Let’s Get Started!

Setting up a LAMP (Linux, Apache, MySQL, PHP) stack using Podman is similar to using Docker, but with some differences due to the way Podman handles containers and networking. Podman is daemonless and designed to be compatible with Docker, but it operates under a different security model and doesn’t require a running daemon.

Here’s a step-by-step guide to set up a LAMP stack using Podman:

  • SSH to the Rocky8 box
    • # ssh [username]@[ip address of box]
  • We are using Rocky8 for this Lab
    • # cat /etc/os-release
  • Verify Podman is installed if not install it
    • # podman –version
  • Looks like Podman is installed, if not follow the instructions here.
  • Create a directory for the project
    • # pwd – where are we in the file system
    • # ll – list the directory
    • # mkdir Projects && mkdir /Projects/lamp-podman && cd /Projects/lamp-podman
    • # pwd
  • Create a non-root user with root privileges, enable linger for the user
    • # useradd -c “Podman User” -G wheel poduser
    • # loginctl enable-linger poduser
  • Switch user to poduser, add the epel-release repo in order to install podman-compose then create the following file inside of the directory, ‘podman-compose.yml’.
    • # dnf config-manager –set-enabled powertools
    • # dnf install epel-release
    • # su – poduser
    • # sudo dnf install podman-compose -y
    • # podman-compose –version
    • # touch podman-compose.yml
  • Inside of the ‘podman-compose.yml’ file should look like this
    • # vim podman-compose.yml
    • Apache & PHP
      • Use an image that includes both Apache and PHP.
      • Map the default Apache port to a port on your host machine.
      • Mount a directory from your host to the container for the website file.
    • MySQL
      • Use the official MySQL image.
      • Define environment variables for the MySQL root password, database, user, and user password.
      • Optionally, mount a volume for persistent storage of MySQL data.
    • PHPMyAdmin
      • Use the official PHPMyAdmin image.
      • Link it to the MySQL container.
      • Map a port for PHPMyAdmin.
  • Create a ‘www’ directory in the project folder for the website files
    • # mkdir www
    • # ll
  • Start the containers. Run the following command in the same directory as your ‘podman-compose.yml’.
    • # podman-compose up -d
  • Accessing the servers.
    • Apache [ip address]:8000
    • PHPMyAdmin [ip address]:8080
  • Testing PHP
    • Create a ‘phpinfo.php’ file in the ‘www’ directory:
      • $ touch phpinfo.php
      • $ vim <?php phpinfo(); ?>
    • Visit [ip address]:8000/phpinfo.php
  • Check the containers running then shutdown the containers.
    • $ podman ps
    • $ podman-compose down
