这篇文章给大家介绍Nginx+PHP配置相关进程的简要介绍有哪些,内容非常详细,感兴趣的小伙伴们可以参考借鉴,希望对大家能有所帮助。
Nginx+PHP配置有很多的技术应用技巧,网管员在学习的时候都需要注意相关的知识。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/usr/local/webserver/php/etc/目录中创建php-fpm.conf文件:
rm -f /usr/local/php/etc/php-fpm.conf 我的默认没有这个vi /usr/local/php/etc/php-fpm.conf
输入以下内容(如果您安装 Nginx + PHP 用于程序调试,请将以下的<value name="display_errors">0</value>改为<value name="display_errors">1</value>,以便显示PHP错误信息,否则,Nginx 会报状态为500的空白错误页):
看到配置中有下面
Unix user of processes <value name="user">www</value> Unix group of processes <value name="group">www</value>
我的是nobody所以改成nobody这个值
<value name="max_children">200</value>
启动Nginx+PHP配置-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/参考配置文件中的那个max_children我暂时改为32内部测试机),用户为nobody:
ulimit -SHn 51200 #/usr/local/php/sbin/php-fpm start Starting php_fpm done [root@test php-5.2.6]# ps fax|grep fpm 17489 pts/2 S+ 0:00 \_ grep fpm 17453 ? Ss 0:00 /usr/local/php/bin/php-cgi --fpm 17454 ? S 0:00 \_ /usr/local/php/bin/php-cgi --fpm 17455 ? S 0:00 \_ /usr/local/php/bin/php-cgi --fpm 17456 ? S 0:00 \_ /usr/local/php/bin/php-cgi --fpm [root@test php-5.2.6]# ps fax|grep fpm|wc -l
注:/usr/local/php/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

为了让Nginx+PHP配置支持
location ~ .*\.php?$ { include fcgi.conf; #fastcgi_pass unix:/tmp/php-cgi.sock; fastcgi_pass 127.0.0.1:9000; fastcgi_index index.php; }
增加上面这段到我的server段,在/usr/local/nginx/conf/目录中创建fcgi.conf文件
vi /usr/local/nginx/conf/fcgi.conf
fastcgi_param GATEWAY_INTERFACE CGI/1.1;
fastcgi_param SERVER_SOFTWARE nginx;
fastcgi_param QUERY_STRING $query_string;
fastcgi_param REQUEST_METHOD $request_method;

fastcgi_param CONTENT_LENGTH $content_length;

fastcgi_param REQUEST_URI $request_uri;
