做网站需要绑定电脑ip吗win7优化大师好不好
1、背景：
因公司业务需要，需要在测试、生产kubernetes集群中部署elasticsearch集群，因不同环境要求，需要部署不同模式的elasticsearch集群，
1、测试环境因安全性要求不高，是部署一套默认配置；
2、生产环境因安全性要求，是部署一套带认证配置；
2、开发elasticsearch集群，无认证模式：
在kubernetes集群中部署elasticsearch集群，采用的是，有状态服务组件，就是StatefulSet组件。
1. 开发yaml文件内容如下：
# vim elasticsearch.yaml
apiVersion: apps/v1
kind: StatefulSet
metadata:name: es7-clusternamespace: sit
spec:serviceName: elasticsearchreplicas: 3selector:matchLabels:app: elasticsearchtemplate:metadata:labels:app: elasticsearchspec:containers:- name: elasticsearchimage: 192.20.67.250/public/elasticsearch:7.9.3resources:limits:cpu: 1000mrequests:cpu: 100mports:- containerPort: 9200name: restprotocol: TCP- containerPort: 9300name: inter-nodeprotocol: TCPvolumeMounts:- name: datamountPath: /usr/share/elasticsearch/dataenv:- name: cluster.namevalue: k8s-logs- name: node.namevalueFrom:fieldRef:fieldPath: metadata.name- name: discovery.zen.minimum_master_nodesvalue: "2"- name: discovery.seed_hostsvalue: "es7-cluster-0.elasticsearch,es7-cluster-1.elasticsearch,es7-cluster-2.elasticsearch"- name: cluster.initial_master_nodesvalue: "es7-cluster-0,es7-cluster-1,es7-cluster-2"- name: ES_JAVA_OPTSvalue: "-Xms1g -Xmx1g"initContainers:- name: fix-permissionsimage: 192.20.67.250/public/busybox:latestcommand: ["sh", "-c", "chown -R 1000:1000 /usr/share/elasticsearch/data"]securityContext:privileged: truevolumeMounts:- name: datamountPath: /usr/share/elasticsearch/data- name: increase-vm-max-mapimage: 192.20.67.250/public/busybox:latestcommand: ["sysctl", "-w", "vm.max_map_count=262144"]securityContext:privileged: true- name: increase-fd-ulimitimage: 192.20.67.250/public/busybox:latestcommand: ["sh", "-c", "ulimit -n 65536"]volumeClaimTemplates:- metadata:name: dataspec:accessModes: [ "ReadWriteOnce" ]storageClassName: "huawei-san"resources:requests:storage: 1Gi注：
1、这里使用pvc存储，因kubernetes集群有部署了storageclaas组件，所以这里是直接通过storageclass组件的方式创建pvc存储。
2、如果需要引起yaml文件里的内容，需要根据实际情况修改镜像地址和sc组件的名称。
这里还需要部署一个service组件，用于访问elasticsearch集群。
# vim elasticsearch-svc.yaml
apiVersion: v1
kind: Service
metadata:name: elasticsearchnamespace: sit
spec:selector:app: elasticsearchtype: ClusterIPports:- port: 9200name: es-9200targetPort: 9200- port: 9300name: es-9300targetPort: 93002. 创建elasticsearch集群：
执行生效yaml文件
# kubectl apply -f elasticsearch.yaml
statefulset.apps/elastic-cluster created
# kubectl apply -f elasticsearch-svc.yaml
service/elasticsearch-svc created
3. 查看运行情况：
查看sts组件运行情况：
# kubectl get sts
NAME READY AGE
es7-cluster 3/3 5m6s查看pod运行情况：
# kubectl get pods | grep es7
es7-cluster-0 1/1 Running 0 5m54s
es7-cluster-1 1/1 Running 0 4m23s
es7-cluster-2 1/1 Running 0 3m30s查看svc情况：
# kubectl get svc | grep ela
elasticsearch ClusterIP 172.32.151.215 <none> 9200/TCP,9300/TCP 22s
4. 访问elasticsearch服务：
3、开发elasticsearch集群，认证模式：
在kubernetes集群中部署elasticsearch集群，采用的是有状态服务组件，就是StatefulSet组件。
1. 开发yaml文件内容如下：
# vim elasticsearch.yaml

# kubectl apply -f elasticsearch-svc-p12.yaml

3. 查看运行情况：
查看sts组件运行情况：
# kubectl get sts

elastic-cluster 3/3 4m42s
查看pod运行情况：
# kubectl get pods | grep ela
elastic-cluster-0 1/1 Running 0 5m21s
elastic-cluster-1 1/1 Running 0 4m57s
elastic-cluster-2 1/1 Running 0 4m23s查看svc情况：
# kubectl get svc | grep ela
elastic-svc ClusterIP 172.45.199.17 <none> 9200/TCP,9300/TCP 5m46s
4.验证elasticsearch服务登入：
注：这里就提示需要密码登入了。
密码需要到 elastic-cluster-0容器中执行如下的命令：
注：这是自动生成密码
./bin/elasticsearch-setup-passwords auto
注：这里就能获取到密码了。
输入密码之后返回如下的内容：
注：到此kubernetes集群中部署elasticsearch集群的过程就结束了，希望可以帮助到大家。
