[K8S] Zabbix 搭建

什么？还没有搭建k8s，那赶紧看看 [K8S] 认证集群搭建 吧

容器这么火，我也玩玩，搭个zabbix测试下

 

1、首先上传 zabbix 相关镜像至 harbor

# docker login 192.168.1.206    #登录仓库

Username (admin):

Password:

Login Succeeded

 

#docker search zabbix      #搜索下载镜像

# docker pull zabbix/zabbix-web-nginx-mysql

# docker pull zabbix/zabbix-server-mysql

# docker pull zabbix/zabbix-proxy-mysql

# docker pull zabbix/zabbix-snmptraps

# docker pull mariadb

 

重复以下步骤打tag并上传

# docker tagzabbix-web-nginx-mysql192.168.1.206/mzh/zabbix-web-nginx-mysql  

# docker push 192.168.1.206/mzh/zabbix-web-nginx-mysql

 

 

2、编辑yaml文件

# vimariadb-server.yaml

apiVersion: extensions/v1beta1 kind: Deployment metadata:   name: mariadb-server spec:   replicas: 1   template:     metadata:       labels:         app: mariadb-server     spec:       containers:       - image: 192.168.1.206/mzh/mariadb         name: mariadb-server         ports:         - containerPort: 3306           name: db           protocol: TCP         env:         - name: MYSQL_ROOT_PASSWORD           value: "redhat"         volumeMounts:         - name: db-nfs           mountPath: /var/lib/mysql         #- name: conf         #  mountPath: /etc/mysql       volumes:       - name: db-nfs         nfs:           server: 192.168.1.206           path: "/bak/mariadb-server"      # - name: conf      #   nfs:      #     server: 192.168.1.206      #     path: "/data/zabbix/server/mysql-conf"

 

# vimariadb-server-svc.yaml

apiVersion: v1 kind: Service metadata:   name: mariadbserver   labels:     app: mariadbserver spec:   selector:     app: mariadb-server   ports:   - name: db     port: 3306     protocol: TCP

 

#kubectl create-f mariadb-server.yaml -f mariadb-server-svc.yaml  #先创建zabbixserver数据库

 

 

# vizabbix-server.yaml

apiVersion: extensions/v1beta1 kind: Deployment metadata:   name: zabbix-server spec:   replicas: 1   template:     metadata:       labels:         app: zabbix-server     spec:       containers:       - image: 192.168.1.206/mzh/zabbix-server-mysql         name: zabbix-server         ports:         - containerPort: 10051           name: server           protocol: TCP         env:         - name: DB_SERVER_HOST           value: "mariadbserver"         - name: MYSQL_USER           value: "zabbix"         - name: MYSQL_PASSWORD           value: "zabbix"         - name: MYSQL_DATABASE           value: "zabbix"         - name: ZBX_CACHESIZE           value: "2048M"         #volumeMounts:         #- name: snmptraps-nfs         #  mountPath: /var/lib/zabbix/snmptraps       #volumes:       #- name: snmptraps-nfs       #  nfs:       #    server: 192.168.1.206       #    path: "/data/zabbix/server/snmptraps"

 

# vizabbix-server-svc.yaml

apiVersion: v1 kind: Service metadata:   name: zabbixserver   labels:     app: zabbix-server spec:   clusterIP: 10.254.0.3   selector:     app: zabbix-server   ports:   - name: server     port: 10051     protocol: TCP

 

#kubectl create-f zabbix-server.yaml -f zabbix-server-svc.yaml    #再创建zabbix server pod

 

# vizabbix-web.yaml

apiVersion: extensions/v1beta1 kind: Deployment metadata:   name: zabbix-web spec:   replicas: 1   template:     metadata:       labels:         app: zabbix-web     spec:       containers:       - image: 192.168.1.206/mzh/zabbix-web-nginx-mysql         name: zabbix-web         ports:         - containerPort: 80           name: web           protocol: TCP         env:         - name: DB_SERVER_HOST           value: "mariadbserver"         - name: ZBX_SERVER_HOST           value: "zabbixserver"         - name: MYSQL_USER           value: "zabbix"         - name: MYSQL_PASSWORD           value: "zabbix"         - name: TZ           value: "Asia/Shanghai"

 

# vizabbix-web-svc.yaml

apiVersion: v1 kind: Service metadata:   name: zabbix-web   labels:     app: zabbix-web spec:   type: NodePort   selector:     app: zabbix-web   ports:   - name: web     port: 80     protocol: TCP

 

#kubectl create -f zabbix-web.yaml -f zabbix-web-svc.yaml    #创建 zabbix -web pod

# kubectl get svc

zabbix-web      10.254.165.249   <nodes>       80:10158/TCP   26d

 

#通过浏览器访问http://192.168.1.207:10158 就可以访问zabbix了

 

#下面是设置 proxy代理

# vimariadb-proxy.yaml

apiVersion: extensions/v1beta1 kind: Deployment metadata:   name: mariadb-proxy spec:   replicas: 1   template:     metadata:       labels:         app: mariadb-proxy     spec:       containers:       - image: 192.168.1.206/mzh/mariadb         name: mariadb-proxy         ports:         - containerPort: 3306           name: db           protocol: TCP         env:         - name: MYSQL_ROOT_PASSWORD           value: "redhat"         volumeMounts:         - name: db-nfs           mountPath: /var/lib/mysql         #- name: conf         #  mountPath: /etc/mysql       volumes:       - name: db-nfs         nfs:           server: 192.168.1.206           path: "/bak/mariadb-proxy"      # - name: conf      #   nfs:      #     server: 192.168.1.206      #     path: "/data/zabbix/server/mysql-conf"

 

# vimariadb-proxy-svc.yaml

apiVersion: v1 kind: Service metadata:   name: mariadbproxy   labels:     app: mariadbproxy spec:   clusterIP: 10.254.0.4   selector:     app: mariadb-proxy   ports:   - name: db     port: 3306     protocol: TCP

 

#kubectl create -f mariadb-proxy.yaml -f mariadb-proxy-svc.yaml   #创建proxy数据库

 

#这里我本来是用 zabbix-proxy-mysql镜像来搭建proxy代理容器的，但是发现全部搭建完后，无法用来监控agent和获取数据，proxy容器内部无法访问外部？。

所以，如果你有足够的耐心看到这里，就会发现，我之前的yaml文件中有zabbixserver和mariadbproxy是给的固定CLUSTER-IP，分别为10.254.0.3  和10.254.0.4。

所以我决定将 proxy安装在 k8s集群任意物理节点上，在zabbix-proxy配置文件中用刚才的两个ip配置就OK了。

过程略，关于zabbix配置什么的参考【Zabbix】项  相关文档吧。
