我正在使用MySQL服务器版本：5.5.8-log MySQL社区服务器（GPL）我想记录不使用INDEX的查询，也很慢！我在这里复制我的my.ini设置。

[mysqld]
port=3306
log = "E:/wamp/logs/genquery.log"

[mysqld] port = 3306 log =“E：/wamp/logs/genquery.log”

log_slow_queries
long_query_time = 1
slow_query_log = 1
slow_query_log_file = "E:/wamp/logs/slowquery.log"

log_slow_queries long_query_time = 1 slow_query_log = 1 slow_query_log_file =“E：/wamp/logs/slowquery.log”

对Linux用户可能有用。（Testet：Ubuntu 16.04）

Get root in terminal and edit mysql configuration

获取终端root并编辑mysql配置

su
vim /etc/mysql/conf.d/mysql.cnf

[mysqld]
slow_query_log=1
slow_query_log_file=/var/log/mysql/slow-query.log
long_query_time=1
log_queries_not_using_indexes=1

Add log file and restart mysql server

添加日志文件并重启mysql服务器

touch /var/log/mysql/slow-query.log
chown mysql:adm /var/log/mysql/slow-query.log
chmod 640 slow-query.log
service mysql restart

Test slow logging with SQL queries

使用SQL查询测试慢速日志记录

/* Activate query log - Maybe useful to show errors (not necessary) */
SET GLOBAL SLOW_QUERY_LOG=ON;

/* Check if slow query log is working */
SELECT SLEEP(2);

In addition to a1ex07's answer you can use the shell command mk-query-digest to output a report of your running queries without using the log.

除了a1ex07的答案，您还可以使用shell命令mk-query-digest输出正在运行的查询的报告，而无需使用日志。

As mentioned in the article it is also possible to group the queries by tables doing --group-by tables --report-format profile

正如文章中提到的，还可以通过表格--group-by tables --report-format profile对查询进行分组

Useful to fast detect unindexed queries.

用于快速检测未编制索引的查询。
