如何在apache服务器中运行nodejs应用程序

Question

我想在apache服务器上通过子域运行我的nodejs应用程序.我在cpanel中创建了主域的子域.我的项目有3个以上的子域和所有子域指向不同的nodejs应用程序.子域将我重定向到适当的文件夹,但是当我在浏览器中通过子域运行应用程序时,它不会在apache服务器上运行节点应用程序.它仅显示项目的文件夹列表.

我参考以下链接以供参考.

在apache中运行Node.js？

项目目录:

/家庭/ ABC /的public_html /节点

我的主要域名是:

https://www.example.com

我在cpanel中创建了子域:

https://www.node.example.com

我在浏览器中访问子域:

node.example.com

我在softlayer服务器上部署了我的应用程序.

以下是apache配置:

档案:

/usr/local/apache/conf/includes/abc_node.conf

组态:

<VirtualHost 132.159.25.21:80>
   ServerAdmin info@example.com
   ServerName node.example.com
   ServerAlias www.node.example.com

   DocumentRoot /home/abc/public_html
   <Directory /home/abc/public_html/node>
      Options -Indexes +FollowSymLinks
      AllowOverride None
      Require all granted
   </Directory>

   ProxyRequests Off
   ProxyPreserveHost On
   ProxyVia Full
   <Proxy *>
      Require all granted
   </Proxy>

   <Location /node>
      ProxyPass http://132.159.25.21:8080
      ProxyPassReverse http://132.159.25.21:8080
   </Location>

   ErrorLog /home/abc/public_html/node/error.log

   # Possible values include: debug, info, notice, warn, error, crit,
   # alert, emerg.
   LogLevel warn

   CustomLog /home/abc/public_html/node/access.log combined

</VirtualHost>

我使用以下ip和port运行我的节点js应用程序

132.159.25.21:3030

我以下列方式在nodejs应用程序中定义了我的端口

var port = parseInt(process.env.PORT,3030)|| 8080;

引用此错误:AH00548:NameVirtualHost无效,将在下一个版本/usr/local/apache/conf/httpd.conf:445中删除代码.NameVirtualHost 132.159.25.21:80

我把may vhosts文件放在/usr/local/apache/conf/httpd.conf文件的末尾,因为在文件中他们写了一个警告"#DO NOT EDIT.自动生成.如果你需要改变请使用包括文件."

我需要帮助才能解决此问题.如果您需要进一步了解申请,请告知我们.

配置看起来正确,除了一位,/ node位置路径应该具有正确的反向代理的目标匹配斜线,而不会产生意外后果:

为了清晰起见,我宁愿这样定义它:

ProxyPass /node/ http://132.159.25.21:8080/
ProxyPassReverse /node/ http://132.159.25.21:8080/

考虑到使用目标的代理http://132.159.25.21:8080是不正确的,并且它应该始终定义为http://132.159.25.21:8080/,因此源应该以相同的方式匹配斜杠,因此/ node /是正确的方法.

至于"NameVirtualHost"警告.它只是告诉你,在Apache HTTPD的2.4.X版本中不再需要它,因为该指令仅需要2.2,2.4"智能"检测命名的虚拟主机.

SideNote:<Proxy *>没有效果,所以定义它是徒劳的.Proxy*用于转发代理,显然您不需要它,并且已关闭ProxyRequests禁用此类功能.所以也删除那个.

---由于您的意见,答案延期:

要访问您的节点,您必须访问:

http://node.example.com/node/

或添加一个"默认"重定向,将您带到它.如:

RedirectMatch ^/$ /node/

您通过访问node.example.com获取索引(文件列表),因为-Indexes是为子目录定义的,意味着前一个子目录已启用索引,因此定义:

<Directory /home/abc/public_html>
    Options -Indexes +FollowSymLinks
    ....

而不是定义/ home/abc/public_html/node,这不适用于这种情况,因为node /不是目录,而是后端中的虚拟路径,因此对于校正抖动,它永远不应该包含在Directory路径中.

如果您只想在访问http://node.example.com/时访问后端,只需使用此代替ProxyPass/node /:

ProxyPass / http://132.159.25.21:8080/
ProxyPassReverse / http://132.159.25.21:8080/
