Install and Configure Uptime Kuma on AlmaLinux
Prerequisites
- An AlmaLinux 9 dedicated server or KVM VPS.
- A user with sudo privileges.
- Basic knowledge of terminal commands.
Step 1: Update Your System
Before installing any software, it’s a good practice to update your system’s package index and upgrade all installed packages to their latest versions.
sudo dnf update -y
Step 2: Install Node.js and npm
Uptime Kuma is built with Node.js, so you need to have Node.js and npm (Node Package Manager) installed on your server.
Install Node.js from the NodeSource repository:
curl -fsSL https://deb.nodesource.com/setup_18.x | sudo -E bash -
sudo dnf install -y nodejs
Verify the installation:
node -v
npm -v
Step 3: Clone and Install Uptime Kuma
Install Git if not installed already. Git is required to clone the Uptime Kuma repository.
sudo dnf install -y git
Clone the Uptime Kuma repository from GitHub to your server.
git clone https://github.com/louislam/uptime-kuma.git
cd uptime-kuma
Let's proceed with the installation process.
Install the required dependencies and build Uptime Kuma.
npm run setup
Step 4: Install and Run PM2
To run Uptime Kuma in the background, you can use a process manager like pm2.
Install pm2 globally:
sudo npm install pm2 -g && pm2 install pm2-logrotate
Start Uptime Kuma with pm2:
pm2 start server/server.js --name uptime-kuma
To ensure Uptime Kuma starts on boot, use the following command:
pm2 startup
pm2 save
Step 5: Configure Firewall
If you have enabled firewall, you need to add HTTP and HTTPS ports in the firewall.
firewall-cmd --add-port=80/tcp --permanent
firewall-cmd --add-port=443/tcp --permanent
firewall-cmd --reload
Configure SELinux (Optionally)
If you have enabled SELinux in your server, follow this step.
You can adjust the SELinux policies to allow Nginx to connect to the upstream server:
sudo setsebool -P httpd_can_network_connect 1
Step 6: Install Nginx and Certbot
Install Nginx:
sudo dnf install -y nginx
Install Certbot:
sudo dnf install -y certbot python3-certbot-nginx
Configure Nginx for Uptime Kuma:
sudo nano /etc/nginx/conf.d/uptime-kuma.conf
Add the following configuration:
server {
listen 80;
server_name your_domain;
location / {
proxy_pass http://localhost:3001;
proxy_set_header Host $host;
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;
}
}
Replace your_domain with your actual domain name.
Test and restart Nginx:
sudo nginx -t
sudo systemctl restart nginx
Replace your_domain with your domain name. Obtain an SSL certificate:
sudo certbot --nginx -d your_domain
Follow the prompts to obtain the certificate.
Step 7: Configure Uptime Kuma
Open your web browser and go to https://your_domain. You should see the Uptime Kuma login page.
Create an admin account by filling out the registration form.
Once logged in, you can start adding your monitors. Click on "Add New Monitor" and fill in the required details such as:
- Friendly Name: A name for the monitor.
- URL: The URL of the website you want to monitor.
- Type: Select the type of monitor (HTTP(s), TCP, Ping, etc.).
- Interval: Set how often you want to check the URL.
After filling in the details, click on "Save" to add the monitor.
Now you can access Uptime Kuma securely via https://your_domain.
