System Requirements

Step 1: Download Zentyal ISO

1. Visit the official site: https://zentyal.com.
2. Navigate to Get Zentyal gt Downloads.
3. Choose the latest stable LTS release (e.g., Zentyal 7.0 LTS).
4. Download the ISO image.
5. Pro tip: Grab a coffee while it downloads—time well spent.

Step 2: Prepare Installation Media

Use one of these methods to create a bootable USB stick:

• Windows: Use Rufus.
• Linux: Run dd if=zentyal.iso of=/dev/sdX bs=4M status=progress (replace sdX with your USB device).

CAUTION: Ensure you select the correct /dev/sdX or you might accidentally erase your cats videos.

Step 3: Boot amp Begin Installation

1. Insert the USB stick and reboot your machine.
2. Enter BIOS/UEFI and select USB as the first boot device.
3. At the GRUB menu, choose Install Zentyal.
4. Select your language, keyboard layout, and locale.

Disk Partitioning

Choose one of:

• Guided – use entire disk: Quick and easy, wipes everything.
• Manual: For custom partitions (/, /home, swap, etc.).

Step 4: Configure Networking

1. Assign a static IP address for the server:
• IP: e.g., 192.168.1.10
• Netmask: 255.255.255.0
• Gateway: 192.168.1.1
• DNS: 8.8.8.8 (or your preferred resolver)
2. Confirm and continue.

Step 5: Set Time Zone amp Root Password

Select your time zone on the map, then choose a strong root password. Remember: P@ssw0rd is not strong. Aim for something like BlueElePhant!42.

Step 6: Zentyal Modules Selection

Once the base system installs and reboots, the first-boot wizard will appear. Here you select which modules you need. Popular choices:

• Domain amp Directory (OpenLDAP Samba)
• File Sharing (Samba)
• Mail (Postfix Dovecot)
• Gateway (Firewall, NAT, VPN)
• DNS amp DHCP

Tip: Don’t overload one box with every module—spread the load if you can.

Step 7: Module Configuration

Navigate to each selected module in the web admin interface (https://your-server-ip:8443), then:

Domain amp Directory

1. Create your first organization unit (OU).
2. Add your users and groups.
3. Configure policies (password complexity, login restrictions).

File Sharing

1. Define shared folders.
2. Set ACLs for users/groups.
3. Enable Windows file sharing (SMB).

DNS amp DHCP

1. Configure forward/reverse zones.
2. Define DHCP pools and leases.
3. Set DNS options (search domains, TTL).

Mail

1. Define mail domains.
2. Create mailboxes for users.
3. Set spam filtering (SpamAssassin).

Step 8: Firewall amp Security

• Go to the Gateway module.
• Set up external (WAN) and internal (LAN) interfaces.
• Create firewall rules: allow HTTP/HTTPS, SMB, SMTP as needed.
• Enable intrusion detection (optional but recommended).

Step 9: Backup amp Maintenance

Even the mightiest server can trip over its own cables—backups save the day:

• Use the Backup module to schedule daily snapshots.
• Store backups off-site or on a separate disk.
• Test restores periodically. Because a backup that never restores is just an expensive disk space.

Troubleshooting Tips

• Cannot reach web UI? Check your firewall rules and ensure port 8443 is open.
• DNS resolution fails? Verify your forward/reverse zones and /etc/resolv.conf.
• Mail stuck in queue? Inspect /var/log/mail.log for errors.
• Users can’t log in? Confirm LDAP connectivity with ldapsearch tools.
