脚本或使用自动化工具来批量添加Zabbix Agent，从而减少手动操作和提高效率

使用API添加主机可以减少人为错误的发生。通过自动化和脚本，可以确保正确的配置被应用到每个主机上，避免了手动操作可能导致的配置错误。

使用前提条件

1、zabbix server端模版已经调试完毕

2、zabbix agent 端配置文件和自定义监控调试完毕

Go获取token

package main

import (
	"bytes"
	"encoding/json"
	"fmt"
	"io/ioutil"
	"net/http"
)

type AuthResponse struct {
	JsonRPC string `json:"jsonrpc"`
	Result  string `json:"result"`
}

func main() {
	zabbixURL := "http://192.168.12.100/zabbix/api_jsonrpc.php"
	username := "your-username"
	password := "your-password"

	// 构建请求的JSON数据
	data := map[string]interface{}{
		"jsonrpc": "2.0",
		"method":  "user.login",
		"params": map[string]string{
			"user":     username,
			"password": password,
		},
		"id": 1,
	}

	// 将数据转换为JSON格式
	payload, err := json.Marshal(data)
	if err != nil {
		fmt.Println("JSON encoding error:", err)
		return
	}

	// 发送POST请求给Zabbix API
	resp, err := http.Post(zabbixURL, "application/json", bytes.NewBuffer(payload))
	if err != nil {
		fmt.Println("API request error:", err)
		return
	}
	defer resp.Body.Close()

	// 读取响应的内容
	body, err := ioutil.ReadAll(resp.Body)
	if err != nil {
		fmt.Println("Response read error:", err)
		return
	}

	// 解析响应的JSON数据
	var authResp AuthResponse
	err = json.Unmarshal(body, &authResp)
	if err != nil {
		fmt.Println("JSON decoding error:", err)
		return
	}

	// 输出令牌（token）
	fmt.Println("Token:", authResp.Result)
}

1、获取模版ID和组ID

[root@ops-public zabbix]# cat template-group.sh 

ZABBIX_URL="http://192.168.12.100/zabbix"
username := "your-username"
password := "your-password"
# 登录获取认证令牌
AUTH_TOKEN=$(curl -s -X POST -H 'Content-Type: application/json' -d '{
  "jsonrpc": "2.0",
  "method": "user.login",
  "params": {
    "user": "'"$USER"'",
    "password": "'"$PASSWORD"'"
  },
  "id": 1
}' "$ZABBIX_URL/api_jsonrpc.php" | jq -r '.result')

# 获取模板列表
TEMPLATE_RESULT=$(curl -s -X POST -H 'Content-Type: application/json' -d '{
  "jsonrpc": "2.0",
  "method": "template.get",
  "params": {
    "output": ["templateid", "name"]
  },
  "auth": "'"$AUTH_TOKEN"'",
  "id": 1
}' "$ZABBIX_URL/api_jsonrpc.php")

echo "Template List:"
echo "$TEMPLATE_RESULT" | jq -r '.result[] | "Template ID: \(.templateid), Name: \(.name)"'

# 获取主机组列表
HOSTGROUP_RESULT=$(curl -s -X POST -H 'Content-Type: application/json' -d '{
  "jsonrpc": "2.0",
  "method": "hostgroup.get",
  "params": {
    "output": ["groupid", "name"]
  },
  "auth": "'"$AUTH_TOKEN"'",
  "id": 1
}' "$ZABBIX_URL/api_jsonrpc.php")

echo "Hostgroup List:"
echo "$HOSTGROUP_RESULT" | jq -r '.result[] | "Hostgroup ID: \(.groupid), Name: \(.name)"'

2、批量添加主机

添加到Virtual machines

挂载模版 ID为 10001和10274

[root@ops-public zabbix]# cat add_hosts.sh 

#!/bin/bash
ZABBIX_URL="http://192.168.12.100/zabbix/api_jsonrpc.php"
username := "your-username"
password := "your-password"

TOKEN=$(curl -s -X POST -H 'Content-Type: application/json' -d '{
  "jsonrpc": "2.0",
  "method": "user.login",
  "params": {
    "user": "'"$USER"'",
    "password": "'"$PASSWORD"'"
  },
  "id": 1
}' "$ZABBIX_URL" | jq -r '.result')

NET="192.168.12."

for HOST in $(seq 200 210); do
  HOST_IP="$NET$HOST"

  RESPONSE=$(curl -s -X POST -H "Content-Type: application/json" -d '{
    "jsonrpc": "2.0",
    "method": "host.create",
    "params": {
      "host": "'"$HOST_IP"'",
      "name": "'"$HOST_IP"'",
      "interfaces": [
        {
          "type": 1,
          "main": 1,
          "useip": 1,
          "ip": "'"$HOST_IP"'",
          "dns": "",
          "port": 10050
        }
      ],
      "groups": [
        {
          "groupid": "6"
        }
      ],
      "templates": [
        {
          "templateid": "10274"
        },
        {
          "templateid": "10001"
        }
      ]
    },
    "id": 1,
    "auth": "'"$TOKEN"'"
  }' "$ZABBIX_URL")

  HOST_ID=$(echo "$RESPONSE" | jq -r '.result.hostids[0]')
  HOST_NAME=$(echo "$RESPONSE" | jq -r '.result.hosts[0].host')

  echo "Added host $HOST_NAME with ID $HOST_ID"
done

批量添加主机并挂载模版

除了使用api方式，也可以使用自动注册主机来完成主机注册。
