Install on CentOS via RPM

Currently we support RHEL7 & CentOS7.

Add Zammad, Elasticsearch & epel-release RPM repos and install RPM

sudo yum -y install epel-release wget
sudo wget -O /etc/yum.repos.d/zammad.repo

echo "[elasticsearch-5.x]
name=Elasticsearch repository for 5.x packages
type=rpm-md" | sudo tee /etc/yum.repos.d/elasticsearch.repo

sudo yum -y install java elasticsearch
sudo systemctl daemon-reload
sudo systemctl enable elasticsearch
sudo systemctl start elasticsearch

sudo yum -y install zammad

SeLinux & Firewalld

On Centos SeLinux & Firewalld are possibly enabled. To get everything work you have to use the following commands:

setsebool httpd_can_network_connect on -P
firewall-cmd --zone=public --add-service=http --permanent
firewall-cmd --zone=public --add-service=https --permanent
firewall-cmd --reload

Go to http://localhost and you’ll see:

  • “Welcome to Zammad!”, there you need to create your admin user and invite other agents.

Change your webserver configuration (non localhost connections):

Add your fully qualified domain name or public IP to server name directive in your web server configuration and restart your web server. The installer will give you a hint where Zammad’s web server config file is located.



server {
    listen 80;

    # replace 'localhost' with your fqdn if you want to use zammad from remote
    server_name localhost;

You can manage the Zammad services manually:


sudo systemctl status zammad
sudo systemctl stop zammad
sudo systemctl start zammad
sudo systemctl restart zammad

Only web application server

sudo systemctl status zammad-web
sudo systemctl stop zammad-web
sudo systemctl start zammad-web
sudo systemctl restart zammad-web

Only worker process

sudo systemctl status zammad-worker
sudo systemctl stop zammad-worker
sudo systemctl zammad-worker
sudo systemctl restart zammad-worker

Only websocket server

sudo systemctl status zammad-websocket
sudo systemctl stop zammad-websocket
sudo systemctl start zammad-websocket
sudo systemctl restart zammad-websocket
