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?
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.
