Sidehistorik
I Installed the ELK stacks as usual:
Kodeblok |
---|
sudo apt-get install openjdk-8-jdk
wget -qO - https://packages.elastic.co/GPG-KEY-elasticsearch | sudo apt-key add -
echo "deb https://artifacts.elastic.co/packages/5.x/apt stable main" | sudo tee -a /etc/apt/sources.list.d/elasticsearch-5.x.list
sudo apt-get update && sudo apt-get install elasticsearch |
But , but then I had to add nodes. A lot of google gave a lot of more og less usefull hints, so here is what i did:
...
Secondly, I changed the same on the next node (elkserver2) and added the IP on elkserver1 in the /etc/elasticseach/elasticseach.yml, changing:
Kodeblok |
---|
discovery.zen.ping.unicast.hosts: ["host1","host1"] |
...
Kodeblok |
---|
discovery.zen.ping.unicast.hosts: ["77.243.52.135","77.243.52.155","77.243.52.153"] |
Then started ES with:
Kodeblok |
---|
service eleaticsearch restart tail -f /var/log/elasticsearch/mos-eisley.log |
But the node never connected to the clustedcluster.
After a short part of troubleshooting, ES only listens pr. default on 127.0.0.0:9200, so in /etc/elasticseach/elasticseach.yml do change
...
Kodeblok |
---|
network.host: 0.0.0.0 |
After successfull join, I changed:
Kodeblok |
---|
discovery.zen.ping.unicast.hosts: ["77.243.52.135"] |
to
Kodeblok |
---|
discovery.zen.ping.unicast.hosts: ["77.243.52.135","77.243.52.155"] |
on both nodes.
For the 3rd node (elkserver3), the trickt was the same, and in the end, the /etc/elasticseach/elasticseach.yml had:
Kodeblok |
---|
discovery.zen.ping.unicast.hosts: ["77.243.52.135","77.243.52.155","77.243.52.153"] |
On all servers, giving me:
