WAMP server. Very large data directory in MySQL?
I have problem with wammp server. In directory "..\WampServer\bin\mysql\mysql5.5.8\data" was created files with very large size. Full size of this directory is 50GB. What is these files? How can I fix this problem?
The names of files are:
mysql-bin.000001 mysql-bin.000002 ................ mysql-bin.000227
The size of all files is 49GB
Thanks in advance!
By default whenever you make a change to a MySQL database it creates a log of the query and stores it in a file simlare to mysql-bin.000001. The MySQL database does this so that you can recover or replicate a database. Most applications this is a good things to have enabled just like doing regular backups.
If you want to disable MySQL from creating these binary logs:
- Open my.ini
- Search for this line log-bin=mysql-bin
- Comment this line out by adding a hash mark: # log-bin=mysql-bin
- Save and restart the MySQL database
You can now safely delete these files from that directory.
I did another thing on my wamp... http://dev.mysql.com/doc/refman/5.0/en/purge-binary-logs.html
Start a command prompt and goto directory wamp\bin\mysql\mysql5.5.16 or whatever version number you got
mysql.exe -u root SHOW BINARY LOGS;
a list with all the log files will be show up. We need the last one. In my case was mysql-bin.000412
so i typed
PURGE BINARY LOGS TO 'mysql-bin.000412';
and you are ok!
