搭建高性能web服务器之nginx通用模板

对于php环境，很多时候不是nginx，php，MySQL都安装好了可以解析php脚本代码了，我们还需要对nginx主配置文件做一些配置更改，比如fastcgi配置，nginx网络连接，文件优化等相关配置，这些都需要手动在nginx.conf文件中增加，另外在配置nginx.conf中，为了不破坏配置文件（备份除外），我们对于web站点那部分通常都利用include引用，如下所示，为一个nginx.conf通用配置模板，分为两大部分：1.nginx.conf ;2.include引用的web站点配置

1.nginx.conf配置模板示例

#user  nobody;

        #
        #location ~ \.php$ {

        # pass the PHP scripts to FastCGI server listening on 127.0.0.1:9000

    # another virtual host using mix of IP-, name-, and port-based configuration

    #}

}

2.include引用的web站点模板示例

vim /etc/nginx/extra/web.conf
server {
     listen       80 default backlog=65535;
     server_name localhost;
     root    /usr/local/www;
     index  index.php index.html ;

     location ~ \.php$ {
                   fastcgi_pass   127.0.0.1:9000;
                   fastcgi_index  index.php;
                   fastcgi_split_path_info ^(.+\.php)(.*)$;
                   fastcgi_param PATH_INFO $fastcgi_path_info;
                   fastcgi_param SCRIPT_FILENAME $document_root$fastcgi_script_name;
                   include        fastcgi_params;
                   fastcgi_cache fastcgi_nginx; 
                   fastcgi_cache_valid 200 302 1h; 
                   fastcgi_cache_valid any 1m;   
                   fastcgi_cache_min_uses 1; 
                   fastcgi_cache_use_stale error timeout invalid_header http_500 http_502 
                   http_503 http_504;
                   fastcgi_cache_key "$request_method://$host$request_uri";
        }
       i
