MySQL implementation, one master multi-slave + Cascade synchronization + Bidirectional Synchronization

Experiment:

A master more from

3307 Configuration:

[Mysqld]

Log-slave-updates # the middle need to open this .

Log-bin =/data/3307/mysql-bin

expire_logs_days = 7 #binlog How many days are saved find–mtime +7

Prevents writes from the library from being written to ignore synchronous db. Or reclaim permissions from the Vault:

[Mysqld]

Slave-skip-errors = 1032,1062

replicate-ignore-db = MySQL

binlog-ignore-db = MySQL

Binlog-ignore-db = Information_schema

Binlog-ignore-db = Performance_schema

Bidirectional synchronization

3306

[Mysqld]

Log-bin =/data/3306/mysql-bin

Log-slave-updates

3307

[Mysqld]

Log-bin =/data/3308/mysql-bin

Log-slave-updates
