MariaDB [(none)]> HELP RESET SLAVE;
Name: 'RESET SLAVE'
Description:
Syntax:
RESET SLAVE [ALL] RESET SLAVE makes the slave forget its replication position in the
master's binary log. This statement is meant to be used for a clean
start: It deletes the master.info and relay-log.info files, all the
relay log files, and starts a new relay log file. To use RESET SLAVE,
the slave replication threads must be stopped (use STOP SLAVE if
necessary). *Note*: All relay log files are deleted, even if they have not been
completely executed by the slave SQL thread. (This is a condition
likely to exist on a replication slave if you have issued a STOP SLAVE
statement or if the slave is highly loaded.) In MySQL 5.5 (unlike the case in MySQL 5.1 and earlier), RESET SLAVE
does not change any replication connection parameters such as master
host, master port, master user, or master password, which are retained
in memory. This means that START SLAVE can be issued without requiring
a CHANGE MASTER TO statement following RESET SLAVE. In MySQL 5.5. and later, you can use RESET SLAVE ALL to reset these
connection parameters (Bug #). Connection parameters are also
reset if the slave mysqld is shut down. If the slave SQL thread was in the middle of replicating temporary
tables when it was stopped, and RESET SLAVE is issued, these replicated
temporary tables are deleted on the slave. URL: http://dev.mysql.com/doc/refman/5.5/en/reset-slave.html MariaDB [(none)]>
MariaDB [(none)]> RESET SLAVE; #它会自动删除master.info和relay-log.info文件，所有中继日志文件，并启动新的中继日志文件。
二.复制监控
1>.查看所有可用的二进制日志(要求数据库需要开启二进制日志功能)

注意观察上面的输出信息，尤其要观察下面的值是否为0,如果为0说明复制不存在延迟，若不为0说明从库数据和主库数据延迟情况，我建议大家生产环境中要监控该参数项。

四.如何确定主从节点数据是否一致
可用借助于第三方工具，比如:percona-tools
五.数据不一致如何修复
删除从数据库，重新复制
六.复制的问题和解决方案
1>.数据损坏或丢失
Master： MHA + semi repl
Slave： 重新复制
2>.混合使用存储引擎
MyISAM：不支持事务
InnoDB： 支持事务
3>.不惟一的server id
重新复制
4>.复制延迟
需要额外的监控工具的辅助
一从多主:mariadb10版后支持
多线程复制：对多个数据库复制
