MYSQL-BINLOG
1、如何开启mysql-binlog：
my.ini文件添加：
[mysqld]
log-bin="C:\ProgramData\MySQL\MySQL Server 5.1\data\mysql-bin.log"
执行命令：
C:\ProgramData\MySQL\MySQL Server 5.1\data>mysqladmin flush-logs -u root -p
重启mysql即可
2、查看mysql-binlog文件：
切换到二进制目录文件下：
cd C:\ProgramData\MySQL\MySQL Server 5.1\data
查看二进制：
C:\ProgramData\MySQL\MySQL Server 5.1\data>mysqlbinlog mysql-bin.000001 -d test -u root -p

3、查看主日志文件状态：
mysql> show master logs;
+------------------+-----------+
| Log_name | File_size |
+------------------+-----------+
| mysql-bin.000001 | 207 |
+------------------+-----------+
1 row in set (0.00 sec)
4、查看二进制日志文件：
mysql> show binary logs;
+------------------+-----------+
| Log_name | File_size |
+------------------+-----------+
| mysql-bin.000001 | 250 |
| mysql-bin.000002 | 106 |
+------------------+-----------+
2 rows in set (0.02 sec)
查看二进制log的状态：
mysql> show binlog events\G;
*************************** 1. row ***************************
Log_name: mysql-bin.000001
Pos: 4
Event_type: Format_desc
Server_id: 1
End_log_pos: 106
Info: Server ver: 5.1.28-rc-community-log, Binlog ver: 4
*************************** 2. row ***************************
Log_name: mysql-bin.000001
Pos: 106
Event_type: Query
Server_id: 1
End_log_pos: 207
Info: use `test`; insert into test01 values(19,"daskfj")
*************************** 3. row ***************************
Log_name: mysql-bin.000001
Pos: 207
Event_type: Rotate
Server_id: 1
End_log_pos: 250
Info: mysql-bin.000002;pos=4
3 rows in set (0.00 sec)
ERROR:
No query specified
5、查看当前使用的二进制日志：
mysql> show master status;
+------------------+----------+--------------+------------------+
| File | Position | Binlog_Do_DB | Binlog_Ignore_DB |
+------------------+----------+--------------+------------------+
| mysql-bin.000002 | 106 | | |
+------------------+----------+--------------+------------------+
1 row in set (0.06 sec)
6、清除二进制日志方法：
切换日志：
mysql >flush logs;
Query OK, 0 rows affected (0.39 sec)
mysql> show binary logs;
+------------------+-----------+
| Log_name | File_size |
+------------------+-----------+
| mysql-bin.000001 | 150 |
| mysql-bin.000002 | 107 |
+------------------+-----------+
2 rows in set (0.00 sec)
mysql >reset master; ------清楚所有的二进制文件，相当于重置，以前的日志删除。
Query OK, 0 rows affected (0.38 sec)
mysql> show binary logs;
+------------------+-----------+
| Log_name | File_size |
+------------------+-----------+
| mysql-bin.000001 | 107 |
+------------------+-----------+
1 row in set (0.00 sec)
7、通过bin-log恢复数据：
按照恢复点恢复数据：
C:\Documents and Settings\All Users\Application Data\MySQL\MySQL Server 5.5\data\bin-log>mysqlbinlog --stop-position=749 mysql-bin.000002 | mysql -uroot -p
Enter password:
按照时间点恢复数据：
C:\Documents and Settings\All Users\Application Data\MySQL\MySQL Server 5.5\data\bin-log>mysqlbinlog --stop-datetime="2013-11-24 12:44:29" mysql-bin.000002 | mysql -uroot -p
Enter password:
binlog的删除可以手工删除或自动删除
自动删除binlog
通过binlog参数（expire_logs_days ）来实现mysql自动删除binlog
mysql> show binary logs;
mysql> show variables like 'expire_logs_days';
mysql> set global expire_logs_days=3;
手工删除binlog
mysql> reset master; //删除master的binlog
mysql> reset slave; //删除slave的中继日志
mysql> purge master logs before '2012-03-30 17:20:00'; //删除指定日期以前的日志索引中binlog日志文件
mysql> purge master logs to 'binlog.000002'; //删除指定日志文件的日志索引中binlog日志文件
或者直接用操作系统命令直接删除
