废话不多说 直接上代码

import re
import os
import pymongo
import uuid
import bson
def extract_unresolved_info(log_path):
    unresolved_info = []
    with open(log_path, 'r') as file:
        log_text = file.read()
    lines = log_text.split("\n")
    for line in lines:

        # 这种属于主机访问不了 dns找不到解析不了域名或ip 
        if "could not be resolved (3: Host not found)" in line:
            time_match = re.search(r'(\d{4}/\d{2}/\d{2} \d{2}:\d{2}:\d{2})', line)
            ip_match = re.search(r'client: ([\d.]+)', line)
            url_match = re.search(r'request: "GET ([^"]+)', line)
            if time_match and ip_match and url_match:
                unresolved_info.append({
                    'time': time_match.group(1),
                    'ip': ip_match.group(1),
                    'url': url_match.group(1).replace(" HTTP/1.1",""),
                    'type': '1'
                })

        # 这种属于域名或ip访问不了 请求对方失败超时了  dns是能解析域名或者ip的
        if "upstream timed out (110: Connection timed out) while connecting to upstream" in line:
            time_match = re.search(r'(\d{4}/\d{2}/\d{2} \d{2}:\d{2}:\d{2})', line)
            ip_match = re.search(r'client: ([\d.]+)', line)
            url_match = re.search(r'request: "GET ([^"]+)', line)
            if time_match and ip_match and url_match:
                unresolved_info.append({
                    'time': time_match.group(1),
                    'ip': ip_match.group(1),
                    'url': url_match.group(1).replace(" HTTP/1.1",""),
                    'type': '2'
                })


    # 清空日志内容
    with open(log_path, 'w') as file:
        file.write('')

    return unresolved_info

# 连接 MongoDB 并存储数据
client = pymongo.MongoClient("mongodb://xxx:xxxx@127.0.0.1:27017/xxxxxx")
db = client["xxxxxx"] #数据库名称
collection = db["xxxxxx"] # 表名称

log_path = "/usr/local/nginx/logs/error.log" #nginx 日志分析日志地址
lists = extract_unresolved_info(log_path)

for line in lists:
    # 这里插入id的时候使用 uuid并且是str类型 要不然删不了
    line['_id'] =  str(uuid.uuid4())
    collection.insert_one(line)

# 插入完成后断开连接
client.close()
在这里插入代码片

然后就已经实现了获取日志 并且插入到mongodb里面啦

如果有自己的特定需求可以自己去分析和设置 比如在 error.log 里面通过nginx.conf自定义报错日志格式 分割好，然后在python里面进行分割获取数据写入表中
