How to install MySQL 5.6 on Ubuntu 14.04
Ubuntu 14.04 comes preloaded with MySQL 5.5 and MySQL 5.6 but by default uses MySQL 5.5. However, you can upgrade to MySQL 5.6 by following the same step i used for my server , hosted at digital ocean.
So far i have not encountered any problem, i also converted my database engine from Myisam to InnoDB without any errors. so lets begin.
Step 1 – Backup, Backup!
Before we begin, lets take backup of our existing databases in case of “Had i known”. Create a folder anywhere you want then login to terminal or putty and issue this command.
Step 2 – Remove old MySQL
I recommend using ‘apt-get purge’ rather than using ‘apt-get remove’ to uninstall the old MySQL server. Don’t worry, this doesn’t mean all your data in /var/lib/mysql will be deleted.
The purge command will remove all the configuration files in /etc/mysql/ . we are doing this because some old MySQL configurations are not supported in MySQL 5.6.
Step 3 – Install MySQL 5.6
Now its time to install MySQL5.6, by running the following command in terminal or putty, remember to add sudo at the beginning if you are using another user instead of root user
Please note during the installation process you will be asked to set up a new password for the root user. if everything goes well you have successfully upgraded your MySQL server from 5.5 to 5.6.
to check your MySQL installed version on your Ubuntu 14.04 run the following:
To restart the mysql service
To start mysql Service
To stop mysql service
To get status of mysql service
