Gateway on Red Hat (RHEL) / CentOS
Ansible is required to run the following commands. Instructions on how install Tyk Gateway with shell is in the Shell tab.
- clone the tyk-ansible repositry
$ git clone https://github.com/TykTechnologies/tyk-ansible
cdinto the directory
$ cd tyk-ansible
- Run initalization script to initialize environment
$ sh scripts/init.sh
hosts.ymlfile to update ssh variables to your server(s). You can learn more about the hosts file here
Run ansible-playbook to install
$ ansible-playbook playbook.yml -t tyk-gateway
Install Tyk API Gateway on Red Hat
Tyk has it’s own signed RPMs in a YUM repository hosted by the kind folks at packagecloud.io, which makes it easy, safe and secure to install a trusted distribution of the Tyk Gateway stack.
This tutorial will run on an Amazon AWS Red Hat Enterprise Linux 7.1 instance. We will install Tyk Gateway with all dependencies stored locally.
We’re installing on a
t2.micro because this is a tutorial, you’ll need more RAM and more cores for better performance.
This configuration should also work (with some tweaks) for CentOS.
- Ensure port
8080is open: this is used in this guide for Gateway traffic (API traffic to be proxied)
Step 1: Set up YUM Repositories
First, we need to install some software that allows us to use signed packages:
sudo yum install pygpgme yum-utils wget
Next, we need to set up the various repository configurations for Tyk and MongoDB:
Step 2: Create Tyk Gateway Repository Configuration
Create a file named
/etc/yum.repos.d/tyk_tyk-gateway.repo that contains the repository configuration below https://packagecloud.io/tyk/tyk-gateway/install#manual-rpm:
[tyk_tyk-gateway] name=tyk_tyk-gateway baseurl=https://packagecloud.io/tyk/tyk-gateway/el/7/$basearch repo_gpgcheck=1 gpgcheck=1 enabled=1 gpgkey=https://keyserver.tyk.io/tyk.io.rpm.signing.key.2020 https://packagecloud.io/tyk/tyk-gateway/gpgkey sslverify=1 sslcacert=/etc/pki/tls/certs/ca-bundle.crt metadata_expire=300
Step 3: Install EPEL
EPEL (Extra Packages for Enterprise Linux) is a free, community based repository project from Fedora which provides high quality add-on software packages for Linux distribution including RHEL, CentOS, and Scientific Linux. EPEL isn’t a part of RHEL/CentOS but it is designed for major Linux distributions. In our case we need it for Redis, run this command to get it. Full instructions available here http://fedoraproject.org/wiki/EPEL#How_can_I_use_these_extra_packages.3F:
sudo yum install -y epel-release sudo yum update
Finally we’ll need to update our local cache, so run:
sudo yum -q makecache -y --disablerepo='*' --enablerepo='tyk_tyk-gateway' --enablerepo=epel
Step 4: Install Packages
We’re ready to go, you can now install the relevant packages using yum:
sudo yum install -y redis tyk-gateway
(you may be asked to accept the GPG key for our two repos and when the package installs, hit yes to continue)
Step 5: Start Redis
In many cases Redis will not be running, so let’s start those:
sudo service redis start
When Tyk is finished installing, it will have installed some init scripts, but it will not be running yet. The next step will be to setup the Gateway – thankfully this can be done with three very simple commands.
Configure Tyk Gateway with the Dashboard
This configuration assumes that you have already installed Tyk Dashboard, and have decided on the domain names for your Dashboard and your Portal. They must be different. For testing purposes, it is easiest to add hosts entries to your (and your servers)
Set up Tyk
You can set up the core settings for Tyk Gateway with a single setup script, however for more involved deployments, you will want to provide your own configuration file.
You need to replace
--redishost=<hostname>with your own value to run this script.
sudo /opt/tyk-gateway/install/setup.sh --dashboard=1 --listenport=8080 --redishost=<hostname> --redisport=6379
What we’ve done here is told the setup script that:
--dashboard=1: We want to use the Dashboard, since Tyk Gateway gets all it’s API Definitions from the Dashboard service, as of v2.3 Tyk will auto-detect the location of the dashboard, we only need to specify that we should use this mode.
--listenport=8080: Tyk should listen on port 8080 for API traffic.
--redishost=<hostname>: Use Redis on the hostname: localhost.
--redisport=6379: Use the default Redis port.
The Tyk Gateway can be started now that it is configured. Use this command to start the Tyk Gateway:
sudo service tyk-gateway start
Pro Tip: Domains with Tyk Gateway
Tyk Gateway has full domain support built-in, you can:
- Set Tyk to listen only on a specific domain for all API traffic.
- Set an API to listen on a specific domain (e.g. api1.com, api2.com).
- Split APIs over a domain using a path (e.g. api.com/api1, api.com/api2, moreapis.com/api1, moreapis.com/api2 etc).
- If you have set a hostname for the Gateway, then all non-domain-bound APIs will be on this hostname + the
