How to Install LAMP Stack on Ubuntu 18.04 Server/Desktop
This tutorial is going to show you how to install LAMP stack on Ubuntu 18.04 LTS. A software stack is a set of software tools bundled together. LAMP stands for Linux, Apache, MariaDB/MySQL and PHP, all of which are open source and free to use. It is the most common software stack that powers dynamic websites and web applications. Linux is the operating system; Apache is the web server; MariaDB/MySQL is the database server and PHP is the server-side scripting language responsible for generating dynamic web pages.
To follow this tutorial, you need an Ubuntu 18.04 OS running on your local computer or on a remote server. If you are looking for a VPS (Virtual Private Server), then you can click this special link to get $100 free credit on DigitalOcean. (For new users only). If you are already a DigitalOcean user, then you can click this special link to get $50 free credit on Vultr (for new users only).
Step 1: Update Software Packages
Before we install the LAMP stack, it’s a good idea to update repository and software packages. Run the following command on your Ubuntu 18.04 OS.
sudo apt update sudo apt upgrade
Step 2: Install Apache Web Server
Enter the following command to install Apache Web server. The
apache2-utils package will install some useful utilities like Apache HTTP server benchmarking tool (ab).
sudo apt install -y apache2 apache2-utils
After it’s installed, Apache should be automatically started. Check its status with
systemctl status apache2
● apache2.service - The Apache HTTP Server Loaded: loaded (/lib/systemd/system/apache2.service; enabled; vendor preset: enabled) Drop-In: /lib/systemd/system/apache2.service.d └─apache2-systemd.conf Active: active (running) since Sat 2018-09-08 10:46:05 UTC; 3min 37s ago Main PID: 1610 (apache2) Tasks: 55 (limit: 505) CGroup: /system.slice/apache2.service ├─1610 /usr/sbin/apache2 -k start ├─1612 /usr/sbin/apache2 -k start └─1613 /usr/sbin/apache2 -k start
If it’s not running, use systemctl to start it.
sudo systemctl start apache2
It’s also a good idea to enable Apache to automatically start at system boot time.
sudo systemctl enable apache2
Check Apache version:
Server version: Apache/2.4.29 (Ubuntu) Server built: 2018-06-27T17:05:04
Now type in the public IP address of your Ubuntu 18.04 server in the browser address bar. You should see the “It works!” Web page, which means Apache Web server is running properly. If you are installing LAMP on your local Ubuntu 18.04 computer, then type
localhost in the browser address bar.
If the connection is refused or failed to complete, there might be a firewall preventing incoming requests to TCP port 80. If you are using iptables firewall, then you need to run the following command to open TCP port 80.
sudo iptables -I INPUT -p tcp --dport 80 -j ACCEPT
If you are using UFW firewall, then run this command to open TCP port 80.
sudo ufw allow http
Now we need to set
www-data (Apache user) as the owner of document root (otherwise known as web root). By default it’s owned by the root user.
sudo chown www-data:www-data /var/www/html/ -R
Step 3: Install MariaDB Database Server
MariaDB is a drop-in replacement for MySQL. Enter the following command to install it on Ubuntu 18.04.
sudo apt install mariadb-server mariadb-client
After it’s installed, MariaDB server should be automatically stared. Use systemctl to check its status.
systemctl status mariadb
● mariadb.service - MariaDB 10.1.34 database server Loaded: loaded (/lib/systemd/system/mariadb.service; enabled; vendor preset: enabled) Active: active (running) since Sat 2018-09-08 11:13:27 UTC; 21s ago Docs: man:mysqld(8) https://mariadb.com/kb/en/library/systemd/ Main PID: 3473 (mysqld) Status: "Taking your SQL requests now..." Tasks: 27 (limit: 505) CGroup: /system.slice/mariadb.service └─3473 /usr/sbin/mysqld
If it’s not running, start it with this command:
sudo systemctl start mariadb
To enable MariaDB to automatically start at system boot time, run
sudo systemctl enable mariadb
Now run the post installation security script.
When it asks you to enter MariaDB root password, press Enter key as the root password isn’t set yet. Then enter
y to set the root password for MariaDB server.
Next, you can press Enter to answer all remaining questions, which will remove anonymous user, disable remote root login and remove test database. This step is a basic requirement for MariaDB database security. (Note that the letter
Y is capitalized, which means it’s the default answer.)
By default, the MaraiDB package on Ubuntu uses unix_socket to authenticate user login, which basically means you can use username and password of the OS to log into MariaDB console. So you can run the following command to login without providing MariaDB root password.
sudo mariadb -u root
To exit, run
Check MariaDB server version information.
mariadb Ver 15.1 Distrib 10.1.34-MariaDB, for debian-linux-gnu (x86_64) using readline 5.2
Step 4: Install PHP7.2
At the the time of this writing, PHP7.2 is the latest stable version of PHP and has a minor performance edge over PHP7.1. Enter the following command to install PHP7.2.
sudo apt install php7.2 libapache2-mod-php7.2 php7.2-mysql php-common php7.2-cli php7.2-common php7.2-json php7.2-opcache php7.2-readline
Enable the Apache php7.2 module then restart Apache Web server.
sudo a2enmod php7.2 sudo systemctl restart apache2
Check PHP version information.
PHP 7.2.7-0ubuntu0.18.04.2 (cli) (built: Jul 4 2018 16:55:24) ( NTS ) Copyright (c) 1997-2018 The PHP Group Zend Engine v3.2.0, Copyright (c) 1998-2018 Zend Technologies with Zend OPcache v7.2.7-0ubuntu0.18.04.2, Copyright (c) 1999-2018, by Zend Technologies
To test PHP scripts with Apache server, we need to create a
info.php file in the document root directory.
sudo nano /var/www/html/info.php
Paste the following PHP code into the file.
<?php phpinfo(); ?>
To save a file in Nano text editor, press
Ctrl+O, then press Enter to confirm. To exit, press
Ctrl+X. Now in the browser address bar, enter
sever-ip-address with your actual IP. If you follow this tutorial on your local computer, then type
You should see your server’s PHP information. This means PHP scripts can run properly with Apache web server.
How to Run PHP-FPM with Apache
There are basically two ways to run PHP code with Apache web server:
- Apache PHP module
In the above steps, the PHP7.2 module is used to handle PHP code, which is usually fine. But in some cases, you need to run PHP code with PHP-FPM instead. Here’s how.
Disable the Apache PHP7.2 module.
sudo a2dismod php7.2
sudo apt install php7.2-fpm
sudo a2enmod proxy_fcgi setenvif
/etc/apache2/conf-available/php7.2-fpm.conf configuration file.
sudo a2enconf php7.2-fpm
Restart Apache for the changes to take effect.
sudo systemctl restart apache2
Now if you refresh the
info.php page in your browser, you will find that Server API is changed to
FPM/FastCGI, which means Apache web server will pass PHP requests to PHP-FPM.
Congrats! You have successfully installed LAMP stack (Apache, MariaDB and PHP7.2) on Ubuntu 18.04. For your server’s security, you should delete
info.php file now to prevent prying eyes.
sudo rm /var/www/html/info.php

MariaDB Installed Without Password Prompts For Root On Ubuntu 17.10 / 18.04
Recently I was testing MariaDB database server on Ubuntu 17.10 / 18.04 and discovered that MariaDB database server now installs on Ubuntu without prompting the root user for password to access the server.
Is this new?
It’s always been the case where MySQL and MariaDB, a fork of MySQL prompt for passwords everytime before access is granted to the server. Apparently, not anymore for MariaDB. Now simply installing the database gives the root access without password.
Even after running the command sudo mysql_secure_installation… the root account password is never required. However, other applications and services that depend on MariaDB will fail if the root password is needed for authentication.
phpMyAdmin and MySQL Workbench database may fail if MariaDB is setup this way.
This brief tutorial is going to show students and new users how to set a root password for MariaDB and allow password authentication.
After digging a bit, I discovered that MariaDB uses unix_socket plugin to authenticate… and not passwords. Even if you set a password, it is ignored. To re-enable password authentication, follow the steps below:
Logon to MariaDB server by running the commands below
sudo mysql -u root
Notice no password?
That should get you into the database server. After that, run the commands below to disable plugin authentication for the root user
use mysql; update user set plugin='' where User='root'; flush privileges; exit
Restart and run the commands below to set a new password.
sudo systemctl restart mariadb.service
After that, run the commands below to secure MariaDB server and create a new root password.
When prompted, answer the questions below by following the guide.
- Enter current password for root (enter for none): Just press Enter
- Set root password? [Y/n]: Y
- New password: Enter password
- Re-enter new password: Repeat 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
You should now be able to logon with password authentication.. and other applications should now work with the root password authentication.
The next time type the commands below to logon
sudo mysql -u root -p
Then type the password to sign on
