By rami.sedhom, 25 March, 2022

Download Kong OSS v1.5 for RHEL: curl -Lo kong-1.5.0.rhel7.amd64.rpm $( rpm --eval "https://download.konghq.com/gateway-1.x-rhel-7/Packages/k/kong-1.5.0.rhel7.amd64.rpm")
Install it: sudo yum install kong-1.5.0.rhel7.amd64.rpm
Init configuration to use YAML file instead of database, following command create kong.yml in home directory: kong config init
Create kong configuration file from the default file:
cd /etc/kong
sudo cp kong.conf.default kong.conf
Change configuration file so it is aware of the YAML declarative configuration file:
database = off
declarative_config = /home/apiteam/kong.yml
Run Kong migrations: kong migrations bootstrap
Add kong path to $PATH of sudoer secure_path⁽²⁾: by running sudo visudo and edit the secure path line:
Defaults secure_path = /sbin:/bin:/usr/sbin:/usr/bin:/usr/local/bin
Change admin_listen to allow connection from any client⁽³⁾:
-#admin_listen = 127.0.0.1:8001, 127.0.0.1:8444 ssl +admin_listen = 0.0.0.0:8001, 127.0.0.1:8444 ssl
Start Kong: sudo kong start
Verify the installation by checking the Admin API: curl -l http://localhost:8001`
It should return 200 status code

By default, Kong listens on the following ports:
- :8000: Port on which listens for incoming HTTP traffic from your clients, and forwards it to your upstream services.
- :8443: Port on which listens for incoming HTTPS traffic. This port has similar behavior as the :8000 port, except that it expects HTTPS traffic only.
- :8001: Port on which the Admin API used to configure listens.
- :8444: Port on which the Admin API listens for HTTPS traffic.
