How can I start and check my MySQL log?
提问by Johnathan Au
I want to check the log in MySQL to see the queries that are being run by my application. How can I do this? I am using XAMPP and the directory to MySQL is C:\xampp\mysql.

This is what I get when I do show variables like '%log%';

Enable general query log by the following query in mysql command line
在mysql命令行中通过以下查询启用通用查询日志
SET GLOBAL general_log = 'ON';
Now open C:/xampp/mysql/data/mysql.logand check query log
现在打开C:/xampp/mysql/data/mysql.log并检查查询日志
If it fails, open your my.cnffile. For windows its my.inifile and enable it there. Just make sure its in the [mysqld]section
如果失败，请打开您的my.cnf文件。对于 Windows，它的my.ini文件并在那里启用它。只要确保它在该[mysqld]部分
[mysqld]
general_log = 1
Note: In xampp my.inifile can be either found in xampp\mysqlor in c:\windowsdirectory
注意：在 xamppmy.ini文件中可以xampp\mysql在c:\windows目录中或目录中找到

回答by Jappy God
Its given on OFFICIAL MYSQL website.
它在官方 MYSQL 网站上给出。
SET GLOBAL general_log = 'ON';
You can also use custom path:
您还可以使用自定义路径：
[mysqld]
# Set Slow Query Log
long_query_time = 1
slow_query_log = 1
slow_query_log_file = "C:/slowquery.log"
#Set General Log
log = "C:/genquery.log"

Seems like the general query log is the file that you need. A good introduction to this is at http://dev.mysql.com/doc/refman/5.1/en/query-log.html
似乎一般查询日志是您需要的文件。对此的一个很好的介绍是在http://dev.mysql.com/doc/refman/5.1/en/query-log.html

For me, general_log didn't worked. But adding this to my.ini worked
对我来说，general_log 没有用。但是将此添加到 my.ini 工作
[mysqld]
log-output=FILE
slow_query_log = 1
slow_query_log_file = "d:/temp/developer.log"
