![]() Understanding Replication in MariaDB Image Source Here’s another blog piece that sheds light on the different types of data replication. Upon subsequent connection, the updated data will get merged with the master. Distribution of Data: With replication in place, you can work locally on this data without connecting to the master server.Data Analysis: Data can be analyzed on the slave server without adding extra load to the master server with replication in place.This backup can then act as a stand-alone server in a stable state. Backup Assistance: This involves replicating data to a slave that you can use as backup data.Scalability: Having one or more slave servers allows data reads to be done on them, thereby reducing the load on the master server, which only allows performing the write operation. ![]() In the master-slave configuration, any changes that are made to one of the slaves, automatically reflect in the master record in a matter of seconds, following which, all the slaves receive the data updations from the master server in a fully-automated manner. Replicated data can be a complete set of databases, a single database, or even data tables taken from the desired database. The master server is known as such because it provides the data for replication. What is Data Replication?ĭata replication is a process of copying data from various databases, known as master databases or servers to multiple slave servers. Some of its notable users include Wikipedia,, Google, etc.įor further information on MariaDB, you can check the official website here. ![]() It is fast, scalable, robust, and contains various plug-ins. It transforms data into a structured and organized form and provides support for a variety of applications. The original developers of MySQL designed MariaDB as an alternative to the MySQL database after concerns over the acquisition of MySQL by Oracle Corporations in 2009. MariaDB is one of the most popular open-source relational database management system (RDBMS). The present article aims at providing a step-by-step guide to help you set up MariaDB master-slave replication with ease. Method 2: MariaDB Replication Using Hevo.Method 1: MariaDB Replication Using the Master-Slave Approach.Methods to Set Up the MariaDB Replication.I should also add that this database that supposedly has missing tables is working perfectly on the master for an active website.Īny help to point me in the right direction would be appreciated. Seconds_Behind_Master (blank but would like this setup) Query: 'DELETE FROM *tablename* WHERE expires Last_Error Error 'Table '*databasename*.*tablename*' doesn't exist' on query. ![]() Relay_Log_File *servername*-relay-bin.000003 Slave_IO_State Waiting for master to send event Below is the table i copied from phpMyAdmin. Now I'm not sure if I am supposed to completely import the databases from my master manually, and then it updates it or whatever (again no clear tutorials are out there for windows). I have both servers online and they can see each other and are connected to each other, however when it comes to syncing under the Slave Status table in phpMyAdmin I am constantly getting errors saying tables don't exist. One Master, and One Slave (setup through phpMyAdmin) ![]() First of all let me say there are no CLEAR tutorials for how to do this on windows, I'm a programmer and have been using MySQL and PHP for years, and have never seen so many different answers when it comes to linux, and absolutely nothing for windows users.Īnyway I have been working for 2 weeks trying to solve this myself, and I am at the same place no matter what tutorial, method or whatever I try. ![]()
