最近有发现有坏蛋delete 了数据,找不到是哪个user 哪个host,发现mysql 是可以对没有super 权限的用户开启审计功能,Oracle早就实现了,只需要打开参数即可。

1.在my.cnf [mysqld]组下加入

init-connect='insert intoaduit.accesslog(id,time,localname,matchname)values(connection_id(),now(),user(),current_user()); 

#create database accesslog;

CREATE TABLE aduit.accesslog (`id` int(11) primary keyauto_increment, `time` timestamp, `localname` varchar(30), `matchname`varchar(30))engine=innodb;

2.被审计的用户需要有insert aduit.accesslog 权限

grant insert on aduit.accesslog to hhl@'172.17.62.%' identified by'xxx';

3.只能审计普通用户没有super权限的用户的DDL,DML,还用开启binlog 分析。

 

[root@wy ~]# mysql -upxy -p -P3306 -h 10.45.247.81

Enter password:

Welcome to the MySQL monitor. Commands end with ; or \g.

mysql> insert into test.t10 values(10);

Query OK, 1 row affected (0.00 sec)

#上面client 连接Processid = 11

mysql> select * from aduit.accesslog;

+----+---------------------+---------------------+-----------+

| id | time                |localname          | matchname |

+----+---------------------+---------------------+-----------+

|  3 | 2014-09-24 17:16:06 |admin@10.45.247.160 | admin@%  |

| 11 | 2014-09-24 17:28:13 |pxy@10.45.247.160  | pxy@%    |

+----+---------------------+---------------------+-----------+

Processid = 11

mysql> show processlist;

+----+-----------------+---------------------+------+---------+------+------------------------+------------------+

| Id | User           | Host                | db  | Command | Time | State                  | Info            |

+----+-----------------+---------------------+------+---------+------+------------------------+------------------+

|  2 | root            | localhost          | NULL | Query  |    0| NULL                  | showprocesslist |

| 11 | pxy            | 10.45.247.160:53086 | NULL |Sleep  |  26 |                        | NULL            |

+----+-----------------+---------------------+------+---------+------+------------------------+------------------+

看到了id=11的吧,就是aduit.accesslog 表的id列。

通过解析 binlog

[root@localhost binlog]# mysqlbinlog --base64-output=decode-rows -v-v mysql-bin.000030 |grep  -nthread_id=11

22:#140924 17:28:13 server id 114 end_log_pos 282  Query  thread_id=11    exec_time=0 error_code=0

24:SET @@session.pseudo_thread_id=11/*!*/;

42:#140924 17:32:21 server id 114 end_log_pos 491  Query  thread_id=11    exec_time=0 error_code=0

定位到模糊的行位置,再找到binlog中Processid = 11 的操作。

Adding MySQL users through the PHP web interface can use MySQLi extensions. The steps are as follows: 1. Connect to the MySQL database and use the MySQLi extension. 2. Create a user, use the CREATEUSER statement, and use the PASSWORD() function to encrypt the password. 3. Prevent SQL injection and use the mysqli_real_escape_string() function to process user input. 4. Assign permissions to new users and use the GRANT statement.

mPDF

mPDF

mPDF is a PHP library that can generate PDF files from UTF-8 encoded HTML. The original author, Ian Back, wrote mPDF to output PDF files "on the fly" from his website and handle different languages. It is slower than original scripts like HTML2FPDF and produces larger files when using Unicode fonts, but supports CSS styles etc. and has a lot of enhancements. Supports almost all languages, including RTL (Arabic and Hebrew) and CJK (Chinese, Japanese and Korean). Supports nested block-level elements (such as P, DIV),
