Copying an array refers to generating a new array with the same content as the original array. Array assignment is frequently used and important.There are two replication methods: shallow replication and deep replication. This concept is not unique to arrays. There are some differences between the replication mode and
Master-slave replication for mysql and master-slave replication for mysql Mysql master-master replication Summary I. Main Ideas of Mysql Master/Slave replication: 1. mysql replication essence: It is another MySQL database server that executes the binary log of this data chan
Analysis of MySQL replication and optimization principles and methods, mysql replication Optimization PrinciplesI. Introduction MySQL's built-in replication solution brings the following benefits: Data backup. Server Load balancer. Distributed Data. Concepts: Master: the database to be copied.

I. Principles of MySQL master-slave Replication 1. mysql replication process: each time a write operation is executed, it will save a copy to its own database. At the same time, this write operation will also be stored in a binary log file, and save them as events. Therefore, each write operation or modification operation on the front-end data in this database will save an event, we will send the event to a
First, IntroductionIn the master-slave copy of the previous article: http://www.cnblogs.com/lay2017/p/9043985.htmlWe learned that MySQL writes logs through master, slave reads and executes the log content to achieve slave data consistent with master. So based on this principle, we can realize the replication function of two master.Broadly as follows:1, both master open Log-bin write log2, ID to repeat3. Configure the tables to be copied4, two master r
Master-Slave replication principle MySQL replication is an asynchronous replication process that replicates from master to one or more slave. The entire replication process between master and slave is done primarily by three threads, one IO thread on the master side and two threads (SQL thread and IO threa
Brief introduction UNIX and Linux users typically check the processes running on their servers to perform problem analysis and to check the resources consumed in the server. This information is useful not only for administrators who perform issues and resource analysis, but also for those who develop high availability and failover scripts that monitor the DB2 process to determine when operations such as database restarts or server failover are require
