How To Install WordPress, Apache, MySQL and PHP on Ubuntu 16.04

In this post I will show, how to install WordPress, Apache, MySQL and PHP on Ubuntu 16.04.

Install Apache:

When you’re done installing Apache2, the below commands allow you to start it up

sudo apt-get update
sudo apt-get install apache2

sudo systemctl start apache2
         OR
sudo service apache2 start

If you you are using Nginx you may get the below ERROR:
Address already in use: AH00072: make_sock: could not bind to address [::]:80
Then GO to /etc/apache2/ports.conf

and change Listen 80 to Listen 8090 using below command

sudo vim  /etc/apache2/ports.conf

open browser and enter http://localhost:8090
The below commands allow you to restart it and enable it to startup everytime you reboot your systems.

sudo systemctl restart apache2
sudo systemctl enable apache2

Install MySQL:

sudo apt-get install mysql-server mysql-client libmysqlclient-dev python3-dev

During MySQL database server installation, you’ll be prompted to create a root password.. This password enables the root users to administer MySQL server.
After installing MySQL database server, the commands below allow you to start it up, restart it and enable it so that it starts up automatically everytime you reboot your servers.

sudo systemctl start mysql
          OR
sudo service mysql start
sudo systemctl restart mysql
sudo systemctl enable mysql

After running the above commands and installing MySQL, run the commands below to configure it.

sudo mysql_secure_installation

When prompted, choose Yes or No accordingly until you’re done.

mysql -u root -p
CREATE DATABASE DBName;
CREATE USER DBName@localhost IDENTIFIED BY 'new_password_here';
GRANT ALL ON DBName.* to DBName@localhost;
FLUSH PRIVILEGES;
exit;

phpinfo();

?>

Use below url to execute the file

Move index.php to begining as shown below
