New Features

An initial version of templating strategy was added to the sourcer.

Upgrade Instructions

These are the upgrade instructions if you upgrade from version 2.2.5. If you are upgrading from an older version (e.g. v2.1.5) please follow the upgrade instructions on Squirro 2.2.0 - Release Notes

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

3. Resolve configurations

The Squirro packages attempt to upgrade *.ini and *.conf configuration files automatically. However if you have made local modifications, the upgrade results in *.rpmnew files that you would need to merge manually. We recommend

backing up the previous *.ini and *.conf files to *.ini.orig and *.conf.orig,
renaming the *.ini.rpmnew and *.conf.rpmnew files to *.ini and *.conf respectively
inspecting all the *.orig files individually and porting any settings manually

Use the following scripts to look for and resolve unresolved configuration files on each cluster node:

# 1. First remember all *.rpmnew because we are about to rename them, but we want to remember the list for step 3 below
sudo su
FILES_TO_RESOLVE=`ls /etc/squirro/*.ini.rpmnew /etc/nginx/conf.d/*.conf.rpmnew /etc/monit.d/*.rpmnew 2> /dev/null | sed -e "s/\.rpmnew//"`
  
# 2. Back up original config files and make the *.rpmnew files the real configuration files
# (\cp and \rm are used to avoid interactive alias of the commands and to ensure that the config file retains the ownership of the original config file)
for CONFIG_FILE in ${FILES_TO_RESOLVE}; do \cp ${CONFIG_FILE} ${CONFIG_FILE}.orig; \cp ${CONFIG_FILE}.rpmnew ${CONFIG_FILE}; \rm ${CONFIG_FILE}.rpmnew; done
  
# 3. Finally merge the commands. Exit vim via :q<enter>:q<enter> to accept a new config files verbatim
for CONFIG_FILE in ${FILES_TO_RESOLVE}; do vim -O ${CONFIG_FILE}.orig ${CONFIG_FILE}; done
