Hi,
try use handler:
- stat: path=/mnt/mysql
register: p
- name: Create /mnt/mysql directory for database
file:
path: /mnt/mysql
state: directory
mode: 0750
owner: mysql
group: mysql
when: not p.stat.exists
notify:
- create database
handlers:
- name: create database
command: mysql_install_db --user=mysql --datadir=/mnt/mysql
First time, there will not be /mnt/mysql, so we will create it in second
task. It has changed state, therefore we will call handler and create a
database. To be sure, we will skip it every time, the path already exists.
