MySQL primary master replication +lvs+keepalived for MySQL high availabilityMySQL replication can ensure the redundancy of the data and read and write separation to share the system pressure, if the primary master replication can also be good to avoid the primary node single

sides, resulting in master-slave Replication failure. For example, if you copy an ID of 100 to the slave end on the master end, And the slave end already has the ID = 100 record for some reason, during the INSERT operation, the primary key will be repeated and insertion will fail. Skip this error. The method is as follows: 1: Stop the SLAVE Service Mysql> stop slave; 2: set the number of skipped events

interfering with the primary server. The primary server can continue processing updates during the backup process. MySQL uses 3 threads to perform replication functions (of which 1 are on the primary server and two on the server). When the start slave is issued, an I/O thread is created from the server to connect to the primary server and have the primary serve

-slave synchronization, which can be summarized as follows: 1. On the primary server, you must turn on the binary logging mechanism and configure a separate ID 2. On each slave server, configure a unique ID to create an account that specifically replicates the primary server data 3. Log the location information of the binaries on the primary server before starting the replication process 4. If you already have data in the database before you

master to its own trunk logs. First, slave starts a worker thread--i/o thread. The I/O thread opens a normal connection on master and then starts Binlog dump process. Binlog dump process reads the event from the binary log of master, and if it has been followed by master, it sleeps and waits for master to produce a new event. The I/O thread writes these events to the relay log. The SQL slave thread (SQL slave thread) handles the last step of the process. The SQL thread reads events from the log

-slave replication? 1. The master server/slave server settings increase robustness. When the master server encounters a problem, you can switch to the slave server as a backup. 2. By splitting the customer query load between the master server and slave server, a better customer response time can be obtained. But do not perform updates on the Master/Slave servers at the same time, which may cause conflicts. 3. Another advantage of using
