kubernetes集群搭建Zabbix监控平台的详细过程
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 -A NAMESPACE NAME READY STATUS RESTARTS AGE kube-system calico-kube-controllers-7bc6547ffb-2nf66 1/1 Running 1 (9m28s ago) 2d16h kube-system calico-node-8c4pn 1/1 Running 1 (9m16s ago) 2d16h kube-system calico-node-f28qq 1/1 Running 1 (9m10s ago) 2d16h kube-system calico-node-wmc2j 1/1 Running 1 (9m29s ago) 2d16h kube-system coredns-6d8c4cb4d-6gm4x 1/1 Running 1 (9m28s ago) 2d16h kube-system coredns-6d8c4cb4d-7vxlz 1/1 Running 1 (9m29s ago) 2d16h 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.检查node节点状态
[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、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 rpcbind systemctl enable nfs-server systemctl 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 192.168.3.201 Export 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: v1 kind: PersistentVolume metadata: name: zabbixdb-pv spec: 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: v1 kind: PersistentVolumeClaim metadata: name: zabbixdb-pvc namespace: zabbix spec: accessModes: - ReadWriteOnce volumeMode: Filesystem #存储类型 ,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 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: v1 kind: Service metadata: creationTimestamp: null labels: app: zabbixdb name: zabbixdb namespace: zabbix spec: clusterIP: 10.96.1.99 ports: - name: 3306-3306 port: 3306 protocol: TCP targetPort: 3306 selector: app: zabbixdb type: ClusterIP status: loadBalancer: {}
2.创建命名空间
[root@k8s-master zabbix]# kubectl create namespace zabbix namespace/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 NAME READY STATUS RESTARTS AGE zabbixdb-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 3600 pod/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.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、安装zabbix-server
1.编写zabbix_server.yaml文件
[root@k8s-master zabbix]# cat zabbix_server.yaml apiVersion: apps/v1 kind: Deployment metadata: creationTimestamp: null labels: 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.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 zabbix NAME READY STATUS RESTARTS AGE zabbix-server-5f48d9d57d-rkr5p 1/1 Running 0 66s zabbixdb-69b7cd8dff-krt2w 1/1 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/v1 kind: Deployment metadata: creationTimestamp: null labels: app: zabbix-web name: zabbix-web namespace: zabbix spec: 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-latest name: zabbix-web-nginx-mysql env: - 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/shanghai resources: {} status: {} --- apiVersion: v1 kind: Service metadata: creationTimestamp: null labels: app: zabbix-web name: zabbix-web namespace: zabbix spec: ports: - name: 8080-8080 port: 8080 protocol: TCP targetPort: 8080 selector: app: zabbix-web type: NodePort status: loadBalancer: {}
