dns 主从同步问题最终解决了

很奇怪的问题. 主 修改了 serial .然后重启, 域名解释正常了, 但 nslookup 域名 从的 时候 .却是解释不出来.查看了下从的 zone 文件. 数据已经同步过来了. 却就是不解释.然后重启 从 以后 解释又正常了. 难道每次修改了主 以后 要重启 主和从?? 太麻烦了.

后来发现两个服务器的 时间不准备

然后更正服务器时间

修改时区：

首先 rm /etc/localtime
找到相应的时区文件 /usr/share/zoneinfo/Asia/Shanghai替换当前的/etc/localtime。
修改/etc/sysconfig/clock文件的内容为：
ZONE=”Asia/Shanghai”
UTC=false
ARC=false

然后修改时间

date -s 10:18:00

然后再测试同步问题,就正常了.呵呵查看了下日志

看下 主的日志部分

再看下从 的日志

看到了 xfer-in 和 xfer-out 证明 主从通讯很正常了.
