What is the method for deploying MySQL read-write separation?

There are several methods to deploy MySQL read-write separation:

1. Employing MySQL Proxy allows for load balancing and failover of requests. It is a middleware that distributes read requests among multiple MySQL servers and directs write requests to the master server. Configuring MySQL Proxy enables read-write separation.
2. Utilize MySQL Group Replication: MySQL Group Replication is an official high availability solution introduced by MySQL, which implements master-slave replication and failover using group replication. It allows sending write requests to the primary server and read requests to multiple secondary servers.
3. Utilize MySQL master-slave replication: By setting up MySQL master-slave replication, direct write requests to the master server, and redirect read requests to multiple slave servers. Tools like MySQL Replication or Maatkit can be used for configuration and management.
4. By utilizing third-party proxy software such as MaxScale or HAProxy, you can configure load balancing and failover strategies to distribute read requests among multiple slave servers and direct write requests to the master server.

Regardless of the method used, the configuration file of MySQL needs to be modified and adjusted accordingly in order to achieve the effect of read-write separation. Different methods are suitable for different scenarios, so it is necessary to choose the appropriate solution based on specific requirements.
