Open the configuration manager for the MySQL node in the appropriate environment.Ģ. Now it’s time to start setting up the second DB server (the one that belongs to the master-mysql-2 environment).ġ. If an error occurs during this stage, repeat the procedure again or contact your Technical Support. In order to check MySQL was restarted successfully, you can navigate to the automatically opened actions tab. Once you’ve finished modifying the /etc/my.cnf file, just click Save and restart MySQL node in the master-mysql-1 environment as shown below.Ĥ. We suggest that you set auto_increment_offset option value to the same as the server-id parameter’s one, to avoid replication conflicts.ģ. In this article, we set the 1 value for the master-mysql-1 server and 2 for the master-mysql-2.īoth auto_increment_increment and auto_increment_offset options are intended for use with master-to-master replication and should be set according to your application requirements. auto_increment_offset = 1 - in the context of the multi-master replication can be used to avoid replication conflicts.auto_increment_increment = 1 - used to control the interval between successive column values.Once you are done you need to add the lines below in the my.cnf file. I have done selective where I select few DBs to Replicate. Next Select Configure as Master You can configure Replication as ALL or Selective. The option value, if given, is the basename for the log sequence. Mysql Replication With Phpmyadmin First Lets go to Replication panel on XAMPP. log-bin = /var/log/mysql/mysql-bin.log - defines whether the binary log is enabled or not.Once you are comfortable with the Multi-Master Replication you can include your own databases. Note: that these databases must not have been created yet. bin-log-do-db = example and bin-log-do-db = teste - tells the server to restrict binary logging to updates for the specified databases.server-id - common option which is used by replication servers for identifying themselves.Let’s consider in detail what exactly we are configuring with these options: Server-id = 1 binlog-do-db = example binlog-do-db = teste log-bin = /var/log/mysql/mysql-bin.log auto_increment_increment = 1 auto_increment_offset = 1 Regardless, the references in the article should only be used for replicating MySQL servers running on this platform. For example, instead of running PHP you may want to run a Java or Ruby application. Keep in mind that versions and environments' configuration may vary according to your needs and will also depend on your hosting provider configuration. Or, you can just clone the first environment, specifying the proper name in the corresponding frame:ģ. To create the second environment ( master-mysql-2) you will be required to repeat the steps of master-mysql-1 environment creation. Set up the cloudlet limits for each container. With the help of the opened topology wizard, set up the following environments:Īdd Apache application server with PHP support and MySQL database. After your dashboard is opened, click on Create Environment in the top panel.Ģ. Let’s create two environments with MySQL instances.ġ. The first thing that you need in order to configure a database replication is, at least, two db servers. So let’s get started! Create Environments The process is rather simple, but requires you to pay attention to some important details. Information on how to configure a master-slave replication for your MySQL database can be found here.Īnd in this tutorial we are going to explain how to configure the master-master (multi-master) replication in MySQL, specifically to be applied on environments. The platform lets you easily set up two different types of database replication - primary-secondary and primary-primary - in order to solve a number of different problems with performance, to support database backups, to alleviate system failures and much more.
