Where does PHP store the error log? (php5, apache, fastcgi, cpanel)
提问by PHPLOVER
I am on shared hosting and have Cpanel, Apache, PHP is run by fastcgi. Where does PHP store the error log?
我在共享主机上，并且有 Cpanel、Apache、PHP 由 fastcgi 运行。PHP 在哪里存储错误日志？
Is there any other way I can find the error log on shared hosting environment instead of having to go through entire site structure to look for error_log files?
有没有其他方法可以在共享托管环境中找到错误日志，而不必遍历整个站点结构来查找 error_log 文件？
I have access to the php.ini(I am using PHP version 5.2.16).
我可以访问php.ini（我使用的是 PHP 5.2.16 版）。

PHP stores error logs in /var/log/apache2if PHP is an apache2 module.
Shared hosts are often storing log files in your root directory /logsubfolder.
But...if you have access to a php.inifile you can do this:
/var/log/apache2如果 PHP 是 apache2 模块，则 PHP 会存储错误日志。共享主机通常将日志文件存储在您的根目录/log子文件夹中。但是...如果您有权访问php.ini文件，则可以执行以下操作：
error_log = /var/log/php-scripts.log
According to rinogo's comment: If you're using cPanel, the master log file you're probably looking for is stored (by default) at
根据rinogo的评论：如果您使用的是 cPanel，则您可能正在查找的主日志文件（默认情况下）存储在
/usr/local/apache/logs/error_log
If all else fails you can check the location of the log file using
如果所有其他方法都失败了，您可以使用以下命令检查日志文件的位置
<?php phpinfo(); ?>

It appears that by default php does not logerrors anywhere, the error_logkey in php.ini is commented out in all the install's I've seen.
似乎默认情况下 php不会在任何地方记录错误，error_logphp.ini 中的键在我见过的所有安装中都被注释掉了。
Generally I:
一般我：
- look for php.ini files.
locate php.ini. Search these files for the
error_reportingvalue;Which should be set to whatever amalgamation of php log levels are enough for you.,
Eg:
E_ALL & ~E_DEPRECATED & ~E_STRICTCheck the
error_logvalue to make sure it points to an actual place and is not commented out.The default value doesn't give a full path, only a file name, I don't know where this path resolves to normally. Probably
/var/log/.
- 寻找 php.ini 文件。
locate php.ini. 在这些文件中搜索
error_reporting值；哪个应该设置为 php 日志级别的任何合并对您来说就足够了。,
例如：
E_ALL & ~E_DEPRECATED & ~E_STRICT检查该
error_log值以确保它指向实际位置并且没有被注释掉。默认值没有给出完整路径，只有文件名，我不知道这个路径通常解析到哪里。大概
/var/log/。

You should use absolute path when setting error_logvariable in your php.ini file, otherwise, error logs will be stored according to your relative path.
在 php.ini 文件中设置error_log变量时应使用绝对路径，否则错误日志将根据您的相对路径存储。
error_log = /var/log/php.errors
Other solution would be writing simple script which would list all error logs files from directory tree.
其他解决方案是编写简单的脚本，该脚本将列出目录树中的所有错误日志文件。

And you can view tail like this:
你可以像这样查看尾巴：

The best way is to look in your httpd.conf file and see what the default is. It could also be overridden by your specific virtual host. I start by looking at /etc/httpd/conf/httpd.confor /etc/apache2/httpd.confand search for error_log. It could be listed as either /var/log/httpd/error_log or /var/log/apache2/error_logbut it might also be listed as simply logs/error_log.
最好的方法是查看您的 httpd.conf 文件并查看默认值。它也可以被您的特定虚拟主机覆盖。我首先查看/etc/httpd/conf/httpd.confor/etc/apache2/httpd.conf并搜索 error_log。它可以列为 /var/log/httpd/error_log /var/log/apache2/error_log，也可能列为简单的logs/error_log.
In this case it is a relative path, which means it will be under /etc/httpd/logs/error_log. If you still can't find it check the bottom of your httpd.conf file and see where your virtual hosts are included. It might be in /etc/httpd/conf.d/<- as "other" or "extra". Your virtual host could override it then with ErrorLog "/path/to/error_log".
在这种情况下，它是一个相对路径，这意味着它将在/etc/httpd/logs/error_log. 如果您仍然找不到它，请检查您的 httpd.conf 文件的底部并查看您的虚拟主机的位置。它可能在 /etc/httpd/conf.d/<- 中作为“其他”或“额外”。然后您的虚拟主机可以使用 ErrorLog "/path/to/error_log" 覆盖它。

If you have build Apache and PHP from source, then the error logs by default is generated at your ${Apache install dir}/logs/error_logi.e generally /usr/local/apache2/logs/error_log. Else, if you have installed it from repository, you will find it at /var/log/apache2/error_log.You can set the path in your php.inialso and verify it by invoking phpinfo().
如果您从源代码构建了 Apache 和 PHP，那么默认情况下错误日志会在您的${Apache install dir}/logs/error_logie 中生成/usr/local/apache2/logs/error_log。否则，如果您已从存储库安装它，您将在 中找到它。/var/log/apache2/error_log您可以在您的php.ini还中设置路径并通过调用来验证它phpinfo()。
