I will update mariadb to 10.1.20 in #16

1st failure has been resolved by upverison of mariadb.

Remained two tasks still fail:

- name: Stop mysql
  service:
    name: mariadb
    state: stopped
  changed_when: true
  listen: Bootstrap cluster
  when:
    - not galera_cluster_ready | bool

- name: Start new cluster
  command: /usr/local/bin/galera_new_cluster
  failed_when: not start_new_cluster.rc in [0, 3]
  changed_when: start_new_cluster.rc == 3
  register: start_new_cluster
  delegate_to: "{{ galera_server_bootstrap_node }}"
  run_once: true
  when:
    - not galera_cluster_ready | bool
  listen: Bootstrap cluster

• Workaround

ln -s  /lib/systemd/system/mysqld.service /lib/systemd/system/mariadb.service
ln -s /etc/ansible/roles/galera_server/files/galera_new_cluster /usr/local/bin/galera_new_cluster

Need to check the ansible task which are responsible for these file copying work.
