文件目录结构如下:
cat memcached_role.yml
- hosts: memcached
remote_user: root roles:
- memcached
cat roles/memcached/vars/main.yml
username: memcached
groupname: memcached
memcached_port:
cat roles/memcached/templates/memcached.j2
PORT="{{ memcached_port }}"
USER="{{ username }}"
MAXCONN=""
CACHESIZE="{{ ansible_memtotal_mb//4 }}"
OPTIONS=""
cat roles/memcached/handlers/main.yml
- name: restart service
service: name=memcached state=restarted
cat roles/memcached/tasks/main.yml
- import_tasks: group.yml
- import_tasks: user.yml
- import_tasks: yum.yml
- import_tasks: templ.yml
- import_tasks: copyfile.yml
- import_tasks: start.yml
cat roles/memcached/tasks/group.yml
- name: create group
group: name={{ username }} system=yes gid=
cat roles/memcached/tasks/user.yml
- name: create user
user: name={{ username }} group={{ groupname }} uid= system=yes shell=/sbin/nologin
cat roles/memcached/tasks/yum.yml
- name: install service
