By default, /var/log/apache2/error.log.
默认情况下，/var/log/apache2/error.log.
This can be configured in /etc/php5/apache2/php.ini
这可以配置在 /etc/php5/apache2/php.ini
You can also define a specific error log file for each VirtualHost in Apache. If you have any VirtualHost defined in /etc/apache2/sites-available/and enabled in /etc/apache2/sites-enabled(enable with sudo a2ensite [your-virtualhost-definition-file]), you can change the error log by adding the following line inside your VirtualHost config:
您还可以为 Apache 中的每个 VirtualHost 定义一个特定的错误日志文件。如果您/etc/apache2/sites-available/在/etc/apache2/sites-enabled（启用sudo a2ensite [your-virtualhost-definition-file]）中定义并启用了任何 VirtualHost ，您可以通过在 VirtualHost 配置中添加以下行来更改错误日志：
ErrorLog ${APACHE_LOG_DIR}/[your-vhost]-error.log
That might be useful if you have a lot of vhosts and want to split where they report the errors.
如果您有很多虚拟主机并且想要拆分它们报告错误的位置，这可能很有用。
Also, you can watch your error log live by issuing the following command (adapt to your own log file if different from the default):
此外，您可以通过发出以下命令来实时查看错误日志（如果与默认值不同，则适应您自己的日志文件）：
sudo tail -f /var/log/apache2/error.log
