Upgrade MySQL on EC2 instance

I upgraded MySQL from 5.5 to 5.7 on an EC2 instance using the following commands:

Stop the server first.

service mysqld stop

Don't forget to backup your DB before the upgrade!

 cp /var/lib/mysql /var/lib/mysql.original


yum remove mysql55-server
yum install mysql57-server
/etc/init.d/mysqld start
