标题: 【讨论中】环状SQL同步问题
本帖最后由 chinafenghao 于 2013-10-11 12:32 编辑

有三台服务器A B C，需要配置为：B主A从、C主B从、A主C从，组成环状，当修改ABC中任意一台的数据库时其他两台同步，但是当我配置完后发现，在其中一台的数据库中增加一个表时，只有一台同步，另一台没有反应，比如在A添加表时，B没有反应，C同步成功，但是show slave status\G显示的状态都正常，原因找了一下午也没找出来，求大神解惑！谢谢！

ABC中my.cnf文件（只贴了A的，除了severid不一样其他的都一样）：
[mysqld]
datadir=/var/lib/mysql
socket=/var/lib/mysql/mysql.sock
user=mysql
# Disabling symbolic-links is recommended to prevent assorted security risks
symbolic-links=0
server-id=1
replicate-do-db=test
log-bin=log-slave-updates
log-slave-updates = on
binlog-ignore-db=mysql
auto_increment_offset = 1
auto_increment_increment = 2
relay-log=relay-bin

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

没做过闭环的,不清楚原因。

回复 2# chinafenghao

终于搞明白了，配置文件中log-slave-updates = on应该写为log-slave-updates
