在项目开发里面总是要查看后台执行的sql语句，mysql数据库也不例外，它的查看方式大家一般喜欢使用 showprocesslist; 命令来解决，通过里面输出结果的字段解释中可以分析执行了的sql语句类型，但不太适合一般的初级使用者，，因此通过日志文件查看sql语句是最直接的方法。

首先你需要创建一个日志文件log.txt ，比如我直接保存在mysql目录下的data目录中间，然后只需要在 mysql的配置文件my.cnf 中最后添加

log=/var/log/mysql/mysqlProcess.log

这样可以记录所有的mysql执行的sql语句!

log=/var/log/mysql/mysqlProcess.log

添加在[mysqld]块中

需要手动建立此文件，然后chown mysql:mysql，权限修改为跟mysqld.log相同
