How to enable MySQL Query Log?

Question

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 N

Answer 1

In phpMyAdmin 4.0, you go to Status > Monitor. In there you can enable the slow query log and general log, see a live monitor, select a portion of the graph, see the related queries and analyse them.

Answer 2

// To see global variable is enabled or not and location of query log    
SHOW VARIABLES like 'general%';
// Set query log on 
SET GLOBAL general_log = ON; 

Answer 3

This was already in a comment, but deserves its own answer: Without editing the config files: in mysql, as root, do

SET global general_log_file='/tmp/mysql.log'; 
SET global log_output = 'file';
SET global general_log = on;

Don't forget to turn it off afterwards:

SET global general_log = off;

Answer 4

You can disable or enable the general query log (which logs all queries) with

SET GLOBAL general_log = 1 # (or 0 to disable)

Answer 5

for mysql>=5.5 only for slow queries (1 second and more) my.cfg

[mysqld]
slow-query-log = 1
slow-query-log-file = /var/log/mysql/mysql-slow.log
long_query_time = 1
log-queries-not-using-indexes

Answer 6

I also wanted to enable the MySQL log file to see the queries and I have resolved this with the below instructions

1. Go to /etc/mysql/mysql.conf.d
2. open the mysqld.cnf

and enable the below lines

general_log_file        = /var/log/mysql/mysql.log
general_log             = 1

3. restart the MySQL with this command /etc/init.d/mysql restart
4. go to /var/log/mysql/ and check the logs
