I read the Master-Slave settings of MySQL after work in the company. The general meaning and process have been understood, but I have never practiced it. I have time to practice it today. I have two Win7 servers on hand. Let's use them together !! First set the relationship A to Master, B to Slave. (The Mysql on both machines is 5.0, but different) set A's my. iniserver-id1log- I read the

There are two main mechanisms for Spark Master primary and standby switching, which are based on the file system and one based on the zookeeper. File system-based primary and standby switching mechanism needs to be manually switched to standby master after the active master is hung off. The primary and standby switching mechanism based on zookeeper can automatica

MYSQL supports unidirectional and asynchronous replication. one server acts as the master server during the replication process, and one or more other servers act as slave servers. The master server writes updates to the binary log file and maintains an index of the log file to track log loops. When a slave server connects to MYSQL supports unidirectional and asynchronous replication, one server acts as the
