Mysql config adjustment

By default mysql will have binary logging enabled. This will take up a lot of disk with very little benefit since mysql is only used for bluemap data.

Add skip-log-bin to /etc/mysql/mysql.conf.d/mysqld.cnf under the [mysqld] section and restart the service.

Example

[mysqld]
pid-file        = /var/run/mysqld/mysqld.pid
socket          = /var/run/mysqld/mysqld.sock
datadir         = /var/lib/mysql
log-error       = /var/log/mysql/error.log
skip-log-bin
