Installing of Mysql

Mysql installation is very easy no need to think so much. First, You should know on which platform you want to install mysql. If you want to install on windows OS then don’t worry and don’t think to much(https://dev.mysql.com/doc/refman/5.6/en/windows-installation.html). If you want to install on Linux then you should know your platform support yum repository or apt repository.

Before installing you should know about rpm package or binary package. If you are new to linux or database then you should install binary package. Here i am telling you some steps of installation mysql 5.7 on ubuntu server.

First Check your Ubuntu Server is connected to internet.

Then used these commands given  below

[[email protected] ~] $ sudo apt-get install mysql-community server

After checking the packages it asks with you ( Y or N)

Press Y for installation. Then it installs automatically. You just need to set password for root user.
