本文记录了centos6升级的步骤，升级过程在网络不好的情况下升级的方法
1、创建目录
mkdir /media/cd1
mkdir /media/cd2
2、挂载，-o说明使用本地文件当作盘符来挂载
mount -o loop CentOS-6.5-x86_64-bin-DVD1.iso /media/cd1
mount -o loop CentOS-6.5-x86_64-bin-DVD2.iso /media/cd2
3、编辑挂载文件
vi /etc/yum.repos.d/CentOS-Media.repo
文件内容参考
# yum --disablerepo=\* --enablerepo=c6-media [command]
[c6-media]
name=CentOS-$releasever - Media
baseurl=
file:///media/cd1
file:///media/cd2
file:///media/CentOS/
file:///media/cdrom/
file:///media/cdrecorder/
gpgcheck=1
enabled=0
gpgkey=file:///etc/pki/rpm-gpg/RPM-GPG-KEY-CentOS-6
4、执行升级
yum --disablerepo=\* --enablerepo=c6-media update
出现问题
yum --disablerepo=\* --enablerepo=c6-media update
Not found
You could try using --skip-broken to work around the problem
You could try running: rpm -Va --nofiles --nodigest
执行
yum update glibc* yum* rpm* python* -y
yum -y remove qpid-cpp-client -y
主要是第二个命令
附上centos5.X的本地源配置方法：
[root@rac1 ~]# mkdir -p /mnt/soft
[root@rac1 ~]# mount -o loop /dev/cdrom
cdrom cdrom-hdc
[root@rac1 ~]# mount -o loop /dev/cdrom/ /mnt/soft/
/dev/cdrom/: 不是目录
[root@rac1 ~]# mount -o loop /dev/cdrom /mnt/soft/
[root@rac1 ~]# mkdir -p /data/Centos/i386
[root@rac1 ~]# cp -rf /mnt/soft/CentOS/ /data/Centos/i386/
安装服务端设置软件仓库及信息文件
rpm -ivh /mnt/soft/CentOS/createrepo-0.4.11-3.el5.noarch.rpm
cracklib-2.8.9-3.3.i386.rpm
cracklib-2.8.9-3.3.x86_64.rpm
cracklib-dicts-2.8.9-3.3.x86_64.rpm
crash-4.1.2-4.el5.centos.x86_64.rpm
crash-devel-4.1.2-4.el5.centos.i386.rpm
crash-devel-4.1.2-4.el5.centos.x86_64.rpm
createrepo-0.4.11-3.el5.noarch.rpm
crontabs-1.10-8.noarch.rpm
crypto-utils-2.3-2.el5.x86_64.rpm
cryptsetup-luks-1.0.3-5.el5.i386.rpm
cryptsetup-luks-1.0.3-5.el5.x86_64.rpm
cryptsetup-luks-devel-1.0.3-5.el5.i386.rpm
cryptsetup-luks-devel-1.0.3-5.el5.x86_64.rpm
生成客户端所需的信息文件
[root@rac1 ~]# createrepo -g /mnt/soft/repodata/comps.xml /data/Centos/i386/

Saving Primary metadata
Saving file lists metadata
Saving other metadata
[root@rac1 ~]# cp /mnt/soft/RPM-GPG-KEY-CentOS-5 /data/Centos/i386/ 将key文件（用于客户端与服务端的认证）拷入指定目录/data/Centos/i386 下
备份原有yum文件
[root@rac1 ~]# cp /etc/yum.repos.d/CentOS-Base.repo /etc/yum.repos.d/CentOS-Base.repobak
清空yum文件
[root@rac1 ~]# echo ‘’ /etc/yum.repos.d/CentOS-Base.repo
编辑文件
[root@rac1 ~]# vi /etc/yum.repos.d/CentOS-Base.repo
[base]
name=CentOS5.5-base
baseurl=file:///data/Centos/i386/
enable=1
gpgcheck=1
gpgkey=file:///data/Centos/i386/RPM-GPG-KEY-CentOS-5
[root@rac1 ~]# yum clean all
Loaded plugins: fastestmirror
Config Error: File contains parsing errors: file://///etc/yum.repos.d/CentOS-Base.repo

[line 4]: enable=1
[line 5]: gpgcheck=1
[line 6]: gpgkey=file:///data/Centos/i386/RPM-GPG-KEY-CentOS-5
此处文件中有空格，此后报错，去掉空格
[root@rac1 ~]# vi /etc/yum.repos.d/CentOS-Base.repo
[base]
name=CentOS5.5-base
baseurl=file:///data/Centos/i386/
enable=1
gpgcheck=1
gpgkey=file:///data/Centos/i386/RPM-GPG-KEY-CentOS-5
然后
[root@rac1 ~]# yum clean all
Loaded plugins: fastestmirror
Cleaning up Everything

如果清除的时候报
[root@rac1 ~]# yum clean all
Loaded plugins: fastestmirror
