基于k8s集群部署安装Zabbix

一、搭建k8s集群

1、检查环境

1.1配置静态IP

示例（最小化配置必须的参数）

[root@k8s-master01 ~]# vi etc/sysconfig/network-scripts/ifcfg-ens192

BOOTPROTO="none"

NAME="ens192"

DEVICE="ens192"

ONBOOT="yes"

IPADDR=192.168.3.174

PREFIX=24

GATEWAY=192.168.1.1

DNS1=114.114.114.114

[root@k8s-master01 ~]# systemctl restart network #刷新网络服务

[root@k8s-master01 ~]# ip a #查看ip

1.2 配置添加hosts

[root@k8s-master01 ~]# cat /etc/hosts

127.0.0.1 localhost localhost.localdomain localhost4 localhost4.localdomain4

::1 localhost localhost.localdomain localhost6 localhost6.localdomain6

192.168.3.174 k8s-master01

192.168.3.175 k8s-node01

192.168.3.176 k8s-node02

[root@k8s-master01 ~]#

2、配置docker环境

(1)清理现有 Docker 并配置源

# 卸载可能存在的旧版本 Docker

sudo yum remove docker docker-engine docker-ce docker-* containerd.io

# 添加阿里云 CentOS 8 基础源

sudo curl -o /etc/yum.repos.d/CentOS-Base.repo https://mirrors.aliyun.com/repo/Centos-8.repo

# 添加 Docker CE 源（阿里云镜像）

sudo yum-config-manager --add-repo https://mirrors.aliyun.com/docker-ce/linux/centos/docker-ce.repo

# 修正 yum 变量（关键步骤！强制使用 centos 8 的包）

echo "8" | sudo tee /etc/yum/vars/centos_version > /dev/null

sudo sed -i 's/$releasever/$centos_version/g' /etc/yum.repos.d/docker-ce.repo

sudo sed -i 's/$releasever/$centos_version/g' /etc/yum.repos.d/CentOS-Base.repo

# 更新缓存

sudo yum makecache

# 查看所有可用的 Docker CE 版本

yum list docker-ce --showduplicates | sort -r

#让包管理器自动解决依赖关系。注意，这会安装软件源中标记为默认或最新的版本

yum install -y docker-ce docker-ce-cli containerd.io

或# 选择一个较新但非最新的版本进行安装（例如 26.1.3）

yum install -y docker-ce-26.1.3-1.el8 docker-ce-cli-26.1.3-1.el8 containerd.io

(2)配置docker的国内源

# 创建/etc/docker目录（如果不存在）

sudo mkdir -p /etc/docker

# 配置Docker守护进程，尤其是cgroup驱动

cat <<EOF | sudo tee /etc/docker/daemon.json

{

"registry-mirrors": ["https://hub.docker-alhk.dkdun.com/"],

"exec-opts": ["native.cgroupdriver=systemd"]

}

EOF

# 重启Docker以应用配置

sudo systemctl daemon-reload

sudo systemctl restart docker

# 设置Docker开机自启

sudo systemctl enable docker.service

sudo systemctl status dokcer

3、配置k8s组件源

（1）配置国内yum源

cat <<EOF | tee /etc/yum.repos.d/kubernetes.repo

[kubernetes]

name=Kubernetes

baseurl=https://mirrors.aliyun.com/kubernetes/yum/repos/kubernetes-el7-x86_64

enabled=1

gpgcheck=0

repo_gpgcheck=0

gpgkey=https://mirrors.aliyun.com/kubernetes/yum/doc/yum-key.gpg https://mirrors.aliyun.com/kubernetes/yum/doc/rpm-package-key.gpg

EOF

# 更新索引缓冲

yum makecache

（2）安装kubelet、kubeadm和kubectl

# 安装指定版本，建议指定版本以避免兼容性问题

yum install -y kubeadm-1.23.17-0 kubelet-1.23.17-0 kubectl-1.23.17-0 --disableexcludes=kubernetes

# 或者安装当前最新稳定版

# sudo yum install -y kubelet kubeadm kubectl

# 启用kubelet服务，但暂不启动（需初始化后才会正常）

sudo systemctl enable kubelet

4、集群初始化

（1）初始化Kubernetes控制平面（Master节点）以下步骤仅在Master节点上执行：

kubeadm init \

--apiserver-advertise-address=192.168.3.174 \ # 替换为你的Master节点IP

--image-repository registry.aliyuncs.com/google_containers \ # 使用国内镜像源

--kubernetes-version=v1.23.17 \ # 指定与安装一致的版本

--service-cidr=10.96.0.0/12 \ #指定 Service 网络的 IP 地址范围。

--pod-network-cidr=10.244.0.0/16 # 设置Pod网络CIDR，需与后续CNI插件匹配

成功后会提示一下信息

继续执行

mkdir -p $HOME/.kube

sudo cp -i /etc/kubernetes/admin.conf $HOME/.kube/config

sudo chown $(id -u):$(id -g) $HOME/.kube/config

在node节点执行加入到集群

kubeadm join 192.168.3.174:6443 --token g5aqri.02haydobvjfu7dnl \

--discovery-token-ca-cert-hash sha256:95fd4a7fd82ccde7b329ea551130340a837a3aa612145caa2435d2c18b3c91ef

查看集群

[root@k8s-master01 ~]# kubectl label node k8s-node01 node-role.kubernetes.io/worker=worker

node/k8s-node01 labeled

[root@k8s-master01 ~]# kubectl label node k8s-node02 node-role.kubernetes.io/worker=worker

node/k8s-node02 labeled

[root@k8s-master01 ~]# kubectl get nodes

NAME STATUS ROLES AGE VERSION

k8s-master01 NotReady control-plane,master 4h29m v1.23.17

k8s-node01 NotReady worker 3m45s v1.23.17

k8s-node02 NotReady worker 41m v1.23.17

[root@k8s-master01 ~]#

#过一段时间

[root@k8s-master01 ~]# kubectl get nodes

NAME STATUS ROLES AGE VERSION

k8s-master01 Ready control-plane,master 24m v1.23.17

k8s-node01 Ready worker 18m v1.23.17

k8s-node02 Ready worker 18m v1.23.17

二、部署zabbix

如果镜像拉取有问题，可先手动导入(连接下载解压：通过网盘分享的文件：zabbix-all.zip链接: https://pan.baidu.com/s/1VsVlPF8RAZUlP3F2b5IxYQ?pwd=5h2u提取码: 5h2u)

# 导入 Zabbix Server

docker load -i zabbix-server-mysql.tar.gz

# 导入 Zabbix Web

docker load -i zabbix-web-nginx-mysql.tar.gz

# 导入 Zabbix Agent

docker load -i zabbix-agent.tar.gz

#导入数据库

docker load -i mysql:8.0.gz

1、安装zabbix的数据库（MySQL或PostgreSQL）

（1）本次测试选择MySQL，创建mysql-deploy.yaml文件

apiVersion: v1

kind: PersistentVolumeClaim

metadata:

namespace: zabbix

spec:

accessModes:

- ReadWriteOnce

resources:

requests:

storage: 10Gi #根据需求调整存储大小

#若有StorageClass，取消注释并指定（如：storageClassName: "standard"）

# storageClassName: "your-storage-class"

---

apiVersion: apps/v1

kind: Deployment

metadata:

namespace: zabbix

spec:

replicas: 1

selector:

matchLabels:

app: mysql

template:

metadata:

labels:

app: mysql

spec:

containers:

- name: mysql

image: mysql:8.0 #官方MySQL镜像

imagePullPolicy: IfNotPresent

ports:

- containerPort: 3306

env:

- name: MYSQL_ROOT_PASSWORD

value: "Root@123" # root密码，建议修改

- name: MYSQL_DATABASE

value: "zabbix" # Zabbix数据库名

- name: MYSQL_USER

value: "zabbix" # Zabbix数据库用户

- name: MYSQL_PASSWORD

value: "zabbix" # Zabbix用户密码，建议修改

volumeMounts:

- name: mysql-data

mountPath: /var/lib/mysql # MySQL数据目录

resources:

requests:

cpu: 300m

memory: 300Mi

limits:

persistentVolumeClaim:

claimName: mysql-pvc

---

apiVersion: v1

kind: Service

metadata:

namespace: zabbix

spec:

selector:

app: mysql

ports:

- port: 3306

targetPort: 3306

type: ClusterIP #仅集群内部访问

（2）应用部署

kubectl apply -f mysql-deploy.yaml

（3）验证 MySQL 是否运行

kubectl get pods -n zabbix -l app=mysql

# 状态应为Running

示例：

[root@k8s-master01 ~]# kubectl get pods -n zabbix -l app=mysql

NAME READY STATUS RESTARTS AGE

mysql-758b6cf559-7d2kh 1/1 Running 0 40m

[root@k8s-master01 ~]#

2、部署zabbix server

（1）Zabbix Server 是核心组件，负责处理监控数据。需连接 MySQL，创建zabbix-server-deploy.yaml

[root@k8s-master01 ~]# cat zabbix-server-deploy.yaml

apiVersion: apps/v1

kind: Deployment

metadata:

namespace: zabbix

spec:

replicas: 1

selector:

matchLabels:

app: zabbix-server

template:

metadata:

labels:

app: zabbix-server

spec:

containers:

- name: zabbix-server

image: zabbix/zabbix-server-mysql:latest # 官方Zabbix Server镜像（6.4版本）

imagePullPolicy: IfNotPresent

ports:

- containerPort: 10051 # Zabbix Server默认端口

env:

- name: DB_SERVER_HOST

value: "mysql" # 对应MySQL Service名称

- name: MYSQL_DATABASE

value: "zabbix"

- name: MYSQL_USER

value: "zabbix"

- name: MYSQL_PASSWORD

value: "zabbix" # 与MySQL中Zabbix用户密码一致

- name: MYSQL_ROOT_PASSWORD

value: "Root@123" # MySQL root密码（用于初始化数据库）

resources:

requests:

cpu: 300m

memory: 300Mi

limits:

cpu: 1000m

memory: 800Mi

---

apiVersion: v1

kind: Service

[root@k8s-master01 ~]#

（2）应用部署

kubectl apply -f zabbix-server-deploy.yaml

（3）验证 Zabbix Server 状态

kubectl get pods -n zabbix -l app=zabbix-server

3、部署 Zabbix Web 前端（Nginx+PHP）

（1）Zabbix Web 提供可视化界面，需连接 Zabbix Server 和 MySQL。创建zabbix-web-deploy.yaml

[root@k8s-master01 ~]# cat zabbix-web-deploy.yaml

apiVersion: apps/v1

kind: Deployment

metadata:

namespace: zabbix

spec:

replicas: 1

value: "zabbix-server" #对应Zabbix Server Service名称

- name: DB_SERVER_HOST

value: "mysql"

- name: MYSQL_DATABASE

value: "zabbix"

- name: MYSQL_USER

value: "zabbix"

- name: MYSQL_PASSWORD

value: "zabbix"

memory: 256Mi

limits:

cpu: 1000m

memory: 512Mi

---

apiVersion: v1

kind: Service

metadata:

namespace: zabbix

spec:

selector:

app: zabbix-web

ports:

- port: 80

targetPort: 8080

type: NodePort #暴露到节点端口，便于外部访问

[root@k8s-master01 ~]#

（2）应用部署

kubectl apply -f zabbix-web-deploy.yaml

（3）验证 Web 状态

kubectl get pods -n zabbix -l app=zabbix-web

[root@k8s-master01 ~]# kubectl get pods -n zabbix -l app=zabbix-web

NAME READY STATUS RESTARTS AGE

zabbix-web-7bc9f48d8f-7bvvz 1/1 Running 0 27m

[root@k8s-master01 ~]#

4、部署 Zabbix Agent（可选，监控 K8s 节点）

[root@k8s-master01 ~]# cat zabbix-agent-daemonset.yaml

apiVersion: apps/v1

kind: DaemonSet

metadata:

namespace: zabbix

spec:

selector:

matchLabels:

app: zabbix-agent

template:

metadata:

labels:

app: zabbix-agent

spec:

hostNetwork: true

#新增：容忍 master 节点的污点（关键！）

tolerations:

operator: "Exists"

effect: "NoSchedule"

#保留原有其他容忍（内存压力、磁盘压力等，无需修改）

- key: "node.kubernetes.io/memory-pressure"

operator: "Exists"

effect: "NoSchedule"

- key: "node.kubernetes.io/disk-pressure"

operator: "Exists"

effect: "NoSchedule"

#容器配置不变（保留原有内容）

containers:

- name: zabbix-agent

image: zabbix/zabbix-agent:latest

ports:

- containerPort: 10050

env:

- name: ZBX_SERVER_HOST

value: "zabbix-server"

5、访问 Zabbix Web 界面

（1）获取节点 IP（任意 worker 节点或 master 节点均可

[root@k8s-master01 ~]# kubectl get nodes -o wide

NAME STATUS ROLES AGE VERSION INTERNAL-IP EXTERNAL-IP OS-IMAGE KERNEL-VERSION CONTAINER-RUNTIME
