How to configure the replication of mysql masters

In this article we will explore how to configure the replication of mysql masters. This process involves cluster settings with several server and MySQL database. You must know the database status on server 1 before starting the replication process. To ensure that the replication process is functioning correctly, you must ensure that server A is a master. This process can fail because of the configuration file bug, so make sure you check the MySQL error log to identify the problem.

You can also use a master-slave configuration. However, you must know some problems related to master-slave settings. For example, if you use several servers to Master-Master MySQL Replication the scale of your MySQL environment, you may experience results outside of synchronization because the two examples that send the same queries. For this case, you must use the same manual for all examples, instead of creating a separate database for each slave.

The main problem with this setting is that each server requires a unique index to track data in two different locations. This makes it difficult to make a replication scenario. In addition, the replication of complicated masters, and the process of spreading is long and boring. It's better to use multi-master replication if the data is very sensitive. If you need your MySQL cluster scale to several masters, make sure each server has a unique index.

You can configure the replication of mysql masters to use several servers with different roles. Master server can also be used as a backup server. This has many advantages. In addition to providing redundancy, this also makes it possible to increase speed, and can be used in scenarios where one server drops. In addition, you only need a few VPS servers. To balance the load, you can also set the haproxy server.

In multi-hosting scenarios, replication of mysql masters can be a challenge. This is because the server must continue to be monitored for problems and errors. A high failure rate also makes multi-hosting replication more challenging. Therefore, Digitaloceans provide special care for replication of mysql masters. This will make the master-master server more reliable than the others. The master-master database will be available for reading and written from both servers.

You can choose between using the original MySQL or Tungsten for replication of mysql masters. If you have an odd number of clusters, you can choose configurations with two masters. In this case, the index and cache will not be updated. In addition, you must realize that one of your groups cannot have more than nine nine nodes. If your master fails, replication will still function if you have enough master.

However, you must remember to be careful with active/passive replication. A masterpiece who down prevents replication from propagating to his slave. In addition, this type of replication is not recommended for all environments. In fact, it can cause conflicting changes. Active master may also be an obstacle when it cannot handle the workload of other masters. This is the reason why you should consider this option carefully if you use several MySQL servers.
