime.types;
default_type application/octet-stream;
sendfile on;
keepalive_timeout 65;

location / {

index index.html index.php;
}
error_page 500 502 503 504 /50x.html;
location = /50x.html {

}
location ~ \.php$ {

fastcgi_index index.php;
fastcgi_param SCRIPT_FILENAME /usr/local/nginx/html$fastcgi_script_name;
include fastcgi_params;
}
}
}（4）、构建nginx镜像
