k8s部署zabbix_k8s部署zabbix监控系统
zabbix简介
Zabbix 是一种网络监视、管理系统，基于 Server-Client 架构。可用于监视各种网络服务、服务器和网络机器等状态。Zabbix 使用 MySQL、PostgreSQL、SQLite、Oracle 或 IBM DB2 储存资料。Server 端基于 C语言、Web 前端则是基于 PHP 所制作的。Zabbix 可以使用多种方式监视。可以只使用 Simple Check 不需要安装 Client 端，亦可基于 SMTP 或 HTTP 等各种协定做死活监视。在客户端如 UNIX、Windows 中安装 Zabbix Agent 之后，可监视 CPU 负荷、网络使用状况、硬盘容量等各种状态。而就算没有安装 Agent 在监视对象中，Zabbix 也可以经由 SNMP、TCP、ICMP检查，以及利用 IPMI、SSH、telnet 对目标进行监视。另外，Zabbix 包含 XMPP 等各种 Item 警示功能。

zabbix k8s部署部署mysql(采用hostpath做数据持久化)
1.创建pvvim mysql-pv.yamlkind: PersistentVolume
apiVersion: v1
metadata:
name: mysql-pv-volume
labels:
type: local
spec:
storageClassName: manual
capacity:
storage: 20Gi
accessModes:
- ReadWriteOnce
hostPath:
path: "/mnt/data"
---
apiVersion: v1
kind: PersistentVolumeClaim
metadata:
name: mysql-pv-claim
spec:
storageClassName: manual
accessModes:
- ReadWriteOnce
resources:
requests:
storage: 20Gi
2.创建mysql配置文件(configMap)vim mysql-config.yamlapiVersion: v1
kind: ConfigMap
metadata:
name: mysql-config
data:
custom.cnf: |
[mysqld]
default_storage_engine=innodb
skip_external_locking
skip_host_cache
skip_name_resolve
default_authentication_plugin=mysql_native_password
3.创建mysql密码(secret)[root@k8s-master-01 mysql]# echo -n password|base64
cGFzc3dvcmQ=
vim mysql-secret.yamlapiVersion: v1
kind: Secret
metadata:
name: mysql-user-pwd
data:
mysql-root-pwd: cGFzc3dvcmQ=
4.创建mysql部署文件vim mysql-deploy.yamlapiVersion: v1

metadata:
name: mysql
spec:
type: NodePort
ports:
- port: 3306
nodePort: 30006

5.使用kubectl命令及以上yaml文件部署mysql[root@k8s-master-01 mysql]# kubectl apply -f ./
