elasticsearch 索引创建脚本

注意 py 代码要和 mapping 目录在同一级，mapping 目录下存放索引库的 json 文件，文件名为index_name.json

py代码

import requests
import json
import os


mapping_folder = "./mapping"
headers = {"Content-Type":"application/json","Accept":"application/json"}
is_append = True

## 新集群host
newClusterHost = ""
## 新集群用户名，可为空
newClusterUser = ""
## 新集群密码，可为空
newClusterPassword = ""


def syn_index(index_name, data):
    # 索引存在则放弃同步
    if exist_index(index_name):
        return
    print("syn_index-start:{}".format(index_name))
    syn_index_res = requests.put("http://" + newClusterHost + ":9200/" + index_name,
                                 auth=(newClusterUser, newClusterPassword),
                                 headers={"content-type": "application/json"},
                                 data=data)
    if syn_index_res.status_code != 200:
        print("syn_index-err:{}".format(syn_index_res.text))
    else:
        print("syn_index-success:{}".format(index_name))


def exist_index(index_name):
    exist_index_res = requests.get("http://" + newClusterHost + ":9200/" + index_name, auth=(newClusterUser, newClusterPassword))
    return exist_index_res.status_code == 200


def select_mapping():
    print("\r\n>> select_mapping running \r\n")
    mapping_list = os.listdir(mapping_folder)

    # 存放 key： index_name value：mapping
    mapping_dic = {}

    for file_name in mapping_list:
        file_path = "{}/{}".format(mapping_folder, file_name)
        with open(file_path, encoding='utf-8') as f:
            if f:
                mapping = json.loads(f.read().strip())
                data = json.dumps(mapping, indent=4, sort_keys=True)
                mapping_dic[file_name.split('.')[0]] = data
    return mapping_dic


def main():
    # 获取 mappings 字典 key 为 index_name
    mapping = select_mapping()
    # 创建索引库
    for k, v in mapping.items():
        syn_index(index_name=k, data=v)
    print("Done for syn indies")


if __name__ == "__main__":
    main()
