User Authentication and xpack problem starting Elasticsearch


(Ian Robertson) #1

I have re-booted my cluster, but when I try to cat my nodes I get the following error:

{"error":{"root_cause":[{"type":"security_exception","reason":"failed to authenticate user [elastic]","header":{"WWW-Authenticate":"Basic realm=\"security\" charset=\"UTF-8\""}}],"type":"security_exception","reason":"failed to authenticate user [elastic]","header":{"WWW-Authenticate":"Basic realm=\"security\" charset=\"UTF-8\""}},"status":401}

Additionally, on re-boot I keep getting the following in my logs (Note: a ps -ef shows that the ES port is started)

I am under the impression that this is a license issue where the license needs to get re-loaded, etc...what would you advise as the best path forward from here?

I also just hit this upon deploying via kubernetes, hosted in aws.

I am getting the same exception Running ES 2 nodes in a dev environment after I installed xpack on 1 node.

I'm new to ES deployments so testing with ES 5.0.0-rc1 on mine and another developers windows machines.
Both nodes were seeing each other nicely until I installed xpack. Now they appear to be running but they don't report as being in the same cluster anymore.

Not sure its user authentication related though as I have configured xpack.security.enabled: false. Node with xpack installed shows the following in the log.

Anyone got any progress on this ?

The solution for us had to do with the RHEL 7 Firewall. You need to make sure that the port/protocol is not being blocked. In our case by checking FirewallD:

firewall-cmd --zone=<zone> --query-port=<port>/<protocol>

For example:
firewall-cmd --zone=private --query-port=9305/tcp

From here you can either create a new rule per the zone or turn off FirewallD

Ok I have started again with 2 nodes running locally.
2 ES 5.0.0-rc1 in separate folders with http.port: 9201 configured in second along with host:9301 in the unicast discovery config.
This works fine, the 2 nodes find each other and form a cluster. So surely this rules out firewall and port issues ?

The problem starts when I install x-pack on 1 node. and restart it.
Log file reports that it detects the master, the other node and has started... but then immediately after it reports master_left, reason failed to ping 3 times... then I see the exporter warnings and exceptions again and the node fails to start.

I also tried bringing down both nodes and installing x-pack on both, then bring back up and it worked.
Is it possible to push out x-pack in a rolling deployment or does it require a whole cluster restart ?


(Jay Modi) #6

x-pack installation requires a full cluster restart.


(Tim Mori) #7

Running into the same issue. It seems that X-pack implements some basic authentication, so you have to configure your curl commands to include the login.

curl -u elastic -XGET 'http://localhost:9200/_cat/health?v'

Default password is changeme. There's a doc on changing passwords:
