原理

nginx把网站导向到wordpress安装目录, 对于php文件, 采用fastcgi的方式, 导向到一个php-fastcgi服务器上面处理.

具体安装过程

新建一个wordpress nginx配置文件: /etc/nginx/site-avariable/wordpress

里面几个参数需要改: server_name就是你网站的地址, root指向wordpress, fastcgi_param就是下面fastcgi脚本文件.

          server{
                  listen 80; #or change this to your public IP address eg 1.1.1.1:80
                  server_name wordpress; #change this to the domain name, for example www.myblog.com
                  access_log /var/log/wordpress.access_log;
                  error_log /var/log/wordpress.error_log;
          
                  location / {
                    root /home/your-user-name/Sites/wordpress;
                    index index.php index.html index.htm;
          
                    # this serves static files that exist without running other rewrite tests
                    if (-f $request_filename) {
                        expires 30d;
                        break;
                    }
          
                    # this sends all non-existing file or directory requests to index.php
                    if (!-e $request_filename) {
                        rewrite ^(.+)$ /index.php?q=$1 last;
                    }
                  }
          
                  location ~ \.php$ {
                      fastcgi_pass    127.0.0.1:9000;
                      fastcgi_index   index.php;
                      fastcgi_param   SCRIPT_FILENAME /home/your-user-name/Sites/wordpress$fastcgi_script_name;
                      include         fastcgi_params;
                  }
          }
          

然后重启nginx:

          sudo service nginx restart
          

php fastcgi脚本: php-fastcgi

里面user你随便定, 但是要能够访问和修改wordpress目录, 我是直接用普通用户了(wordpress也是普通用户下载的)

          #!/bin/bash
          
          FASTCGI_USER=www-data
          FASTCGI_GROUP=www-data
          ADDRESS=127.0.0.1
          PORT=9000
          PIDFILE=/var/run/php-fastcgi/php-fastcgi.pid
          CHILDREN=6
          PHP5=/usr/bin/php5-cgi
          
          /usr/bin/spawn-fcgi -a $ADDRESS -p $PORT -P $PIDFILE -C $CHILDREN -u $FASTCGI_USER -g $FASTCGI_GROUP -f $PHP5
          

写好后, 执行这个文件就可以了:

          chmod u+x php-fastcgi
          ./php-fastcgi
          

这样就新建了一个一个php-fastcgi服务器. nginx发现php文件的时候, 就会交由这个服务器处理.

然后你就可以跟着wordpress教程一步步做了: http://codex.wordpress.org/zh-cn:%E5%AE%89%E8%A3%85_WordPress

对了, 里面还有设置mysql服务器的步骤, 基本上按照上面的教程来就行了.
