目前项目以部署了一套java web环境，但后来想在work.域名.com部署一套PHP 工作流系统

一.前言

在阿里云域名设置二级域名

部署号java 环境（tomcat MysqL java sdk）,[若不熟悉可见jdk tomcat mysql安装]

然后www.域名.com,访问成功

二.安装PHP

sudo apt-get install PHP5 libapache2-mod-PHP5
sudo /etc/init.d/apache2 restart(重启apache)

三.安装apache2

1.输入命令：sudo apt-get install apache2即可安装，

安装完后，打开浏览器，在地址栏输入：localhost或者http://127.0.0.1
看到It works，表示安装成功！
默认根目录：/var/www/

2.让apache和PHP支持PHP ：

sudo apt-get install libapache2-mod-auth-MysqL
sudo apt-get install PHP5-MysqL
sudo /etc/init.d/apache2 restart(重启apache)

3.然后在/var/www/ 下新建test.PHP,如下内容上传后，访问，会提示成功

<?PHP 
echo "PHP 程序.....start MysqL connect..."; 
try{      
  
#$link=MysqL_connect("120.26.130.20","root","1314159"); 
$link=MysqL_connect("127.0.0.1","1314159"); 
if(!$link) echo "FAILD!连接错误，用户名密码不对"; 
else echo "OK!可以连接"; 
}catch(PDOException $e){  
    echo "error".$e->getMessage()."</br>";  
    die();  
}  

?> 

在ports.conf 设置Listen 8081，并sites-available/000-defaut.conf设置<VirtualHost *:8081>

并将 tomcat 设置8080;

四.安装Nginx

1. apt-get install Nginx

2.访问 会 提示Nginx 成功

3./etc/Nginx/sites-available/default替换server 节点

server {  
    listen       80;  
    server_name  域名.com;  
    location / {  
        proxy_pass http://localhost:8080/;  
        proxy_set_header   Host    $host;  
        proxy_set_header   X-Real-IP   $remote_addr;  
        proxy_set_header   X-Forwarded-For $proxy_add_x_forwarded_for;  
    }  
}server {  
    listen       80;  
    server_name  www.域名.com;  
    location / {  
       proxy_pass http://localhost:8080/;  
        proxy_set_header   Host    $host;  
        proxy_set_header   X-Real-IP   $remote_addr;  
        proxy_set_header   X-Forwarded-For $proxy_add_x_forwarded_for;  
    }  
}  
server {  
    listen       80;  
    server_name  work.域名.com;  
    location / {  
        proxy_pass http://localhost:8081/;  
        proxy_set_header   Host    $host;  
        proxy_set_header   X-Real-IP   $remote_addr;  
        proxy_set_header   X-Forwarded-For $proxy_add_x_forwarded_for;  
    }  
}  
server {  
    listen       80;  
    server_name  www.work.域名.com;  
    location / {  
        proxy_pass http://localhost:8081/;  
        proxy_set_header   Host    $host;  
        proxy_set_header   X-Real-IP   $remote_addr;  
        proxy_set_header   X-Forwarded-For $proxy_add_x_forwarded_for;  
    }  
}  

1.service Nginx status

etc/init.d/MysqLd start

sudo /etc/init.d/apache2 restart

2.手把手教你在ubuntu上安装apache和mysql和php
