Re: Knox Gateway Start fail

Can you also provide what you find in /var/log/knox/gateway.log

Re: Knox Gateway Start fail

You mention Knox 0.6.0 however the path shows 0.5.0. For Java it will also help to know whether you are using Oracle or OpenJDK. To address these questions, please also provide the output of:

hdp-select versions
hdp-select status knox-server
rpm -qa | grep knox
java -version

Re: Knox Gateway Start fail

and /var/log/knox/gateway.out if it isn't empty while you are collecting things.

Re: Knox Gateway Start fail

@Kevin Minder it is empty

Re: Knox Gateway Start fail

@Alex Miller Knox version ambari it shows as knox : 0.6.0.2.3 and java is openJDK

hdp-select versions

2.3.4.0-3485

hdp-select status knox-server

knox-server - 2.3.4.0-3485

rpm -qa | grep knox

Re: Knox Gateway Start fail

Expert Contributor

The Error message in /var/log/knox/gateway.log says that the certificate used by Knox will be valid starting in the future:

Failed to start gateway: org.apache.hadoop.gateway.services.ServiceLifecycleException: Gateway SSL Certificate is not yet valid. Server will not start.

-> "not yet valid"

Knox refuses to start, because using such a certificate will result in an SSL exception for almost any client.

You will need to check the certificate your are using for Knox. This is stored as gateway-identity in gateway.jks under /var/lib/knox/data*/keystore

Please refer to this:

http://knox.apache.org/books/knox-0-6-0/user-guide.html#Management+of+Security+Artifacts

What also should work is, if you simply remove the gateway-identity from the keystore, upon start Knox should create a self-signed certificate for you.

Could you share how the certificate was generated? Did you change it after the install? Are you using ntp?

Re: Knox Gateway Start fail

Renew Knox Gateway SSL certificate following the link:

http://www-01.ibm.com/support/docview.wss?uid=swg21987527

Re: Knox Gateway Start fail

Hi


rename the file gateway.jks mv /var/lib/knox/data-2.6.4.0-91/security/keystores/gateway.jks /var/lib/knox/data-2.6.4.0-91/security/keystores/gateway.jks.bck

when you start the know instance it will create a new certificate.


Best,
