Question: I followed your tutorial – how to identify the DNS server IP address configured on my CentOS 6 using the dig command and ran into an error as shown below:
-bash: dig: command not found
Well, the error was clear. So I tried to install dig via yum as shown below:
[root@cloud2 ~]# yum install dig
Unfortunately, yum couldn’t find a package in the repository. Please help me to install dig on CentOS-6?
Solution:
Sometimes the command might be shipped as part of a package. It means, dig is not a package by itself and it’s packaged in bind-utils. So it’s a good idea to find out which package the command dig belongs to? Follow the tutorial: How to Find Which Package an Executable or File belongs to in RedHat/CentOS/Fedora?
[root@cloud2 ~]# yum provides *bin/dig Loaded plugins: fastestmirror Loading mirror speeds from cached hostfile * base: centos.excellmedia.net * extras: centos.excellmedia.net * remi-safe: mirror.innosol.asia * updates: centos.excellmedia.net 32:bind-utils-9.8.2-0.37.rc1.el6.x86_64 : Utilities for querying DNS name servers Repo : base Matched from: Filename : /usr/bin/dig ... ...
From the above output, it clear that the dig command is a part of BIND utilities. Now go ahead and install BIND utilities as shown below:
[root@cloud2 ~]# yum install bind-utils
After successful installation, check if the dig command is installed and its path:
[root@cloud2 ~]# whereis dig dig: /usr/bin/dig /usr/share/man/man1/dig.1.gz [root@cloud2 ~]# which dig /usr/bin/dig [root@cloud2 ~]#
Now, learn how to use dig command.
