在mysql中记录所有查询

Question

我可以打开我的mysql数据库上的审计日志记录吗？

我基本上想要监视一小时的所有查询,并将日志转储到文件中.

Answer 1

(注意:对于mysql-5.6 +,这不起作用.如果你向下滚动或点击这里,有一个适用于mysql-5.6 +的解决方案.)

如果您不想或无法重新启动MySQL服务器,可以在运行的服务器上继续这样操作:

• 在mysql数据库上创建日志表

  CREATE TABLE `slow_log` (
   `start_time` timestamp NOT NULL DEFAULT CURRENT_TIMESTAMP 
                          ON UPDATE CURRENT_TIMESTAMP,
   `user_host` mediumtext NOT NULL,
   `query_time` time NOT NULL,
   `lock_time` time NOT NULL,
   `rows_sent` int(11) NOT NULL,
   `rows_examined` int(11) NOT NULL,
   `db` varchar(512) NOT NULL,
   `last_insert_id` int(11) NOT NULL,
   `insert_id` int(11) NOT NULL,
   `server_id` int(10) unsigned NOT NULL,
   `sql_text` mediumtext NOT NULL,
   `thread_id` bigint(21) unsigned NOT NULL
  ) ENGINE=CSV DEFAULT CHARSET=utf8 COMMENT='Slow log'

  CREATE TABLE `general_log` (
   `event_time` timestamp NOT NULL DEFAULT CURRENT_TIMESTAMP
                          ON UPDATE CURRENT_TIMESTAMP,
   `user_host` mediumtext NOT NULL,
   `thread_id` bigint(21) unsigned NOT NULL,
   `server_id` int(10) unsigned NOT NULL,
   `command_type` varchar(64) NOT NULL,
   `argument` mediumtext NOT NULL
  ) ENGINE=CSV DEFAULT CHARSET=utf8 COMMENT='General log'

• 启用数据库的查询日志记录

SET global general_log = 1;
SET global log_output = 'table';

• 查看日志

select * from mysql.general_log

• 禁用数据库的查询日志记录

SET global general_log = 0;

Answer 2

除了我在这里遇到的情况,运行以下内容是将查询转储到日志文件而不重新启动的最简单方法

SET global log_output = 'FILE';
SET global general_log_file='/Applications/MAMP/logs/mysql_general.log';
SET global general_log = 1;

可以关闭

SET global general_log = 0;

Answer 3

使用--log选项启动mysql:

mysqld --log=log_file_name

或将以下内容放入您的my.cnf文件中:

log = log_file_name

任何一个都会将所有查询记录到log_file_name.

您也可以使用--log-slow-queries选项而不是使用选项仅记录慢速查询--log.默认情况下,占用10秒或更长时间的查询被认为很慢,您可以通过设置long_query_time查询在记录之前必须执行的秒数来更改此值.

Answer 4

最佳答案在mysql 5.6+中不起作用.请改用:

[mysqld]
general_log = on
general_log_file=/usr/log/general.log

在my.cnf/my.ini文件中

Ubuntu/Debian:/etc/mysql/my.cnf
Windows:c:\ ProgramData\MySQL\MySQL Server 5.x
wamp:c:\ wamp\bin\mysql\mysqlx.yz\my.ini
xampp:c:\ xampp\mysql的\ BIN\my.ini的.

Answer 5

启用表的日志

mysql> SET GLOBAL general_log = 'ON';
mysql> SET global log_output = 'table';

按选择查询查看日志

select * from mysql.general_log

Answer 6

无需重新启动即可快速启用MySQL常规查询日志.

mysql> SET GLOBAL general_log = 'ON';
mysql> SET GLOBAL general_log_file = '/var/www/nanhe/log/all.log';

我已经通过自制软件安装mysql,mysql版本:mysql Ver 14.14 Distrib 5.7.15,for osx10.11(x86_64)使用EditLine包装器

Answer 7

为了记录,在5.1.6中引入了general_log和slow_log:

http://dev.mysql.com/doc/refman/5.1/en/log-destinations.html

5.2.1.选择常规查询和慢查询日志输出目标

从MySQL 5.1.6开始,如果启用了这些日志,MySQL Server可以灵活地控制输出到普通查询日志的目的地和慢查询日志.日志条目的可能目标是日志文件或mysql数据库中的general_log和slow_log表

Answer 8

操作系统/mysql 版本：

$ uname -a
Darwin Raphaels-MacBook-Pro.local 15.6.0 Darwin Kernel Version 15.6.0: Thu Jun 21 20:07:40 PDT 2018; root:xnu-3248.73.11~1/RELEASE_X86_64 x86_64

$ mysql --version
/usr/local/mysql/bin/mysql  Ver 14.14 Distrib 5.6.23, for osx10.8 (x86_64) using  EditLine wrapper

添加日志记录（例如，我认为这不是/var/log/...Mac OS 上的最佳路径，但有效：

sudo vi ./usr/local/mysql-5.6.23-osx10.8-x86_64/my.cnf

[mysqld]
general_log = on
general_log_file=/var/log/mysql/mysqld_general.log

重启Mysql

结果：

$ sudo tail -f /var/log/mysql/mysqld_general.log
