2. /etc/resolv.conf 확인(nameserver 정상)

[root@server1 ~]# cat /etc/resolv.conf
# Generated by NetworkManager
search example.com
nameserver 8.8.8.8

 

3. ping 확인(ping 확인)

[root@server1 ~]# ping 8.8.8.8
PING 8.8.8.8 (8.8.8.8) 56(84) bytes of data.

nameserver  와 ping 은 정상인 것으로 보아 정상이였다.

 

다만, yum 명령어 시 에러가 발생하였다.

 

이와 같은 에러를 해결 하려면 아래와 같이 진행 하면 된다.

 

1. yum 프로세스 중지

[root@localhost ~]# ps -ef | grep yum
root       3399   3129 12 20:25 ?        00:00:29 /usr/bin/python /usr/share/PackageKit/helpers/yum/yumBackend.py get-updates none
root       4350   3728  0 20:29 pts/1    00:00:00 grep --color=auto yum
[root@localhost ~]# kill -9 3728

 

2. yum.pid 제거
