It seems that MySQL was created to be installed on RHEL/CentOS/Fedora...

But what if you are actually using Ubuntu? Well, this is the purpose of the following tutorial:

  1. Trace all old MySQL installations on the servers (yes, some vendors are delivering baseline images with some old MySQL versions)

    sudo dpkg --get-selections | grep -v deinstall | grep -i mysql
    
    sudo apt-get --purge remove libdbd-mysql-perl libmysqlclient18 mysql-client mysql-client-5.5 mysql-client-core-5.5 mysql-common mysql-server mysql-server-5.5 mysql-server-core-5.5 php5-mysql
  2. Get the MySQL repository

     sudo wget -O mysql.deb http://dev.mysql.com/get/mysql-apt-config_0.2.1-1ubuntu14.04_all.deb
  3. Install the repository

    sudo dpkg -i mysql.deb
    
    sudo apt-get update
  4. Install the mysql package (you may need to select the right version and select a root password)

    sudo apt-get -y install mysql-server mysql-client
  5. If you have a pre-configured my.cnf, get it and replace the current my.cnf file. Then you should restart the MySQL. I would recommend you to keep your my.cnf in a code repository like git to manage the versionssudo apt-get -y install git

    sudo git clone wherever tmp && git mv tmp/.git . && rm -rf tmp
    
    sudo service mysql restart
  6. Now it time to recover your database from your backup (if you have one) and back to business...

Keep Performing,
