MySQL – How to Disable Binary Logging with log_bin Variable

binlogdebianlogsMySQL

Default MySQL config file /etc/mysql/my.cnf installed by some debian package using APT often set log_bin variable, so binlog are enabled:

log_bin = /var/log/mysql/mysql-bin.log

When I want to disable binary logging on such installation, comment out the line in my.cnf works of course, but I wonder if there is a way to disable binary logging by setting explicitely log_bin to OFF, in a debian style, I mean in an included file like /etc/mysql/conf.d/myCustomFile.cnf, so default my.cnf is not changed and can be easily updated by apt, if necessary.

I tried "log_bin = 0", "log_bin = OFF" or "log_bin =" but none works…

This is an old question, but it came up in a search while I was trying to jog my memory about the correct option name and so now that I've figured it out I'm adding the details here.

The key part of the question is:

I mean in an included file like /etc/mysql/conf.d/myCustomFile.cnf

You can do this from an included option file using the option skip-log-bin. E.g. you might create /etc/mysql/conf.d/disable_binary_log.cnf with the following contents:

[mysqld]
skip-log-bin

You can add skip- as a prefix to other options to disable them in this way too.
