# docker-mariadb-backup-slave
|
|
|
|
Setup a mariadb slave server with automysqlbackup
|
|
|
|
|
|
## Parameters
|
|
### SERVER_ID
|
|
This is used to customize slave server ID. The default value is 33. You should use an unique ID for each server.
|
|
### READONLY
|
|
When set to **1**, the slave server is set as readonly. This is the default. If you set this variable to something different, the database will be read/write.
|
|
### REPLICATE_DO_DB
|
|
This is used to specify a single database to backup. It is generally advised to set this variable to the database name you want to backup.

2019-11-24 10:57:24 0 [Warning] Neither --relay-log nor --relay-log-index were used; so replication may break when this MySQL server acts as a slave and has his hostname changed!! Please use '--log-basename=#' or '--relay-log=mysqld-relay-bin' to avoid this problem.
