Installing MySQL Database:

You have successfully installed the Ubuntu 18.04.2 & Apache web server. Now it’s the time to install MySQL database on your server. Follow the below instructions to install the MySQL database. The MySQL is mainly used to store the information provided by the user on the server.

sudo apt install mysql-server

The above command will install the list of packages related to the MySQL and it will consume some space in your server. You need to enter “Y” and hit the “Enter” button.

sudo mysql_secure_installation

Now, you will be asked to configure the “VALIDATE PASSWORD PLUGIN

If you enable this feature, The MySQL will rejects the request from wrong password. So you need to be clear while entering the password and don’t forgot, save it some where else locally. Please enter the strong password.

Enter “Y” and hit the “Enter” button.

VALIDATE PASSWORD PLUGIN can be used to test passwords and improve security. It checks the strength of the password and allows the users to set only those passwords which are secure enough.

Would you like to setup VALIDATE PASSWORD plugin?

Press y|Y for Yes, any other key for No:

Now, you will be asked to enter the password level

LOW Length >= 8
MEDIUM Length >= 8, numeric, mixed case, and special characters
STRONG Length >= 8, numeric, mixed case, special characters, and dictionary file

Please enter 0 = LOW, 1 = MEDIUM and 2 = STRONG: 1

Despite whether you chose a “Validate Password Plugin“, You MySQL server will ask you about confirming the password that you entered. This is the superuser or administrative account and so you will have the increased privileges. Don’t forget to choose the Strong Password to the MySQL login.

Installing PHP on the server:

PHP is playing the essential role in server side compiling the codes. This will process your codes and displays into dynamic content. This PHP has a lot of libraries and so you can able to run large number scripts, codes and more. You can easily connect the MySQL Database with PHP and so you will be able to create dynamic web apps with MySQL database.

Just follow the steps to install the PHP:

sudo apt install php libapache2-mod-php php-mysql

The PHP will install in your server. But before checking it, we need to do more steps to install the PHP in your server.

Usually, Apache will look for a file “index.html”. Here we need to change the file as “index.php”, so the Apache will look for “PHP” files in your server. We are not removing the file but changing the priority of the file extension. Due to this, Apache will look for index.php initially, if the file wasn’t present the Apache will look for index.html one.

To do this, follow the below command:

sudo nano /etc/apache2/mods-enabled/dir.conf

The above code will help you to edit the Apache Directory with super user previliges.

The output will look like this:

<IfModule mod_dir.c>
DirectoryIndex index.html index.cgi index.pl index.php index.xhtml index.htm
</IfModule>

Just change the exntension from “index.html to index.php” in the first and change the “index.php to index.html” in the fourth one. After changing, it will look like the below one:

<IfModule mod_dir.c>
DirectoryIndex index.php index.html index.cgi index.pl index.xhtml index.htm
</IfModule>

Now, Apache will look for the Index.php file. Don’t forget to save the file.

Now you should need to restart the Apache server to update the changes that you had done. Follow the below command to restart the Apache Server.

sudo systemctl restart apache2

If done anything wrong in editing the directory, the Apache will throw you the error and it will not start. You can check the status of the Apache server by entering the below command.

sudo systemctl status apache2

Now, the status of the Apache in your server will appear on your screen. We added the sample output for your clarification.

Sample Output:

● apache2.service – LSB: Apache2 web server
Loaded: loaded (/etc/init.d/apache2; bad; vendor preset: enabled)

├─13628 /usr/sbin/apache2 -k start
├─13629 /usr/sbin/apache2 -k start
└─13630 /usr/sbin/apache2 -k start

Enter “Q” to exit this status screen. If you get the above sample output on your screen then you have sucessfully configured the Apache server with PHP.

Now you need to install the PHP clients, “CURL” is one the best PHP client. It is mainly used to sending and receiving the request from the server.

sudo apt install php-cli

A list of packages will appear on the screen, from this you need to select the package and install it on your server.

sudo apt install package_name

That’s it, You have successfully installed the LAMP Stack on your Web server. Before making any changes, we request you to take a backup of your server. Now it is just to check the PHP on your web server.

Testing the PHP & Apache on your server:

“Php Info” is the basic method to verify the PHP & Apache functioning on the web server. Creating a simple script will show you the complete details of your servers PHP version & Apache server details.

To create the dynamic web app files in Ubuntu 18.04.2, You just need to access the “Web Root” folder. Which is presented in “/home/s1/html/” location.

sudo nano /home/s1/html/info.php

The above code will create a new file inside the root folder and now copy the below code and paste in your server console.

info.php

<?php
phpinfo();
?>

After pasting the codes, save and quit.

To verify your server, you need to open the below URL in your browser.

http://ip_address_of_your_server/info.php

Note: Replace “ip_address_of_your_server” with your server IP Address

Now, in the browser, you will be able to see the below images that appear on your screen.

php verify

If the above image appears on the screen, Then the PHP and Apache are successfully installed in your web server. You can start importing your dynamic web apps into the root folder through the FTP and don’t forget to delete the PHP info page.

You can delete the PHP info page by entering the below command,

sudo rm /home/s1/html/info.php
