Dear team,
I want to upgrade my ES cluster to a newer version.
This is the version I`m using:
According to the bellow page:
I just want to know can I upgrade my cluster with Rolling Upgrade ?
Or which way should I consider to upgrade my cluster and have the service up simultaneously...?
I have a cluster with 4nodes of ES data and 1node of Kibana instance.
Just one another question:
How can I run newer version on a node which older version is running?
my Elasticsearch runs on a CentOS with SysV. I got the new version of Elasticsearch.tar and extracted it in /home/my_user directory and changed the elasticsearch.yml to older version's config specifics.
Disabled shard allocation and also did "sync flush" then stopped older version: service elasticsearch stop
Now I want to run the newer version with the same config file... What should I do?
How can I run new Elasticsearch?
This is elasticsearch.yml of my newer version: (same as the older one)
elasticsearch might not be a problem. but kibana config has change a bit. but it won't be too much hassle. just turn to log file of kibana and it will tell you why it failed.
