Install Graylog

  1. Install Elastic Search giving the cluster name of graylog
  2. Install Graylog:
    cat > /tmp/graylog.list << EOF
    deb stable 2.3
    sudo mv /tmp/graylog.list /etc/apt/sources.list.d/
    wget -q -O - | sudo apt-key add -
    sudo apt-get update
    sudo apt-get install -y pwgen authbind graylog-server
    sudo systemctl daemon-reload
    sudo systemctl enable graylog-server.service
    sudo sed -i "s/password_secret =/password_secret = $(pwgen -N 1 -s 96)/g" /etc/graylog/server/server.conf
    sudo sed -i "s/root_password_sha2 =/root_password_sha2 = $(echo -n password | shasum -a 256 | awk '{ print $1 }')/g" /etc/graylog/server/server.conf
    sudo sed -i "s/#elasticsearch_max_time_per_index = 1d/elasticsearch_max_time_per_index = 1w/g" /etc/graylog/server/server.conf
    sudo sed -i "s/elasticsearch_max_number_of_indices = 20/elasticsearch_max_number_of_indices = 8/g" /etc/graylog/server/server.conf
    sudo swapoff -a
    sudo systemctl start graylog-server.service
  3. Lastly, configure NGINX to be a reverse proxy for Graylog:
    cat >> /tmp/graylog << EOF
      listen      80 default_server;
      listen      [::]:80 default_server ipv6only=on;
      server_name $(hostname -f);
      location /
            proxy_set_header    Host \$http_host;
            proxy_set_header    X-Forwarded-Host \$host;
            proxy_set_header    X-Forwarded-Server \$host;
            proxy_set_header    X-Forwarded-For \$proxy_add_x_forwarded_for;
            proxy_set_header    X-Graylog-Server-URL http://$(hostname -f)/api;
    sudo mv /tmp/graylog /etc/nginx/sites-available/
    sudo rm /etc/nginx/sites-enabled/default
    sudo ln -s /etc/nginx/sites-available/graylog /etc/nginx/sites-enabled/graylog
    sudo service nginx reload
