Complications faced by CPanel users

If you are using CPanel, you are likely to face perl dependency issues when installing git. To install git in this case, follow this procedure:

1. vim /etc/yum.conf, remove perl* from exclude list and save the file
2. yum install git -y
3. vim /etc/yum.conf, add perl* back to exclude list and save the file
