Zammad Requirements

• Elasticsearch for searching performance
• Database: PostgreSQL (supported by default), MariaDB or MySQL
• Reverse Proxy: Nginx (supported by default) or Apache.

    rpm --import https://artifacts.elastic.co/GPG-KEY-elasticsearch
    echo "[elasticsearch-7.x]
    name=Elasticsearch repository for 7.x packages
    baseurl=https://artifacts.elastic.co/packages/7.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-7.x.repo
    yum install -y elasticsearch
    /usr/share/elasticsearch/bin/elasticsearch-plugin install ingest-attachment
    systemctl start elasticsearch
    systemctl enable elasticsearch    

Step 2 Install Zammad on the system through yum

    # 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    

Step 3 Check the status of Zammad Server

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

Step 4 Verify the PostgreSQL and Nginx service both are running and are up

    # systemctl status nginx
    # systemctl status  postgresql    

Step 5 Configure Nginx for the Zammad. Edit the below file and enter your System public IP address.

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

Step 6 In the last, check for the firewall and SELinux.
