3. data01 디스크 fdisk & 포맷 & 마운트 & fstab등록

4. ipv6 disable

# vi /etc/sysctl.conf net.ipv6.conf.all.disable_ipv6 = 1 net.ipv6.conf.default.disable_ipv6 = 1 # shutdown -rf now 재시작 # nmcli device show 재시작 후 네트워크 확인하여 ipv6없으면 적용됨

5. 내부 yum repository가 구축되어 있을 때 지정하기

. etc에 내부 yum repository를 참조하도록 repo설정 파일을 해당 경로로 지정한다.

# vi /etc/yum.repos.d /birepos.repo [birepos] name=birepos Internal Repository baseurl=http://10.203.9.208/repos/centos/iso/ enabled=1 gpgcheck=0

. yum repolist 목록에 뜨면 성공!

# yum repolist ... birepos                        birepos Internal Repository    9,363 ... # mkdir -p /etc/yum.repos.d/ ~/etc/yum.repos.d/ [root@bidevkylinm1 yum.repos.d]# mv C*  ~/etc/yum.repos.d/ [root@bidevkylinm1 yum.repos.d]# yum repolist Loaded plugins: fastestmirror Determining fastest mirrors repo id                                                                                                                   repo name                                                                                                                                      status birepos                                                                                                                   birepos Internal Repository                                                                                                                    9,363 repolist: 9,363

. repolist를 한개만 남겨두고 지워버리자

# mkdir -p /etc/yum.repos.d/ ~/etc/yum.repos.d/ # mv C* ~/etc/yum.repos.d/ # yum repolist Loaded plugins: fastestmirror Determining fastest mirrors repo id            repo name          status birepos            birepos              Internal Repository       9,363 repolist: 9,363
