Rocky Linux 9에서 bonding 설정 작업
1. /etc/default/grub 파일에 추가(아래 명령어 자동 추가)
# grubby --update-kernel=ALL --args="ipv6.disable=1 net.ifnames=0 biosdevname=0"
2. bond 설정 추가(ip도 같이 추가가 편함)
# nmcli connection add type bond ifname bond0 mode balance-rr ipv4.method manual ipv4.addresses 192.168.78.129/24 ipv4.gateway 192.168.78.2 ipv6.method ignore ipv4.dns 8.8.8.8,8.8.4.4
3. bond slave 설정 추가(eth0~3 추가)
# nmcli connection add type ethernet ifname eth0 master bond0
# nmcli connection add type ethernet ifname eth1 master bond0
# nmcli connection add type ethernet ifname eth2 master bond0
# nmcli connection add type ethernet ifname eth3 master bond0
4. 적용(eth로 인터페이스 바뀌기 전이면 reboot)
reboot 또는 systemctl restart NetworkManager
5. 확인
# nmcli connection
# ip a
# ifconfig
# cat /proc/net/bonding/bond0
* 파일이 여럿 생성되어 지저분할때 삭제 명령어(nmcli 명령과 ls 명령으로 지저분한 파일 확인)
nmcli connection delete bond-bond0-1
설정파일 값
#cat bond-bond0.nmconnection

ens160이란 인터페이스를 eth0으로 변경
mv /etc/NetworkManager/system-connections/ens160.nmconnection /etc/NetworkManager/system-connections/eth0.nmconnection
바꾼 파일의 ens160을 eth0으로 변경
sed -i 's/ens160/eth0/g' /etc/NetworkManager/system-connections/eth0.nmconnection
