mysqldump -uroot -psphinx lb8844 oho_ask_question>/usr/local/ask.sql
退出数据库，导入sql文件
mysql -uroot -p123456 lb8844 < lb8844_2009.sql
数据库复制
主机/etc/my.cnf设置
server-id = 10（不设置为1，因为1通常是服务器的默认值，容易混淆）
打开二进制日志
log-bin=mysql-bin
binlog_format=mixed
重启mysql
service mysql restart
从机/etc/my.cnf设置
server-id = 2
master-host=192.168.10.201
master-user=sync
master-password=8844sync
master-connect-retry=10
replicate-do-db=lb8844
binlog-ignore-db=mysql
重启mysql
service mysql restart
在主机中查看是否打开二进制日志
进入mysql
show master status;
mysql> show master status;

##重新设置二进制日志
reset master；
mysql> reset master;

stop slave；
reset slave；
start slave；
以上三项为重启slave；
