[jira] [Commented] (SOLR-8296) Cannot find instructions for upgrading from one 5.x release to another

["Shawn Heisey (JIRA)" <ji...@apache.org>]

    [ https://issues.apache.org/jira/browse/SOLR-8296?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=15006958#comment-15006958 ] 

Shawn Heisey commented on SOLR-8296:
------------------------------------

When I asked about this on the IRC channel, Hoss recommended that I open this issue and tag [~thelabdude].

I tried renaming the init script mentioned in the error message, and then it complained that the symlink in /opt already exists.

{code}
ERROR: /opt/solr5 already exists! Please move this directory / link or choose a different service name using the -s option.
{code}

I renamed that symlink and then it installed.  This means I have a workaround, but novice users may not find their way through the problems.

My solr.in.sh was replaced, so I've got problems I need to correct, like the heap size.

> I'm trying to upgrade a Solr install on Linux from 5.2.1.  The current install was installed with the install_solr_service shell script.
> This command doesn't work:
> {code}
> ./install_solr_service.sh /index/src/lucene_solr_5_3/solr/package/solr-5.3.2-SNAPSHOT.tgz -d /index/solr5 -s solr5 -p 8982
> {code}
> I get this message:
> {code}
> ERROR: /etc/init.d/solr5 already exists! Perhaps Solr is already setup as a service on this host?
> {code}
> What I was hoping for was another directory in /opt, the symlink /opt/solr5 changing to point at the new directory, and a new init script, with the installer noticing an existing solr.in.sh and other files in /index/solr5, and not touching them.
> When I installed 5.2.1, I used the same command, with the older install script and the 5.2.1 tarball.
> There is an "Upgrading Solr" section in the reference guide, but it just talks about differences that might require config changes, not an actual procedure.
> I do not know whether we need a separate upgrade script or an upgrade option for the current script.
