How does mysql synchronize a table?
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
