Hi Mark:
Hi, could you start by telling us which version or branch of Kolla Ansible you are using?
root@ubt-1804:~# pip show kolla-ansible Name: kolla-ansible Version: 10.1.0.dev260 I download them via "git clone" , it is master branch by default . git clone https://github.com/openstack/kolla git clone https://github.com/openstack/kolla-ansible
could you try it out and report back? https://review.opendev.org/749463
I will try it later. 在 2020-09-02 16:35:24，"Mark Goddard" <mark@stackhpc.com> 写道： On Tue, 1 Sep 2020 at 15:48, sosogh <sosogh@126.com> wrote: Hi list: I want to use kolla-ansible to deploy openstack , but using external mysql.

Hi, could you start by telling us which version or branch of Kolla Ansible you are using? I have some questions: ################ ## Question 1 ## ################ According to the offical doc , if setting it in inventory file(multinode), kolla-ansible -i ./multinode deploy will throw out error: I guest when kolla-ansible running the playbook against myexternalmariadbloadbalancer.com , the """register: find_custom_fluentd_inputs""" in """TASK [common : Find custom fluentd input config files]""" maybe null . I think this could be an issue with a recent change to the common role, where the condition for the 'Find custom fluentd input config files' task changed slightly. I have proposed a potential fix for this, could you try it out and report back? https://review.opendev.org/749463 ################ ## Question 2 ## ################ According to the offical doc , If the MariaDB username is not root, set database_username in /etc/kolla/globals.yml file: But in kolla-ansible/ansible/roles/xxxxxx/tasks/bootstrap.yml , they use ''' login_user: "{{ database_user }}" ''' ， for example : You are correct, this is an issue in the documentation. I have proposed a fix here: https://review.opendev.org/749464 So at last , I took the following steps: 1. """not""" setting [mariadb] in inventory file(multinode) 2. set "database_user: openstack" for "privillegeduser" PS: My idea is that if using an external ready-to-use mysql (cluster), it is enough to tell kolla-ansible only the address/user/password of the external DB. i.e. setting them in the file /etc/kolla/globals.yml and passwords.yml , no need to add it into inventory file(multinode) I agree, I did not expect to need to change the inventory for this use case. Finally , it is successful to deploy openstack via kolla-ansible . So far I have not found any problems. Are the steps what I took good ( enough ) ? Thank you !
