PHP-FPM 不写入错误日志

Question

我刚刚安装了一个 nginx+php-fpm 服务器。一切似乎都很好，只是 PHP-FPM 从不将错误写入其日志。

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

 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 浏览器上查看错误输出。 nginx 错误日志也使用相同的消息说明 fpm 的 stderr 输出。我已经检查过用户是否对指定的日志文件夹具有写入（我什至尝试过 777）权限。甚至指定的error.log文件也被php-fpm成功创建了。然而，日志文件始终是空的，无论从 php 脚本中发生了什么离谱的错误。

这是怎么回事？

Answer 1

在带有 php8 的 alpine 3.15 上，我在 /var/log/php8/error.log 上找到了

/var/log/php8 # cat error.log
 16:10:52] NOTICE: fpm is running, pid 14
 16:10:52] NOTICE: ready to handle connections

我也有这个：

 catch_workers_output = yes
