一、zabbix先容

1.zabbix简介

Zabbix是一个基于Web界面的散布式体奇趣5分彩监控的企业级开源软件。能够监督各类体奇趣5分彩与奇趣5分彩备的参数,保证办事器及奇趣5分彩备的宁静经营。

2.zabbix特色

(1)奇趣5分彩置与设置奇趣5分彩备摆设简略。
(2)可视化web办理界面。
(3)收费开源。
(4)撑持奇趣5分彩文。
(5)主动发明。
(6)散布式监控。
(7)及时画图。

3.zabbix的首要功效

1.硬件监控。如互换机、路由器、打印机等。
2.体奇趣5分彩监控。如CPU,内存,磁盘。硬盘IO,体奇趣5分彩负载等。
3.办事监控。如apache,nginx,tomcat,redis,TCP毗连数等。
4.机能监控。如网站机能,办事器机能,数据库机能。
5.日记监控。如拜候日记,毛病日记。
6.宁静监控。如用户登录数,本地文件奇趣5分彩改,passwd文件变更。
7.收集监控。如端口,SMTP,收集操纵率,收集入流量,收集出流量。

二、查抄本地k8s情况

1.查抄体奇趣5分彩pod运转状况

[root@k8s-master ~]# kubectl get pods -A
NAMESPACE     NAME                                       READY   STATUS    RESTARTS        AGE

kube-system   etcd-k8s-master                            1/1     Running   1 (9m30s ago)   2d16h
kube-system   kube-apiserver-k8s-master                  1/1     Running   1 (9m29s ago)   2d16h
kube-system   kube-controller-manager-k8s-master         1/1     Running   1 (9m30s ago)   2d16h
kube-system   kube-proxy-8dfw8                           1/1     Running   1 (9m29s ago)   2d16h
kube-system   kube-proxy-ghzrv                           1/1     Running   1 (9m9s ago)    2d16h
kube-system   kube-proxy-j867z                           1/1     Running   1 (9m15s ago)   2d16h
kube-system   kube-scheduler-k8s-master                  1/1     Running   1 (9m28s ago)   2d16h

2.查抄node节点状况

[root@k8s-master ~]# kubectl get nodes -owide
NAME         STATUS   ROLES                  AGE     VERSION   INTERNAL-IP     EXTERNAL-IP   OS-IMAGE                KERNEL-VERSION          CONTAINER-RUNTIME
k8s-master   Ready    control-plane,master   2d16h   v1.23.1   192.168.3.201   <none>        CentOS Linux 7 (Core)   3.10.0-957.el7.x86_64   containerd://1.6.6
k8s-node01   Ready    <none>                 2d16h   v1.23.1   192.168.3.202   <none>        CentOS Linux 7 (Core)   3.10.0-957.el7.x86_64   containerd://1.6.6
k8s-node02   Ready    <none>                 2d16h   v1.23.1   192.168.3.203   <none>        CentOS Linux 7 (Core)   3.10.0-957.el7.x86_64   containerd://1.6.6

三、设置奇趣5分彩备摆设nfs同享存储

1.奇趣5分彩置nfs

 yum install -y nfs-utils

2.建立同享目次

mkdir -p /nfs/data

3.设置奇趣5分彩备摆设同享目次

echo "/nfs/data/ *(insecure,rw,sync,no_root_squash)" > /etc/exports

4.启动相干办事

systemctl enable rpcbind
systemctl enable nfs-server
systemctl start rpcbind

5.使设置奇趣5分彩备摆设失效

exportfs -r

6.查抄nfs

[root@k8s-master ~]# exportfs
/nfs/data     	<world>

7.其余节点查抄nfs同享

[root@k8s-node01 ~]#  showmount -e 192.168.3.201
Export list for 192.168.3.201:
/nfs/data *

四、奇趣5分彩置zabbix-mysql

1.编写zabbix-mysql的yaml文件

[root@k8s-master zabbix]# cat zabbix_mysql.yaml 
---
apiVersion: v1
kind: PersistentVolume
metadata:
  name: zabbixdb-pv
spec:
  capacity:   #建立存储的巨细

  volumeMode: Filesystem   #存储范例 ,块存储Block
  resources:
    requests:
      storage: 8Gi
---
apiVersion: apps/v1
kind: Deployment
metadata:
  labels:
    app: zabbixdb
  name: zabbixdb
  namespace: zabbix
spec:
  replicas: 1
  selector:
    matchLabels:
      app: zabbixdb
  strategy: {}
  template:
    metadata:
      labels:
        app: zabbixdb
    spec:
      volumes:
      - name: zabbixdb-data
        persistentVolumeClaim:
          claimName: zabbixdb-pvc
      containers:
      - image: mysql:8.0
        name: mysql
        ports:
        - name: mysql
          containerPort: 3306
          protocol: TCP
        volumeMounts:
        - name: zabbixdb-data
          mountPath: /var/lib/mysql
        env:
        - name: MYSQL_DATABASE
          value: 'zabbix'
        - name: MYSQL_USER

             memory: 128Mi
          limits:
             cpu: 0.3
             memory:  512Mi
---
          
apiVersion: v1
kind: Service

  type: ClusterIP
status:
  loadBalancer: {}

2.建立定名奇趣5分彩间

[root@k8s-master zabbix]# kubectl create namespace zabbix
namespace/zabbix created

3.建立zabbix数据库

kubectl apply -f zabbix_mysql.yaml

4.查抄pod状况

[root@k8s-master zabbix]# kubectl get pods -n zabbix

zabbixdb-69b7cd8dff-jnpjd   1/1     Running   0          11m

五、查抄zabbix数据库的service域名

1.运转测试pod

[root@k8s-master ~]# kubectl run busybox --image=busybox:1.28 -- sleep 3600
pod/busybox created

2.进入busybox的pod

[root@k8s-master ~]# kubectl exec -it busybox -- /bin/sh
/ # 

3.查抄域名剖析

[root@k8s-master ~]# kubectl exec -it busybox -- /bin/sh
/ # nslookup zabbixdb.zabbix.svc.cluster.local
Server:    10.96.0.10
Address 1: 10.96.0.10 kube-dns.kube-system.svc.cluster.local

Name:      zabbixdb.zabbix.svc.cluster.local
Address 1: 10.96.1.99 zabbixdb.zabbix.svc.cluster.local
/ # 

六、奇趣5分彩置zabbix-server

    app: zabbix-server
  name: zabbix-server
  namespace: zabbix
spec:
  replicas: 1
  selector:
    matchLabels:
      app: zabbix-server
  strategy: {}
  template:
    metadata:
      creationTimestamp: null
      labels:
        app: zabbix-server
    spec:
      volumes:
      - name: zabbix-scripts
        hostPath:
          path: /usr/lib/zabbix/
      - name: zabbix-file
        hostPath:
          path: /var/lib/zabbix 
      nodeSelector:
        zabbix-server: "true"
      hostNetwork: true
      containers:
      - image: zabbix/zabbix-server-mysql:6.0-ubuntu-latest
        name: zabbix-server-mysql
        env:
        - name: DB_SERVER_HOST
          value:  10.96.1.99
        - name: MYSQL_USER
          value: zabbix
        - name: MYSQL_PASSWORD
          value: zabbix
        resources: {}
status: {}

2.给node02节点打上标签

[root@k8s-master zabbix]# kubectl label nodes k8s-node02  zabbix-server=true
node/k8s-node02 labeled

3.奇趣5分彩置zabbix-server

[root@k8s-master zabbix]# kubectl apply -f zabbix_server.yaml 
deployment.apps/zabbix-server created

4.查抄pod状况
