Table of Contents

Flarum is a lightweight, open-source forum software designed for simplicity, speed, and performance. Itโ€™s highly customizable, making it an excellent choice for self-hosting, where you can maintain full control over your data and tailor the platform to your communityโ€™s needs. In this guide, weโ€™ll cover installing Flarum, configuring Nginx, managing logs, setting up backups, updating Flarum, and utilizing its unique features.

Installing Flarum

๐Ÿ“ฆ Docker/Docker Compose Setup

To deploy Flarum using Docker, create and configure a docker-compose.yml file that orchestrates Flarum along with its dependencies.


version: '3.7'

services:

app:

image: flarum/flarum:latest

container_name: flarum_app

ports:

- "8000:80"

volumes:

- flarum_data:/flarum/app

environment:

- FLARUM_DATABASE_HOST=db

- FLARUM_DATABASE_NAME=flarum

- FLARUM_DATABASE_USER=flarum_user

- FLARUM_DATABASE_PASSWORD=securepassword

db:

image: mariadb:10.8

container_name: flarum_db

volumes:

- db_data:/var/lib/mysql

environment:

- MYSQL_ROOT_PASSWORD=rootpassword

- MYSQL_DATABASE=flarum

- MYSQL_USER=flarum_user

- MYSQL_PASSWORD=securepassword

volumes:

flarum_data:

db_data:

Deploy Flarum using Docker Compose:


docker-compose up -d

This will spin up both the Flarum app and its database. Access your Flarum instance at http://<your_server_ip>:8000.

๐Ÿš€ Manual Installation

To manually install Flarum on a Linux server, follow these steps:

  1. Install Dependencies: Ensure PHP, Composer, and a database (e.g., MySQL) are installed.

sudo apt update && sudo apt install -y php-cli php-mbstring php-xml unzip curl \

nginx mariadb-server composer

  1. Create a Database:

sudo mysql -u root -p

CREATE DATABASE flarum;

CREATE USER 'flarum_user'@'localhost' IDENTIFIED BY 'securepassword';

GRANT ALL PRIVILEGES ON flarum.* TO 'flarum_user'@'localhost';

FLUSH PRIVILEGES;

EXIT;

  1. Download and Install Flarum:

mkdir -p /var/www/flarum && cd /var/www/flarum

composer create-project flarum/flarum .

chown -R www-data:www-data /var/www/flarum

  1. Configure Permissions:

chmod -R 775 storage

chmod -R 775 public/assets

Flarum should now be accessible at your domain after configuring Nginx (covered next).

Configuring Nginx as a Reverse Proxy

๐ŸŒ Nginx Configuration

Create an Nginx server block to route traffic to your Flarum application.


server {

listen 80;

server_name yourdomain.com;

root /var/www/flarum/public;

index index.php;

location / {

try_files $uri $uri/ /index.php?$query_string;

}

location ~ \.php$ {

include snippets/fastcgi-php.conf;

fastcgi_pass unix:/var/run/php/php7.4-fpm.sock;

fastcgi_param SCRIPT_FILENAME $document_root$fastcgi_script_name;

include fastcgi_params;

}

location ~* \.(js|css|png|jpg|jpeg|gif|ico|svg|woff|woff2|ttf|eot|otf)$ {

expires max;

log_not_found off;

}

}

Test and reload the configuration:


sudo nginx -t

sudo systemctl reload nginx

๐Ÿ”’ SSL/TLS Setup

Secure Flarum with Let's Encrypt:


sudo apt install -y certbot python3-certbot-nginx

sudo certbot --nginx -d yourdomain.com

Automate certificate renewals:


sudo systemctl enable certbot.timer

Logging and Debugging Flarum

๐Ÿ—ƒ๏ธ Enabling Debug Logs

Enable debug mode in Flarum by editing the config.php file:


return [

'debug' => true,

// Other configurations...

];

๐Ÿ“„ Viewing Logs

To view logs, access the following locations:

  • Docker: docker logs flarum_app

  • Manual Installation: /var/www/flarum/storage/logs/flarum.log

๐Ÿ› ๏ธ Troubleshooting Common Issues

If you encounter errors, check:

  1. Permissions for the storage and public/assets directories.

  2. Database connection settings in config.php.

๐Ÿ“ค Exporting Logs

Set up log shipping to an external system (e.g., ELK Stack) with Filebeat:


sudo apt install -y filebeat

sudo filebeat modules enable nginx

sudo filebeat setup

sudo systemctl start filebeat

Backup and Restore

๐Ÿ—‚๏ธ File-Based Backups

Backup Flarumโ€™s files:


tar -czvf flarum_backup_$(date +%F).tar.gz /var/www/flarum

๐Ÿ”„ Database Backups

Export the database:


mysqldump -u flarum_user -p flarum > flarum_db_backup_$(date +%F).sql

Restore the database:


mysql -u flarum_user -p flarum < flarum_db_backup.sql

๐Ÿ“… Automated Backup Scripts

Automate backups with a cron job:


echo "0 2 * * * tar -czvf /backups/flarum_$(date +\%F).tar.gz /var/www/flarum && \

mysqldump -u flarum_user -p'password' flarum > /backups/flarum_db_$(date +\%F).sql" | crontab -

Updating and Upgrading Flarum

โฌ†๏ธ Updating Docker Images

Update Flarum if using Docker:


docker-compose pull app

docker-compose up -d

๐Ÿ› ๏ธ Manual Updates

For manual installations, update via Composer:


composer update

php flarum migrate

php flarum cache:clear

๐Ÿ” Checking for Updates

Check for available updates on the Flarum GitHub repository.

Leveraging Flarumโ€™s Unique Features

๐Ÿ”ง Enabling APIs

Activate Flarumโ€™s API by setting appropriate permissions for extensions:


php flarum permission:grant api access

Use the API with tools like curl:


curl -X GET "http://yourdomain.com/api/discussions" \

-H "Authorization: Token your_api_token"

๐ŸŒŸ Advanced Configurations

Extend Flarum with extensions:


composer require flarum/extension-slug

php flarum cache:clear
