Zammad Installation Prerequisites:

Zammad is an open source project which can be deployed on a VPS server of your choice.

You can get a 2GB RAM VPS from Linode for $10, but it’s unmanaged. If you want a Managed VPS, then use our new BlueHost Promotion Offer, you will get upto 40% OFF on hosting with one Free Domain for Life. If you get a Managed VPS, they will probably install Zammad for you.

In this article we will explain how to install and configure Zammad open source helpdesk/customer support ticketing system in CentOS/RHEL 7, Ubuntu 16.04 and Debian 9 server.

Step 1: Configure System Locale on System

1. Zammad uses UTF-8 locale, otherwise, packages such as PostgreSQL will not install. Check your system locale using following command on your respective Linux distribution.

# locale
LANG=en_IN
LC_CTYPE="en_IN"
LC_NUMERIC="en_IN"
LC_TIME="en_IN"
LC_COLLATE="en_IN"
LC_MONETARY="en_IN"
LC_MESSAGES="en_IN"
LC_PAPER="en_IN"
LC_NAME="en_IN"
LC_ADDRESS="en_IN"
LC_TELEPHONE="en_IN"
LC_MEASUREMENT="en_IN"
LC_IDENTIFICATION="en_IN"
LC_ALL=


If there is nothing with UTF-8 in the above output, you have to set a new locale using following command.

# localectl set-locale LANG=en_US.UTF-8
# locale status
System Locale: LANG=en_US.UTF-8
VC Keymap: us
X11 Layout: us

Step 2: Install Elasticsearch on System

2. Now install Elasticsearch using following commands according to your Linux distribution you are using.

Install Elasticsearch on CentOS/RHEL 7

# rpm --import https://artifacts.elastic.co/GPG-KEY-elasticsearch
# echo "[elasticsearch-5.x]
name=Elasticsearch repository for 5.x packages
baseurl=https://artifacts.elastic.co/packages/5.x/yum
gpgcheck=1
gpgkey=https://artifacts.elastic.co/GPG-KEY-elasticsearch
enabled=1
autorefresh=1
type=rpm-md" | sudo tee /etc/yum.repos.d/elasticsearch.repo
# yum -y install java elasticsearch
# /usr/share/elasticsearch/bin/elasticsearch-plugin install ingest-attachment
# systemctl daemon-reload
# systemctl enable elasticsearch
# systemctl start elasticsearch
# systemctl status elasticsearch

Install Elasticsearch on Ubuntu 16.04

# echo "deb https://artifacts.elastic.co/packages/5.x/apt stable main" | sudo tee -a /etc/apt/sources.list.d/elastic-5.x.list
# wget -qO - https://artifacts.elastic.co/GPG-KEY-elasticsearch | sudo apt-key add -
# apt-get update
# apt-get install openjdk-8-jre elasticsearch
# /usr/share/elasticsearch/bin/elasticsearch-plugin install ingest-attachment
# systemctl restart elasticsearch
# systemctl enable elasticsearch
# systemctl status elasticsearch

Install Elasticsearch on Debian 9

# apt-get install apt-transport-https sudo wget
# echo "deb http://ftp.debian.org/debian jessie-backports main" | sudo tee -a /etc/apt/sources.list.d/debian-backports.list
# echo "deb https://artifacts.elastic.co/packages/5.x/apt stable main" | sudo tee -a /etc/apt/sources.list.d/elastic-5.x.list
# wget -qO - https://artifacts.elastic.co/GPG-KEY-elasticsearch | sudo apt-key add -
# apt-get update
# apt-get install -t jessie-backports openjdk-8-jre
# apt-get install elasticsearch
# /var/lib/dpkg/info/ca-certificates-java.postinst configure
# /usr/share/elasticsearch/bin/elasticsearch-plugin install ingest-attachment
# systemctl restart elasticsearch
# systemctl enable elasticsearch
# systemctl status elasticsearch

Step 3: Install Zammad Support Ticket System

3. Once Elasticsearch has been installed, now you can add Zammad official repository to install Zammad, this will also install required packages such as Nginx HTTP server and PostgreSQL from this repository using following commands according to your distribution.

Install Zammad on CentOS/RHEL 7

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

Install Zammad on Ubuntu 16.04

# wget -qO- https://dl.packager.io/srv/zammad/zammad/key | sudo apt-key add -
# wget -O /etc/apt/sources.list.d/zammad.list https://dl.packager.io/srv/zammad/zammad/stable/installer/ubuntu/16.04.repo
# apt-get update
# apt-get install zammad

Install Zammad on Debian 9

# wget -qO- https://dl.packager.io/srv/zammad/zammad/key | sudo apt-key add -
# wget -O /etc/apt/sources.list.d/zammad.list https://dl.packager.io/srv/zammad/zammad/stable/installer/debian/9.repo
# apt-get update
# apt-get install zammad

4. Once Zammad has been installed, you can find all its packages under /opt/zammad (default base directory) and all the Zammad services (zammad, zammad-web, zammad-worker and zammad-websocket) are started automatically, you can view their status using following commands.

#systemctl status zammad
#systemctl status zammad-web
#systemctl status zammad-worker
#systemctl status zammad-websocket

5. You can also manage (restart, stop, start, disable, enable, etc..) any of these services like other systemd services using following commands.

--------- Zammad Server --------- # systemctl status zammad
# systemctl stop zammad
# systemctl start zammad
# systemctl restart zammad
--------- Zammad Web Application Server ---------
# systemctl status zammad-web
# systemctl stop zammad-web
# systemctl start zammad-web
# systemctl restart zammad-web
--------- Zammad Worker Process ---------
# systemctl status zammad-worker
# systemctl stop zammad-worker
# systemctl start zammad-worker
# systemctl restart zammad-worker
--------- Zammad Websocket Server ---------
# systemctl status zammad-websocket
# systemctl stop zammad-websocket
# systemctl start zammad-websocket
# systemctl restart zammad-websocket

Step 4: Verify Nginx and PostgreSQL Services

6. The Nginx web server is started automatically, a server block for Zammad is created and auto-configured in /etc/nginx/conf.d/zammad.conf, that you confirm using following commands.

# cat /etc/nginx/conf.d/zammad.conf
# systemctl status nginx

7. The PostgreSQL database server is also auto-started and configured to work with Zammad that you can verify using following command.

# systemctl status postgresql

Step 5: Configure Nginx Server Block for Zammad

8. Now it’s time to configure nginx server block for Zammad, open the configuration file.

# vi /etc/nginx/conf.d/zammad.conf

Add your fully qualified domain name or Public IP to server name directive as shown.

server {
listen 80;
# replace 'localhost' with your fqdn if you want to use zammad from remote
server_name domain.com;
Configure Nginx for Zammad

Configure Nginx for Zammad

Save the changes and exit the file. Then restart Nginx services for the recent changes to take effect.

# systemctl restart nginx

Important: On CentOS, SeLinux & Firewalld are possibly enabled. To get everything work you need to open the port 80 (HTTP) and 443 (HTTPS) to allow client requests to the Nginx web server, as follows:

# 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

Step 6: Install Zammad via Web Installer
