MySQL Configuration File

/opt/bitnami/mysql/my.cnf

Some configuration overrides are stored in

/opt/bitnami/mysql/bitnami/my.cnf.

MySQL Socket - On Unix, MySQL clients can connect to the server in the local machine using an Unix socket file at

/opt/bitnami/mysql/tmp/mysql.sock

MySQL Process Identification Number - The MySQL .pid file allows other programs to find out the PID (Process Identification Number) of a running script. Find it at

/opt/bitnami/mysql/data/mysqld.pid

MySQL Error Log - The log-error file contains information indicating when mysqld was started and stopped and also any critical errors that occur while the server is running. If mysqld notices a table that needs to be automatically checked or repaired, it writes a message to the error log.

/opt/bitnami/mysql/data/mysqld.log

How to Backup and Restore Bitnami Mysql Database

---

https://docs.bitnami.com/ibm/apps/redmine/administration/backup-restore-mysql-mariadb/

Backup

To back up just the application database, create a dump file using the mysqldump tool. In this example, the database is named bitnami_app; replace this with the name of the database you wish to export.

mysqldump -u root -p bitnami_app > backup.sql

To back up all the databases, use this command instead:

mysqldump -A -u root -p > backup.sql

This operation could take some time depending on the database sizes.

   NOTE: The steps previously described will only back up the data contained inside your databases. There may be other files that you should take into account when performing a full backup, such as files that may have been uploaded to your application. Refer to your application’s documentation for more details.

Restore

Once you have the backup file, you can restore the data with a command like the one below:

mysql -u root -p < backup.sql

To restore the data to a specific database, include the database name in the command, as shown below. For example, to import the data to a database named bitnami_app, use this command:

mysql -u root -p -D bitnami_app < backup.sql
