mysql synchronous replication

In the mysql5.5/5.6 version, set up synchronous replication filtering, such as setting the T2 table that ignores the test library, you need to add in the my.cnf config file:Replicate-ignore-table=test.t2The MySQL service process must be restarted to take effect.In MySQL5.7, a new command is available to support online dynamic modification without restarting the

MySQLTo create a Slave user:Create user ' slave ' @10.0.0.3 identified by ' slave ';Grant Replication Slave on * * to [e-mail protected] identified by ' salve ';Flush tables with read lock; Execute the following command to lock the database to prevent writing dataDo not close the current window, open a new window:Mysqldump-uroot-p--all-databases>all.sqlMysql-uroot-pShow master status; rememberMysql> Show master status;+------------------+----------+-

The function of two database synchronization, master-slave mode and mutual backup mode can be realized by this feature. The settings for database synchronization

Knowledge background??I. MARIADB copy-related knowledge??Source of 1.mariadb???? MySQL database is currently in the database market share only second only to the Oracle database, but also the open source database leader. Because MySQL database is open-source and high-performance, but also free (but not optimistic after Oracle acquisition), so the father of MySQL

two replication schemes: First, both statement-based replication and row-based replication are performed asynchronously by recording the binary logs of the master server and performing replay on the slave server. Mariadb or mysql replication is mostly backward compatible. T

IntroducedOne important feature of Meta compared to Kafka is the implementation of the message high availability scenario, which we call the HA scenario. The message is written to the disk immediately after it is sent to the broker and returned to the client to tell the producer that the message was sent successfully, and the control of the unflushThreshold unflushInterval two parameters can guarantee the security of the stand-alone message data, as long as the machine's disk is not permanently

So far, we have processed file-based replication (or log shipping) and simple stream-based replication settings. In both cases, after the transaction is committed on master, the data is submitted and received by slave. It will still be lost at the time that master commits and slave actually receives the data completely.In this chapter, we will study the following topics:• Ensure that no transactions are los

Concepts ORACLE ORACLE is a large-scale relational database based on advanced Structured Query Language (SQL). It is a set of regular data manipulation in a language that facilitates logical management. It is one of the databases in the CLIENT/SERVER architecture. Advanced Replication What is replication? Simply put, replication is the process of copying data in
