Dockerfile运用(容器LNMP架构+wordpress)
环境准备
systemctl stop firewalld
setenforce 0
#创建自定义网络，方便自定义容器网段
docker network create --subnet=172.18.0.0/16 --opt "com.docker.network.bridge.name"="docker1" mynetwork
Nginx容器（容器ip和端口为172.18.0.10:80）

mkdir /opt/nginx/html tar zxvf wordpress-4.9.4-zh_CN.tar.gz -C /opt/nginx/html #另外的主机使用源码编译安装nginx将起conf目录内所有文件传入到容器宿主机，方便挂载给nginx容器使用 vim Dockerfile FROM centos:7 MAINTAINER this is nginx image <dd>

php容器（容器ip和端口为172.18.0.30:9000）
mkdir /opt/php
cd /opt/php
#上传 php-7.1.10.tar.bz2到 /opt/php 目录中
#在另一台主机上安装php，在/opt/php 目录中提前配置好三个文件，直接复制给容器
php.ini 主配置文件
php-fpm.conf 进程服务配置文件
www.conf 扩展配置文件（优化用的）
