mysql主从同步错误解决和Slave_IO_Running: NO
一：
Slave I/O: error connecting to master ‘backup@192.168.1.x:3306‘ - retry-time: 60 retries: 86400, Error_code: 1045
解决方法
从服务器上删除掉所有的二进制日志文件，包括一个数据目录下的master.info文件和hostname-relay-bin开头的文件。
master.info:：记录了Mysql主服务器上的日志文件和记录位置、连接的密码。
或者是防火墙问题
二：出现错误提示
Error reading packet from server: File ‘/home/mysql/mysqlLog/log.000001‘ not found (Errcode: 2) ( server_errno=29)
解决方法：
由于主服务器运行了一段时间，产生了二进制文件，而slave是从log.000001开始读取的，删除主机二进制文件，包括log.index文件。
三：错误提示如下
Slave SQL: Error ‘Table ‘xxxx‘ doesn‘t exist‘ on query. Default database: ‘t591‘. Query: ‘INSERT INTO `xxxx`(type,post_id,browsenum)
SELECT type,post_id,browsenum FROM xxxx WHERE hitdate=‘20090209‘‘, Error_code: 1146
解决方法：
由于slave没有此table表，添加这个表，使用slave start 就可以继续同步。
四：错误提示如下
Error ‘Duplicate entry ‘1‘ for key 1‘ on query. Default database: ‘movivi1‘. Query: ‘INSERT INTO `v1vid0_user_samename`
VALUES(null,1,‘123‘,‘11‘,‘4545‘,‘123‘)‘
Error ‘You have an error in your SQL syntax; check the manual that corresponds to your MySQL server version for the right syntax
to use near ‘ ‘ at line 1‘ on query. Default database: ‘club‘. Query: ‘INSERT INTO club.point_process ( GIVEID, GETID, POINT, CREATETIME, DEMO )
VALUES ( 0, 4971112, 5, ‘2010-12-19 16:29:28‘, ‘
1 row in set (0.00 sec)
Mysql > Slave status\G;
显示：Slave_SQL_Running 为 NO
解决方法：
Mysql > stop slave;
Mysql > set global sql_slave_skip_counter =1 ;
Mysql > start slave;
五：错误提示如下
show slave status\G;

Last_Errno: 1594
Last_Error: Relay log read failure: Could not parse relay log event entry. The possible reasons are:
the master‘s binary log is corrupted (you can check this by running ‘mysqlbinlog‘ on the binary log),
the slave‘s relay log is corrupted (you can check this by running ‘mysqlbinlog‘ on the relay log),
a network problem, or a bug in the master‘s or slave‘s MySQL code. If you want to check the master‘s
binary log or slave‘s relay log, you will be able to know their names by issuing ‘SHOW SLAVE STATUS‘ on this slave.
Skip_Counter: 0
Exec_Master_Log_Pos: 1010663436
这个问题原因是，主数据库突然停止或问题终止，更改了mysql-bin.xxx日志，slave服务器找不到这个文件，需要找到同步的点和日志文件，然后chage master即可。
解决方法：
change master to
master_host=‘IP‘,
master_user=‘同步帐号‘,
master_password=‘同步密码‘,
master_port=3306,
master_log_file=‘mysql-bin.000025‘,
master_log_pos=1010663436;
六：错误提示如下
Error ‘Unknown column ‘qdir‘ in ‘field list‘‘ on query. Default database: ‘club‘. Query: ‘insert into club.question_del (id, pid,
ques_name, givepoint, title, subject, subject_pid, createtime, approve, did, status, intime, order_d, endtime,banzhu_uid,
banzhu_uname,del_cause,qdir) select id, pid, ques_name, givepoint, title, subject, subject_pid, createtime, approve, did,
status, intime, order_d, endtime,‘1521859‘,‘admin0523‘,‘无意义回复‘,qdir from club.question where id=7330212‘
1 row in set (0.00 sec)
这个错误就说club.question_del 表里面没有qdir这个字段 造成的加上就可以了~！
在主的mysql ： 里面查询 Desc club.question_del；
在 错误的从服务器上执行 ： alter table question_del add qdir varchar(30) not null;
七:错误提示如下
Slave_IO_Running: NO
这个错误就是IO 进程没连接上 ，想办法连接上把 把与主的POS 号和文件一定要对，然后重新加载下数据。具体步骤：
slave stop;
change master to master_host=‘IP地址‘,master_user=‘club‘,master_password=‘mima ‘,master_log_file=‘mysqld-bin.000048‘,MASTER_LOG_POS=396549485;
注：master_log_file=‘mysqld-bin.000048‘,MASTER_LOG_POS=396549485;是从主的上面查出 来的 ：show master status\G;
LOAD DATA FROM MASTER;
load data from master；
slave start;
八 ,mysql报错如下：
mysql> show slave status\G;

mysql>
解释：
show slave status\G
\G就是结束 再加一个";" 就多余了，所以才报错，这2个结束符号别重复使用就是...

解决方法是在master端从新看一下master状态
在master那边，执行：
flush logs;
show master status;
记下File, Position。
在slave端，执行：
Slave stop
CHANGE MASTER TO MASTER_LOG_FILE=‘testdbbinlog.000008‘,MASTER_LOG_POS=107;
slave start;
show slave status \G
一切正常。
