In a MySQL dual-machine hot backup architecture, the method for recovering from a failure typically includes the following steps:<\/p>\n

    \n
  1. Troubleshooting: Identify whether the main database or backup database has experienced a failure through monitoring systems or manual checks.<\/li>\n
  2. Switching primary and backup: If the primary database fails, the backup database needs to be switched to become the primary database and take over the service. This can typically be achieved through manual or automatic switching methods.<\/li>\n
  3. Data recovery: In the event of a failure of the primary database, it is necessary to synchronize the data from the backup database to the primary database to ensure data consistency. This can be achieved through MySQL’s replication feature or other data synchronization tools.<\/li>\n
  4. Fix the problem: Repair the malfunction of the main database to ensure it resumes normal operation. Data recovery, hardware repair, and other necessary operations can be carried out based on the specific situation.<\/li>\n
  5. Restore service: Ensure that after the main database is restored to normal operation, access to the applications is also restored to ensure smooth service operation.<\/li>\n<\/ol>\n

    By following the steps above, we can achieve fault tolerance in the MySQL dual-hot standby architecture, ensuring the safety of data and the continuity of services.<\/p>\n","protected":false},"excerpt":{"rendered":"
