3台机器mysql数据同步失败

liyihongcug · 发表于 2009-6-25 20:15:35

已经成功2台mysql 复制（双向同步）。现在马上搞3台机器
基本想法如下
a （2个库ccxyaccount,ccxydb）
b（1个库  ccxyaccount）
c  （1个库 ccxydb）
为了简化难度，现在仅仅要求a b之间数据同步，  c只要求实实时去取a更新的数据就可以拉
a的my.cnf如下（现在质疑复制是否支持多个库的数据同步）
[mysqld]
datadir=/var/lib/mysql
socket=/var/lib/mysql/mysql.sock
user=mysql
# Default to using old password format for compatibility with mysql 3.x
# clients (those using the mysqlclient10 compatibility package).
old_passwords=1
log_bin = /var/log/mysql/log_bin
server-id=1
#sql-bin-update-same
binlog-do-db = ccxyaccount,ccxydb
#binlog-ignore-db = mysql,test

master-host = 10.0.4.150
master-user = back
master-password = back
master-port = 3306
replicate-ignore-db=mysql,test
replicate-do-db=ccxyaccount

[mysqld_safe]
log-error=/var/log/mysqld.log
pid-file=/var/run/mysqld/mysqld.pid

b c 类似。
于以前的问题不同，现在没有报错（有一定经验）。
slave stop;
change master....;
slave start;
3台机器同时ok的，没有错误。

可惜测试数据的时候发现，3台机器之间完全没有数据同步，甚至局部a b 之间数据也没有任何联系。
问1现在质疑复制是否支持多个库的数据同步
2 如何查找问题在哪里？

支持
看日志及 mysql>show slave status\G

什么日志日志文件名以及他的路径
mysql>show slave status\G 都很正常

liyihongcug · 发表于 2009-6-26 13:04:31

a 主库从（2个库ccxyaccount,ccxydb）
b 从主（1个库  ccxyaccount）
c  从（1个库 ccxydb）

也就是说a  b 是数据同步的ccxyaccount c 仅仅复制来自a的一个库ccxydb
a 分别有2个复制用户分别 back （对应 b机器） back2（都应c机器）
。这样楼上应该清楚业务了吧。
