启动Apache时,Passenger/mod_rails无法在Fedora 12中初始化

Question

我正在使用Passenger设置服务器以在Fedora 12上运行Ruby on Rails应用程序.

我正处于安装Passenger的阶段,按规定进行设置,但在重新启动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,它会在/ tmp中创建一个文件:

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

如果我通过直接启动mongrel运行应用程序mongrel_rails start -e production,我看到以下内容:

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

同样,错误指向/ tmp目录的权限问题.

我不知道解决方案是什么.我不确定它是否与简单的目录权限或Fedora的SELinux安全性有关.

任何帮助,将不胜感激.谢谢.

Answer 1

我和Fred做了同样的事情,不过一次只做一次错误:

1. 通过运行进入许可模式 setenforce 0
2. 重启apache,点击你的网站并正常使用它一段时间
3. 跑 grep httpd /var/log/audit/audit.log | audit2allow -M passenger
4. semodule -i passenger.pp
5. 通过运行返回执行模式 setenforce 1
6. 重启apache并测试你的网站 - 希望它一切都像以前一样工作!

请注意,这基本上是Centos SELinux帮助程序的一个具体示例- 请查看它.
