Configure mutiple IBM HTTP Server / Other Apache based WEB server on 1 physical server (Section 2)

Continue from the last article......

 

2) Confirmed the 80 port of the new added IP is not listened by any other services.

 

Why need to test this? This is to ensure the 80/443 port of the new created IP is not listened by any other application.

 

Test method: telnet 192.168.67.101 80.

 

OK, the command returned a blank screen, it means the port 80 of 192.168.67.101 have been listened by some application. Then we must find out which application is listen it so that we could release it. 

Windows: netstat -ano | findstr :80

Linux: netstat -ano | grep :80

 

 

Now we know a application with PID: 2836 is listening 0.0.0.0:80, this means all the IP address 80 port will be listened by this application. Let's see which application it is. 

 

Windows: Use Taskmanager. By default, the PID column will not be listed in the task manager, you may use this option to list it out.

 

 

Found! It's httpd.exe, so it is a Apache process, actually I installed IHS, so it's the IHS service that I created.

 

 

Linux: it's simple, just use a command: ps -ef | grep 2836. Here I won't show the command, if you are Linuxer, you will know how to utilize the ps tool.

 

 

So now, our topic become how to release the port 80 of the new virtual IP: 192.168.67.101. 

 

Let's see my configuration file. Here I list a simple httpd.conf file of the IHS:

Please note the RED line, it means my IHS service will listen the port 80 of all the IP on this server. So let's modify it as below:

 

Listen 192.168.67.100:80
<VirtualHost 192.168.67.100:80>

 

And then restart the service (how to restart? will show it later.) Test again:

 

 

Connection failed to the 192.168.67.101 port 80, means 192.168.67.101:80 have been released. Then we could start other steps.
