值得一提的是，general_log和slow_log是在5.1.6中引入的:

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

5.2.1. 选择常规查询和慢速查询日志输出目的地 从MySQL 5.1.6开始，MySQL服务器提供了灵活的控制 输出到一般查询日志和慢速查询日志的目的地， 如果启用了这些日志。日志条目的可能目的地是 日志文件或mysql中的general_log和slow_log表 数据库

(注意:对于mysql-5.6+，这将不起作用。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。)

如果你不想或者不能重新启动MySQL服务器，你可以在你正在运行的服务器上这样做:

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

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

查看日志

select * from mysql.general_log

禁用数据库查询日志

SET global general_log = 0;

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，我不认为/var/log/…是Mac OS上的最佳路径，但这是有效的:

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

重新启动Mysql

结果:

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

更新:不再适用于mysql 5.6+

使用——log选项启动mysql:

mysqld --log=log_file_name

或者将以下内容放在my.cnf文件中:

log = log_file_name

任何一个都将把所有查询记录到log_file_name。

您也可以使用——log-slow-queries选项而不是——log只记录慢查询。默认情况下，需要10秒或更长时间的查询被认为是慢查询，您可以通过将long_query_time设置为查询在被记录日志之前必须执行的秒数来改变这一点。

快速启用MySQL常规查询日志，无需重新启动。

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

我已经通过homebrew安装mysql, mysql版本:mysql Ver 14.14 Distrib 5.7.15，用于osx10.11 (x86_64)使用EditLine包装器。

顶部的答案不工作在mysql 5.6+。用这个代替:

[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 mysql wamp: c: \ wamp \ bin \ \ mysqlx.y.z \ my.ini mysql xampp: c: \ xampp \ \ bin \ my.ini。
