Mysql开启log-bin日志
二、general_log 记录增删改查所有日志 general log
一 、logbin日志
show binary logs;
show master status;
show binlog events in 'mysql-bin.000090' from 242985028 limit 0,1000
- 1、检查是否开启
检查是否开启
show global variables like '%log_bin%';
log_bin 为 on 则已开启，为 off则未开启。
查询所有日志文件
show binary logs;
查询最近日志文件
show master status;
- 2、开启log-bin日志记录
找到my.cnf 中 [mysqld] 添加如下
# binlog 配置
log-bin = D:\\ProgramFiles\\mysql-5.7.20-winx64\\logs\\mysql-bin.log
expire-logs-days = 14
max-binlog-size = 500M
server-id = 1
- 3、查询
SHOW BINLOG EVENTS [IN 'log_name'] [FROM pos] [LIMIT [offset,] row_count]
mysql> show binlog events in 'mysql-bin.000001' from 4 limit 0,5;
+------------------+-----+----------------+-----------+-------------+---------------------------------------+
| Log_name | Pos | Event_type | Server_id | End_log_pos | Info |
+------------------+-----+----------------+-----------+-------------+---------------------------------------+
| mysql-bin.000001 | 4 | Format_desc | 1 | 123 | Server ver: 5.7.20-log, Binlog ver: 4 |
| mysql-bin.000001 | 123 | Previous_gtids | 1 | 154 | |
| mysql-bin.000001 | 154 | Anonymous_Gtid | 1 | 219 | SET @@SESSION.GTID_NEXT= 'ANONYMOUS' |
| mysql-bin.000001 | 219 | Query | 1 | 292 | BEGIN |
| mysql-bin.000001 | 292 | Table_map | 1 | 375 | table_id: 125 (test.ins_car_team) |
+------------------+-----+----------------+-----------+-------------+---------------------------------------+
5 rows in set (0.00 sec)

4、导出文件
mysqlbinlog /var/lib/mysql/mysql-bin.000001 > test.sql;
表更新时间（mysql 5.7.2以下版本无效 ）
select TABLE_NAME,UPDATE_TIME from information_schema.TABLES where TABLE_SCHEMA='databaseTest' order by UPDATE_TIME desc limit 10;
二、general_log日志
是否开启 general_log日志
show variables where variable_name like "%general_log%" or variable_name="log_output";
开启
set global general_log = on;
set global log_output = "table";
查看sql
select * from mysql.general_log where argument like '%select%' ORDER BY event_time DESC limit 100;
