[cPanel] Internal Server Error after installation
Installing cPanel is very easy, what you need is patience, enough bandwidth and following tutorial described in cPanel Quick Install Guide. But even I have followed the guide carefully and make sure I have make prepation still I can go wrong. Below is quick steps to install cPanel:
- Install Minimal CentOS
- Create harddrive partition
- Deactivate the firewall
- Disable SELinux
- Ensure your newly-installed OS has the latest updates and patches.
- Obtaining a cPanel/WHM License
- Begin Installation
cd /home wget -N http://layer1.cpanel.net/latest sh latest /usr/local/cpanel/cpkeyclt
After 5 hours installation is complete then when I am accessing WHM, this error came up
Internal Server Error
open3: exec of /usr/local/cpanel/whostmgr/bin/whostmgr3 ./initial_setup_wizard1 failed at cpsrvd line 6114
Checking and Googling for about 20 minutes what went wrong, and I saw in forum some people also had this problem and they were suggested to run below command
/scripts/upcp --force
This command will make your cpanel install is updated with latest version by force (replace all file). Detail here.
After running several hours, the script stops and say everything is okay. I went to WHM again and now it working flawlessly
