在 《如何快速迁移传统 LB 公网业务到 Serverless?》 文章中，为大家介绍了负载均衡 CLB 触发器接入 Serverless 函数的优势、适用场景及配置指引。

\n

在本篇文章中，将实践如何使用负载均衡 CLB 作为 Serverless 服务的访问入口，拓展其低成本、免运维等优势，为开发者平滑迁移应用上云提供参考。

\n

创建云函数 SCF

\n
    \n
  1. 进入云函数控制台，点击 “新建” 进行函数创建。
    2. \n
\n

函数控制台地址：https://console.cloud.tencent.com/scf/list

\n\n
    \n
  1. 选择自定义模版进行创建，运行环境设置为 “Python3.6” ，选择 “本地上传文件夹” ，下载 Demo 内容，成功下载后，需进行解压，在 “函数代码” 中上传整个本地文件夹。
    2. \n
  2. 执行方法：index.main_handler
    3. \n
  3. Demo 下载地址：https://scfdemo-1253970226.cos.ap-chengdu.myqcloud.com/21_3_17_daxigua.zip
    4. \n
\n\n
    \n
  1. 完成后即可在函数控制台对相关代码进行自定义编辑。
    2. \n
\n\n

创建负载均衡 CLB 资源

\n
    \n
  1. 进入负载均衡 CLB 控制台，点击 “新建” 进行资源创建。
    2. \n
\n

CLB 控制台地址：https://console.cloud.tencent.com/clb/instance?rid=1

\n\n
    \n
  1. 选择云函数支持的负载均衡实例。
    2. \n
\n\n
\n

注：目前云函数支持绑定网络类型为“公网”、网络为 “私有网络” 的同地域实例，监听器支持 “七层监听器” ，暂不支持四层监听器。

\n
\n
    \n
  1. 创建监听器。
    2. \n
\n\n
    \n
  1. 在 CLB 控制台或云函数控制台绑定 SCF 实例资源。
    2. \n
\n\n\n
    \n
  1. 访问 CLB 监听器路径，查看整体效果（体验地址：http://129.226.10.72:81/daxigua）。
    2. \n
\n\n \n

方案总结

\n

通过 CLB 监听器访问路径，可以快速拓展 Serverless 应用的访问及使用场景。为开发者提供高可用的 Serverless 应用访问服务。
