Last week in the production environment encountered a problem, do not dare to enjoy, take out to the small partners to do a simple share. Cause: Due to the IDC room power failure (it is estimated where the excavator touched the next bar), causing all the server restart, affecting the MySQL database.

Recently, the team has a Data Synchronization requirement. Generally, two or more database (MariaDB) servers use the VPN channel to synchronize data with one database. First, they do not care about the VPN channel communication problem, this kind of multi-master and One-Slave Data Synchronization requirement has also been achieved through the replication function

, can choose strong consistency model. principle Brief: Redis Master-slave replication can be divided into full-volume synchronization and incremental synchronization based on whether it is full. Full-Volume synchronization: Redis full replication typically occurs during the slave initialization phase, when slave needs to copy all the data on
