Docker之使用Docker-compose搭建LNMP环境

　　之前有随笔介绍使用Docker-compose搭建LNMP环境（centos6 php5.6）

https://www.cnblogs.com/minseo/p/10146982.html

　　本文介绍Docker-compose搭建LNMP环境(centos7 php7)

　　文件目录结构如下

├── docker-compose.yml
├── mysql
│   ├── conf
│   └── data
├── nginx
│   ├── Dockerfile
│   ├── nginx-1.16.0.tar.gz
│   └── nginx.conf
├── php
│   ├── Dockerfile
│   ├── libzip-1.2.0.tar.gz
│   ├── php-7.3.9.tar.gz
│   └── php.ini
└── wwwroot
    ├── index.html
    └── test.php

　　需下载安装包 nginx-1.16.0.tar.gz libzip-1.2.0.tar.gz php-7.3.9.tar.gz

wget http://nginx.org/download/nginx-1.16.1.tar.gz
wget https://libzip.org/download/libzip-1.2.0.tar.gz
wget https://www.php.net/distributions/php-7.3.9.tar.gz

　　docker-compose.yml

version: '3'
services:
  nginx:
    hostname: nginx
    build:
      context: ./nginx
      dockerfile: Dockerfile
    ports:
      - "80:80"
    links:
      - php:php-cgi
    volumes:
      - ./wwwroot:/usr/local/nginx/html

  php:
    hostname: php
    build: ./php
    links:
      - mysql:mysql-db
    volumes:
      - ./wwwroot:/usr/local/nginx/html

  mysql:
    hostname: mysql
    image: mysql:5.7
    ports:
      - "3306:3306"
    volumes:
      - ./mysql/conf:/etc/mysql/conf.d
      - ./mysql/data:/var/lib/mysql
    environment:
      MYSQL_ROOT_PASSWORD: 123456
      MYSQL_DATABASE: wordpress
      MYSQL_USER: user
      MYSQL_PASSWORD: user123

　　PS:links php:php-cgi意思是链接到服务名为php的服务，可以使用host名 php-cgi访问该容器，在启动容器后进入容器ping

　　进入nginx容器ping测试

　　同理下面的配置mysql:mysql-db也是一样的道理，在php容器中使用host名mysql-db访问mysql容器

　　PS：1，CentOS7自带libzip版本较低需要下载编译安装

　　  　　2，需要把默认配置文件www.conf.default重命名为www.conf并且修改配置把127.0.0.1改成0.0.0.0否则会导致无法访问php页面，因为启动了不同的容器无法通过127.0.0.1访问

3，配置文件php.ini可以不拷贝

　　wwwroot/test.php

<?php phpinfo()?>

　　启动

docker-compose up -d

　　查看

　　web页面访问
