How To Install LAMP Stack on Oracle Linux 9

LAMP is an acronym for Linux, Apache, MySQL and PHP, which are open-source software that work together to build powerful web applications. In this case, Linux is the operating system being used. Apache (httpd in Redhat operating systems) is the web server while MySQL is a database management application. PHP (Hypertext Pre-processor) is the backend programming language. In this guide, we are going to look at how to install Apache, MySQL and PHP (LAMP stack) on Oracle Linux 9.

Step 1: Install Apache Web server

Httpd is already available in the official repository of Oracle Linux 9. We are going to install it with dnf command as shown.

sudo dnf -y install httpd

Now start httpd service and enable it to start on system boot.

sudo systemctl start httpd
sudo systemctl enable httpd
sudo systemctl status httpd

We need to open port 80 on the firewall since we will configure our web application to run on that port.

sudo firewall-cmd --permanent --add-service={http,https}
sudo firewall-cmd --reload

Verify Apache web server successful installation from your browser. On your browser, type http://<your-server-ip>. You should be able to open Apache default page as shown:

Step 2: Install PHP on Oracle Linux 9

Just like httpd, PHP is included in Oracle Linux 9 official repository and this makes it easy for us to install. Also install the below shown php modules. Please note that the below command will install php 8.0 which is currently available on Oracle Linux 9.

sudo dnf -y install php php-fpm php-mysqlnd php-opcache php-gd php-xml php-mbstring

By default, Oracle Linux 9 uses php-fpm instead of mod_php. We need to start php-fpm and enable it on system boot.

sudo systemctl start php-fpm
sudo systemctl enable php-fpm

Verify that php-fpm is running by checking on its status.

sudo systemctl status php-fpm

The output should be as shown:

Now restart httpd to use php.

sudo systemctl restart httpd

We also need to test php on the browser. Create a file called info.php in /var/www/html

sudo vim /var/www/html/info.php

Put the below content and save the file.

<?php
phpinfo();
?>

After saving, restart httpd:

sudo systemctl restart httpd

Now on your browser, open http://<your-server-ip>/info.php.

Step 3: Install MariaDB server on Oracle Linux 9

The other component of LAMP is MariaDB which is used for managing web application databases. Run the command below to install it on Oracle Linux 9:

sudo dnf -y install mariadb mariadb-server

Once installed, start MariaDB and enable it to start on system reboot.

sudo systemctl start mariadb
sudo systemctl enable mariadb

Now secure MariaDB and set root password by running the below command:

sudo mariadb-secure-installation

You will be prompted to enter root password if you have one or just press Enter and go ahead to set new root password as well as other parameters as below:

Enter current password for root (enter for none): Just press Enter
Set root password? [Y/n] Y 
New password:  New-root-password
Re-enter new password: Re-enter New-root-password
Remove anonymous users? [Y/n] Y 
Disallow root login remotely? [Y/n] Y 
Remove test database and access to it? [Y/n] Y 
Reload privilege tables now? [Y/n] Y 
Thanks for using MariaDB!

You can go ahead to configure a database for our application and set a database user. Connect to myariadb by running the below command:

mariadb -u root -p

Provide the root password that you set above. Once connected run the commands below:

CREATE DATABASE mydb;
CREATE USER 'mydbuser'@'localhost' IDENTIFIED BY 'StrongP@asswd';
GRANT ALL PRIVILEGES ON mydb.* TO 'mydbuser'@'localhost';
FLUSH PRIVILEGES;
EXIT;

Step 4: Create Apache virtual host for your site

Using your preferred editor, create a virtual host for your site as shown below:

sudo vim /etc/httpd/conf.d/yourdomain.conf

Add the following content:

<VirtualHost *:80>
    ServerName www.yourdomain.com
    ServerAlias yourdomain.com
    DocumentRoot /var/www/yourdomain
    ErrorLog /var/www/yourdomain/error.log
    CustomLog /var/www/yourdomain/requests.log combined
</VirtualHost>

Now let’s create a demo web page:

sudo mkdir /var/www/yourdomain
sudo vim /var/www/yourdomain/index.html

Add the following contents:

<html>
  <head>
    <title>This is a test page</title>
  </head>
  <body>
    <h2>Hello, It actually works!</h2>
  </body>
</html>

Save the file and let Apache own the root directory then restart httpd:

sudo chown -R apache:apache /var/www/*
sudo touch /var/www/cloudspinz/error.log /var/www/cloudspinz/requests.log
sudo chmod -R 755 /var/www/*
sudo systemctl restart httpd

Configure SELinux

You need to configure SELinux policy to allow Apache access to your domain error files. Run the commands below to set SELinux policy permanently using semanage:

sudo semanage fcontext -a -t httpd_sys_rw_content_t "/var/www/yourdmain(/.*)?"
sudo restorecon -Rv /var/www/yourdomain

Now open your demo web page on the browser to confirm that your virtual host is working properly. If well set, you should see the content from your demo html file.

That’s it. You have successfully installed LAMP stack on Oracle Linux 8 and configured Virtual Host. Enjoy! Do not forget to check more Linux guides below:
