一般我们都是采用 Apache 作为 PHP 的解析服务器，这次则是采用 Nginx 这个强大的反向代理服务器来搭建 PHP 服务器。下面就以 Linux 发行版 Ubuntu 为例搭建一个 Nginx 的 PHP 服务器。

首先下载安装 Nginx
sudo apt-get install nginx

安装完成后，启动 Nginx
sudo /etc/init.d/nginx start

这时候打开浏览器里输入 http://localhost/ 就可以看到 Welcome to nginx! 的页面了，说明我们的 Nginx 服务器安装成功

接下来安装 PHP5
sudo apt-get install php5-fpm

安装成功后，我们要修改 Nginx 的虚拟机配置，让浏览器请求的 php 文件可以被 php cgi 解析。编辑 Nginx 虚拟机配置文件 /etc/nginx/sites-available/default
sudo vim /etc/nginx/sites-available/default

然后把里面的配置修改为如下配置内容：
# You may add here your
# server {
# …
# }
# statements for each of your virtual hosts to this file

##
# You should look at the following URL’s in order to grasp a solid understanding
# of Nginx configuration files in order to fully unleash the power of Nginx.
# http://wiki.nginx.org/Pitfalls
# http://wiki.nginx.org/QuickStart
# http://wiki.nginx.org/Configuration
#
# Generally, you will want to move this file somewhere, and start with a clean
# file but keep this around for reference. Or just disable in sites-enabled.
#
# Please see /usr/share/doc/nginx-doc/examples/ for more detailed examples.

server {
listen 80; ## listen for ipv4; this line is default and implied
#listen [::]:80 default ipv6only=on; ## listen for ipv6

root /usr/share/nginx/www;
index index.html index.htm index.php;

# Make site accessible from http://localhost/
server_name localhost;

location / {
# First attempt to serve request as file, then
# as directory, then fall back to index.html
try_files $uri $uri/ /index.html;
# Uncomment to enable naxsi on this location
# include /etc/nginx/naxsi.rules
}

location /doc/ {
alias /usr/share/doc/;
autoindex on;
allow 127.0.0.1;
deny all;
}

# Only for nginx-naxsi : process denied requests
#location /RequestDenied {
# For example, return an error code
#return 418;
# }

error_page 404 /404.html;

# redirect server error pages to the static page /50x.html
#
error_page 500 502 503 504 /50x.html;
location = /50x.html {
root /usr/share/nginx/www;
}

# pass the PHP scripts to FastCGI server listening on 127.0.0.1:9000
#
location ~ \.php$ {
fastcgi_split_path_info ^(.+\.php)(/.+)$;
# NOTE: You should have “cgi.fix_pathinfo = 0;” in php.ini

# 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;
}

# deny access to .htaccess files, if Apache’s document root
# concurs with nginx’s one
#
location ~ /\.ht {
deny all;
}
}

# another virtual host using mix of IP-, name-, and port-based configuration
#
#server {
# listen 8000;
# listen somename:8080;
# server_name somename alias another.alias;
# root html;
# index index.html index.htm;
#
# location / {
# try_files $uri $uri/ /index.html;
# }
# }
