ansible自动化部署zabbix客户端
zabbix_client_install.yml内容# cat /etc/ansible/roles/zabbix_client_install.yml
---
- hosts: pltest
remote_user: root
gather_facts: True
roles:
- zabbix_client_install
files包含在不同平台上已经编译好的zabbix客户端程序
handlers目录下定义了配置文件发生变化后触发重启进程(notify)
# cat /etc/ansible/roles/zabbix_client_install/handlers/main.yml
- name: restart zabbix_agentd
service: name=zabbix_agentd state=restarted
tasks下角色的任务列表
# cat /etc/ansible/roles/zabbix_client_install/tasks/main.yml
- include: copy.yml
- include: install.yml
- include: delete.yml
copy.yml文件中使用tags定义标签，when语句判断os版本，复制对应版本的客户端程序。
tags用于让用户选择运行或路过playbook中的部分代码。ansible具有幂等性，因此会自动跳过没有变化的部分，即便如此，有些代码为测试其确实没有发生变化的时间依然会非常地长。此时，如果确信其没有变化，就可以通过tags跳过此些代码片断。
在task后添加when子句即可使用条件测试；when语句支持Jinja2表达式语法。
when语句中还可以使用facts或playbook中定义的变量。
