이유

yum이 외국의 주소를 사용하고 있어 접속이 오래 걸려서 time out 때문에 접속이 끊긴다

# CentOS-Base.repo
#
# The mirror system uses the connecting IP address of the client and the
# update status of each mirror to pick mirrors that are updated to and
# geographically close to the client.  You should use this for CentOS updates
# unless you are manually picking other mirrors.
#
# If the mirrorlist= does not work for you, as a fall back you can try the
# remarked out baseurl= line instead.

reboot

 

yum 사용 가능

 

 

yum 업데이트 후 사용

yum update

 

 

 

안 될 때

가끔 resolv.conf를 수정해도 계속 초기화될 때가 있다

NetworkManager가 계속 수정하는 것.

그럴 때는 /etc/sysconfig/network-scripts/ifcfg-ens192 파일을 직접 수정해줄 것

 

맨 아래 추가

DNS1=8.8.8.8

DNS2=168.126.63.1

DNS3=164.124.101.2

 

그리고 네트워크 재기동

systemctl restart network

systemctl restart NetworkManager

 

그 후에 yum update 하면 잘 실행된다
