Instructions for Installing InfluxDB 2 on Ubuntu 24.04 Using HTTPS
In this article, we will walk you through a step-by-step guide to set up InfluxDB 2 on Ubuntu 24.04 with HTTPS encryption using a reverse proxy like NGINX.
### Step 1: Install InfluxDB 2
1. **Download and Install InfluxDB 2**: First, download the latest version of InfluxDB 2 using the official install script.
```bash wget https://dl.influxdata.com/influxdb/releases/influxdb2-
2. **Start and Enable InfluxDB Service**: After installation, start and enable the InfluxDB service.
```bash sudo systemctl start influxdb sudo systemctl enable influxdb ```
### Step 2: Configure InfluxDB
1. **Initialize InfluxDB**: Initialize InfluxDB using the terminal to create the default buckets and provide an initial admin user.
```bash influx setup ```
2. **Configure InfluxDB Settings**: Adjust any necessary settings in the `/etc/influxdb/influxdb.conf` file. However, for HTTPS through a reverse proxy, you won't need to configure InfluxDB for HTTPS directly.
### Step 3: Generate SSL Certificates
1. **Generate Self-Signed Certificate or Use Existing Certificates**: You can use tools like OpenSSL to generate a self-signed certificate or use existing ones.
```bash openssl req -x509 -newkey rsa:2048 -nodes -out server.crt -keyout server.key -days 3650 -subj "/C=US/ST=State/L=Locality/O=Organization/CN=yourdomain.com" ```
Replace `yourdomain.com` with the appropriate domain name.
### Step 4: Configure NGINX as a Reverse Proxy
1. **Install NGINX**: If NGINX is not installed, you can install it using the following command:
```bash sudo apt update sudo apt install nginx ```
2. **Configure NGINX**: Create or edit an NGINX configuration file to serve as a reverse proxy for InfluxDB. Open the file in the `/etc/nginx/sites-available/` directory (e.g., `influxdb-proxy.conf`) and add the following configuration:
```nginx server { listen 443 ssl; server_name yourdomain.com;
ssl_certificate /path/to/server.crt; ssl_certificate_key /path/to/server.key;
location / { proxy_pass http://localhost:8086; proxy_set_header Host $host; proxy_set_header X-Real-IP $remote_addr; }
# Optional: Enable HTTP/2 http2_push_preload on; }
server { listen 80; server_name yourdomain.com; return 301 https://$server_name$request_uri; } ```
Replace `/path/to/server.crt` and `/path/to/server.key` with the actual paths to your SSL certificates. `yourdomain.com` should be replaced with your domain name.
3. **Enable NGINX Configuration**: Create a symbolic link to the configuration file from the `/etc/nginx/sites-enabled/` directory and reload NGINX:
```bash sudo ln -s /etc/nginx/sites-available/influxdb-proxy.conf /etc/nginx/sites-enabled/ sudo nginx -t sudo systemctl restart nginx ```
### Step 5: Access InfluxDB Through HTTPS
- After configuring NGINX, you can access InfluxDB via HTTPS by visiting `https://yourdomain.com`.
### Troubleshooting
- Ensure that the firewall allows incoming traffic on port 443 (HTTPS). - Check the NGINX logs for any errors (`/var/log/nginx/error.log`).
This setup will allow InfluxDB to be accessed securely through a reverse proxy using HTTPS. Enabling HTTPS (TLS) is essential for production, particularly when exposing the API or UI to external clients.
In the realm of technology, securing your home-and-garden IoT devices or improving your home-and-garden automation would be an exciting venture, especially by setting up InfluxDB 2 with HTTPS encryption for data collection and analysis. On the other hand, using InfluxDB 2 alongside data-and-cloud computing techniques in your lifestyle can help optimize your workflows and analyze patterns in a more efficient manner. The step-by-step guide provided above can be a starting point for both these scenarios, by securing InfluxDB 2 and configuring a reverse proxy like NGINX for encrypted communication.
