Open the terminal and follow along:

  • Uninstall any existing version of MySQL
sudo rm /var/lib/mysql/ -R

sudo apt-get remove apparmor

  • Download version 5.5.51 from MySQL site

sudo groupadd mysql

  • Add mysql (not the current user) to mysql user group
sudo useradd -g mysql mysql

  •  Extract it
sudo tar -xvf mysql-5.5.56-linux-glibc2.5-x86_64.tar.gz

  • Move it to /usr/local
sudo mv mysql-5.5.56-linux-glibc2.5-x86_64 /usr/local/

  • Create mysql folder in /usr/local by moving the untarred folder
