docker-compose实战~如何组织一个多容器项目堆

先启动一台nginx查看ip：

下面开启一台alpine并安装curl测试连通性：

–link

以上测试还可以换一种方式–link

docker-compose

首先创建两个目录：

conf存放nginx的配置文件(图片错了，后面改成conf目录了)

html存放html文件和php文件

<?php
Sdbhost = 'localhost';
Sdbuser = 'root';
$dbpass = '123456':
$conn = mysql_connect (Sdbhost,Sdbuser,Sdbpass);
if(!$conn)
{die('Could not connet:'.mysgli error（）);echo 'mysql connected!!mysqli close ($conn);
}
?>

然后就是配置文件：

version: "3"
services:nginx:image: nginx:alpineports:- 80:80volumes:- /root/html:/usr/shara/nginx/html- /root/conf/nginx.conf:/etc/nginx/nginx.confphp:image: devilbox/php-fpm:5.2-work-0.89volumes:- /root/html:/var/www/htmlmysql:image: mysql:5.6environment:-MYSQL_ROOT_PASSWORD=123456

---

worker_processes 1;
events {worker_connections 1024;}
http {include	mime.types;default_type application/octet-stream;sendfile on;keepalive_timeout 65;server {listen 80;server_name localhost;location / {root /usr/shara/nginx/html;index index.html index.htm;}error_pase 500 502 503 504 /50x.html;location = /50x.html {root /usr/shara/nginx/html;}location ~ \.php$ {fastcgi_pass php:9000;fastcgi_index index.php;fastcgi_param SCRIPT_FILENAME /var/www/html/$fastcgi_script_name;include fastcgi_params;}}
}

访问流程：

结果就是访问80端口，默认显示index.html。访问phpinfo.php显示信息。访问mysql.php连接成功数据库。
