一、zabbix介绍

1.zabbix简介

Zabbix是一个基于Web界面的分布式系统监控的企业级开源软件。可以监视各种系统与设备的参数，保障服务器及设备的安全运营。

2.zabbix特点

（1）安装与配置简单。
（2）可视化web管理界面。
（3）免费开源。
（4）支持中文。
（5）自动发现。
（6）分布式监控。
（7）实时绘图。

3.zabbix的主要功能

1.硬件监控。如交换机、路由器、打印机等。
2.系统监控。如CPU,内存，磁盘。硬盘IO，系统负载等。
3.服务监控。如apache,nginx,tomcat,redis,TCP连接数等。
4.性能监控。如网站性能，服务器性能，数据库性能。
5.日志监控。如访问日志，错误日志。
6.安全监控。如用户登录数，本地文件改动，passwd文件变化。
7.网络监控。如端口，SMTP,网络使用率，网络入流量，网络出流量。

二、检查本地k8s环境

1.检查系统pod运行状态

[root@k8s-master ~]# kubectl get pods -ANAMESPACE     NAME       READY   STATUS    RESTARTSAGEkube-system   calico-kube-controllers-7bc6547ffb-2nf66   1/1     Running   1 (9m28s ago)   2d16hkube-system   calico-node-8c4pn  1/1     Running   1 (9m16s ago)   2d16hkube-system   calico-node-f28qq  1/1     Running   1 (9m10s ago)   2d16hkube-system   calico-node-wmc2j  1/1     Running   1 (9m29s ago)   2d16hkube-system   coredns-6d8c4cb4d-6gm4x    1/1     Running   1 (9m28s ago)   2d16hkube-system   coredns-6d8c4cb4d-7vxlz    1/1     Running   1 (9m29s ago)   2d16hkube-system   etcd-k8s-master    1/1     Running   1 (9m30s ago)   2d16hkube-system   kube-apiserver-k8s-master  1/1     Running   1 (9m29s ago)   2d16hkube-system   kube-controller-manager-k8s-master 1/1     Running   1 (9m30s ago)   2d16hkube-system   kube-proxy-8dfw8   1/1     Running   1 (9m29s ago)   2d16hkube-system   kube-proxy-ghzrv   1/1     Running   1 (9m9s ago)    2d16hkube-system   kube-proxy-j867z   1/1     Running   1 (9m15s ago)   2d16hkube-system   kube-scheduler-k8s-master  1/1     Running   1 (9m28s ago)   2d16h

2.检查node节点状态

[root@k8s-master ~]# kubectl get nodes -owideNAME STATUS   ROLES  AGE     VERSION   INTERNAL-IP     EXTERNAL-IP   OS-IMAGEKERNEL-VERSION  CONTAINER-RUNTIMEk8s-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://1.6.6k8s-node01   Ready    <none> 2d16h   v1.23.1   192.168.3.202   <none>CentOS Linux 7 (Core)   3.10.0-957.el7.x86_64   containerd://1.6.6k8s-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、配置nfs共享存储

1.安装nfs

 yum install -y nfs-utils

2.创建共享目录

mkdir -p /nfs/data

3.配置共享目录

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

4.启动相关服务

systemctl enable rpcbindsystemctl enable nfs-serversystemctl start rpcbind

5.使配置生效

exportfs -r

6.查看nfs

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

7.其他节点检查nfs共享

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

四、安装zabbix-mysql

1.编写zabbix-mysql的yaml文件

[root@k8s-master zabbix]# cat zabbix_mysql.yaml ---apiVersion: v1kind: PersistentVolumemetadata:  name: zabbixdb-pvspec:  capacity:   #创建存储的大小    storage: 10Gi  volumeMode: Filesystem  #存储的类型  accessModes:    - ReadWriteOnce  persistentVolumeReclaimPolicy: Recycle  nfs:    path: /nfs/data/zabbix    server: 192.168.3.201  mountOptions:    - hard    - nfsvers=4.1---apiVersion: v1kind: PersistentVolumeClaimmetadata:  name: zabbixdb-pvc  namespace: zabbixspec:  accessModes:    - ReadWriteOnce  volumeMode: Filesystem   #存储类型 ，块存储Block  resources:    requests:      storage: 8Gi---apiVersion: apps/v1kind: Deploymentmetadata:  labels:    app: zabbixdb  name: zabbixdb  namespace: zabbixspec:  replicas: 1  selector:    matchLabels:      app: zabbixdb  strategy: {}  template:    metadata:      labels:app: zabbixdb    spec:      volumes:      - name: zabbixdb-datapersistentVolumeClaim:  claimName: zabbixdb-pvc      containers:      - image: mysql:8.0name: mysqlports:- name: mysql  containerPort: 3306  protocol: TCPvolumeMounts:- name: zabbixdb-data  mountPath: /var/lib/mysqlenv:- name: MYSQL_DATABASE  value: "zabbix"- name: MYSQL_USER  value: "zabbix"- name: MYSQL_PASSWORD  value: "zabbix"- name: MYSQL_ROOT_PASSWORD  value: "zabbix"resources:   requests:     cpu: 0.1     memory: 128Mi  limits:     cpu: 0.3     memory:  512Mi---  apiVersion: v1kind: Servicemetadata:  creationTimestamp: null  labels:    app: zabbixdb  name: zabbixdb  namespace: zabbixspec:  clusterIP: 10.96.1.99  ports:  - name: 3306-3306    port: 3306    protocol: TCP    targetPort: 3306  selector:    app: zabbixdb  type: ClusterIPstatus:  loadBalancer: {}

2.创建命名空间

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

3.创建zabbix数据库

kubectl apply -f zabbix_mysql.yaml

4.检查pod状态

[root@k8s-master zabbix]# kubectl get pods -n zabbix NAMEREADY   STATUS    RESTARTS   AGEzabbixdb-69b7cd8dff-jnpjd   1/1     Running   0  11m

五、检查zabbix数据库的service域名

1.运行测试pod

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

2.进入busybox的pod

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

3.查看域名解析

[root@k8s-master ~]# kubectl exec -it busybox -- /bin/sh/ # nslookup zabbixdb.zabbix.svc.cluster.localServer:    10.96.0.10Address 1: 10.96.0.10 kube-dns.kube-system.svc.cluster.localName:      zabbixdb.zabbix.svc.cluster.localAddress 1: 10.96.1.99 zabbixdb.zabbix.svc.cluster.local/ #

六、安装zabbix-server

1.编写zabbix_server.yaml文件

[root@k8s-master zabbix]# cat zabbix_server.yaml apiVersion: apps/v1kind: Deploymentmetadata:  creationTimestamp: null  labels:    app: zabbix-server  name: zabbix-server  namespace: zabbixspec:  replicas: 1  selector:    matchLabels:      app: zabbix-server  strategy: {}  template:    metadata:      creationTimestamp: null      labels:app: zabbix-server    spec:      volumes:      - name: zabbix-scriptshostPath:  path: /usr/lib/zabbix/      - name: zabbix-filehostPath:  path: /var/lib/zabbix       nodeSelector:zabbix-server: "true"      hostNetwork: true      containers:      - image: zabbix/zabbix-server-mysql:6.0-ubuntu-latestname: zabbix-server-mysqlenv:- name: DB_SERVER_HOST  value:  10.96.1.99- name: MYSQL_USER  value: zabbix- name: MYSQL_PASSWORD  value: zabbixresources: {}status: {}

2.给node02节点打上标签

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

3.安装zabbix-server

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

4.检查pod状态

[root@k8s-master zabbix]# kubectl get pods -n zabbixNAME     READY   STATUS    RESTARTS   AGEzabbix-server-5f48d9d57d-rkr5p   1/1     Running   0  66szabbixdb-69b7cd8dff-krt2w1/1     Running   0  4m22s

七、部署zabbix-web

1.编写zabbix_web.yaml文件

[root@k8s-master zabbix]# cat zabbix_web.yaml apiVersion: apps/v1kind: Deploymentmetadata:  creationTimestamp: null  labels:    app: zabbix-web  name: zabbix-web  namespace: zabbixspec:  replicas: 1  selector:    matchLabels:      app: zabbix-web  strategy: {}  template:    metadata:      creationTimestamp: null      labels:app: zabbix-web    spec:      containers:      - image: zabbix/zabbix-web-nginx-mysql:6.0-ubuntu-latestname: zabbix-web-nginx-mysqlenv:- name: DB_SERVER_HOST  value: zabbixdb.zabbix.svc.cluster.local- name: MYSQL_USER  value: zabbix- name: MYSQL_PASSWORD  value: zabbix- name: ZBX_SERVER_HOST  value: 192.168.3.201- name: PHP_TZ  value: Asia/shanghairesources: {}status: {}---apiVersion: v1kind: Servicemetadata:  creationTimestamp: null  labels:    app: zabbix-web  name: zabbix-web  namespace: zabbixspec:  ports:  - name: 8080-8080    port: 8080    protocol: TCP    targetPort: 8080  selector:    app: zabbix-web  type: NodePortstatus:  loadBalancer: {}

2.安装zabbix-web

[root@k8s-master zabbix]# kubectl apply -f zabbix_web.yaml deployment.apps/zabbix-web createdservice/zabbix-web created

3.查看pod状态

[root@k8s-master zabbix]# kubectl get pods -n zabbixNAME     READY   STATUS    RESTARTS   AGEzabbix-server-5f48d9d57d-rkr5p   1/1     Running   0  2m36szabbix-web-55cd66f74f-9f284      1/1     Running   0  18szabbixdb-69b7cd8dff-krt2w1/1     Running   0  5m52s

八、部署zabbix-agent

1.编辑zabbix_agent.yaml

[root@k8s-master zabbix]# cat zabbix_agent.yaml apiVersion: apps/v1kind: DaemonSetmetadata:  labels:    app: zabbix-agent  name: zabbix-agent  namespace: zabbixspec:  selector:    matchLabels:      app: zabbix-agent  template:    metadata:      creationTimestamp: null      labels:app: zabbix-agent    spec:      hostNetwork: true      containers:      - image: zabbix/zabbix-agent:6.0-ubuntu-latestname: zabbix-agentenv:- name: ZBX_SERVER_HOST  value: 192.168.3.201resources: {}

2.安装zabbix-agent

 kubectl apply -f zabbix_agent.yaml

3.查看pod状态

九、访问zabbix的web

1.查看svc

[root@k8s-master zabbix]#  kubectl get svc -n zabbix NAME TYPECLUSTER-IP    EXTERNAL-IP   PORT(S)  AGEzabbix-web   NodePort    10.100.50.7   <none>8080:30775/TCP   59szabbixdb     ClusterIP   10.96.1.99    <none>3306/TCP 6m33s

2.登录web

http://192.168.3.202:30775

3.登录zabbix

初始账号admin/zabbix

4.查询zabbix-server的监控项图表
