1.首先，升级软件包
sudo apt-get update
sudo apt-get upgrade

2.安装nginx
sudo apt-get install nginx
在浏览器输入服务器ip测试nginx是否安装成功

3.安装数据库
sudo apt-get install mysql-server php5-mysql
输入mysql -u root -p 测试数据库是否安装成功

4.安装php-fpm
PHP-FPM是一个PHPFastCGI管理器，是只用于PHP的。使用PHP-FPM来控制PHP-CGI的FastCGI进程
sudo apt-get install php5-fpm
（1）配置php-fpm
sudo vi /etc/php5/fpm/php.ini
将 cgi.fix_pathinfo=1 改为 cgi.fix_pathinfo=0
（2）sudo service php5-fpm restart

5.解决nginx打开php文件总是显示下载框的问题
sudo vi /etc/nginx/sites-available/default

将
location ~ .php$ {

# With php5-cgi alone:

fastcgi_pass 127.0.0.1:9000;

# With php5-fpm:

fastcgi_pass unix:/var/run/php5-fpm.sock;

fastcgi_index index.php;

include fastcgi_params;

}
改为
location ~ .php$ {
fastcgi_split_path_info ^(.+.php)(/.+)$;

# With php5-cgi alone:

fastcgi_pass 127.0.0.1:9000;

# With php5-fpm:

     fastcgi_pass unix:/var/run/php5-fpm.sock;
     fastcgi_index index.php;
     include fastcgi_params;

}
最后，记得重启nginx服务器！

sudo service nginx restart

6.测试nginx是否解析PHP
cd /usr/share/nginx/html
vim index.php
输入
