混合架构服务网格搭建与Istio故障排除指南

1. 虚拟机上搭建演示应用

在虚拟机（VM）上搭建演示应用，模拟VM工作负载，用于测试整体设置，步骤如下：
1. 在VM上设置Envoy
- 安装Envoy ：

$ sudo apt update
$ sudo apt install debian-keyring debian-archive-keyring apt-transport-https curl lsb-release
$ curl -sL 'https://deb.dl.getenvoy.io/public/gpg.8115BA8E629CC074.key' | sudo gpg --dearmor -o /usr/share/keyrings/getenvoy-keyring.gpg
# 验证密钥环 - 应输出 "OK"
$ echo a077cb587a1b622e03aa4bf2f3689de14658a9497a9af2c427b­ba5f4cc3c4723 /usr/share/keyrings/getenvoy-keyring.gpg | sha256sum --check
$ echo "deb [arch=amd64 signed-by=/usr/share/keyrings/getenvoy-keyring.gpg] https://deb.dl.getenvoy.io/public/deb/debian $(lsb_release -cs) main" | sudo tee /etc/apt/sources.list.
