==== - repo file ====

目前centos6停止更新了，使用国内镜像的repo也是有问题的，建议直接使用本地iso文件yum源的方式来 yum install。

<file bash  CentOS-Base.repo.tsinghua>
# 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.

===== - 使用iso文件搭建本地源 =====

1. 使用如下命令新建挂载点并挂载

<code bash>
sudo mkdir /media/iso
sudo mkdir /media/dvd1
sudo mkdir /media/dvd2
sudo mv  /home/user/CentOS-6.5-x86_64-bin-DVD1.iso   /media/iso
sudo mv  /home/user/CentOS-6.5-x86_64-bin-DVD2.iso   /media/iso
#挂载centos安装盘(两个iso)
sudo mount -o loop /media/iso/CentOS-6.5-x86_64-bin-DVD1.iso  /media/dvd1/
sudo mount -o loop /media/iso/CentOS-6.5-x86_64-bin-DVD2.iso  /media/dvd2/

</code>

<color #ed1c24>注：如果刚刚装好的系统，nfs功能可能是没有安装的，即不能通过NFS网络文件系统挂载远程的ISO文件，此时只能使用光盘。如果是虚拟机安装，那么直接在虚拟机设置里加载光盘iso文件，即可，它一般会自动mount iso。如果是物理实体机，可能就真的需要一个光驱了。。。。</color>

2. 修改yum源配置，把CentOS-Base.repo文件备份
<code>
cd /etc/yum.repos.d/
####   将除CentOS-Media.repo之外的其它repo文件全部mv成.bak文件备份，全部使用本地iso源。

mv CentOS-Base.repo CentOS-Base.repo.bak
...
</code>

<code>
文件：CentOS-Media.repo
#修改如下内容
enabled=1
#将baseurl中的路径修改为 file://media/dvd1和file://media/dvd2
#保存退出

baseurl=file:///media/dvd1/    #根据实际mount目录修改
      file:///media/dvd2/
gpgckeck=1
enabled=1   #此处要enable=1使能
</code>

3. 清空yum已存在的所有源信息,重新生成缓存
<code>
yum clean all;  yum makecache

</code>

4. 查看本地源的所有软件
<code>
yum list 
</code>




===== - yum EPEL源 =====

EPEL的全称叫 Extra Packages for Enterprise Linux 。EPEL是由 Fedora 社区打造，为 RHEL 及衍生发行版如 CentOS、Scientific Linux 等提供高质量软件包的项目。装上了 EPEL之后，就相当于添加了一个第三方源。

以安装xfce为例：
<code>
根据系统版本打开相应的链接：
CentOS 5 32位：http://download.fedoraproject.org/pub/epel/5/i386/
CentOS 5 64位：http://download.fedoraproject.org/pub/epel/5/x86_64/
CentOS 6 32位：http://download.fedoraproject.org/pub/epel/6/i386/
CentOS 6 64位：http://download.fedoraproject.org/pub/epel/6/x86_64/
查找“epel”，应该会找到一个“epel-release-X-X.noarch.rpm”的软件包。下载，安装之。

$ wget http://download.Fedoraproject.org/pub/epel/6/x86_64/epel-release-6-5.noarch.rpm
$ sudo rpm -ivh epel-release-6-5.noarch.rpm
$ sudo yum search xfce
$ sudo yum groupinfo xfce
$ sudo yum groupinstall xfce
$ sudo yum groupinstall Fonts    （可选安装）
然后用xfce4-session就可以启动了，比如加到.vnc的xstartup里。

===== - 其它软件升级 =====

tcl需要重新安装tcl8.6版本，-- 8.5版本不支持
<code tcl>format "b" 3</code>


===== - 其它 =====

1、在64系统里执行32位程序如果出现/lib/ld-linux.so.2: bad ELF interpreter: No such file or directory，安装下glic即可

sudo yum install -y glibc.i686

2、error while loading shared libraries: libz.so.1: cannot open shared object file: No such file or directory

sudo yum install -y zlib.i686
