Squirro can be upgraded using the YUM package manager.
Before you start the upgrade, you must ensure that the Elasticsearch cluster is in a 'green' state.
To validate the state, log into one of the hosts that have the squirro-storage-node package installed and run the following command:
curl -XGET 'http://localhost:9200/_cluster/health?pretty=true' |
The output looks like this:
{
"cluster_name" : "squirro-26aa394e-56ee-4274-b094-5075bb94d892",
"status" : "green",
"timed_out" : false,
"number_of_nodes" : 1,
"number_of_data_nodes" : 1,
"active_primary_shards" : 14,
"active_shards" : 14,
"relocating_shards" : 0,
"initializing_shards" : 0,
"unassigned_shards" : 0,
"delayed_unassigned_shards" : 0,
"number_of_pending_tasks" : 0,
"number_of_in_flight_fetch" : 0,
"task_max_waiting_in_queue_millis" : 0,
"active_shards_percent_as_number" : 100.0
} |
Check for the status on line 3. e.g. in this case:
"status": "green" |
Do not proceed with the upgrade if the state is yellow or red. |
If you haven't already done an update, please contact squirro support to obtain a new, unique user and password to enable you to upgrade. You only need to do the following once for your Squirro Box:
sudo su USER=<user you received from Squirro Support> PASSWORD=<password you received from Squirro Support> sed -e "s/squirro::yum_repo_user : contact-squirro-support/squirro::yum_repo_user : $USER/" -i /etc/puppet/hieradata/local.yaml sed -e "s/squirro::yum_repo_password: contact-squirro-support/squirro::yum_repo_password: $PASSWORD/" -i /etc/puppet/hieradata/local.yaml . /etc/puppet/modules/puppet/files/puppetrun |
To upgrade Squirro, use the yum update command:
[root@localhost ~]# yum update |
