PHP-FPM不会写入错误日志 [英] PHP-FPM doesn't write to error log

问题描述

我刚刚安装了nginx + php-fpm服务器.一切似乎都很好，只是PHP-FPM从未向其日志写入错误.

I've just installed a nginx+php-fpm server. Everything seems fine except that PHP-FPM never writes error to its log.

fpm.conf

[default]
listen = /var/run/php-fpm/default.sock
listen.allowed_clients = 127.0.0.1
listen.owner = webusr
listen.group = webusr
listen.mode = 0666
user = webusr
group = webusr
pm = dynamic
pm.max_children = 50
pm.start_servers = 5
pm.min_spare_servers = 5
pm.max_spare_servers = 35
pm.status_path = /php/fpm/status
ping.path = /php/fpm/ping
request_terminate_timeout = 30s
request_slowlog_timeout = 10s
slowlog = /var/log/php-fpm/default/slow.log
chroot = /var/www/sites/webusr
catch_workers_output = yes
env[HOSTNAME] = mapsvr.mapking.com
php_flag[display_errors] = on
php_admin_value[error_log] = /var/log/php-fpm/default/error.log
php_admin_flag[log_errors] = on

nginx.conf

nginx.conf

server
{
  listen        80 default_server;
  server_name   _;

  charset       utf-8;
  access_log    /var/log/nginx/access.log rest;

  include       conf.d/drops.conf.inc;

  location      /
  {
    root        /var/www/sites/webusr/htdocs;
    index       index.html index.htm index.php;
  }

  # pass the PHP scripts to FastCGI server listening on socket
  #
  location      ~ \.php$
  {
    root           /var/www/sites/webusr/htdocs;
    include        /etc/nginx/fastcgi_params;
    fastcgi_index  index.php;
    fastcgi_param  SCRIPT_FILENAME /htdocs/$fastcgi_script_name;
    if (-f $request_filename)
    {
      fastcgi_pass   unix:/var/run/php-fpm/default.sock;
    }
  }

  location      = /php/fpm/status
  {
    include        /etc/nginx/fastcgi_params;
    fastcgi_param  SCRIPT_FILENAME $document_root$fastcgi_script_name;
    fastcgi_pass   unix:/var/run/php-fpm/default.sock;
  }

  location      = /php/fpm/ping
  {
    include        /etc/nginx/fastcgi_params;
    fastcgi_param  SCRIPT_FILENAME $document_root$fastcgi_script_name;
    fastcgi_pass   unix:/var/run/php-fpm/default.sock;
  }

  # redirect server error pages to the static page /50x.html
  #
  error_page    500 502 503 504  /50x.html;
  location      = /50x.html
  {
    root        /usr/share/nginx/html;
  }
}

我制作了一个错误的php脚本并运行，并在Web浏览器上看到错误输出.此外，nginx错误日志还使用相同的消息声明了fpm的stderr输出.我检查了用户是否已向指定的日志文件夹写入(甚至尝试过777)权限.甚至指定的error.log文件也已由php-fpm成功创建.但是，无论php脚本发生了什么令人毛骨悚然的错误，日志文件始终为空.

I've made an erroneous php script and run, and see error output on the web browser. Also nginx error log states stderr output from fpm with the same message. I've check that the user have write (I've even tried 777) permission to the appointed log folder. Even the appointed error.log file has be created successfully by php-fpm. However, the log file is always empty, no matter what outrageous error has been made from php script.

这是怎么回事?

[不久后找到原因]

[Found the reason quite a while later]

是许可.将所有者更改为网站的用户即可解决问题.

It was permission. Changed the owner to the sites's users solved the problem.

推荐答案

这对我有用:

; Redirect worker stdout and stderr into main error log. If not set, stdout and
; stderr will be redirected to /dev/null according to FastCGI specs.
; Default Value: no
catch_workers_output = yes

要编辑的文件是配置所需池的文件. 默认情况下，它是:/etc/php-fpm.d/www.conf

The file to edit is the file that configure your desired pool. By default its: /etc/php-fpm.d/www.conf
