如何确定在PHP-FPM过程中执行哪个脚本

Question

我正在运行nginx + php-fpm。有什么方法可以让我知道每个PHP进程在做什么？像apache中的扩展mod_status，我可以看到带有PID x的apache进程正在处理URL y。我不确定PHP过程是否知道URL，但获取脚本路径和名称就足够了。

一些谷歌搜索小时，浏览PHP.net错误跟踪系统后，我已经找到了解决办法。它从PHP 5.3.8或5.3.9开始可用，但似乎没有记录。根据功能请求#54577，状态页面支持选项full，它将单独显示每个工人的状态。因此，例如URL将http://server.com/php-status?full和样本输出如下：

pid:     22816 
state:    Idle 
start time:   22/Feb/2013:15:03:42 +0100 
start since:   10933 
requests:    28352 
request duration:  1392 
request method:  GET 
request URI:   /ad.php?zID=597 
content length:  0 
user:     - 
script:    /home/web/server.com/ad/ad.php 
last request cpu:  718.39 
last request memory: 1310720

PHP-FPM有一个内置的状态监视器，虽然它不如mod_status的细节。从PHP-FPM配置文件/etc/php-fpm.d/www.conf（在CentOS 6）

; The URI to view the FPM status page. If this value is not set, no URI will be 
; recognized as a status page. By default, the status page shows the following 
; information: 
; accepted conn - the number of request accepted by the pool; 
; pool    - the name of the pool; 
; process manager - static or dynamic; 
; idle processes - the number of idle processes; 
; active processes - the number of active processes; 
; total processes - the number of idle + active processes. 
; The values of 'idle processes', 'active processes' and 'total processes' are 
; updated each second. The value of 'accepted conn' is updated in real time. 
; Example output: 
; accepted conn: 12073 
; pool:    www 
; process manager: static 
; idle processes: 35 
; active processes: 65 
; total processes: 100 
; By default the status page output is formatted as text/plain. Passing either 
; 'html' or 'json' as a query string will return the corresponding output 
; syntax. Example: 
; http://www.foo.bar/status 
; http://www.foo.bar/status?json 
; http://www.foo.bar/status?html 
; Note: The value must start with a leading slash (/). The value can be 
;  anything, but it may not be a good idea to use the .php extension or it 
;  may conflict with a real PHP file. 
; Default Value: not set 
;pm.status_path = /status 

如果启用此，您可以通过从nginx的路径到您的插座/端口PHP-FPM，您可以查看状态页面。

nginx.conf：

location /status { 

    include fastcgi_params; 
    fastcgi_pass unix:/var/lib/php/php-fpm.sock; 

}

CGI命令行更方便易：

SCRIPT_NAME=/status \ 
SCRIPT_FILENAME=/status \ 
REQUEST_METHOD=GET \ 
cgi-fcgi -bind -connect 127.0.0.1:9000
