This article is about how to configure double master in mysql. The editor thinks it is very practical, so share it with you as a reference and follow the editor to have a look.

Double master configuration of mysql

Suppose the ip of the two machines is machine one: 192.168.14.37, machine two: 192.168.14.38, and the server is linux Rhel 5.9.

Execute the create user statement on both servers:

Mysql: > create user 'repl'@'%' identified by' 135246password;-- create user repl password 135246

The server executes:

Mysql: > grant replication client,replication slave on *. * to 'repl'@'192.168.14.38' identified by' 135246 server;-- authorized server one can access server two remotely

Server 2 executes:

Mysql: > grant replication client,replication slave on *. * to 'repl'@'192.168.14.37' identified by' 135246 server;-- license server 2 can access server 1 remotely

Verify (enter the password when prompted):

Connect server two on server one

Mysql-h 192.168.14.38-u repl-p

Connect server one on server two

Mysql-h 192.168.14.37-u repl-p

View mysql:

First: vi / etc/my.cnf

On server 1, add the following:

[client] default-character-set=utf8 [mysql] default-character-set= UTF8 [mysqld] server_id = 1log-bincharacter-set-server=utf8# table name is case-insensitive lower_case_table_names=1#server_id = slave uniquely identify is 2show master status

You can get the MASTER_LOG_FILE and MASTER_LOG_POS information of server one and server two.

Suppose the first server is "localhost-bin.000004" and the second is "localhost-bin.000005" and "667"

Execute on server one:

Stop slave;CHANGE MASTER TO MASTER_HOST = '192.168.14.38, MASTER_USER =' repl', MASTER_PASSWORD = '135246, MASTER_LOG_FILE =' localhost-bin.000004', MASTER_LOG_POS = 120; start slave

Execute on server 2:

Stop slave;CHANGE MASTER TO MASTER_HOST = '192.168.14.37, MASTER_USER =' repl', MASTER_PASSWORD = '135246, MASTER_LOG_FILE =' localhost-bin.000005', MASTER_LOG_POS = 667; start slave

Finally, verify whether the primary primary synchronization is successful:

Add table example to server-mysql

Mysql: > create database example1; use example1;create table example1 (length int)

Finally, check server 2 to see if there is this database, this table, and this piece of data.

View synchronization status: show slave status\ G

If something goes wrong, you can see the error log.

Error leads to synchronization failure refer to mysql slave-skip-errors=all for in-depth understanding

Note: the two servers will not synchronize the data before setting double master.
