nginx 每天各IP访问次数记录统计-Toy模板网

此文章主要介绍了，在nginx代理的情况下，统计当天IP的出现次数，并且生成表格的相关步骤

1.nginx 配置的修改

在/etc/nginx/nginx.conf

http {
	access_log xxxxxxx/access.log;
    error_log xxxxxxx/error.log;
}

2.定时执行的shell脚本

该脚本主要在每天的0点自动执行IPStatistics.py来记录昨天的IP访问次数，然后对昨天的日志进行备份，并且备份最长时间为maximum_retention_date天；

cut_nginx_log.sh脚本内容如下（分割线上方的变量我们可以根据需要自行配置）：

# function:cut nginx log files
# The original log file path of nginx.conf configuration
log_files_from="xxxxxxx/nginxLog/"
# Path of newly saved log file
log_files_to="xxxxxxx/nginxLog/historyLog/"
# Path to IPStatistics.py script
python_file="xxxxxxxxx/nginxLog/script/IPStatistics.py"
# File name of the log
log_name="access"
# Maximum access.log date saving time, for example, 7 days
maximum_retention_date=`date -d "7 day ago" "+%Y-%m-%d"`


backup_end_time=`date -d yesterday +%Y-%m-%d`
file=${log_files_from}${log_name}.log

if [ -f "$file" ];then
# run python file to generate ip statistics csv, backup files
    python3 ${python_file}&&cp ${log_files_from}${log_name}.log ${log_files_to}${log_name}_${backup_end_time}.log
    :>${log_files_from}${log_name}.log
# delete n days ago nginx log files 
    rm -rf ${log_files_to}${log_name}_${maximum_retention_date}.log
# restart nginx
    systemctl restart nginx
fi

定时执行脚本需要进行如下操作：

# 1.赋予cut_nginx_log.sh执行权限
chmod +x xxxxxx/cut_nginx_log.sh

# 2.使用 crontab 添加定时任务
# (1) 打开定时任务
crontab -e
# (2) 添加定时任务，这里每天凌晨0点执行一次。
00 00 * * * /bin/sh xxxxxx/cut_nginx_log.sh
# (3) 查看定时任务
crontab -l

3.统计当天内的IP访问次数的python 脚本

通过处理access.log的记录，生成IP统计csv文件

#!/usr/bin/env python
# -*- coding:utf-8 -*-
import os.path
import re
import datetime

# nginx access.log文件的位置
log_Path = r"xxxxxxx/access.log"
# 分析access.log后得到的当天Ip访问次数结果，记录的文件路径
statistical_ip_result_file = r"xxxxxxx/statistical_ip_result.csv"
# 多长时间内的IP访问算作一次，单位是小时（例如从某IP当天第一次访问开始，在一个小时内，如果该IP再次访问，依然算作一次访问）
time_interval = 1
# csv文件中最长的IP访问次数保留时间
maximum_retention_time = 180

# 用于解析 access.log的正则表达式（解析为ip,time）
obj = re.compile(r'(?P<ip>.*?)- - \[(?P<time>.*?)\] ')
# 用于存放日志的分析结果(ip,(time1,time2,time3...))
ip_dict = {}
# 用于存放当天日志的ip访问次数
ip_count = {}

                    result = obj.match(log_data)
                    ip = result.group("ip")
