yum repository 수정

vi /etc/yum.repos.d/centos-base.repo 를 열어서 mirrorlist 대신 baseurl 을 추가

[base]
name=CentOS-$releasever - Base
#mirrorlist=http://mirrorlist.centos.org/?release=$releasever&arch=$basearch&repo=os
baseurl=http://centos.mirror.cdnetworks.com/$releasever/os/$basearch
gpgcheck=1
enabled=1
gpgkey=file:///etc/pki/rpm-gpg/RPM-GPG-KEY-CentOS-6
 
#released updates
[updates]
name=CentOS-$releasever - Updates
#mirrorlist=http://mirrorlist.centos.org/?release=$releasever&arch=$basearch&repo=updates
baseurl=http://centos.mirror.cdnetworks.com/$releasever/updates/$basearch
gpgcheck=1

gpgkey=file:///etc/pki/rpm-gpg/RPM-GPG-KEY-CentOS-6
#additional packages that may be useful

해당 파일 수정후 yum repository clean

yum clean all


기본 개발자툴 및 kernel 설치

# yum -y install net-tools
# yum -y install bzip2 kernel-devel make gcc perl
# yum -y groupinstall "Development Tools"
# reboot


Error

There are unfinished transactions remaining. You might consider running yum-complete-transaction, or “yum-complete-transaction –cleanup-only” and “yum history redo last”, first to finish them. If those don’t work you’ll have to try removing/installing packages by hand (maybe package-cleanup can help).

Resolution

Run the following commands in root;

/usr/bin/yum clean all
/usr/sbin/yum-complete-transaction

If yum-complete-transaction is not found please run (in root);
yum install yum-utils
