我正在运行 Apache 和 Passenger 来托管我的 Rails 应用程序。我不得不经常进行硬重启。当我查看此乘客记忆统计数据时。我需要知道我的 rails 应用程序是否有误导性配置。什么可以
阿帕奇配置：
<VirtualHost *:80>
ServerName example.com
DocumentRoot /var/www/mywebapp/public
RailsEnv production
# Possible values include: debug, info, notice, warn, error, crit, alert, emerg.
LogLevel warn
ErrorLog ${APACHE_LOG_DIR}/error.mywebapp.log
CustomLog ${APACHE_LOG_DIR}/access.mywebapp.log combined
</VirtualHost>
