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:alpine
		ports:
		- 80:80
		volumes:
		- /root/html:/usr/shara/nginx/html
		- /root/conf/nginx.conf:/etc/nginx/nginx.conf
	php:
		image: devilbox/php-fpm:5.2-work-0.89
		volumes:
		- /root/html:/var/www/html
	mysql:
		image: mysql:5.6
		environment:
		-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。
