MySQL Enterprise Backup (MEB) Lifecycle

MySQL Enterprise Backup 8.0.21 only supports MySQL 8.0.21.
For earlier verions of MySQL 8.0, use the MySQL Enterprise Backup version with the same version number as the server.
For MySQL 5.7, use MySQL Enterprise Backup 4.1.
For MySQL 5.6, use MySQL Enterprise Backup 3.12.

Install (Linux)

Unpack meb-{version}-el6-x86-64bit.tar.gz to /mysql/mysql-backup

cd /mysql

unzip ${ZIPFILE}

tar xvf ${TARFILE}

ln -s /mysql/$(echo ${TARFILE} | awk -F".tar" '{ print $1 }') /mysql/mysql-backup

mv README.txt /mysql/mysql-backup

rm -f ${TARFILE} ${TARFILE}.asc ${TARFILE}.md5 ${ZIPFILE}

export PATH=/mysql/mysql-backup/bin:$PATH

Add this to the .bash_profile for the root user

vi /root/.bash_profile

Add backup user to MySQL

For MySQL < 8.0

CREATE USER 'backup'@'myserver';

GRANT RELOAD ON *.* TO 'backup'@'myserver';

GRANT CREATE, INSERT, DROP, UPDATE ON mysql.ibbackup_binlog_marker TO 'backup'@'myserver';

GRANT CREATE, INSERT, DROP, UPDATE ON mysql.backup_progress TO 'backup'@'myserver';

GRANT CREATE, INSERT, SELECT, DROP, UPDATE ON mysql.backup_history TO 'backup'@'myserver';

GRANT REPLICATION CLIENT ON *.* TO 'backup'@'myserver';

GRANT SUPER ON *.* TO 'backup'@'myserver';

GRANT CREATE TEMPORARY TABLES ON mysql.* TO 'backup'@'myserver';

FLUSH PRIVILEGES;

For MySQL 8.0.19+

CREATE USER 'mysqlbackup'@'localhost' IDENTIFIED BY RANDOM PASSWORD;

CREATE USER 'mysqlbackup'@'node1' IDENTIFIED BY 'samepasswordasabove';

CREATE USER 'mysqlbackup'@'node2' IDENTIFIED BY 'samepasswordasabove';

CREATE USER 'mysqlbackup'@'node3' IDENTIFIED BY 'samepasswordasabove';

GRANT SELECT, RELOAD, PROCESS, SUPER, REPLICATION CLIENT

ON *.*

TO 'mysqlbackup'@'localhost',

'mysqlbackup'@'node1',

'mysqlbackup'@'node2',

'mysqlbackup'@'node2';

GRANT BACKUP_ADMIN

ON *.*

TO 'mysqlbackup'@'localhost',

'mysqlbackup'@'node1',

'mysqlbackup'@'node2',

'mysqlbackup'@'node2';

GRANT CREATE, INSERT, DROP, UPDATE

ON mysql.backup_progress

TO 'mysqlbackup'@'localhost',

'mysqlbackup'@'node1',

'mysqlbackup'@'node2',

'mysqlbackup'@'node2';

GRANT CREATE, INSERT, DROP, UPDATE, SELECT, ALTER

ON mysql.backup_history

TO 'mysqlbackup'@'localhost',

'mysqlbackup'@'node1',

'mysqlbackup'@'node2',

'mysqlbackup'@'node2';

Note that the requirement for multiple users is to allow the backup to run from any node in an innodb cluster and for the backup history to be synchronised across all nodes in the cluster.
Note also that the hostname for "node1","node2" etc should be the fully qualified name including domain information...hostname --fqdn
Note that you are likely to see this warning message (which can be ignored... at some point the MySQL documentation will, presumably, be updated with an updated set of GRANTs)... Warning (code 1287): The SUPER privilege identifier is deprecated:

Note: For release 8.0.12 to 8.0.18 there are some additional GRANTs required...GRANT SELECT ON performance_schema.replication_group_members TO 'mysqlbackup'@'myserver';
GRANT SELECT ON performance_schema.variables_info TO 'mysqlbackup'@'myserver';
GRANT SELECT ON performance_schema.log_status TO 'mysqlbackup'@'myserver';

Store Password

Securely store password for mysqlbackup user...

Do this on every node in an innodb cluster so that backups still work after a failover/switchover

mysql_config_editor set --login-path=mysqlbackup --user=mysqlbackup --password
