本文为您介绍如何通过Ansible ali_ros_stack模块调用ROS的API接口部署LNMP（Linux+Nginx+MySQL+PHP）环境实例。
前提条件
确保您已经在Linux系统使用pip3安装并配置了Ansible模块，详情请参见安装和配置Ansible。
操作步骤
- 创建一个名称为create_lnmp.yml的文件，然后通过VI编辑器打开。
vi create_lnmp.yml - 在编辑模式下，将以下完整的playbook示例代码粘贴到create_lnmp.yml文件中。
说明 ali_ros_stack模块参数详情，请参见 参数说明。

- 创建一个名称为create_lnmp_instance.json的文件，然后通过VI编辑器打开。
vi create_lnmp_instance.json - 在编辑模式下，将以下完整的playbook示例代码粘贴到create_lnmp_instance.json文件中。
