![]() Use the following command to list all of the databases. Now go to the slave server and log in to the MySQL database server once more. To do so, go to the master server and connect to the MySQL database server. Now that you’ve completed the configuration of both the master and slave servers, it’s time to check to see if the configuration is correct and if replication is possible. Mysql> START SLAVE Put MySQL Master-Slave Replication to the Test Finally, run the command below to start the slave threads: Use the file name and position that you received from the master server as well. Run the following query to set up the slave server to replicate from the master server.Ĭheck that you’re using the right IP username and password. Then, stop the replication thread and connect to the MySQL server. The slave server must now be configured to replicate from the master server. You should make the following changes to the mysql slave configuration file, just as you did when setting up the master: Keep track of the generated filename msql-bin.000001 and its location 683. You will now type the following command, which will print the binary filename and position. ![]() Keep in mind to utilize your machine’s IP address. Run the following commands to create the replica user while also providing the user slave access. As a result, log in as the root user to your MySQL master server and enter the password. Once the MySQL installation process is completed, run the following command to open the MySQL configuration file: vim /etc/my.cnfĪdd the lines mentioned below to the “mysqld” section. The most recent version of MySQL 8.x is already included in RHEL 8’s default repository, and you may install it using the following yum command: yum install -y mysql_secure_installation In this configuration, we’ll have two RHEL 8 servers with the following IP addresses: Steps to Achieve MySQL Master-Slave Replication Analytics and Benchmarking: Database analysts can use this approach to execute various data analysis tests and experiments on slaves without disrupting the master.This enables apps to handle high numbers of reading and write operations with ease. Data corruption is reduced because the master server is fault-free and has a 99.9% uptime. Backup: In only a few minutes, you can duplicate the most recent database snapshot to another database and create a backup.However, read requests from websites can be split across numerous slaves to improve the website’s speed. These changes are spread and promoted by the master to the slave after they are made to the master database. Performance: The master database handles all database write operations.As a result, website administrators must give the ideal arrangement for the speedy loading of information on the site. Most web applications and sites you’ll come across nowadays have more read operations than writing activities to the database. Scalability: To lessen the load on the server and provide faster access, all database query requests can be sent to numerous database servers.It also has several other advantages, such as: One of the main advantages of a master-slave replication system is that it provides a standby system with a live backup that can be promoted to master status if the primary master server fails. The slaves can also be utilized to minimize the strain on the master database by providing data accessibility. Both the master and the slave perform the read operation. As a result, the write operation is limited to the master database. Data is initially saved in the master, then replicated to the slaves. It’s always a single or one-way data transmission in this operation. You can have one master and many slaves, or numerous masters and many slaves, and so on. There are different types of replication procedures in this replication. Your application will not experience any downtime because of the replication procedure. They can switch over the slave database and keep the application up and running in various scenarios when the is down due to any difficulties. This allows the database administrator to create a continuous live backup of the database. Database administrators can use the master-slave replication procedure to replicate or copy data from multiple servers at the same time. MySQL replication is a real-time mechanism that automatically copies or replicates data from one server to another backup server.
