mysql5 master slave安装配置日志
2007-11-11 16:27:07 来源:WEB开发网背景:
master:192.168.100.231 MySQL(和PHP搭配之最佳组合)5.0.19 linux
slave: 192.168.100.234 MySQL(和PHP搭配之最佳组合)5.0.18 linux
step1) 配置master
在/etc/init.d MySQL(和PHP搭配之最佳组合)d段加入
#(要同步的数据库)
binlog_do_db = test
并确保
server-id=1
log-bin=MySQL(和PHP搭配之最佳组合)-bin
step2) 授权slave
GRANT REPLICATION SLAVE ON *.* TO test@192.168.100.234 IDENTIFIED BY '123';
重启master
step3)配置slave
vi /etc/my.cnf
设置下面4行
server-id = 2
master-host = 192.168.100.231
master-user = test
master-password = 123
重启发现slave的I/O线程工作正常,而SQL线程不工作
报了很怪的错误
070307 16:30:27 [ERROR] Slave: Error 'Table 'passport.loginuser' doesn't exist' on query. Default database: 'passport'. Query: 'delete from loginuser where tokenRefreshTime<='2006-07-03 07:00:00'', Error_code: 1146
070307 16:30:27 [ERROR] Error running query, slave SQL thread aborted. Fix the problem, and restart the slave SQL thread with "SLAVE START". We stopped at log 'MySQL(和PHP搭配之最佳组合)-bin.000001' position 98
因该是relay log中的数据有问题,于是在
将master机器上的数据拷到244,发现还是有问题。
于是在/etc/my.cnf中加入
replicate-do-db=test
重启slave,
show slave status发现两个线程工作正常
5)测试
在master的test数据的user表中添加了一条记录
然后在slave上通过show processlist看slave工作情况一切正常,
再查数据库数据似乎没有更新,查看slave错误日志
070307 16:45:16 [ERROR] Slave: Error 'Can't create database 'test'; database exists' on query. Default database: 'test'. Query: 'create database test', Error_code: 1007
070307 16:45:16 [ERROR] Error running query, slave SQL thread aborted. Fix the problem, and restart the slave SQL thread with "SLAVE START". We stopped at log 'MySQL(和PHP搭配之最佳组合)-bin.000040' position 70671
原来都是我当初拷贝数据惹的祸,因为主机日志在我建数据库的时候就开始了,所以我拷贝数据多此一举,于是
我删除拷贝的数据库,一切ok
