Ruby on rails 3 CentOS上的Apache Phusion乘客无法启动，因为更新到4.0.6后/tmp上的权限被拒绝

我知道这有很多重复，但没有一个有帮助，我已经将乘客从3.0.19更新到4.0.6，突然我得到了一个禁止的错误， 我查看了日志，错误日志显示

[ 2013-07-05 12:01:51.3604 2639/7fec9151f720 agents/HelperAgent/Main.cpp:596 ]: PassengerHelperAgent online, listening at unix:/xxxx/tmp/passenger.1.0.2634/generation-0/request

我知道这是因为乘客无法创建/xxxx/tmp/passenger.1.0.2634/generation-0/request，但我不知道为什么

我试过了

1.在conf文件中将用户设置为apache

2.将tmp文件夹设置为MyRails文件中的tmp，而不是/tmp

3.检查rails文件夹中的所有文件和文件夹是否归apache:apache所有

4.SeLinux已打开，已永久禁用它

下面是我当前的apacheconf设置

   LoadModule passenger_module /usr/local/lib/ruby/gems/1.9.1/gems/passenger-4.0.6/buildout/apache2/mod_passenger.so
   PassengerRoot /usr/local/lib/ruby/gems/1.9.1/gems/passenger-4.0.6
   PassengerDefaultRuby /usr/local/bin/ruby
   PassengerTempDir /xxxx/tmp

   PassengerUserSwitching off
   PassengerDefaultUser apache

   <VirtualHost *:80>
      ServerName xxxxxxx.com
      # !!! Be sure to point DocumentRoot to 'public'!
      DocumentRoot /xxxx/public

       <Directory /xxxx/public>
         # This relaxes Apache security settings.
         AllowOverride all
         # MultiViews must be turned off.
         Options -MultiViews
      </Directory>
   </VirtualHost>   

LoadModule-passenger\u-module/usr/local/lib/ruby/gems/1.9.1/gems/passenger-4.0.6/buildout/apache2/mod\u-passenger.so
PassengerRoot/usr/local/lib/ruby/gems/1.9.1/gems/passer-4.0.6
PassengerDefaultRuby/usr/local/bin/ruby
PassengerTempDir/xxxx/tmp
乘客关掉
PassengerDefaultUser apache
服务器名xxxxxxx.com
# !!! 确保将DocumentRoot指向“public”！
DocumentRoot/xxxx/public
#这放松了Apache的安全设置。
允许超越所有
#必须关闭“多视图”。
选项-多视图

现在我又回到了早期版本，问题似乎已经平息了。

这是4.0.6中的回归。它已在刚刚发布的4.0.7中修复。

感觉这是一个特定于版本的问题，这必须发生在生产服务器更新上。
