Hello guys !
I have the following role created:
- name: Recover
block:
- name: Starts the first node of the cluster in bootstrap mode
shell: /etc/init.d/mysql bootstrap-pxc
when: inventory_hostname == groups.CD5525[0]
become: yes
register: return_out
- name: Start the rest of nodes
systemd:
state: started
name: mysql
when: inventory_hostname != groups.CD5525[0]
become: yes
register: screen_out
- name: Stop the bootstrapped node to restart it in normal state
shell: service mysql bootstrap-stop
when: inventory_hostname == groups.CD5525[0]
become: yes
register: screen_out
- name: Start the first node in normal status
systemd:
state: started
name: mysql
when: inventory_hostname == groups.CD5525[0]
become: yes
register: screen_out
rescue:
- name: Print when errors
debug:
msg: "Found an error, can not continue ! {{ansible_failed_task}}"
any_errors_fatal: true
I have three nodes.
I need to control the failure on the first node but the rescue section is
not executed until I receive failures from all the nodes.
Went through the documentation and different posts but did not find a
conclusion about how this works with more than one node or, perhaps, I'm
doing something wrong.
Your comments are welcome, thank you.
