如何在CentOS 6.3上安装nslookup

nslookup是bind-utils软件包的一部分。请注意，host、dig和nslookup也是bind工具的一部分。如果没有安装bind-utils包，当你尝试nslookup任何域时，你会得到以下错误。

[root@centos63 ~]# nslookup
-bash: nslookup: command not found.3

　　

要在CentOS 6.3中安装nslookup，只需运行这个命令。

[root@centos63 ~]# yum install bind-utils -y
Loaded plugins: fastestmirror, presto
Loading mirror speeds from cached hostfile
