Ever tried setting up a Wazuh server and ended up with a headache? Your not alone! After spending countless hours figuring this out myself, I’ve decided to share my experience and create this comprehensive guide that actually works.
TL;DR
Setting up a Wazuh server might seem daunting, but with the right steps, you’ll have it running in about 30 minutes. We’ll cover everything from system requirements to troubleshooting common hiccups.
Prerequisites
Before we dive in, make sure you’ve got:
- A Linux server (I used Ubuntu 22.04 LTS, but other versions work to)
- Minimum 4GB RAM (8GB recommended for production)
- At least 50GB storage space
- Root or sudo access
- Basic command line knowledge
- Coffee ☕ (trust me, you’ll need it)
Step 1: Preparing Your System
First things first, lets update our system. Open your terminal and run:
sudo apt-get update
sudo apt-get upgrade -y
Pro tip: Sometimes the upgrade command might hang – if that happens, just hit Ctrl+C and run it again. Works like a charm!
Step 2: Installing Dependencies
Wazuh needs some friends to work properly. Let’s get them:
sudo apt-get install curl apt-transport-https unzip wget libcap2-bin software-properties-common lsb-release gnupg2
I once forgot to install gnupg2 and spent 2 hours debugging. Don’t be like me!
Step 3: Adding Wazuh Repository
Now comes the interesting part. We need to add Wazuh’s repository:
curl -s https://packages.wazuh.com/key/GPG-KEY-WAZUH | gpg --no-default-keyring --keyring gnupg-ring:/usr/share/keyrings/wazuh.gpg --import && chmod 644 /usr/share/keyrings/wazuh.gpg
echo "deb [signed-by=/usr/share/keyrings/wazuh.gpg] https://packages.wazuh.com/4.x/apt/ stable main" | sudo tee -a /etc/apt/sources.list.d/wazuh.list
Step 4: Installing Wazuh Manager
Here’s where the magic happens:
sudo apt-get update
sudo apt-get install wazuh-manager
The installation might take a few minutes. Perfect time to refill that coffee!
Step 5: Verifying Installation
Let’s make sure everything’s running smoothly:
sudo systemctl status wazuh-manager
If you see “active (running)” – congratulations! Your basic setup is complete.
Common Issues and Solutions
Problem 1: Port 1514 Already in Use
This happened to me twice! Check what’s using the port:
sudo netstat -tulpn | grep 1514
Problem 2: Service Won’t Start
Usually, this is because of insufficient memory. Try:
free -m
If you’re below 2GB available, time to close some Chrome tabs! 😅
Best Practices
- Always backup your configuration files
- Monitor your logs regularly
- Keep your system updated
- Don’t forget to configure your firewall
