Linux Bind DNS服务器软件 not found:2(Servfail) 错误

在Redhat9下使用Bind进行配置，启动服务，通过host获取解析结果时，一直出现host xxx not found:2(Servfail)的错误，到处找解决方法无果。。。

不停的搞，总算好了。写下过程，仅供参考！

先查看日志文件tail -n 20 /var/log/messages，得到的结果：

看日志没能看出什么不对劲。

后来从其可以正常服务的机子上找了相关配置文件进行对比，竟然是配置的语法错误！汗。。。。

named.conf正确的应该是这样的：

options { //全局选项
        directory "/var/named";	//设置Bind工作目录
};
controls { //运行本地主机存取,运行远程控制
        //inet 127.0.0.1 allow { localhost; } keys { rndckey; };
};
include "/etc/rndc.key";
zone  "." { //设置根域
	type hint;
	file  "named.ca";	//数据库文件为"named.ca"
};
zone  "0.0.127.in-addr.arpa" { //本地IP的逆向解析
	type master; 
	file  "0.0.127.in-addr.arpa.zone"; 
};
zone  "localhost" { //localhost域名解析
	type master; 
	file  "localhost.zone"; 
};
/*
zone  "29.168.192.in-addr.arpa" { //192.168.29.xIP逆向解析
	type master; 
	file  "29.168.192.in-addr.arpa.zone"; 
};
*/
zone  "our.com" { //our.com域名解析
	type master; 
	file  "our.com.zone"; 
};

解析文件是这样的：

$TTL 86400 ;						#TTL1天
@	IN	SOA	@  our.com (
			2011110400 ;	#区域版本号
			5H ; 				#辅助域名服务器更新时间间隔
			10M ; 			#再尝试时间间隔
			5D ; 				#辅助域名服务器更新超时时间
			1D ;		 		#资源生存周期1天
			)


	IN	NS	127.0.0.1

dns	IN	A	192.168.29.100 ;	#DNS服务器域名解析
www	IN	A	192.168.29.101 ;	#web服务器域名解析
ftp	IN	A	192.168.29.102 ;	#ftp服务器域名解析
web	IN	CNAME	www ;					#www的别名web

特别的注意的是行尾应有分号，而且分号之前应该有一个空格，我就死在这了，一个晚上啊。。。。

天啊。。。。

睡觉，晚安，珍爱生命，远离代码！！！
