Introduction: Principle and mechanism of master-slave replicationto implement replication, you must first open The binary log(bin-log) function on the Master side , otherwise it cannot be implemented. Because the entire replication process is actually a variety of operations that are logged in the execution log that Slave obtains the log from the Master side and

Two Linux servers with MySQL installed can be YUM installed, binary package installed, or source code package compiled. Two Linux servers with MySQL installed can be YUM installed, binary package installed, or source code package compiled.

Mysql master-slave configuration, mysql master-slave Configuration There can be many slave databases. We assume one master M and one slave S. Add the master M configuration file: Server-id = 1 Bin-log = logbin This name is random Remember to restart Add from S configuration file: Server-id = 2 The configuration file

Using Keepalived to build master-master MySQL Replication Overview: MySQL-HA has many implementation solutions. It is common to use master + keepalived to implement MySQL-HA. The two MySQL instances have a master-slave relationship and use Keepalived to configure virtual IP addresses, when one of the MySQL Databases go

Sometimes, the hacker Trojan Horse will host some processes in the system, and some anti-virus software because can not actively shut down these processes for cleaning, will require users to restart the computer after the antivirus (that is, can not carry poison antivirus), in this case, users can also pass the Wopti The process management maste
