有关BIND升级报错的解决方法

系统：redflag DC5.0sp2 BIND版本：9.2.4
升级BIND至9.4.2
操作步骤
1.登录到应用服务器，切换到root用户。
2. 关闭named服务
命令：#/etc/init.d/named stop
3. 安装BIND升级包
命令：# tar xvfz bind-9.4.2.tar.gz
# cd bind-9.4.2
# ./configure --prefix=/usr/local/named --sysconfdir=/etc/--localstatedir=/var --enable-threads
# make
# make install
4.生成/etc/rndc.conf
#cd /usr/local/named/sbin
#rndc-confgen>/etc/rndc.conf
5.生成/etc/named.conf文件
# cd /etc
#tail -10 rndc.conf | head -9 | sed s /#\ //g >named.conf
6.从rndc.conf中提取rndc.key
#cat rndc.conf | head -5 >rndc.key
7.编辑/etc/init.d/named启动,用/usr/local/named/sbin替换/usr/sbin,
将-u named删除
8. 恢复bind配置文件名称命令：#tar xzvf /root/bind_backup.tar.gz -C /
9. 配置BIND服务
修改：/etc/named.conf中/usr/sbin为/usr/local/named/sbin
命令：#vi /etc/named.conf
:%s#/usr/sbin/#/usr/local/named/sbin/#
10.重新启动即可。
# service named restart
#service named status
--------------------------------------------------------
升级步骤如上，但是在升级的过程中会出现如下的问题：
1,查看service named status的时候出现如下：
# service named status
rndc: connect failed: 127.0.0.1#953: connection refused
解决方法：vi /etc/init.d/named 将-u named删除即可。
daemon /usr/local/named/sbin/$named -u named ${OPTIONS};
2,查看service named status的时候如出现如下问题：
# service named status
rndc: connection to remote host closed
This may indicate that
* the remote server is using an older version of the command protocol,
* this host is not authorized to connect,
* the clocks are not syncronized, or
* the key is invalid.
解决方法：请检查/etc/named.conf rndc.conf rndc.key中的key是否一致，如果不一致，
请严格执行以上实施步骤的4-7步。更改后的重启，正常的状态如下：
[root@young etc]# service named restart
停止 named： [确定]
启动 named： [确定]
[root@young etc]# service named status
