Install on CentOS via RPM

Note

Currently we support RHEL7 & CentOS7.

Prerequisites

Setup Elasticsearch

Elasticsearch is a dependency of Zammad and needs to be provided before installing Zammad. Please take a look at the following page: Set up Elasticsearch .

Add Zammad-Repo and Install Zammad

sudo yum -y install epel-release wget
sudo wget -O /etc/yum.repos.d/zammad.repo https://dl.packager.io/srv/zammad/zammad/stable/installer/el/7.repo

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.

nginx

Warning

Please do not rename the webserver config file for nginx or apache. The update process will re create it, if it does not exist!

/etc/nginx/conf.d/zammad.conf

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:

Zammad

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
