How to Easily Deploy NodeBB Community Forum on Ubuntu VPS This installation guide is optimized for Ubuntu 24.04 LTS and will install NodeBB with MongoDB as the database. Fully patched LTS and equivalent production versions of software are assumed and used throughout. System Requirements Memory: Installing NodeBB's dependencies may require more than 512 MB of system memory. It is recommended to enable a swap partition to compensate if your Linux system has insufficient memory. Installing Node.js Naturally, NodeBB is driven by Node.js, and so it needs to be installed. Node.js is a rapidly evolving platform and so installation of the current LTS version of Node.js is recommended to make future updates seamless. The Node.js LTS Plan details the LTS release schedule including projected end-of-life. Node.js is available from the NodeSource Ubuntu binary distributions repository. Download and import the Nodesource GPG key sudo apt update sudo apt install -y ca-certificates curl gnupg sudo mkdir -p /etc/apt/keyrings curl -fsSL https://deb.nodesource.com/gpgkey/nodesource-repo.gpg.key | sudo gpg --dearmor -o /etc/apt/keyrings/nodesource.gpg Create deb repository echo "deb https://deb.nodesource.com/node_lts.x nodistro main" | sudo tee /etc/apt/sources.list.d/nodesource.list Run Update and Install sudo apt update sudo apt install nodejs npm -y Verify installation of Node.js and npm. You should have version lts of Node.js installed, and version 10 of npm installed: node -v npm -v (should output "10.2.3" or similar) Database Installing MongoDB Main Article: 🚀 How to Deploy MongoDB on Ubuntu VPS (5 Minute Quick-Start Guide) MongoDB is the default database for NodeBB. As noted in the MongoDB Support Policy versions older than 4.0 are officially End of Life as of October 2021. This guide assumes installation of 8.0. If you wish to use another database instead of MongoDB the Configuring Databases section has more information. Official detailed installation instructions can be found in the MongoDB manual. Although out of scope for this guide, some MongoDB production deployments leverage clustering, sharding and replication for high availability and performance reasons. Please refer to the MongoDB Replication and Sharding topics for further reading. Keep in mind that NodeBB does not require any of these advanced configurations, and doing so may complicate your installation. Keeping it simple often can be best. The following is an abbreviation of the official MongoDB installation guide for Ubuntu. If you're having issues, fall back to using that guide instead. sudo apt install gnupg curl -y curl -fsSL https://pgp.mongodb.com/server-8.0.asc | \ sudo gpg -o /usr/share/keyrings/mongodb-server-8.0.gpg \ --dearmor echo "deb https://repo.mongodb.org/apt/ubuntu noble/mongodb-org/8.0 multiverse" | sudo tee /etc/apt/sources.list.d/mongodb-org-8.0.list sudo apt update sudo apt install -y mongodb-org Verify installation of MongoDB. You should have version 8.0: mongod --version db version v8.0 Start the mongod service and verify service status: sudo systemctl start mongod sudo systemctl status mongod Configure MongoDB General MongoDB administration is done through the MongoDB Shell mongo. A default installation of MongoDB listens on port 27017 and is accessible locally. Access the shell: mongosh Switch to the built-in admin database: > use admin Create an administrative user (the is different from the nodebb user we'll create later). Replace the placeholder with your own selected password. Be sure that the are also not left behind. > db.createUser( { user: "admin", pwd: " ", roles: } ) This user is scoped to the admin database to manage MongoDB once authorization has been enabled. To initially create a database that doesn't exist simply use it. Add a new database called nodebb: > use nodebb The database will be created and context switched to nodebb. Next create the nodebb user with the appropriate privileges: > db.createUser( { user: "nodebb", pwd: " ", roles: } ) The readWrite permission allows NodeBB to store and retrieve data from the nodebb database. The clusterMonitor permission provides NodeBB read-only access to query database server statistics which are then exposed in the NodeBB Administrative Control Panel (ACP). Exit the Mongo Shell: > quit() Enable database authorization in the MongoDB configuration file /etc/mongod.conf by appending the following lines: security: authorization: enabled Restart MongoDB and verify the administrative user created earlier can connect: sudo systemctl restart mongod To connect to a MongoDB deployment that requires authentication, use the --username and --authenticationDatabase options. mongosh prompts you for a password, which it hides as you type. mongosh "mongodb://hostname:port" --username admin --authenticationDatabase admin If everything is configured correctly the Mongo Shell will connect. Exit the shell. Installing NodeBB First, we must install git as it is used to distribute NodeBB: sudo apt install -y git Note: commands like git and ./nodebb should not be used with root access (sudo or elevated privileges). It will cause problems with different ownership of files NodeBB needs access to. Next, clone NodeBB into an appropriate location. Here the local nodebb directory is used, though any destination is fine: git clone -b v3.x https://github.com/NodeBB/NodeBB.git nodebb cd nodebb This clones the NodeBB repository from the v3.x branch to the nodebb directory. A list of alternative branches are available in the NodeBB Branches GitHub page, but only the versioned branches are stable. NodeBB ships with a command line utility which allows for several functions. We'll first use it to setup NodeBB. This will install modules from npm and then enter the setup utility. ./nodebb setup A series of questions will be prompted with defaults in parentheses. The default settings are for a local server listening on the default port 4567 with a MongoDB instance listening on port 27017. When prompted for the mongodb username and password, enter nodebb, and the password that you configured earlier. Once connectivity to the database is confirmed the setup will prompt that initial user setup is running. Since this is a fresh NodeBB install a forum administrator must be configured. Enter the desired administrator information. This will culminate in a NodeBB Setup Completed message. Note: When entering your site URL, make sure it is exactly what you plan on accessing your site at. If you plan on visiting http://forum.example.com to open your forum, then enter exactly http://forum.example.com. A configuration file config.json will be created in the root of the nodebb directory. This file can be modified should you need to make changes such as changing the database location or credentials used to access the database. Finally, you can use the cli utility to start NodeBB: ./nodebb start Installing nginx NodeBB by default runs on port 4567, meaning that by default you must access it using a port number in addition to the hostname (e.g. http://example.org:4567) In order to allow NodeBB to be served without a port, nginx can be set up to proxy all requests to a particular hostname (or subdomain) to an upstream NodeBB server running on any port. sudo apt install -y nginx Verify the installation of nginx: nginx -v Verify that the service will run: sudo systemctl start nginx sudo systemctl status nginx You should now be able to go to your site's address in your browser and see the default Welcome to nginx! message. Configuring nginx NGINX-served sites are contained in a server block which are normally stored in separate files from the main nginx config (which is very rarely edited). When installing with the ppa above, the best way to install new nginx configs is to add new files in /etc/nginx/sites-available (like /etc/nginx/sites-available/forum.example.org). You then must link these files from sites-available to sites-enabled. The following demonstrates a typical series of commands when creating a new nginx config: cd /etc/nginx/sites-available sudo nano forum.example.com # config entered into file and saved cd ../sites-enabled sudo ln -s ../sites-available/forum.example.com Below is an example configuration for NodeBB running on port 4567. server { listen 80; server_name forum.example.com; location / { proxy_set_header X-Real-IP $remote_addr; proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for; proxy_set_header X-Forwarded-Proto $scheme; proxy_set_header Host $http_host; proxy_set_header X-NginX-Proxy true; proxy_pass http://127.0.0.1:4567; proxy_redirect off; # Socket.IO Support proxy_http_version 1.1; proxy_set_header Upgrade $http_upgrade; proxy_set_header Connection "upgrade"; } } After making changes to nginx configs, you have to reload the service for changes to take effect: sudo systemctl reload nginx For more information, go to the configuring nginx page. Set up HTTPS using Let’s Encrypt for secure connections: apt install certbot python3-certbot-nginx -y certbot --nginx -d forum.example.com After Installation Great, you have NodeBB installed and running. Login and access the NodeBB administrative portal from: https://forum.example.com/admin using the credentials created during the NodeBB setup. Conclusion You now know how to easily install NodeBB community forum on Ubuntu VPS. Cheers to your new self-hosted community discussion board, powered by NodeBB and Ubuntu VPS!
