add feature upgrade existing solr installation about ansible-role-solr HOT 8 CLOSED

@geerlingguy Would you be open to a PR on this? I'd envision an approach like stating solr_install_path to test if it's a symlink to the same or different version than solr_version, or I suppose just call bin/solr version on the installed solr, which should work for pre5 and 5+. Then run the install script with the -f upgrade flag if they're different instead of relying on creates with the solr executable to detect if it's already there.

I managed to upgrade by adding these as pre_tasks, controlled by the solr_force_reinstall variable:

- name: Remove existing install
  file:
    path: /opt/solr
    state: absent
  when: solr_force_reinstall
- name: Remove existing install
  file:
    path: /etc/init.d/solr
    state: absent
  when: solr_force_reinstall
- name: Remove existing install
  file:
    path: /etc/default/solr.in.sh
    state: absent
  when: solr_force_reinstall

Yes we'd like this. Not sure how to upgrade with this role as is. Just delete /opt/solr?

@jbilbro - Yeah, basically. Be aware that if you upgrade major versions, that can cause strange things to happen to existing indexes in SOLR_HOME.

I would like to support more easily switching versions, though. So far I typically support slightly older installs, so I haven't had to manage many servers that are running the bleeding edge (and thus, this hasn't been a priority for me) :(

@mberkowski I'd be open to you forking the repo to add this regardless ;)

just thought I'd add a little extra note. I just successfully upgraded from 7.3 to 7.4 by commenting out the task Remove the downloaded Solr archive. and the condition when: solr_install_path_status.stat.isdir is not defined on the task Download Solr.. I ran the play and then ssh'd into the machine I deployed to. Then ran /root/solr-7.4.0/bin/install_solr_service.sh solr-7.4.0.tgz -n -f from the root user. The -n was probably not necessary. That prevents solr from starting up after install. Now I didn't have any documents in my core when I did the upgrade, so that's a caveat. Thanks.
