What is the method for configuring MySQL dual-machine hot backup?
In MySQL high availability setup, Master-Slave Replication is commonly used for data backup and fault recovery. Below are the methods to achieve MySQL high availability setup.
- Firstly, the binary logging feature needs to be enabled on the master server to record all data change operations.
- Create a user on the master server for replication purposes and grant them REPLICATION SLAVE permission.
- Configure master-slave replication parameters on the master server, including the ID of the master server, the name and location of the binary log file, etc.
- When configuring the master-slave replication parameters on the slave server, specify the IP address and port number of the master server, as well as the username and password of the replication user.
- Start the replication process from the server to synchronize the data from the master server to the slave server.
- Regularly check the replication status between the master and slave servers to ensure data synchronization is functioning properly.
- In the event of a main server failure, a quick switch to the backup server can be made to facilitate fault switching and data recovery.
Configuring dual-machine hot standby through the above steps ensures the high availability and data security of the database, while also increasing the stability and reliability of the system.
