So, all these tools will be under the LAMP stack. Hence, you can easily install it through the command line.

However, it is most important to install every software in a order to work properly. But, don’t worry, I will be guiding you step by step here.

After completing the above steps, you will be able to run the localhost in the browser. Just hit the http://localhost in the URL and you will have the default page of Apache2 as showing below.

In the next step, we will install the MySQL database management. So, just start it.

It will install the latest version of MySQL.

It is not mandatory to create the root user password. Here, if you will create the password of MySQL root user, then keep remind the default user in Linux is root. And the default user of MySQL database is also root.

After installing the MySQL, you may enter into the MySQL database by using the below command.

sudo mysql

If you have set the password for the MySQL user then it will ask for the password.

sudo mysql -p

In case, if you have multiple user in MySQL database then you will have to put the specific username and password to enter into that.

sudo mysql -u root -p
