在Apache和Mongrel上为Rails应用程序设置虚拟主机

Question

我有一台在Apache上运行3个站点的Linux服务器。我们称之为RailsApp1，RailsApp2和SimpleApp。两个Rails应用程序都使用Mongrel群集。另一个应用程序只是一个HTML文件。我在Apache中为每个站点设置了不同的虚拟主机文件，以及两个Rails站点的mongrel_cluster.yml文件（所有代码均位于底部）。

随着一切设置，我可以启用在Apache的网站就好了。我可以为每个Rails站点启动Mongrel群集。事实上，在我的浏览器中访问www.simpleapp.com和www.railsapp1.com工作得很好。 但是，www.railsapp2.com给了我很多麻烦。服务器不用显示railsapp2的代码，而是返回railsapp1的HTML。如果我在Apache中禁用railsapp1，然后转到www.railsapp2.com，服务器现在返回simpleapp的HTML。只有当我在Apache中禁用railsapp1和railsapp2时，服务器才会正确响应www.railsapp2.com上的请求。

有关为什么会发生这种情况的任何想法？

SimpleApp的VHOST文件：

<VirtualHost *:80> 
    ServerName www.simpleapp.com 
    ServerAlias simpleapp.com 
    DocumentRoot /home/nudecanaltroll/public_html/simpleapp 
</VirtualHost> 

RailsApp1的VHOST文件：

<VirtualHost *:80> 
    ServerName railsapp1.com 
    DocumentRoot /home/nudecanaltroll/public_html/railsapp1/public 
    RewriteEngine On 
    <Proxy balancer://mongrel1> 
    BalancerMember http://127.0.0.1:5000 
    BalancerMember http://127.0.0.1:5001 
    BalancerMember http://127.0.0.1:5002 
    </Proxy> 
    # Timeout in 30 seconds 
    ProxyTimeout 30 
    # Make sure people go to www.railsapp1.com, not railsapp1.com 
    RewriteCond %{HTTP_HOST} ^railsapp1\.com$ [NC] 
    RewriteRule ^(.*)$ http://www.railsapp1.com$1 [R=301,NE,L] 
    # Redirect all non-static requests to thin 
    RewriteCond %{DOCUMENT_ROOT}/%{REQUEST_FILENAME} !-f 
    RewriteRule ^/mongrel1(.*)$ balancer://mongrel1%{REQUEST_URI} [P,QSA,L] 
    # Proxy Stuff 
    ProxyPass/balancer://mongrel1/ 
    ProxyPassReverse/balancer://mongrel1/ 
    ProxyPreserveHost on 
    <Proxy *> 
    Order deny,allow 
    Allow from all 
    </Proxy> 
    # Custom log file locations 
    ErrorLog /home/nudecanaltroll/public_html/railsapp1/log/error.log 
    CustomLog /home/nudecanaltroll/public_html/railsapp1/log/access.log combined 
</VirtualHost> 

RailsApp2的VHOST文件：

<VirtualHost *:80> 
    ServerName railsapp2.com 
    DocumentRoot /home/nudecanaltroll/public_html/railsapp2/public 
    RewriteEngine On 
    <Proxy balancer://mongrel2> 
    BalancerMember http://127.0.0.1:6000 
    BalancerMember http://127.0.0.1:6001 
    BalancerMember http://127.0.0.1:6002 
    </Proxy> 
    # Timeout in 30 seconds 
    ProxyTimeout 30 
    # Make sure people go to www.railsapp2.com, not railsapp2.com 
    RewriteCond %{HTTP_HOST} ^railsapp2\.com$ [NC] 
    RewriteRule ^(.*)$ http://www.railsapp2.com$1 [R=301,NE,L] 
    # Redirect all non-static requests to thin 
    RewriteCond %{DOCUMENT_ROOT}/%{REQUEST_FILENAME} !-f 
    RewriteRule ^/mongrel2(.*)$ balancer://mongrel2%{REQUEST_URI} [P,QSA,L] 
    # Proxy Stuff 
    ProxyPass/balancer://mongrel2/ 
    ProxyPassReverse/balancer://mongrel2/ 
    ProxyPreserveHost on 
    <Proxy *> 
    Order deny,allow 
    Allow from all 
    </Proxy> 
    # Custom log file locations 
    ErrorLog /home/nudecanaltroll/public_html/railsapp2/log/error.log 
    CustomLog /home/nudecanaltroll/public_html/railsapp2/log/access.log combined 
</VirtualHost> 

RailsApp1的mongrel_cluster.yml文件：

--- 
address: 127.0.0.1 
log_file: log/mongrel.log 
port: 5000 
cwd: /home/nudecanaltroll/public_html/railsapp1 
environment: production 
pid_file: /home/nudecanaltroll/public_html/railsapp1/tmp/pids/mongrel.pid 
servers: 3 

RailsApp2的mongrel_cluster.yml文件：

--- 
address: 127.0.0.1 
log_file: log/mongrel.log 
port: 6000 
cwd: /home/nudecanaltroll/public_html/railsapp2 
environment: production 
pid_file: /home/nudecanaltroll/public_html/railsapp2/tmp/pids/mongrel.pid 
servers: 3 

Answer 1

我想通了。由于我不知道的原因，我需要为RailsApp2设置ServerAlias，并添加“www”。在ServerName前面。所以railsapp2.com虚拟主机文件的顶部，现在看起来是这样的：

<VirtualHost *:80> 
    ServerName www.railsapp2.com 
    ServerAlias railsapp2.com 
    ... 

出于某种原因，RailsApp1不需要这些变化才能正常工作。
