截断 PHP-FPM / NGINX 日志行

Question

我的 PHP-FPM / NGINX 日志中有很多行被截断为 2048 字节，如下所示：

2022/05/15 16:06:16 [error] 899#899: *29892 FastCGI sent in stderr: "com/wordpress/wp-includes/class-wp-query.php on line 4121PHP message: PHP Warning:  Attempt to read property "post_title" on null in /var/www/ultimatehackingkeyboard.com/wordpress/wp-includes/class-wp-qu

我看过很多类似的问题，有人建议重新编译 NGINX，但我不敢相信没有其他解决方案。

我设置了以下选项，据我所知，这些选项应该可以解决问题，但它们不能：

log_errors_max_len = 8000 在 /etc/php/8.0/fpm/php.ini.
log_limit = 8000 在 /etc/php/8.0/fpm/php-fpm.conf.
decorate_workers_output = no 在 /etc/php/8.0/fpm/pool.d/www.conf

Answer 1

1024 个字符的限制是 hard-coded php-fpm 而不是 nginx。

如果你想超过 2048 个字符，你需要 re-compiled nginx 和 php-fpm，否则只 php-fpm.

这里有一个包含 8192 个字符补丁的完整解决方案：https://forums.freebsd.org/threads/56543/

Answer 2

您可以更改配置中的日志记录设置，这样错误就不会被打印到 STDERR 并渗透到具有自身约束的各个中间层，而是被 PHP 直接写入文件.

配置指令很简单：

error_log = /path/to/file

参考： https://www.php.net/manual/en/errorfunc.configuration.php#ini.error-log

Answer 3

您可以将错误日志发送到标准输出并使用其他软件记录到那里。

www.conf

php_admin_value[error_log] = /dev/stdout
catch_workers_output = yes
