ruby-on-rails - 乘客/mod_rails在启动Apache时无法在Fedora 12中初始化

Question

我正在设置一个服务器，以使用Passenger在Fedora 12上运行Ruby on Rails应用程序。

我现在处于安装Passenger的阶段，按照规定进行设置，但是在重新启动Apache时出现以下错误:

[Wed Jan 13 15:41:38 2010] [notice] caught SIGTERM, shutting down

如您所见，Passenger尝试初始化时存在权限问题:

[Wed Jan 13 15:41:40 2010] [error] *** Passenger could not be initialized because of this error: Cannot create FIFO file /tmp/passenger.25235/.guard: Permission denied (13)

当Apache启动时，它确实在/tmp中创建了一个文件:

d-ws--x--x. 2 root  root  4096 2010-01-13 16:04 passenger.26117

相反，如果我通过直接使用 mongrel_rails start -e production触发mongrel来运行应用程序，则会看到以下内容:

ActiveRecord::StatementInvalid (Mysql::Error: Can't create/write to file '/tmp/#sql_5d3_0.MYI' (Errcode: 13): SHOW FIELDS FROM `users`):

该错误再次指出/tmp目录的权限问题。

我对解决方案不知所措。我不确定它是否仅与目录权限或Fedora的SELinux安全性有关。

任何帮助，将不胜感激。谢谢。

Answer 1

我做了与Fred相同的事情，只是没有一次犯一个错误:

通过运行setenforce 0

进入宽松模式

重新启动apache，然后访问您的网站并像正常

一样使用它一段时间

运行grep httpd /var/log/audit/audit.log | audit2allow -M passenger

semodule -i passenger.pp

通过运行setenforce 1

返回到强制模式

重新启动apache并测试您的网站-希望它应该能像以前一样正常工作!

请注意，这基本上是 Centos SELinux帮助上过程的特定示例- checkout 。
