安装istio
- 从1.5版本开始将Pilot、Citadel、Galley、Mixer整合成为了istiod，这也就意味着istio服务端由一个组件组成
一、下载istioctl命令行工具
1.打开官方github选择需要的版本
https://github.com/istio/istio/releases
2.下载压缩包
wget https://github.com/istio/istio/releases/download/1.12.0/istio-1.12.0-linux-amd64.tar.gz
3.解压并进入
tar xf istio-1.12.0-linux-amd64.tar.gz
cd istio-1.12.0
4.将istioctl放入/usr/local/bin/
cp bin/istioctl /usr/local/bin/
二、选择合适的配置安装istio
-
istio安装时需要选择合适的配置 这些配置的区别在于关联组件的选择及istiod的配置
-
自定义安装参考：官方文档
1.生成生产配置
istioctl manifest generate --set profile=default > generated-manifest.yaml
2.安装
kubectl apply -f generated-manifest.yaml
三、可视化及监控组件安装
- 安装链路监控及网格监控
kubectl apply -f samples/addons
四、就绪检查及可视化服务
1.检查组件是否成功运行
kubectl get pod -n istio-system
NAME READY STATUS RESTARTS AGE
grafana-68cc7d6d78-94qrh 1/1 Running 0 17d
istio-ingressgateway-8577c57fb6-hdfnl 1/1 Running 0 17d
istiod-5847c59c69-krf9g 1/1 Running 0 17d
jaeger-5d44bc5c5d-wpl62 1/1 Running 0 17d
kiali-fd9f88575-tm2hq 1/1 Running 0 17d
prometheus-77b49cb997-bfhxf 2/2 Running 0 17d
2.将 kiali、tracing svc 修改为 nodeport 类型，以便访问
kubectl get svc -n istio-system
