MariaDB-找不到innodb_log_file_size

Question

I'm currently installing OTRS on Raspbian. I got it working with Ubuntu and MySQL, but its giving me problems with Raspbian and MariaDB. I cant seem to find the innodb_log_file_size anywhere to change the size of it.

My my.cnf looks like this:

The MariaDB configuration file

The MariaDB/MySQL tools read configuration files in the following order:
1. "/etc/mysql/mariadb.cnf" (this file) to set global defaults,
2. "/etc/mysql/conf.d/*.cnf" to set global options.
3. "/etc/mysql/mariadb.conf.d/*.cnf" to set MariaDB-only options.
4. "~/.my.cnf" to set user-specific options.

If the same option is defined multiple times, the last one will apply.

One can use all long options that the program supports.
Run program with --help to get a list of available options and with
--print-defaults to see which it would actually understand and use.


This group is read both both by the client and the server
use it for options that affect everything

[client-server]
 Import all .cnf files from configuration directory
!includedir /etc/mysql/conf.d/
!includedir /etc/mysql/mariadb.conf.d/

and using show variables like 'innodb_log_file_size'; in mariadb gives me this:

MariaDB [(none)]> show variables like 'innodb_log_file_size';
+----------------------+----------+

| Variable_name        | Value    |

+----------------------+----------+
| innodb_log_file_size | 50331648 |
+----------------------+----------+
1 row in set (0.01 sec)

Any tips to change it? Because I need to get rid of the error:

"Error: Please set the value for innodb_log_file_size on your database to at least 256 MB"

Answer 1

You say there is a "problem" and an "error"; please provide the text of the error and/or other clues.

50M is a decent size for innodb_log_file_size . It can be set in the [mysqld] section of my.cnf.

For very busy systems, it should be higher; for TEXT or BLOB columns over 5MB in size, it should be higher. But for most systems, 48M is plenty big.

The setting is one of the hardest to change, so don't without a good reason.

Once you have been running for some time, compute

 ( Uptime / 60 * innodb_log_file_size / Innodb_os_log_written )

to seem how many minutes between log rotations. 1 hour is a reasonable target.
