mysql抓包_mysql抓包工具

简介

MySQL Sniffer 是一个基于 MySQL 协议的抓包工具，实时抓取 MySQLServer 端或 Client 端请求，并格式化输出。输出内容包括访问时间、访问用户、来源 IP、访问 Database、命令耗时、返回数据行数、执行语句等。有批量抓取多个端口，后台运行，日志分割等多种使用方式，操作便捷，输出友好。

同时也适用抓取 Atlas 端的请求，Atlas 是奇虎开源的一款基于MySQL协议的数据中间层项目，项目地址：https://github.com/Qihoo360/Atlas

同类型工具还有vc-mysql-sniffer，以及 tshark 的 -e mysql.query 参数来解析 MySQL 协议。

使用

建议在 centos6.2 及以上编译安装，并用 root 运行。

依赖

glib2-devel、libpcap-devel、libnet-devel

安装

git clone git@github.com:Qihoo360/mysql-sniffer.git

cd mysql-sniffer

mkdir proj

cd proj

cmake ../

make

cd bin/

参数：

./mysql-sniffer -h

Usage mysql-sniffer [-d] -i eth0 -p 3306,3307,3308 -l /var/log/mysql-sniffer/ -e stderr

[-d] -i eth0 -r 3000-4000

-d daemon mode.

-s how often to split the log file(minute, eg. 1440). if less than 0, split log everyday

-i interface. Default to eth0

-p port, default to 3306. Multiple ports should be splited by ','. eg. 3306,3307

this option has no effect when -f is set.

-r port range, Don't use -r and -p at the same time

-l query log DIRECTORY. Make sure that the directory is accessible. Default to stdout.

-e error log FILENAME or 'stderr'. if set to /dev/null, runtime error will not be recorded

-f filename. use pcap file instead capturing the network interface

-w white list. dont capture the port. Multiple ports should be splited by ','.

-t truncation length. truncate long query if it's longer than specified length. Less than 0 means no truncation

-n keeping tcp stream count, if not set, default is 65536. if active tcp count is larger than the specified count, mysql-sniffer will remove the oldest one

示例

1. 实时抓取某端口信息并打印到屏幕

输出格式为：时间，访问用户，来源 IP，访问 Database，命令耗时，返回数据行数，执行语句。

mysql-sniffer -i eth0 -p 3306
