How to Install Uptime Kuma on Ubuntu 22.04

Spread the love

Uptime Kuma is an open-source monitoring solution. We can monitor our websites and servers’ uptime and configure them to send us notifications via multiple options, like Telegram, email, Discord, etc. Uptime Kuma is an easy-to-use monitoring tool, and it is powerful for traffic control, observability, service discovery, etc. This article will show you how to install Uptime Kuma on Ubuntu 22.04.

Prerequisites

  • An Ubuntu server 22.04
  • SSH access with root privileges

Step 1. Log in to the server

First, log in to your Ubuntu 22.04 VPS through SSH as the root user:

ssh root@IP_Address -p Port_number

You would need to replace ‘IP_Address‘ and ‘Port_number‘ with your server’s IP address and SSH port number.

Before starting, we need to make sure that all Ubuntu 22.04 packages installed on the server are up to date. You can do this by executing the following commands:

# apt update -y

Step 2. Create a System User

In this step, we will create a new system user and grant it sudo privileges. Let’s say the new system user is called ‘master’; you can choose any username you like.

# adduser master

Next, let’s run the command below to add the new user to sudo group. In Ubuntu operating system, users who are members of sudo group are allowed to run sudo commands.

# usermod -aG sudo master

Once created and given sudo privileges, we can log in as the new user ‘master’, and we will use this user to run commands and complete the Uptime Kuma installation.

# su - master

Step 3. Install NodeJS and NPM

Uptime Kuma requires NodeJS runtime environment and npm. We can install NodeJS from the Ubuntu default repository, but we will get an older version of NodeJS if we use this method and Uptime Kuma requires at least NodeJS version 14. In this step, we will install NodeJS and npm through the NodeJS repository to get the most recent version of it.

$ curl -sL https://deb.nodesource.com/setup_lts.x | sudo -E bash -

Once completed, we need to download the package information from the newly added source above.

$ sudo apt update

Next, run the following command to install NodeJS and NPM finally.

$ sudo apt install nodejs

That’s it; nodejs and NPM are installed; you can check the installed version by executing this one-liner:

$ node -v; npm -v

You will see an output like this:

master@ubuntu22:~$ node -v; npm -v
v16.18.0
8.19.2

Step 4. Install Uptime Kuma

Uptime Kuma is not available in the default Ubuntu repository. We can install it by downloading it from GitHub using git.

$ sudo apt install git

After git is installed, we can continue to clone Uptime Kuma from its GitHub repository.

$ git clone https://github.com/louislam/uptime-kuma.git
$ cd uptime-kuma

It’s time to run the installation using the NPM package manager of Nodejs.

$ npm run setup

Step 5. Install PM2

With Process Manager (PM2), we can keep our applications alive forever, reload them without downtime, and facilitate common system admin tasks. Execute the command below to install PM2 on your Ubuntu 22.04.

$ sudo npm install pm2 -g

Once pm2 is installed, we can run our Uptime Kuma with this command.

$ pm2 start server/server.js --name kuma

Now, you can open your web browser and navigate to the page at http://YOUR_SERVER_IP_ADDRESS:3001, and you will see the uptime Kuma welcome page, you can create a new user now.

To add monitoring, you can click on the ‘Add New Monitor’ button

You can customize and configure your monitoring here.

After starting Uptime Kuma, we can create a service file for PM2 to make Uptime Kuma start automatically upon reboot.

$ pm2 startup

You will get an output like this:

[PM2] Init System found: systemd
[PM2] To setup the Startup Script, copy/paste the following command:
sudo env PATH=$PATH:/usr/bin /usr/lib/node_modules/pm2/bin/pm2 startup systemd -u master --hp /home/master

Just follow the instruction shown on the screen, for example:

$ sudo env PATH=$PATH:/usr/bin /usr/lib/node_modules/pm2/bin/pm2 startup systemd -u master --hp /home/master

Then, you will also see an output like this one:

Now we need to save the current ongoing process:

$ pm2 save

Step 6. Install and Configure NGINX

Your Uptime Kuma install has now been completed, and you should be able to access it at your server’s public IP with port number 3001. However, if you want to access your Uptime Kuma website using a domain name or subdomain name instead of typing the server’s IP address and the port number in the URL, you would need to configure a reverse proxy on your server.

This step will show you how to implement the reverse proxy configuration using Nginx.

First, install Nginx with the following command:

$ sudo apt install nginx

On Ubuntu 22.04, Nginx is configured to start running upon installation; you can check it by running this command:

$ sudo systemctl status nginx

Once installed, create a new Nginx server block configuration file. Replace kuma.yourdomain.com with your actual domain or subdomain name:

$ sudo nano /etc/nginx/sites-enabled/kuma.yourdomain.com.conf

Add the following content to the file:

server {

listen 80;
server_name kuma.yourdomain.com;
location / {
    proxy_pass http://localhost:3001;
    proxy_http_version 1.1;
    proxy_set_header Upgrade $http_upgrade;
    proxy_set_header Connection "upgrade";
    proxy_set_header Host $host;
    }

location ~ /.well-known {
    alias /var/www/html;
    }
}

Save the file by pressing CTRL + O, then press CTRL + X to exit the nano editor, then restart Nginx.

$ sudo systemctl restart nginx

Step 7. Install SSL certificate

This is an optional step but highly recommended to complete. We will install a free SSL certificate from Let’s Encrypt.

$ sudo apt install python3-certbot-nginx -y

Once completed, we can run this command to install the SSL certificate.

$ sudo certbot certonly -d kuma.yourdomain.com

master@ubuntu22:~#

Make sure to pay attention to these lines; we need them when editing our nginx server block.

Certificate is saved at: /etc/letsencrypt/live/kuma.yourdomain.com/fullchain.pem
Key is saved at: /etc/letsencrypt/live/kuma.yourdomain.com/privkey.pem

Next, we need to edit the nginx server block for kuma.yourdomain.com

$ sudo nano /etc/nginx/sites-enabled/kuma.yourdomain.com.conf

Replace the content with the lines below.

server {
    listen 443 ssl http2;
    server_name kuma.yourdomain.com;
    ssl_certificate /etc/letsencrypt/live/kuma.yourdomain.com/fullchain.pem;
    ssl_certificate_key /etc/letsencrypt/live/kuma.yourdomain.com/privkey.pem;

location / {
    proxy_set_header X-Real-IP $remote_addr;
    proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for;
    proxy_set_header Host $host;
    proxy_pass http://localhost:3001/;
    proxy_http_version 1.1;
    proxy_set_header Upgrade $http_upgrade;
    proxy_set_header Connection "upgrade";
    }
}

server {
    listen 80;
    server_name kuma.yourdomain.com;
    return 301 https://kuma.yourdomain.com$request_uri;
}

Save the file, then exit and restart nginx

$ sudo systemctl restart nginx

Now, you should be able to access your Uptime Kuma website in HTTPS mode at https://kuma.yourdomain.com; you can proceed with building your application using the Uptime Kuma.
