database seems to be a bad idea for Debian-based system: check this comment for details.If you’re unsure about doing that, you might just choose to exclude that: the only thing you’ll be missing would be syncing your users automatically, which isn’t critical as long as you don’t do that opposed to creating a user here with what would be a conflicting username.This is, of course, one of the tradeoff decisions you'll need to make.So, we create triggers do accomplish the purpose of updating the distance server.They are written as triggers, with the idea being that we don't want to do something to ourselves that we can't do to the other server -- for example, if a username already exists on the other server, but not here, we want the insert on the other server to throw an error that prevents us from creating the user here...DELIMITER $$ CREATE TRIGGER user_bi BEFORE INSERT ON user FOR EACH ROW BEGIN INSERT INTO remote_user (username,password) VALUES (NEW.username, NEW.password); END $$ CREATE TRIGGER user_bu BEFORE UPDATE ON user FOR EACH ROW BEGIN UPDATE remote_user SET username = NEW.username, password = NEW.password WHERE username = OLD.username; END $$ CREATE TRIGGER user_bd BEFORE DELETE ON user FOR EACH ROW BEGIN DELETE FROM remote_user WHERE username = OLD.username; END $$ DELIMITER ; This is not a perfect solution and is not a high-availability solution, because it relies on solid connectivity between the two systems and even if you are using Inno DB and transactions, the actions you take against the target table are not part of your local transaction and cannot be rolled back.I use the engine quite a bit; it comes in handy for a number of creative purposes in my environment, including one situation where I used a federated query launched by a trigger to impose foreign key constraints against a foreign data source; however, I restrict its use to back-end processes where unexpected issues such as timeouts, coding errors, or server-to-server network/outage/isolation events cannot result in the end user on one of our web sites experiencing any kind of problem.

You might also want to keep out other databases such as mysql or other ones: if that’s the case, just add those you want to exclude by adding a binlog-ignore-db and replicate-ignore-db command for each one of them.In order to do that you’ll need a second machine/server, meaning you’ll have to sustain more costs: don’t make this stop you – an investment like that is hardly worthless: conversely, it will most likely be a substantial improvement for your system.That’s what you’ll basically gain: is when you have a 2 VPS (or hosting servers) environment/farm, each one providing an http web server (such as IIS or Apache) containing one or more web sites connected to a local My SQL server instance on the same machine.The next thing we need to to is to replicate all the commands received by Server A to Server B: in other words, we need to configure Server B as a slave of Server A.In order to do so, connect to Server A (via SQLyog, query browser or console) and type the following sql command: ------------------ ---------- -------------- ------------------ | File | Position | Binlog_Do_DB | Binlog_Ignore_DB | ------------------ ---------- -------------- ------------------ | mysql-bin.000001 | 107 | example | test, informatio | ------------------ ---------- -------------- ------------------ 1 row in set (0.00 sec) STOP SLAVE; CHANGE MASTER TO MASTER_HOST = 'Server A IP Address', MASTER_USER = 'replicator', MASTER_PASSWORD = '[replicator_password]', MASTER_LOG_FILE = 'mysql-bin.000001', MASTER_LOG_POS = 107; START SLAVE; Now you need to do the same thing from the other side.
