                  问题描述

                  如何启用记录从客户端收到的每个SQL查询语句以及查询语句提交时间的MySQL功能?我可以在 phpmyadmin 或 NaviCat 中这样做吗?如何分析日志?

                  How do I enable the MySQL function that logs each SQL query statement received from clients and the time that query statement has submitted? Can I do that in phpmyadmin or NaviCat? How do I analyse the log?

                  推荐答案

                  首先,请记住,此日志文件在繁忙的服务器上可能会变得非常大.

                  对于 mysql <5.1.29:

                  要启用查询日志,请将其放在[mysqld]部分的/etc/my.cnf

                  To enable the query log, put this in /etc/my.cnf in the [mysqld] section

                  log   = /path/to/query.log  #works for mysql < 5.1.29
                  

                  另外,从 MySQL 控制台启用它

                  Also, to enable it from MySQL console

                  SET general_log = 1;
                  

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

                  对于 mysql 5.1.29+

                  在 mysql 5.1.29+ 中,不推荐使用 log 选项.要指定日志文件并启用日志记录,请在 [mysqld] 部分的 my.cnf 中使用它:

                  With mysql 5.1.29+ , the log option is deprecated. To specify the logfile and enable logging, use this in my.cnf in the [mysqld] section:

                  general_log_file = /path/to/query.log
                  general_log      = 1
                  

                  或者,从 MySQL 控制台打开日志记录(还必须以某种方式指定日志文件位置,或找到默认位置):

                  Alternately, to turn on logging from MySQL console (must also specify log file location somehow, or find the default location):

                  SET global general_log = 1;
                  

                  另请注意,还有其他选项可以仅记录慢速查询或不使用索引的查询.

                  Also note that there are additional options to log only slow queries, or those which do not use indexes.
