i want to run a mysql command START SLAVE; is it possible开发者_Go百科 to do that?
As long as the master is properly configured it's ok to restart the slaves. They will automatically reissue the "START SLAVE" on restart.
I think if there are replication errors, you may have to fix them or reset replication before restarting the slaves.
