Some updates about the apache settings. I have made it work now. Generally it is simple to use apache, but it bites at certain points. ---- it is not the problem of apache; instead, it is from the network environment.

As previously I modified the httpd.conf file and decided to use the default folders. When I test the syntax with "apachectl -t", it returned "Syntax OK". But I couldn't see the page from my Mac. When tried to visit the website from the server itself, it worked! That meant the service was Ok.

Then, I tested the website from Mac on the same LAN. But I failed. That meant the sever refused connection from other computers. I also get some error message from the firefox browser in which it's mentioned that the computer may be protected by firewall. Therefore I checked the /etc/sysconfig/iptables. I found port 80 was not open by default. Then I opened the port 80. Everything worked fine.

I collected some useful webpages, listed below for reference. These links are more helpful to me than previously collected ones.

Performing yum update on system registered with Red Hat Subscription Manager fails with error " Errno 14] PYCURL ERROR 22 - NSS: client certificate not found"

 https://access.redhat.com/solutions/187873

Environment

• Red Hat Enterprise Linux 6.3
• Red Hat Subscription Manager (RHSM)

Resolution

• Run the following commands to refresh certificates on the system with the problem and then try to run yum check-update

# subscription-manager refresh 
# yum check-update

• If the issue persists then try following :
  
• Run the command as mentioned below which removes all of the subscriptions and identity data from the local system, without affecting the consumer information in the subscription service.
  

# subscription-manager clean 

• Now unregister your system with command:

# subscription-manager unregister

• Go to Customer Portal search with hostname of the system in the System tab and note down the UUID
  
• Register your system with following command(using the UUID noted from customer portal):
  

# subscription-manager register --consumerid=<system UUID>

You can also refer # man subscritption-manager for more information.

Root Cause

• The system's local entitlement information was corrupted or lost somehow.
