乘客/mod_rails在启动Apache时无法在Fedora 12中初始化 [英] Passenger/mod_rails fails to initialize in Fedora 12 when starting Apache
问题描述
我正在设置一个服务器，以使用乘客"在Fedora 12上运行Ruby on Rails应用程序.
I am in the process of setting up a server to run a Ruby on Rails application on Fedora 12, using Passenger.
我正在安装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:
I am at the stage where I've installed Passenger, set it up as prescribed, but get the following errors when I restart Apache:
[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:
As you can see, there is a permissions problem when Passenger is trying to initialize:
[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)
启动Apache时，它确实在/tmp中创建了一个文件:
When Apache is starts, it does create a file in /tmp:
d-ws--x--x. 2 root root 4096 2010-01-13 16:04 passenger.26117
如果相反，我直接通过mongrel_rails start -e production启动 mongrel 来运行应用程序，则会看到以下内容:
If instead I run the app by firing up mongrel directly with mongrel_rails start -e production, I see the following:
ActiveRecord::StatementInvalid (Mysql::Error: Can't create/write to file '/tmp/#sql_5d3_0.MYI' (Errcode: 13): SHOW FIELDS FROM `users`):
再次错误提示/tmp 目录的权限问题.
Again the error points to permission issues with the /tmp directory.
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.
I am at a loss as to what the solution is. I'm not sure if it is related to simply directory permissions or Fedora's SELinux security.
任何帮助将不胜感激.谢谢.
Any help would be appreciated. Thanks.
推荐答案
我所做的工作与Fred相同，只是一次没有犯一个错误:
I did the same as Fred, except that instead of doing it one error at a time:
- 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正常使用一段时间
- 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！
- Go into permissive mode by running
setenforce 0 - Restart apache, and hit your site and use it for a while as normal
- Run
grep httpd /var/log/audit/audit.log | audit2allow -M passenger semodule -i passenger.pp- Go back to enforcing mode by running
setenforce 1 - Restart apache and test your site - hopefully it should all be working as before!
请注意，这基本上是 Centos SELinux 帮助-查看.
Note that this is basically a specific example of the procedure on the Centos SELinux help - check it out.
