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

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
