How to run nodejs application in apache server

问题:

I would like to run my nodejs application via subdomain on apache server. I created subdomain of primary domain in cpanel. My project having more than 3 subdomains and all subdomains points different nodejs application. Subdomain redirects me in proper folder but when I run an application via subdomain in browser, it does not run node application on apache server. It displays folder lists of project only.

I refer following link for reference.

Running Node.js in apache?

Project Directory :

/home/abc/public_html/node

My primary domain is :

https://www.example.com

I created sub-domain in cpanel :

https://www.node.example.com

I access sub-domain in browser :

node.example.com

I deployed my application on softlayer server.

Following is apache configuration:

File :

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

Configuration:

<VirtualHost 132.159.25.21:80>
   ServerAdmin [e-mail]
   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>

I run my node js application using following ip and port

132.159.25.21:3030

I defined my port in nodejs application in following way

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

With the reference of this error : AH00548: NameVirtualHost has no effect and will be removed in the next release /usr/local/apache/conf/httpd.conf:445 following code has been written. NameVirtualHost 132.159.25.21:80

I put may vhosts file at the end of /usr/local/apache/conf/httpd.conf file, becuase in file they wrote a warning of "# DO NOT EDIT. AUTOMATICALLY GENERATED. IF YOU NEED TO MAKE A CHANGE PLEASE USE THE INCLUDE FILES."

I required help to resolve this issue. Please let me know if you required further more to know about application.

回答1:

The configuration looks correct except for one bit, the /node location path should have the target matching slashes for reverse proxying correctly without unexpected consequences:

I'd rather define it like this for clarity's shake:

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

Take into account while Proxying using the target http://132.159.25.21:8080 is incorrect, and it should always defined as http://132.159.25.21:8080/ and therefore the source should match slashes in the same fashion, therefore /node/ is the correct way.

As for "NameVirtualHost" warning. It's just telling you, that it is not needed any longer in 2.4.X version of Apache HTTPD since that directive is only needed for 2.2, 2.4 got "smarter" detecting named virtualhosts.

SideNote: <Proxy *> has no effect, so defining it is futile. Proxy * is used for forward proxying and clearly you do not want it and have disabled such functionality with ProxyRequests off. So remove that one also.

--- Answer extension due to your comments:

To reach your node you would have to access:

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

or add a "default" redirection that takes you to it.Such as:

RedirectMatch ^/$ /node/

You are getting indexes (file list) by accessing node.example.com because -Indexes is defined for a subdirectory, meaning previous one has Indexes enabled, So define:

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

Instead of defining /home/abc/public_html/node, which does not apply to this case, since node/ is not a directory, but a virtual path in a backend, so for correction shake it should never be included in a Directory path.

If you just want to access the backend while accessing http://node.example.com/ Just use this instead of ProxyPass /node/:

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