[root@linux-tys root]# rpm -qa | grep bind
bind-9.2.1-16 -----这个版本的DNS不太稳定,所以要升级到9.2.1之上的版本
redhat-config-bind-1.9.0-13
bind-utils-9.2.1-16
ypbind-1.11-4
1、删除9.2.1的包,因这个版本不太稳定
[root@linux-tys root]# rpm -e bind-9.2.1-16 ----删除包时可以看到提示有关联的包,需要先删除
error: Failed dependencies:
bind is needed by (installed) redhat-config-bind-1.9.0-13
bind is needed by (installed) caching-nameserver-7.2-7
bind >= 9.1.3-0.rc2.3 is needed by (installed) caching-nameserver-7.2-7
[root@linux-tys root]# rpm -e caching-nameserver-7.2-7

[root@linux-tys root]# rpm -e redhat-config-bind-1.9.0-13 ----删除图形配置工具
[root@linux-tys root]# rpm -e bind-9.2.1-16 ----删除DNS包

[root@linux-tys root]# rm -f /etc/rndc.key.rpmsave

[root@linux-tys root]# rpm -e bind-utils-9.2.1-16
[root@linux-tys root]# rpm -qa | grep bind
ypbind-1.11-4 -----此包与DNS无关
注意:卸载时最后卸工具包,安装时要先安装工具包
2、安装9.2.2的包
[root@linux-tys sharedoc]# rpm -ivh bind-utils-9.2.2-13Thiz.i586.rpm ----应先安装工具包
