Upgrade Instructions

These are the upgrade instructions if you upgrade from version 2.2.6. If you are upgrading from an older version e.g. 2.1.5 please follow the upgrade instructions on Squirro 2.2.0 - Release Notes and Squirro 2.2.6 - Release Notes.

This is not the latest version of Squirro. To upgrade to this version, please ensure that you point the squirro yum repository to version '2.3.0' and not to 'latest'.

If you are using Squirro in a Box, then there are additional steps involved. In this case, please contact support.

 

1. Upgrade Storage Nodes

If your storage node runs in the same Virtual Machine or Operating System as your cluster node, skip this step. Otherwise upgrade all storage nodes one at a time by running:

[squirro@storagenode01 ~] sudo yum update

2. Upgrade Cluster Nodes

[squirro@clusternode01 ~] sudo yum update squirro-cluster-node-users
[squirro@clusternode01 ~] sudo yum update

As with this release a new service is added, some additional steps are required.

On a single-cluster-node setup you need to do the following steps on the cluster node:

[squirro@clusternode01 ~] sudo service monit restart
[squirro@clusternode01 ~] sudo service nginx restart

If you run Squirro in a multi-cluster-node environment you need to do the following additional steps on each cluster node:

[squirro@clusternode01 ~] sudo sed -i -e 's/db_endpoint_discovery = false/db_endpoint_discovery = true/' /etc/squirro/trends.ini
[squirro@clusternode01 ~] sudo mkdir /mnt/gv0/trends_data
[squirro@clusternode01 ~] sudo chown sqtrends:squirro /mnt/gv0/trends_data
[squirro@clusternode01 ~] sudo sed '$ a [offline_processing]\ndata_directory = /mnt/gv0/trends_data' -i /etc/squirro/trends.ini
[squirro@clusternode01 ~] sudo service monit restart
[squirro@clusternode01 ~] sudo service nginx restart

 

3. Resolve configurations (if required)

If you have previously edited configuration files manually then consult the Configuration Conflicts section for how to identify and resolve any possible conflicts.
