Install php in ubuntu:

About the LAMP configuration steps under Ubuntu:

First, install LAMP, which is Apache, PHP5, Mysql5.

Open the terminal and enter the command line.

1. Install Apache

1. Open the terminal

2. Enter the following command

sudo apt-get install apache2

3. If you do not have sudo permissions, you need to enter a password.

2. Test Apache

To determine whether the installation was successful, test it.

1. Open the browser and enter the following URL

http://localhost/

If successful, you will see the following content "It works!" Congratulations, you have taken the first step.

3. Install PHP5

Step 1. Open the terminal (ctrl alt T).

Step 2. Enter the following command line:

sudo apt-get install php5 libapache2-mod-php5

Step 3 .In order for PHP and Apache to work together, you need to configure PHP and test it.

sudo /etc/init.d/apache2 restart

4. Test PHP

Step 1. First create a PHP test file (we call it phptest.php) and enter the following content:

sudo gedit /var/www/testphp.php

Step 2. This A text editor will open, enter the following content in it.

<?php phpinfo(); ?>

Step 3. Save and exit.

Step 4. Now open the browser and view the content you just created. Enter the following URL.

http://localhost/testphp.php

If the PHP information page is displayed, it means you have taken another small step towards success.

5. Install MySQL

Let’s install Mysql5 below (This is the last step and the more troublesome step, so pay attention when installing.)

Step 1. Again Open a terminal and enter the following.

sudo apt-get install mysql-server

Step 2. During installation, if you are asked to enter the Mysql password, enter the password. If there is no requirement, proceed to the next step. Enter the following command in the terminal.

mysql -u root

Later, you have to enter the following;

mysql> SET PASSWORD FOR 'root'@'localhost' = PASSWORD('yourpassword');

The 'root' above is your Mysql username, and 'yourpassword' is your new password.

Step 3. Next we will deal with the more difficult phpmyadmin. A common problem here is that phpmyadmin is obviously installed but when entering http://localhost/phpmyadmin, the management interface does not appear. Instead, there is no Page found. Don't worry, install phpmyadmin first and then solve it. Enter the following command:

sudo apt-get install libapache2-mod-auth-mysql php5-mysql phpmyadmin

The phpmyadmin here is compatible with the previously installed php5. If the PHP you installed does not match phpmyadmin, they will not work.

Step 4. Now let’s solve the problem of phpmyadmin “not working”. When we install phpmyadmin, don’t think that everything is ready. In fact, there is still one more work to be done, which is to configure phpmyadmin and apache2. In the same terminal, enter:

cp /etc/phpmyadmin/apache.conf /etc/apache2/sites-available/phpmyadmin

This will copy apache.conf (apache configuration file) in phpmyadmin to the phpmyadmin file under apache2/sites-available.

Step 5. Then enter and enter the sites-enabled folder:

cd /etc/apache2/sites-enabled/

Step 6. After entering, create a link to the configuration file so that you can use it. Enter:

sudo ln -s ../sites-available/phpmyadmin

Step 7. Restart apache2

sudo /etc/init.d/apache2 restart

Finally, open http://localhost/phpmyadmin to experience it
