MySQL master-slave copy structure is based on MySQL Bin-log log, from the library through open IO process received the main library Bin-log log increment Information and save it to the local relay log, and then translate the incremental information obtained from the relay log into SQL by opening the MySQL process After the sentence is written to from the database. The master-slave replication structure can actually implement two functions: 1. A da

It is extremely important to record this scheme, usually in the form of a service level agreemenet ). The service level agreement is related to backup and recovery in three aspects: Mean Time (mean time Betwwen failures, MTBF)
