打开my.ini文件，位置安装目录下，添加开启日志的配置，重启mysql

# SERVER SECTION

# ----------------------------------------------------------------------

#

# The following options will be read by the MySQL Server. Make sure that

# you have installed the server correctly (see above) so it reads this

# file.

#

[mysqld]

# Set Slow Query Log

long_query_time = 1

slow_query_log = 1

slow_query_log_file = "slowquery.log"

#Set General Log

log = "genquery.log"

slow_query_log_file、log 的文件位置可以自己制定绝对路径，默认在数据文件夹下。

long_query_time单位为秒，即大于1秒的查询语句将记录在slowquery.log文件中。

log 是执行的SQL语句都将记录下来。
