[CentOS]Installing mysql-server

Lets talk about how to install mysql-server on CentOS. I wanted to install it and following describes the steps I have followed. 

sudo yum install mysql-server

But it gave an error :(

Loaded plugins: fastestmirror, refresh-packagekit, security

Loading mirror speeds from cached hostfile

Error: Cannot retrieve metalink for repository: epel. Please verify its path and try again

I didn't give up. I have checked the reasons for why I was getting that particulate error and found out that, it was because outdated certificate. So I used the command for upgrading the certificate. 

sudo yum upgrade ca-certificates --disablerepo=epel

And tried the previous command for installing again and it worked. :) I checked it by starting the mysql service like this.

sudo service mysqld start

Cheers!
