一、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 CentOS Linux 7 (Core) 3.10.0-957.el7.x86_64 containerd://1.6.6 k8s-node01 Ready 2d16h v1.23.1 192.168.3.202 CentOS Linux 7 (Core) 3.10.0-957.el7.x86_64 containerd://1.6.6 k8s-node02 Ready 2d16h v1.23.1 192.168.3.203 CentOS Linux 7 (Core) 3.10.0-957.el7.x86_64 containerd://1.6.6

二、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

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 *

三、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

四、检查zabbix数据库的service域名
