LAMP stack

LAMP is an acronym for Linux, Apache, MySQL, and PHP stack, it is a popular software stack for serving websites.

It is comprised of a Linux server operating system running the Apache2 web server, MySQL database, and the PHP scripting language.

This tutorial was made using Ubuntu 22.04, you must provision a vps have a domain name and configure dns settings as per your vps provider and domain registrars instruction.

SSH into your vps and set a root password.

ssh root@127.0.0.1 use the ip-address provided by your vps provider.

passwd set strong password.

Set up a non-root user account

adduser "new_user"

Now give the new user sudo privileges.

usermod -aG sudo "new_user"

Lets transfer our ssh-keys to our new user.

rsync --archive --chown="new-user":"new-user" ~/.ssh /home/"new_user"

Set up the firewall

sudo ufw allow OpenSSH

sudo ufw enable

Lets go ahead and update the server now.

apt update; apt dist-upgrade -y; apt autoremove -y

Once the server is updated lets edit the sshd_config file to dissallow remote root access to our server and use our non root user to log in from now on.

vim /etc/ssh/sshd_config we want to change PermitRootLogin no to yes, make sure PubkeyAuthentication is set to yes, that PasswordAuthentication is set to no, and that KbdInteractiveAuthentication is no.

We need to reload sshd.

systemctl reload sshd

Now we should reboot the server, when it comes back up you will need to ssh using the non-root user name that we just created.
SSH back into your vps using your non-root user account.

ssh "vps_user"@127.0.0.1" Of course replacing "vps_user" with your non-root user account and 127.0.0.1 with the acutual ip-address of your server.

Now we are going to install our webserver and database server we are using apache2 for our webserver and mariadb for our database.

sudo apt install apache2 mariadb-server -y

We need to let apache2 through our firewall for now on port 80

sudo ufw allow 'Apache' we will remove the allow 'Apache' rule and add the 'Apache Full' rule to enable https traffic later but for now lets just let in http.

After installing apache2 and mariadb we need to enable and strart them.

sudo systemctl enable apache2

sudo systemctl start apache2

sudo systemctl enable mysql

sudo systemctl start mysql

Run the mysql_secure_installation script and follow the instructions

sudo mysql_secure_installation

Now we will install php.

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

Now that PHP is installed lets create the document root of our web server, and give the directory the right permissions.

sudo mkdir /var/www/"my_domain_name.com"

sudo chmod -R 755 /var/www/"my_domain_name.com"

Now we will create our index.html file.

sudo vim /var/www/"my_domain_name.com"/index.html
