瀏覽：422日期：2023-04-06 15:09:23

一、zabbix介紹

1.zabbix簡介

Zabbix是一個基于Web界面的分布式系統(tǒng)監(jiān)控的企業(yè)級開源軟件。可以監(jiān)視各種系統(tǒng)與設(shè)備的參數(shù)，保障服務(wù)器及設(shè)備的安全運營。

2.zabbix特點

（1）安裝與配置簡單。
（2）可視化web管理界面。
（3）免費開源。
（4）支持中文。
（5）自動發(fā)現(xiàn)。
（6）分布式監(jiān)控。
（7）實時繪圖。

3.zabbix的主要功能

1.硬件監(jiān)控。如交換機、路由器、打印機等。
2.系統(tǒng)監(jiān)控。如CPU,內(nèi)存，磁盤。硬盤IO，系統(tǒng)負載等。
3.服務(wù)監(jiān)控。如apache,nginx,tomcat,redis,TCP連接數(shù)等。
4.性能監(jiān)控。如網(wǎng)站性能，服務(wù)器性能，數(shù)據(jù)庫性能。
5.日志監(jiān)控。如訪問日志，錯誤日志。
6.安全監(jiān)控。如用戶登錄數(shù)，本地文件改動，passwd文件變化。
7.網(wǎng)絡(luò)監(jiān)控。如端口，SMTP,網(wǎng)絡(luò)使用率，網(wǎng)絡(luò)入流量，網(wǎng)絡(luò)出流量。

二、檢查本地k8s環(huán)境

1.檢查系統(tǒng)pod運行狀態(tài)

[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.檢查node節(jié)點狀態(tài)

[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共享存儲

1.安裝nfs

 yum install -y nfs-utils

2.創(chuàng)建共享目錄

mkdir -p /nfs/data

3.配置共享目錄

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

4.啟動相關(guān)服務(wù)

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.其他節(jié)點檢查nfs共享

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

四、安裝zabbix-mysql

1.編寫zabbix-mysql的yaml文件

[root@k8s-master zabbix]# cat zabbix_mysql.yaml ---apiVersion: v1kind: PersistentVolumemetadata:  name: zabbixdb-pvspec:  capacity:   #創(chuàng)建存儲的大小    storage: 10Gi  volumeMode: Filesystem  #存儲的類型  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   #存儲類型 ，塊存儲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.創(chuàng)建命名空間

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

3.創(chuàng)建zabbix數(shù)據(jù)庫

kubectl apply -f zabbix_mysql.yaml

4.檢查pod狀態(tài)

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

五、檢查zabbix數(shù)據(jù)庫的service域名

1.運行測試pod

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

2.進入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、安裝zabbix-server

1.編寫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.給node02節(jié)點打上標簽
