关于prometheus，grafana，kiali，zipkin更详细的安装方法可以查看博客《Istio(三)：服务网格istio可观察性：Prometheus,Grafana,Zipkin,Kiali》https://www.cnblogs.com/renshengdezheli/p/16836943.html
#方法一：[root@k8scloude1 ~]# kubectl apply -f https://raw.githubusercontent.com/istio/istio/release-1.14/samples/addons/prometheus.yaml[root@k8scloude1 ~]# kubectl apply -f https://raw.githubusercontent.com/istio/istio/release-1.14/samples/addons/grafana.yaml[root@k8scloude1 ~]# kubectl apply -f https://raw.githubusercontent.com/istio/istio/release-1.14/samples/addons/kiali.yaml[root@k8scloude1 ~]# kubectl apply -f https://raw.githubusercontent.com/istio/istio/release-1.14/samples/addons/extras/zipkin.yaml #方法二：下载istio安装包istio-1.14.3-linux-amd64.tar.gz安装分析工具[root@k8scloude1 ~]# ls istio* -distio-1.14.3istio-1.14.3-linux-amd64.tar.gz[root@k8scloude1 ~]# cd istio-1.14.3/[root@k8scloude1 addons]# pwd/root/istio-1.14.3/samples/addons[root@k8scloude1 addons]# lsextrasgrafana.yamljaeger.yamlkiali.yamlprometheus.yamlREADME.md[root@k8scloude1 addons]# kubectl apply -f prometheus.yaml[root@k8scloude1 addons]# kubectl apply -f grafana.yaml[root@k8scloude1 addons]# kubectl apply -f kiali.yaml [root@k8scloude1 addons]# ls extras/prometheus-operator.yamlprometheus_vm_tls.yamlprometheus_vm.yamlzipkin.yaml[root@k8scloude1 addons]# kubectl apply -f extras/zipkin.yaml

如果你在安装 Kiali 的时候发现以下错误 No matches for kind "MonitoringDashboard" in version "monitoring.kiali.io/v1alpha1" 请重新运行以上命令 。
prometheus，grafana，kiali，zipkin被安装在istio-system命名空间下，我们可以使用 getmesh istioctl dashboard kiali 打开 Kiali界面 。
我们使用另外一种方法打开Kiali界面：
#可以看到prometheus，grafana，kiali，zipkin被安装在istio-system命名空间下[root@k8scloude1 addons]# kubectl get pod -n istio-systemNAMEREADYSTATUSRESTARTSAGEgrafana-6c5dc6df7c-cnc9w1/1Running227histio-egressgateway-58949b7c84-k7v6f1/1Running810distio-ingressgateway-75bc568988-69k8j1/1Running63d21histiod-84d979766b-kz5sd1/1Running1410dkiali-5db6985fb5-8t77v1/1Running03m25sprometheus-699b7cc575-dx6rp2/2Running82d21hzipkin-6cd5d58bcc-hxngj1/1Running117h#可以看到kiali这个service的类型为ClusterIP，外部环境访问不了[root@k8scloude1 addons]# kubectl get service -n istio-systemNAMETYPECLUSTER-IPEXTERNAL-IPPORT(S)AGEgrafanaNodePort10.100.151.232<none>3000:31092/TCP27histio-egressgatewayClusterIP10.102.56.241<none>80/TCP,443/TCP10distio-ingressgatewayLoadBalancer10.107.131.65192.168.110.19015021:30093/TCP,80:32126/TCP,443:30293/TCP,31400:30628/TCP,15443:30966/TCP10distiodClusterIP10.103.37.59<none>15010/TCP,15012/TCP,443/TCP,15014/TCP10dkialiClusterIP10.109.42.120<none>20001/TCP,9090/TCP7m42sprometheusNodePort10.101.141.187<none>9090:31755/TCP2d21htracingClusterIP10.101.30.10<none>80/TCP17hzipkinNodePort10.104.85.78<none>9411:30350/TCP17h#修改kiali这个service的类型为NodePort，这样外部环境就可以访问kiali了#把type: ClusterIP 修改为 type: NodePort即可[root@k8scloude1 addons]# kubectl edit service kiali -n istio-systemservice/kiali edited#现在kiali这个service的类型为NodePort，浏览器输入物理机ip:30754即可访问kiali网页了[root@k8scloude1 addons]# kubectl get service -n istio-systemNAMETYPECLUSTER-IPEXTERNAL-IPPORT(S)AGEgrafanaNodePort10.100.151.232<none>3000:31092/TCP27histio-egressgatewayClusterIP10.102.56.241<none>80/TCP,443/TCP10distio-ingressgatewayLoadBalancer10.107.131.65192.168.110.19015021:30093/TCP,80:32126/TCP,443:30293/TCP,31400:30628/TCP,15443:30966/TCP10distiodClusterIP10.103.37.59<none>15010/TCP,15012/TCP,443/TCP,15014/TCP10dkialiNodePort10.109.42.120<none>20001:30754/TCP,9090:31573/TCP8m42sprometheusNodePort10.101.141.187<none>9090:31755/TCP2d21htracingClusterIP10.101.30.10<none>80/TCP17hzipkinNodePort10.104.85.78<none>9411:30350/TCP17h
