Run the following commands to deploy Zulip with Docker Compose:
nano docker-compose.yml
## Deploy Zulip
docker-compose up -d
## Verify containers are running
docker ps
🚀 Manual Installation
If you prefer a manual setup, you can install Zulip directly on a Linux server (Ubuntu 20.04 is recommended). Use the following commands:
## Update and install dependencies
sudo apt update && sudo apt upgrade -y
sudo apt install -y git curl wget apt-transport-https gnupg
## Add Zulip repository (replace <version> with the desired Zulip version)
wget https://raw.githubusercontent.com/zulip/zulip/<version>/scripts/setup/install
chmod +x install
sudo ./install [email protected] --hostname=chat.example.com
## Follow the prompts to complete the installation
Configuring Nginx as a Reverse Proxy
🌐 Nginx Configuration
Configure Nginx to serve Zulip by creating a server block file for your domain:
sudo nano /etc/nginx/sites-available/zulip
Add the following configuration, replacing chat.example.com with your domain:
server {
listen 80;
server_name chat.example.com;
location / {
proxy_pass http://127.0.0.1:9991;
proxy_set_header Host $host;
proxy_set_header X-Real-IP $remote_addr;
proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for;
}
}
Enable the configuration and restart Nginx:
sudo ln -s /etc/nginx/sites-available/zulip /etc/nginx/sites-enabled/
sudo nginx -t
sudo systemctl reload nginx
🔒 SSL/TLS Setup
Secure your Zulip instance with Let's Encrypt:
## Install Certbot
sudo apt install certbot python3-certbot-nginx -y
## Generate SSL certificate
sudo certbot --nginx -d chat.example.com
## Verify SSL renewal
sudo certbot renew --dry-run
Logging and Debugging Zulip
🗃️ Enabling Debug Logs
To enable debug-level logging in Zulip, update the settings.py file:

Restore the database with:
## Docker-based setup
docker exec -i zulip-db psql -U zulip zulip < zulip-db-backup.sql
## Manual setup
sudo -u postgres psql zulip < zulip-db-backup.sql
📅 Automated Backup Scripts
Set up a cron job for periodic backups:
## Open crontab
crontab -e
## Add backup job (daily at 2 AM)
0 2 * * * tar -czvf /backups/zulip-backup-$(date +\%F).tar.gz /etc/zulip /var/uploads
