配置完毕运行：
/usr/sbin/named -u named -gc /etc/named.conf

提示

...................
Nov 27 13:17:58 dns named[1966]: zone localhost.zone/IN: has no NS records
Nov 27 13:17:58 dns named[1966]: zone named.local/IN: has no NS records
Nov 27 13:17:58 dns named[1966]: zone hk.hn/IN: has no NS records
...................

解决方法：
原因为直接copy web上的配置文件，配置文件中的NS行没有空格或tab，添加上一个tab就可以了。
如"IN NS localhost".换成" IN NS localhost."即可。

Mysql实现实时备份

root , 2009/06/14 23:56 , MYSQL , 评论(0) , 阅读(1824) , Via 本站原创

　　目前成熟的实时备份为双机(master/slave)，是基于同步日志事件来实现，那单机如何实现具有增量的备份呢？可以借用双机的原理，非常简单，实施步骤如下：
Mysql版本：mysql4.0+

1、vi my.cfg
[mysqld]
log-update=/home/backup/update #添加该行

2、service mysql restart
会在/home/backup/update00001文件，内容为数据库变化的所有SQL(没有select)

3、每天的全备,mysql4.0+最简单就是备份data目录。
service mysql stop
tar -czf data(日期).tar.gz mysql/data
service mysql start
当mysql启动时系统会自动在/home/backup/创建update0000*的文件，那我们可以用该文件作为当天全备的增量实时备份。

4、数据还原
service mysql stop
tar -zxvf data(日期).tar.gz mysql/
service mysql start
mysqladmin -u -p /home/backup/update0000*

如想还原昨天、前天的数据只需要找相应的update0000*来还原即可：）
