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:

$ 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-worker
$ sudo systemctl zammad-worker
$ sudo systemctl restart zammad-worker
