v. 创建php-fpm配置文件（php-fpm是为PHP打的一个FastCGI管理补丁，可以平滑变更php.ini配置而无需重启php-cgi）：

　　在/data/php-5.2.10/etc/目录中创建php-fpm.conf文件：
　　rm -f /data/php-5.2.10/etc/php-fpm.conf
　　vi /data/php-5.2.10/etc/php-fpm.conf
　　输入：（如用于调试，请将display_errors 由0改为1，否则出错只会报500的错误页）

        Useful to work around memory leaks in 3rd party libraries.

        For endless request processing please specify 0

        Equivalent to PHP_FCGI_MAX_REQUESTS

      102400

        Comma separated list of ipv4 addresses of FastCGI clients that allowed to connect.

        Equivalent to FCGI_WEB_SERVER_ADDRS environment in original php.fcgi (5.2.2+)

        Makes sense only with AF_INET listening socket.

启动php-cgi进程，监听127.0.0.1的9000端口，进程数为200（如果服务器内存小于3GB，可以只开启64个进程），用户为www：

　　ulimit -SHn 51200
　　/data/php-5.2.10/sbin/php-fpm start
　　注：/data/php-5.2.10/sbin/php-fpm还有其他参数，包括：start|stop|quit|restart|reload|logrotate
　　修改php.ini后不重启php-cgi，重新加载配置文件使用reload。
