How can I enable the binary log tabin phpmyadmin 5.0.1?
The Phpmyadmin application does not have a log file, however you can perform this trick:
Phpmyadmin has a php script that when executed will return a result with the errors you find.
On Ubuntu Server the file is in:
/usr/share/phpmyadmin/error_report.php then you must enter that folder and run
this will return the errors that Phpmyadmin has, most of the time they are errors in the configuration file config.inc.php
What problem are you seeing with phpMyAdmin that you hope to fix by viewing the log? You haven’t really described what problem you’re trying to solve, which makes answering your question a bit difficult.
There are a number of logs available, but the most direct answer about the log file to check regarding errors with phpMyAdmin is in your webserver’s error log. Read on for more details, though.
If it’s a problem within phpMyAdmin directly (or something that phpMyAdmin does with MySQL), it’s usually shown directly on the screen as a friendly message. If it’s something that breaks phpMyAdmin directly, it’s logged through whatever means you have configured for PHP errors to be logged (usually directly to the webserver error log).
If you’re having a problem with a query through MySQL, those are logged by MySQL through the MySQL error log, which is usually to a file in most systems I’m familiar with.
The binary log is not related to error logging, but is instead an ongoing transaction log where MySQL records ongoing queries (docs, more docs). Based on your description, this is not what you’re looking for.
Can anyone confirm that phpMyAdmin, However in my config.php file for phpMyAdmin Edit config.inc.php didn’t work, similary as reinstall phpmyadmin, apache or mysql. Only way is using password to log in to phpmyadmin sudo zypper update sudo zypper install mariadb mariadb-client mariadb-tools sudo systemctl start mysql sudo …
Can’t enable MySql general query log file on wamp running mysql 5.6
You have a typo in general-log . It should be general_log
And check your variables, after a restart such as
select @@general_log; -- 0 (that means OFF). 1 is ON. select @@general_log_file; -- GUYSMILEY.log select @@datadir; -- C:\ProgramData\MySQL\MySQL Server 5.6\Data\ select @@version; -- 5.6.31-log To set a dynamic variable to override a cnf or ini file setting, do something similar to:
Remember that it is datadir , not basedir . You may need to open up the viewing of hidden folders on Windows to see the \ProgramData if that is where you datadir points.
And lastly, you don’t need to trick it with an error sql statement. The General Query Log is for all queries.
For a screenshot view of it, see This Answer. Remember, it is for all queries. So turn it off, make a copy, delete, turn back on, it regenerates. Don’t forget too that having the General Log activated in production slows down performance.
Also, see this answer from Gryphius.
Edit (per your question in comments).
Changes to dynamic variables are fleeting if not mirrored in cnf or ini settings. Meaning, they are reset upon mysql restarting.
I don’t know a way to turn off Error logging nor would I probably want to. Errors are infrequent and knowledge of them is quite important. So the below should satisfy 3 of your 4 curiosities:
show variables like '%error%'; show variables like '%slow%'; log_error -- string for filename slow_query_log -- set to 'ON' or 1, 'OFF' or 0 slow_query_log_file; --- string for filename Then there is always show variables;
More on the slow query log. If you set the long_query_time high enough, it will effectively filter out more noise. It is in seconds, from 0 to 10. And a Percona article though dated.
select @@long_query_time; +-------------------+ | @@long_query_time | +-------------------+ | 10.000000 | +-------------------+ Note, I can’t seem to set the above with a SET GLOBAL stmt. So it appears to be a setting only for the cnf or ini file. But you can do the following:
select @@slow_query_log; -- to see current value select @@slow_query_log_file; -- to see current value (file in datadir) select @@datadir; -- to see current value set global slow_query_log=0; -- Turn Off -- make a backup of it with a move and rename (See Note1) to a folder below datadir set global slow_query_log=1; -- Turn it back On (new empty file is created) Note1: Image of file copied, renamed at Note1 point-in-time above.

Where can I find the MySQL log file in XAMPP, The accepted answer is a bit old, for MySQL 5.1+. you may use the queries: SET GLOBAL general_log = ‘ON’; SET GLOBAL general_log_file = ‘my_log.log’; First will enable loging (which may be off by default) and the second select updates the preferred file (by default under C:/xampp/mysql/data/).

How to disable MySQL error logging?
To find error log location, run the below command
mysql> show global variables like ‘%log_error%’;
As you mentioned, set GLOBAL general_log = 0 — this command used to disable general log. Since it is a space issue, identify, whether it is due to error log or general log. If general log, disable it, if it’s due to error log; flush and rename the error log.
Note: If you flush the logs using FLUSH LOGS or FLUSH ERROR LOGS commands, the MySQL will closes and reopens the error log, but it will keep on writing to same error log file.
In order to create a new file, rename the original file before performing the FLUSH operation , so that, when you run FLUSH LOGS or FLUSH ERROR LOGS the MySQL will close and open new file and start writing to new file.
mv /var/log/mysql/error.log /var/log/mysql/error_old.log mysqladmin flush-logs If the error log file size keep on increasing, the root cause should be identified and removed. Managing the size is not a solution, just a temporary workaround. Open the error log and start debugging and remove the errors, this will keep the error log size within limit.
If troubleshooting errors not in your hand, just make the FLUSHING operation as scheduled task and take backup of the error log. This can be done as below:
mv /var/log/mysql/error.log /var/log/mysql/error_old.log mysqladmin flush-logs mv /var/log/mysql/error_old.log /backupdir I hope this answer will help you, Thanks!
MySQL connection not working: 2002 No such file or, Start Apache HTTP with sudo apachectl start (or restart if it’s already started and needs to be restarted to re-read the configuration file). Make sure that /var/log/apache2/error_log contains a line that tells you the php5_module is enabled — you should see PHP/5.3.15 (or similar).
