Migrate data from another MySQL server into the local one using
|
||
|
|
os-config-applier and os-refresh-config.
|
||
|
|
|
||
|
|
Please note the migration process is *destructive* to any data currently
|
||
|
|
in the MySQL database running on the target host. Safeguards are in
|
||
|
|
place to ensure the process only happens once on any machine.
|
||
|
|
|
||
|
|
Configuration
|
||
|
|
-------------
|
||
|
|
|
||
|
|
Pass in Heat Metadata with the following structure in the
|
||
|
|
OpenStack::Config sub-key.
|
||
|
|
|
||
|
|
mysql:
|
||
|
|
users:
|
||
|
|
root:
|
||
|
|
username: rootuser
|
||
|
|
password: XXXXXXX
|
||
|
|
dump:
|
||
|
|
username: dumpuser
|
||
|
|
password: XXXXXXX
|
||
|
|
mysql-migration:
|
||
|
|
bootstrap_host: x.y.z
|
||
|
|
slave_user: slave-bot1
|
||
|
|
slave_password: XXXXXXXX
|
||
|
|
|
||
|
|
The migration process assumes `dump` and `root` exist on the
|
||
|
|
`bootstrap_host` and have access from this host.
|
||
|
|
|
||
|
|
The `dump` user will be used to dump data from `bootstrap_host`. The
|
||
|
|
`root` user will be used for localhost access after the database is
|
||
|
|
migrated. If `slave_user` and `slave_password` are set to non-empty
|
||
|
|
strings, replication will be setup against the `bootstrap_host` using
|
||
|
|
this user/password combination.
|
||
|
|
|
||
|
|
Special /root/.my.cnf
|
||
|
|
---------------------
|
||
|
|
|
||
|
|
As a convenience, we copy the given `dump` and `root` user names and
|
||
|
|
passwords to /root/.my.cnf after migration. If this file is overwritten,
|
||
|
|
they will also be available as /root/metadata.my.cnf
