There was a need to configure the dhcp server on CentOS. There will be several computers on the network and an extension is possible. In general, you just need to configure the server so that it issues addresses from 192.168.1.10 to 192.168.1.254. - FAILED. Please either help with the config, or give a link to a clever guide.

    The file is obtained from dhcpd.conf.sample by editing - deleting unnecessary and adding the necessary items.

    PS file with FreeBSD with ISC dhcpd, but the principle is about the same everywhere.

    PPS if at start you get

    I tried to use all sorts of manuals from the network, but everything I received at the start was FAILED.

    be sure to see the logs See there for sure

    • or no configuration file,
    • or it is incorrect (it is easy to omit the semicolon or the closing brace).
    • Well, or the problem is something else, but it will be described.

    Logs search somewhere in / var / log /

    • If I understand correctly, then the first 4 options are required? And then comes the announcement of 2 pools and 2 static hosts? - Sergey
    • I would not say that they are 100% mandatory, but it was quieter for me to ask than to use the default values. Yes, further two pools and three hosts. And attention - the hosts are not quite static. I would even say that it is not static at all. And dynamically receive a fixed IP by MAC address. This is convenient in that you can always access a PC directly with IP knowledge. I commented out the interfaces, but in general it is possible to start dhcpd on specific interfaces. - gecube
    • Yes, I apologize, not static, but reserved (at least in Windows it is so called). Thank you, I hope to start. - Sergey
    • Alas, it did not start. dhcpd log is missing. - Sergey
    • Log can not be! Search. Can write to any / var / log / messages or daemon.log - gecube
