最好的方法是查看httpd.conf文件，看看默认值是什么。它也可以被特定的虚拟主机覆盖。我首先查看/etc/httpd/conf/httpd.conf或/etc/apache2/httpd.conf并搜索error_log。它可以被列出为/var/log/httpd/error_log或/var/log/apache2/error_log，但也可以简单地列出为logs/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下。如果仍然找不到它，请检查httpd.conf文件的底部，并查看虚拟主机包含在哪里。它可能在/etc/httpd/conf中。D / <-作为“其他”或“额外”。你的虚拟主机可以用ErrorLog "/path/to/error_log"覆盖它。

无论你想要它在哪里，如果你在函数调用中设置它:

error_log($errorMessageforLog . "\n", 4, 'somePath/SomeFileName.som');

你可以在下面看到一个帐户的php错误:

/home/username/logs/domain_tld.php.error.log

可以在全局和本地设置php错误日志。

Globally through WHM: WHM -->> MultiPHP INI Editor --> "Editor Mode" Select the version of PHP you would like to set the error log Edit the parameter error_log. error_log = "/some/path" Change the filename to the desired error log file Save changes Locally though cPanel: CPanel -->> MultiPHP INI Editor --> "Editor Mode" Select the version of PHP you would like to set the error log Edit the parameter error_log. error_log = "/some/path" Change the filename to the desired error log file Home directory will set the option for all domains, addons, and subdomains configured on the account A specific domain will limit the change to that domain, or, in the case of an addon domain, the addon and the matching subdomain Save changes If PHP-fpm is enabled: WHM --> MultiPHP Manager Find the domain you'd like to change the error log location for Click "Edit PHP-FPM" Change the log location in "The error log file (error_log)" relative to the folder "logs" within the user's home directory Save changes

就像这样:

sudo locate error.log | xargs -IX grep -iH "errorlog" X

or

sudo locate error_log | xargs -IX grep -iH "errorlog" X

or

sudo find / -iname "error?log" 2>/dev/null | xargs -IX grep -iH "errorlog" X

如何找到你的PHP错误日志在Linux:

sudo updatedb

[sudo] password for eric:

sudo locate error_log

/var/log/httpd/error_log

另一种等效的方法:

sudo find / -name "error_log" 2>/dev/null

/var/log/httpd/error_log

在LAMP环境中，PHP错误默认指向下面这个文件。

/var/log/httpd/error_log

所有访问日志分为:

/var/log/httpd/access_log
