Resolve CentOS 7 DHCP server-no subnet declaration for start (no IPV4 addresses.)

The above configuration is a Hyper-V installation of CentOS 7.0

The way to install a DHCP server is

Yum Install DHCPD

After installation and configuration, there is an error when running

The error prompts are as follows:

 for Start (no IPV4 addresses.)--- error one .... configured to listenon any interfaces! ---error two.

-----------------------------------

Analyze the problem:

The reason for the error is: There is no DHCPD module in the/etc/rc.d/init.d/directory.

Workaround:

Copy/USR/BIN/DHCPD to/etc/rc.d/init.d/directory

Restart the service systemctl restart Dhcpd.service #当没有出现任何提示的时候, indicating that it started successfully.

For a look, debug output:

A word in the red area appears. It proves that DHCP is working properly.
