mariadb replication

MARIADB, as a branch of MySQL, is already widely used in open source projects, such as hot OpenStack, so the cluster deployment is essential to ensure high availability of the service while increasing the load capacity of the system.MariaDB Galera Cluster IntroductionThe MARIADB cluster is a MARIADB synchronous multi-host cluster. It only supports the XTRADB/INNO

1.MySQL High-availability backgroundsThe master-slave replication of a database is a useful feature, but it is difficult to ensure its high availability. Implements MySQL master-slave replication high-availability tools, common are: (1). MMM: Eliminated, there are some problems in consistency and high concurrency stability. (2). MHA: Some people still use, but there are some problems, but also

Centos7: The correct command for installing mariadb, centos7mariadb The centos7 System of linode is used, and mariadb is used by default when mysql is installed. However, no matter whether you use the linode official website instructions or the basic installation method found by Baidu, the installation fails. Always prompt this sentence: ERROR 2002 (HY000): Can't connect to local MySQL server through socket

I have been using mariadb for a while. The common commands and syntaxes have not changed. A little more complex, such as replication, does not find any difference in root mysql.However, there are actually some differences today. mariadb's permission management root mysql is different. mysql can create an account with the same root account permissions, but

Then create a copy user to take effect. (If you are running on two different computers, you can not delete these two lines .) $ bin/mysql -S /tmp/mysql1.sock -urootMariaDB [(none)]> use mysql;MariaDB [m

The so-called "copying objects" generates a "sibling brother" that is exactly the same as the specified object ". For object replication, there are two scenarios: shallow replication and deep replication. 1. Shallow copy: when the field value of the object is copied, the object referenced by the field will not be copied. For example, if an object has a fiel

Install MariaDB and MySQL MariaDB can be used to replace enhanced MySQL versions, but MariaDB can also be installed when MySQL is installed. (This makes sense. For example, you want to migrate data from one database/application to another database/application .) The following describes how to install MariaDB when MySQL

This article demonstrates how to build the most basic transactional replication.Environment Preparation: 2 virtual machines:The server names are Repa and Repb,repa are publishers, and REPB are subscribers. Are installed WindowsServer 2008r2 English version (the reason for working in a foreign company). and ensure that the two servers can exchange visits.SQL Server:In the above virtual machine, install SQL Server R2 x64 English Enterprise Edition separately.Demo Database:Microsoft Sample Database

Mariadb/mysql built-in replication capabilities are the foundation for building large, high-performance applications. The distribution of MySQL data across multiple systems is done by copying data from one of the MySQL hosts (master) to the other host (slaves) and performing it again. One server acts as the primary server during replication, while one or more oth

The ultimate goal of data replication is to synchronize the data of one server with the data of another server, which can achieve data redundancy or load balancing of services. A master server can connect multiple slave servers, and the slave server can act as the master server in turn. The master-slave server can be located in different network topologies. Due to the powerful mysql replication function, th

The previous blog said how to use Xtrabackup to back up and restore databases. After the database has been restored, the two machine databases are the same, including Binlog file and Pos.At the same time, after the Xtrabackup backup is completed, the relevant Binlog file and POS information has been written to the backup information file, and the cat can view it under Linux. Then execute the Change Master command on the standby to successfully build the master-slave
