I am new to elasticsearch and following the tutorial here:
I have hit a stumbling block as I can connect the servers with the ELK stack configured with the the server that is logging activity to file beat.
I have narrowed it down to an issue with the SSL certificates copied from the ELK server as when i check /var/log/messages I get the following error:
usr/bin/filebeat: transport.go:125: SSL client failed to connect with: x509: certificate signed by unknown authority (possibly because of "crypto/rsa: verification error" while trying to verify candidate authority certificate "serial:16193853809450343771")
How ever, the keys have been copied over and these files are the same on both servers :
When I try to read the syslogs, I get this:
sudo tail /var/log/syslog | grep filebeat:
tail: cannot open ‘/var/log/syslog’ for reading: No such file or directory.
I will appreciate any pointers on this
