Learn how to install LAMP stack on Docker with this step-by-step guide. Set up Linux, Apache, MySQL, and PHP in isolated containers for efficient and scalable web development. Perfect for beginners and advanced users. #centlinux #linux #docker
The LAMP stack is a popular set of open-source software used together to create dynamic websites and web applications. LAMP stands for:
The LAMP stack’s combination of Linux, Apache, MySQL, and PHP offers a powerful and versatile environment for web development, making it a popular choice among developers worldwide.
We are already learned how to install LAMP stack on Ubuntu. But this is now the era of DevOps and it is necessary to explore how to install LAMP Stack on Docker.
If you are new to Docker platform, then you should read Docker in Action (PAID LINK) by Manning Publications.
There are several alternatives to the traditional LAMP stack, each offering different combinations of technologies to suit various needs and preferences in web development. Here are some popular alternatives:
Each of these alternatives offers different advantages, depending on the specific requirements of the project, such as the need for performance, scalability, ease of development, or the preference for certain programming languages or databases.

We are using a Linux based Docker host with following specification.
Although there are many pre-build single LAMP images are available on Docker Hub. But by following the best practice and to maintain the modularity of the software stack, we will run each service in its relevant container.

Connect with Docker host (docker-01.centlinux.com) as a privileged user by using a ssh tool.
Create a directory to store files related to our LAMP Server.
$ mkdir ~/lamp-server $ cd ~/lamp-server/
Create a directory that will be mounted as Apache Document Root within the Apache container. This directory is used to deploy our web applications and the php-apache Docker container will serve our web applications to clients.
$ mkdir ~/lamp-server/html
Create a default PHP page in this directory. The PHP script contains a single phpinfo() function, that generates a webpage with detailed information about Apache server and installed plugins.
$ echo "<?php phpinfo(); ?>" > ~/lamp-server/html/index.php
We need to install some additional PHP plugins on the php-apache Docker container. For this purpose, we have to create the build context file for our php-apache Docker container.
Create a directory to store php-apache build context.
$ mkdir php-apache
Create build context file for php-apache Docker container.
$ vi php-apache/Dockerfile
Add following directives there in.
FROM php:7.4-apache RUN docker-php-ext-install pdo pdo_mysql mysqli
Since, we are deploying a multi-container Docker application, therefore, we need to use docker-compose to create and execute our containers.
For this purpose, we need to create docker-compose.yml file that contains the directives to create our containers.
$ vi docker-compose.yml
And add following directives to create php-apache container.
version: '3' services: php-apache: build: context: ./php-apache ports: - 80:80 volumes: - ./html:/var/www/html links: - 'mariadb'
Create a directory for Dockerfile that will be used to create mariadb Docker container.
$ mkdir -p mariadb/sql
Create a SQL script to prepare our sample table.
$ vi mariadb/sql/init-db.sql
Add following SQL statements in this file.
USE testdb; CREATE TABLE test ( name varchar(30), email varchar(50) ); INSERT INTO test (name, email) VALUES ('Ahmer', 'ahmer@centlinux.com'), ('Mansoor','mansoor@centlinux.com'), ('Salman','salman@centlinux.com');
Create a Dockerfile to customize our mariadb Docker container.
$ vi mariadb/Dockerfile
Add the following build context there in.
FROM mariadb:10.5 ENV MYSQL_ROOT_PASSWORD 123 ENV MYSQL_USER ahmer ENV MYSQL_PASSWORD 123 ENV MYSQL_DATABASE testdb COPY ./sql /docker-entrypoint-initdb.d/
Create a directory on Docker Host to store MariaDB Server data files. This directory will be mounted within the MariaDB Docker container on startup.
$ mkdir mariadb_data
Now, configure a MariaDB docker container in the same docker-compose.yml file.
$ vi docker-compose.yml
Append following lines of code under the “services” section in this file.
mariadb: build: context: ./mariadb volumes: - ./mariadb_data:/var/lib/mysql
Start our LAMP stack environment by using docker-compose command.
$ sudo docker-compose up ... Starting lamp-server_mariadb_1 ... done Starting lamp-server_php-apache_1 ... done Attaching to lamp-server_mariadb_1, lamp-server_php-apache_1 ... mariadb_1 | 2020-02-28 17:46:24 0 [Note] InnoDB: Buffer pool(s) load completed at 200228 17:46:24
Open URL http://docker-01.centlinux.com in a web browser.
Our LAMP Stack has been serving the default PHP page that we have created above.
To demonstrate the connectivity between php-apache and mariadb Docker containers, we are creating a PHP webpage that creates connection to MariaDB database to fetch and display the data from a database table.
For this purpose, we are replacing the existing index.php with a new webpage that contains the PHP code to accomplish the required task..
$ mv html/index.php html/phpinfo.php $ vi html/index.php
Add following HTML code in this file.
<html> <head> <title>Fetching Data from MariaDB Server</title> </head> <body> <style> td,th { border: solid black 1px; font-size: 30px; width: 200px; } </style> <table> <tr> <th>Name</th> <th>Email</th> </tr> <?php $dbhost = "mariadb"; $dbuser = "ahmer"; $dbpass = "123"; $db = "testdb"; $dbconn = mysqli_connect($dbhost, $dbuser, $dbpass, $db); if(! $dbconn ) { die('Could not connect: ' . mysql_error()); } $query = mysqli_query($dbconn, "SELECT * FROM test") or die (mysqli_error($dbconn)); while ($row = mysqli_fetch_array($query)) { echo "<tr> <td>{$row['name']}</td> <td>{$row['email']}</td> </tr>"; } mysqli_close($dbconn); ?> </body> </html>
Open URL http://docker-01.centlinux.com in a web browser.
You can see that, our web page is now displaying data from the test table.
Setting up the LAMP stack on Docker provides a flexible and efficient environment for web development, allowing you to run your applications in isolated containers for better performance and scalability.

Thank
[murat@centos8 docker-lampserver]$ sudo docker-compose up
ERROR: yaml.parser.ParserError: while parsing a block mapping
in "./docker-compose.yml", line 1, column 1
expected , but found ''
in "./docker-compose.yml", line 14, column 2
[murat@centos8 docker-lampserver]$
It looks like you have a typo error in docker-compose.yml file at line 14 column 2. Please rectify it and continue.
Super Thx !
Great Tutorial
