3.1. Setting up your LAMP web server for BrewPi¶
LAMP stands for Linux, Apache, MySQL, PHP: the applications that make up your web server. This article explains how to install all of them on your pi.
To install Apache2, execute the following commands:
sudo apt-get update sudo apt-get install apache2 sudo apt-get install libapache2-mod-php5 php5-cli php5-common php5-cgi
To test your server, you can now visit http://your-rpi-ip/.
By default, the root of your web server is
To install PHP, execute the following commands:
sudo apt-get install php5
Once you have installed PHP, you can test it by creating a new php file in your
Open the text editor nano to create the file:
sudo nano /var/www/phpinfo.php
This is what you want to put inside your file:
<?php phpinfo(); ?>
To exit nano and save your file, you can use
ctr-x, to write the file but keep nano open, you can use
For security reasons, your web server runs as a separate user under Linux, the
Your files in your /var/www/ directory should be owned by this user, otherwise your web server will not have the permissions to access the files. You can change owner of everything in your
/var/www/ directory to the
www-data group and user with the following command. The
-R flag recursively chowns all files and subdirectories.
sudo chown -R www-data:www-data /var/www
You can test your PHP installation by viewing the result of your new file in a browser: http://your-rpi-ip/phpinfo.php. If that worked, please delete the file:
sudo rm /var/www/phpinfo.php
If you ever need to restart your web server, you can use this command:
sudo /etc/init.d/apache2 restart
The current version of BrewPi doesn’t use MySQL. It is recommended to not install it. If you want MySQL anyway, you can install it with these commands:
sudo apt-get install mysql-server mysql-client php5-mysql
To manage your databases from a web interface, you can install PHPMyAdmin:
sudo apt-get install libapache2-mod-auth-mysql php5-mysql phpmyadmin
Remember to select Apache2 with the space bar when it comes up! After installation, reboot and test: http://your-rpi-ip/phpmyadmin. Reboot with the command:
sudo shutdown -r now
To easily see when your pi is back online, create a shortcut in your quick launch bar with the following target (for the correct IP address of course):
C:\Windows\System32\cmd.exe /c "ping -t 192.168.0.6"
That will open a command window that keeps pinging your Raspberry Pi.
If you mess up the installation of MySQL, because you didn’t listen and did not expand your root partition, it can be a bitch to remove and re-install. The following worked for me eventually:
sudo apt-get autoremove --purge mysql-server mysql-server-5.5 mysql-common sudo rm /var/lib/mysql/ -rf sudo rm /etc/mysql -rf sudo apt-get install -f mysql-server
