如何确定在PHP-FPM过程中正在执行哪个脚本

Question

我正在运行nginx + php-fpm.有什么方法我怎么知道每个PHP进程在做什么？像apache中的扩展mod_status,我可以看到使用PID x的apache进程处理URL y.我不确定PHP进程是否知道URL,但获取脚本路径和名称就足够了.

经过一些谷歌搜索和浏览PHP.net错误跟踪系统后,我找到了解决方案.它自PHP 5.3.8或5.3.9起可用,但似乎没有记录.根据功能请求#54577,状态页面支持选项full,该选项将分别显示每个工作程序的状态.例如,URL将是http://server.com/php-status?full和示例输出如下所示:

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,虽然它不像mod_status那样详细.来自php-fpm配置文件/etc/php-fpm.d/www.conf(在CentOS 6上)

; 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

如果启用此功能,则可以将路径从nginx传递到PHP-FPM的套接字​​/端口,然后可以查看状态页面.

nginx.conf:

location /status {

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

}

cgi命令行更方便:

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