istio1.0安装
1. istio1.0安装 创建 istio 目录 [root@centos-110 ~]# mkdir istio [root@centos-110 ~]# cd istio 1.1 获取安装包 链接：https://pan.baidu.com/s/1HQsXvN3Rgo5F7C9XYkhZng 提取码：uqwk 解压： tar -zxvf istio-1.0.0-linux.tar.gz 1.2 安装istioctl cp istio-1.0.0/bin/istioctl /usr/local/bin/ 验证istioctl 安装成功 [root@test2 istio]# istioctl version Version: 1.0.0 GitRevision: 3a136c90ec5e308f236e0d7ebb5c4c5e405217f4 User: root@71a9470ea93c Hub: gcr.io/istio-release GolangVersion: go1.10.1 BuildStatus: Clean 需要先拉取镜像： docker pull daocloud.io/liukuan73/proxy_init:1.0.0 docker pull daocloud.io/liukuan73/galley:1.0.0 docker pull daocloud.io/liukuan73/mixer:1.0.0 docker pull daocloud.io/liukuan73/proxyv2:1.0.0 docker pull daocloud.io/liukuan73/pilot:1.0.0 docker pull daocloud.io/liukuan73/citadel:1.0.0 docker pull daocloud.io/liukuan73/servicegraph:1.0.0 docker pull daocloud.io/liukuan73/sidecar_injector:1.0.0 docker pull daocloud.io/liukuan73/istio-grafana:1.0.0 docker pull daocloud.io/liukuan73/hyperkube:v1.7.6_coreos.0 给镜像重新打标签，保证和下面步骤中istio-demo.yaml里面的镜像保持一致 docker tag daocloud.io/liukuan73/proxy_init:1.0.0 gcr.io/istio-release/proxy_init:1.0.0 docker tag daocloud.io/liukuan73/hyperkube:v1.7.6_coreos.0 quay.io/coreos/hyperkube:v1.7.6_coreos.0 docker tag daocloud.io/liukuan73/galley:1.0.0 gcr.io/istio-release/galley:1.0.0 docker tag daocloud.io/liukuan73/proxyv2:1.0.0 gcr.io/istio-release/proxyv2:1.0.0 docker tag daocloud.io/liukuan73/istio-grafana:1.0.0 gcr.io/istio-release/grafana:1.0.0 docker tag daocloud.io/liukuan73/mixer:1.0.0 gcr.io/istio-release/mixer:1.0.0 docker tag daocloud.io/liukuan73/pilot:1.0.0 gcr.io/istio-release/pilot:1.0.0 docker tag daocloud.io/liukuan73/citadel:1.0.0 gcr.io/istio-release/citadel:1.0.0 docker tag daocloud.io/liukuan73/servicegraph:1.0.0 gcr.io/istio-release/servicegraph:1.0.0 docker tag daocloud.io/liukuan73/sidecar_injector:1.0.0 gcr.io/istio-release/sidecar_injector:1.0.0 注意：这个时候不能把原先的镜像给删除，删除原来镜像后，之后打的标签镜像也会跟着删除 1.3 部署istio 1.3.1、安装Istio的CRD（Custom Resource Definitions） kubectl apply -f /root/istio/istio-1.0.0/install/kubernetes/helm/istio/templates/crds.yaml 1.3.2、安装Istio - Sidecars之间不启用TLS认证 kubectl apply -f /root/istio/istio-1.0.0/install/kubernetes/istio-demo.yaml 注意： 启动文件默认配置的通过外部LoadBalancer访问istio-ingressgateway， 如果没有外部LoadBalancer，需要修改启动文件使用NodePort访问istio-ingressgateway：sed -i 's/LoadBalancer/NodePort/g' /root/istio/istio-1.0.0/install/kubernetes/istio-demo.yaml
本实验需要先修改为NodePort然后再执行上面的操作 1.3.3 验证安装是否成功 查看是否所有服务和pod都正常：发现有两个不正常，没有影响的，
