Layer7 API Management

Hi Team,

I tried to add a new node to an existing cluster but fiund below error:

[root@explore ~]# cat create-node.properties | /opt/SecureSpan/Gateway/config/bin/ssgconfig-headless create
Exception configuring gateway: Unexpected error saving configuration 'default already exists'

Please help.

Thanks

Pratyush

The log, /opt/SecureSpan/Gateway/config/logs/config.log,  might provide more details

I checked the logs, but i am not understanding any point , please help.

Did you run headless configure on a fresh install gateway (without any configuration), or a configured gateway?

Hi Zhijun,

Thanks for reply. 

I have configured a gateway in my local machine with failover connection. Below are details:

-- 2 Gateway hosts i have configured : gateway1.l7tech.com(Primary Gateway Node) and gateway2.l7tech.com (Secondary Gateway Node) 

-- Then i setup Database Replication Nodes 

--  Configure slave permission on gateway1 for gateway2 user and vice versa.

-- Configured replication on secondary gateway node : gateway1 and gateway2

-- Created primary DB node on gateway1

Once the replication was done then i ran the below command in root shell :

1.)

/opt/SecureSpan/Gateway/config/bin/ssgconfig-headless create -template > create-node.properties

2.) Once the file created then i just edited the properties as per the guide provided by the CA document and now i am stuck with the below error:

[root@gateway1 ~]# cat create-node.properties | /opt/SecureSpan/Gateway/config/bin/ssgconfig-headless create
Exception configuring gateway: Missing configuration property 'database.pass'. Message: This property is needed when configuring a mysql database.
[root@gateway1 ~]#

If i will give the database.pass also then it will throw the same error:  Unexpected error saving configuration 'default already exists'.

Please suggest me what steps i need to perform after the database node replication setup.

Thanks

Pratyush

For Precise answer of your questions answer is below:

Q: Did you run headless configure on a fresh install gateway (without any configuration), or a configured gateway?

A: On Configred gateway.

Hi All,

The issue has been resolved . Thanks much .

Praty

Hi pratysin ,

The headless configuration is for fresh install gateway only(unconfigured gateway), please check the prerequisites,

Auto-Provision a Gateway Node - CA API Gateway - 9.3 - CA Technologies Documentation 

Regards,

Mark

Hi Mark,

Please answer the 2 questions below:

1.) If we need unconfigured gateway, then in pre-requisite why it has been mention like:

-- Database replication should be configured prior to headless configuration, if desired. For more information, see Configuring Cluster Database Replication.

So what un-configured gateway means?

2.) In the document, in Step 2 "Edit the Template File" , what does this means: "Example properties for a database master..."

Thanks much for your patience.

More precisely, it's not "unconfigured gateway", it's "unconfigured gateway node". Configuring gateway node is different with configuring OS or database. The headless script is to configure the gateway node silently.

Your original problem is that the gateway node had been configured, and node.properties already existed.

for stand along gateway, gateway cluster with replicated databases, the node properties are different, that's why we need different property template file, the "Example properties for a database master..." is for gateway node which host the primary database.

Thanks a lot for all the clarifications. It really helped a lot
