MySQL 复制不工作主从

Question

我是 MySQL 新手，尝试创建复制这是Master上的my.cnf

[mysqld]
datadir=/var/lib/mysql
socket=/var/lib/mysql/mysql.sock
user=mysql

log-bin = /var/lib/mysql/logs/mysql-bin.log
binlog-do-db=fedorareptest1
server-id=1
----

从机上的 My.cnf

[mysqld]
datadir=/var/lib/mysql
socket=/var/lib/mysql/mysql.sock
user=mysql

server-id=2
master-host=130.14.165.25
master-connect-retry=60
master-user=reptest
master-password=nopass!123
replicate-do-db=fedorareptest1
relay-log = /var/lib/mysql/logs/slave-relay.log
relay-log-index = /var/lib/mysql/logs/slave-relay-log.index

--------

注意:“replicate-do-db=fedorareptest1”中提到的数据库是master上的数据库。从站上的这个数据库名称是 fedoratest2。我应该在上面使用它还是应该在 master 上使用它

当我做从状态时:

当我对表进行更新时，该行不会显示在从站上!

请帮助，我是 MYSQL 的新手。

你应该避免使用 *do-db 选项，因为它们可以 cause problems

检查查询是否通过了您的奴隶:

mysqlbinlog --short-form /path/to/relaylogfile | less

.. 或..

tcpdump -vv -A -i lo0 tcp port 3306 | tee dump.log

更新 重读您的帖子后我注意到了这个问题:您更改了数据库名称但未使用 replicate-rewrite-db
