This article mainly explains "mysql how to synchronize a table," interested friends may wish to have a look. The method introduced in this paper is simple, fast and practical. Let's let Xiaobian take you to learn "mysql how to synchronize a table"!

1. The Lord modified my.cnf file: (Lord)

server-id=1?

log-bin=mysql-bin

2. Modify profile my.cnf from above (from above)

server-id=2

relay-log=replay-bin

read-only =1

replicate-ignore-db = mysql

replicate-ignore-db = test

replicate-ignore-db = information_schema

replicate-wild-do-table = gutest.a

3. User creating synchronization (master)

GRANT REPLICATION SLAVE, REPLICATION CLIENT ON *.* to rep@'192.168.1.196' identified by 'rep';

4. In the main query the Lord's log information (Lord)

flush tables with read lock;

show master status;

unlock tables;

5. Sync to Master Library (from top)

stop slave;

reset slave;

CHANGE MASTER TO MASTER_HOST ='192.168.1.195', MASTER_USER ='rep ',MASTER_PASSWORD ='rep',MASTER_LOG_FILE ='mysql-bin. 00001', MASTER_LOG_POS=986; #986 is the log number queried from the previous statement

start slave;

6. Verify from above:

mysql> show slave status\G
