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0改为1，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 www Unix group of processes www
我的是nobody所以改成nobody这个值
200
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
All relative paths in this config are relative to php's install prefix Pid file /usr/local/php/logs/php-fpm.pid Error log file /usr/local/php/logs/php-fpm.log Log level notice When this amount of php processes exited with SIGSEGV or SIGBUS ... 10 ... in a less than this interval of time, a graceful restart will be initiated. Useful to work around accidental curruptions in accelerator's shared memory. 1m Time limit on waiting child's reaction on signals from master 5s Set to 'no' to debug fpm yes Name of pool. Used in logs and stats. default Address to accept fastcgi requests on. Valid syntax is 'ip.ad.re.ss:port' or just 'port' or '/path/to/unix/socket' 127.0.0.1:9000 Set listen(2) backlog -1 Set permissions for unix socket, if one used. In Linux read/write permissions must be set in order to allow connections from web server. Many BSD-derrived systems allow connections regardless of permissions. 0666 Additional php.ini defines, specific to this pool of workers. /usr/sbin/sendmail -t -i 1 Unix user of processes nobody Unix group of processes nobody Process manager settings Sets style of controling worker process count. Valid values are 'static' and 'apache-like' static Sets the limit on the number of simultaneous requests that will be served. Equivalent to Apache MaxClients directive. Equivalent to PHP_FCGI_CHILDREN environment in original php.fcgi Used with any pm_style. 200 Settings group for 'apache-like' pm style Sets the number of server processes created on startup. Used only when 'apache-like' pm_style is selected 20 Sets the desired minimum number of idle server processes. Used only when 'apache-like' pm_style is selected 5 Sets the desired maximum number of idle server processes. Used only when 'apache-like' pm_style is selected 250 Time limit on waiting execution of single request Should be used when 'max_execution_time' ini option does not terminate execution for some reason 31s Set open file desc rlimit 51200 Set max core size rlimit 0 Chroot to this directory at the start Chdir to this directory at the start Redirect workers' stdout and stderr into main error log. If not set, they will be redirected to /dev/null, according to FastCGI specs yes How much requests each process should execute before respawn. Useful to work around memory leaks in 3rd party libraries. For endless request processing please specify 0 Equivalent to PHP_FCGI_MAX_REQUESTS 51200 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. 127.0.0.1 Pass environment variables like LD_LIBRARY_PATH All $VARIABLEs are taken from current environment $HOSTNAME /usr/local/bin:/usr/bin:/bin /tmp /tmp /tmp $OSTYPE $MACHTYPE 2
为了让Nginx+PHP配置支持
location ~ .*\.php?$ { 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_TYPE $content_type;
fastcgi_param CONTENT_LENGTH $content_length;
fastcgi_param SCRIPT_FILENAME $document_root$fastcgi_script_name;
fastcgi_param SCRIPT_NAME $fastcgi_script_name;
fastcgi_param REQUEST_URI $request_uri;

fastcgi_param DOCUMENT_ROOT $document_root;
fastcgi_param SERVER_PROTOCOL $server_protocol;
fastcgi_param REMOTE_ADDR $remote_addr;
fastcgi_param REMOTE_PORT $remote_port;
fastcgi_param SERVER_ADDR $server_addr;
fastcgi_param SERVER_PORT $server_port;
fastcgi_param SERVER_NAME $server_name;
# PHP only, required if PHP was built with --enable-force
