Question about solr core creation on <5 about ansible-role-solr HOT 13 CLOSED

Solr 4.4 through 4.10 have automatic core discovery, for these versions you have to:

• create a core directory manually containing conf and data
• manually copy your config into conf (ensure there is no <dataDir> set in solrconfig.xml)
• place core.properties containing name=[your core name] in the core directory

My Ansible playbook for a Solr 4.8.1 server with 3 cores on an EC2 instance looks like this:

---
- hosts: all
  become: yes
  gather_facts: yes

  roles:
    - geerlingguy.java
    - geerlingguy.solr

  vars:
    solr_version: 4.8.1
    cores:
      - app1
      - app2
      - app3

  tasks:
    - name: Mount EBS volume
      mount:
        name: /mnt/solr
        src: /dev/xvdf
        fstype: ext4
        opts: defaults,nofail
        state: present

    - name: Create Solr core
      lineinfile:
        path: "/var/solr/{{ item }}/core.properties"
        regexp: '^name='
        line: 'name={{ item }}'
        create: yes
        owner: solr
        group: solr
        mode: 0644
      with_items: "{{ cores }}"

    - name: Deploy Solr config
      copy:
        src: "files/{{ item }}/solr/"
        dest: "/var/solr/{{ item }}/conf"
        owner: solr
        group: solr
        mode: 0644
      with_items: "{{ cores }}"

    - name: Symlink Solr data
      file:
        src: "/mnt/solr/{{ item }}"
        dest: "/var/solr/{{ item }}/data"
        force: yes
        owner: solr
        group: solr
        state: link
      with_items: "{{ cores }}"

Ok, solr hadn't started properly. Making more sense now.

@fubarhouse - Yeah... I've actually been trying to find a nice simple way to do it for one of my own projects too. It was never super easy to add cores in 3.x/4.x, but the basic way I'm doing it now is:

• use a templated solr.xml file with all the cores listed.
• manually modify the <dataDir> in each core's solrconfig.xml file
• copy things into the right places
• cross fingers and hope it all works!

Can anyone offer a task file that creates a new core from Drupal's search_api_solr config? I had it working for 5 but struggling a bit with 4 - trying to duplicate the Acquia setup.

@simesy have you tried the playbook by @longwave?

You'd need a Solr 4 instace for it to work, but it looks good. You may also need to template a file for the cores.

I'll have anotherlook today - I have not had a lot of Solr 6 success in local drupal development in recent weeks.

Thanks fubarhouse, i'll have a looksee.

Oh you mean up there. yeah i manually tried those steps that failed, but since then I went on a long loop of other things. Going to try again now.

from ansible-role-solr.

I could look into it in that case, the most critical piece is templating a single file with the core configs.

I’ve no problem with templating it, but longer term management isn’t flexible outside of Ansible and as you’ve seen in person our Jenkins workflows capitalise on that flexibility. I haven’t invested in Solr 4 config management yet...

I would use geerlingguy’s recommendation in doing this, but no guarantees though, I’m pressed for time outside work hours at the moment.

Edit: could you provide the output of that playbook? It’s a fantastic starting point!!

from ansible-role-solr.

i think the templating thing is fine, it's installing any core and getting anything to show on http.../solr/ :)

For reference these are my config and rudimentary steps. With:

• assets/core.properties referenced below containing name=MYCORE
• drupal-vm config.yml contains config below
• vagrant up
• sudo /etc/init.d/solr start
• then visit MYSITE.vm:8983/solr/#/MYCORE

  - solr

Thanks @longwave !

Something changed which means i don't need to manually start solr, probably 018d78e
