This article is empty when you enter it, but you can see a comment (# see/usr/share/doc/dhcp */dhcpd. conf. sample) indicates: see/usr/share/doc/dhcp */dhcpd. conf. sample
5: Refer to/usr/share/doc/dhcp */dhcpd in the previous step. conf. sample document, in vim etc/dhcpd. run the following command in conf: r/usr/share/doc/dhcp */dhcpd. conf. sample to read the content in this document

This is the dhcp configuration on my machine. Some modifications need to be made in it. Here I have made two scopes: one with the IP address range 192.168.60.0 and the other with the IP address range 192.168.70.0, you can also make them into a super scope, but you need to add a command.
Add a line "shared-network AAA (super-scope name) {" to the end of row 7th, then write a line "}" in the last line, and finally save and exit wq.
