实战~如何组织一个多容器项目docker-compose

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。
