#整体的效果，全局开启表和日志文件都写，但是对于general_log只写表，对于slow_query_log，表和日志文件都记录。
general_log=1#开启mysql执行sql的日志 slow_query_log=1#开启mysql慢sql的日志

#设置之后会影响general_log和slow_query_log，
log_output=table,File#日志输出会写表，也会写日志文件，为了便于程序去统计，所以最好写表

#这里没配置general_log_file，那么general_log就只会写表了
#在mysql5.1.29以上，设置以下即可打开mysql将执行的sql记录在文件中
#general_log_file=/log/general.log

#5.1.29以以前为：
#log=/var/lib/mysql/sql_row.log
long_query_time=1#设置mysql的慢查询为超过1s的查询 slow_query_log_file=/log/slow.log
