[KEDUIT] 클라우드 컴퓨팅과 보안솔루션을 활용한 DC 엔지니어 양성교육 - Day45

1. 서론

    오늘은 Linux 서버를 NFS Server, DHCP Server로 설정하는 방법을 배워보았다.

2. 본론

1. Linux

//Linux as a NFS server

//Linux as a DHCP server
# dnf install -y dhcp*
# firewall-cmd --add-service=dhcp --permanent
# firewall-cmd --reload
# systemctl disable dnsmasq
# ps -ef | grep dnsmasq
# pkill -9 PSNUM
# vim /etc/dhcp/dhcpd.conf
subnet 192.168.10.0 netmask 255.255.255.0 {
        range 192.168.10.1 192.168.10.99;
        option routers 192.168.10.254;
        option subnet-mask 255.255.255.0;
        option domain-name "kedu.edu";
        option domain-name-servers 192.168.10.100;
        default-lease-time 10000;
        max-lease-time 50000;
}
# systemctl enable --now dhcpd

//Linux as a DHCP relay agent
# dnf install -y dhcp-relay
# systemctl enable --now dhcrelay
# vim /lib/systemd/system/dhcrelay.service
ExecStart=/usr/sbin/dhcrelay -d --no-pid IPADD -i INTERFACE //끝에 ip주소, -i, interface이름 추가
# systemctl restart dhcrelay
# systemctl status dhcrelay
