This section describes various ways to validate that the Apigee mTLS installation was successful. You can also use the techniques described in this section when troubleshooting issues with the cluster.
Validate the iptables configuration
You can validate that the
apigee-mtls installation was successful by checking that
iptables routes are working and that the rules are valid.
Before validating an
iptables configuration, be sure that:
- You uninstalled firewalld from the node and replaced it with iptables, as described in Replace the default firewall.
- You stopped all Apigee components on the node, including
To validate the apigee-mtls configuration was successful with iptables:
- Log in to a node in your cluster. The order in which you do this does not matter.
- Stop all components on the node, as the following example shows:
- Execute the
validatecommand, as the following example shows:
iptablessends messages to every port that either Consul or the local Apigee services use. If the script encounters an invalid rule or a failed route, it displays an error.
If any Apigee services or Consul servers are running on the node, then this command will fail.
- Start the
apigee-mtlscomponent before all other components on the node by executing the following command:
/opt/apigee/apigee-service/bin/apigee-service apigee-mtls start
- Start the remaining Apigee components on the node in the
start order, as the
following example shows:
/opt/apigee/apigee-service/bin/apigee-service component_name start
- Repeat these steps on all nodes in the cluster. Ideally, do this on all nodes within 5 minutes of having started on the first node.
Verify the remote proxy status
You can use Consul on ZooKeeper nodes to check if the ingress and egress proxy services on all nodes are alive, healthy, and have joined the service mesh.
To check the proxy status of your nodes:
- Log in to a node that is running ZooKeeper.
- Execute the following command:
systemctl status consul_server
Verify the quorum status
The mTLS installation includes adding the Consul proxy services to all nodes. As a result, you should verify the quorum status of all ZooKeeper nodes.
To check the quorum status, log in to each node running ZooKeeper and execute the following command:
/opt/apigee/apigee-mtls-consul/bin/consul operator raft list-peers
This command displays a list of the Consul instances and their statuses, as the following example shows:
Node ID Address State Voter RaftProtocol prc-test-0-1619 b59c1f44-6eb0-81d4-42 10.126.0.98:8300 leader true 3 prc-test-1-1619 a4372a6e-8044-e587-43 10.126.0.146:8300 follower true 3 prc-test-2-1619 71eb181f-4242-5353-44 10.126.0.100:8300 follower true 3

In addition, you can get information about the cluster's health, including whether the cluster's quorum has formed and if remote members are impairing functionality. To do this, use the following command:
/opt/apigee/apigee-service/bin/apigee-service apigee-mtls status
