1、启动系统，我是用iso镜像挂载，挂载到/media/cdrom
mkdir /media/cdrom
mount -a -t iso9660 -o loop /home/user1/CentOS-5.6-i386-bin-DVD.iso /media/cdrom
2、安装FTP服务（如果系统已带则在桌面 管理－服务器设置－服务 可以很方便的启动vsftpd服务）
cd /media/cdrom/CentOS
rpm -ivh vsftpd*
chkconfig vsftpd on
service vsftpd start
3、安装createrepo的软件包
cd /media/cdrom/CentOS
rpm -ivh createrepo*
4、拷贝系统盘里的文件到本机
cp -R /media/cdrom/CentOS /var/ftp/pub
cp -R /media/cdrom/repodata /var/ftp/pub
5、生成yum源
（1）生成依赖关系
[root@flyinweb repodata]# createrepo -g /var/ftp/pub/repodata/comps.xml /var/ftp/pub/CentOS/
2682/2682 - nfs-utils-lib-devel-1.0.8-7.6.el5.i386.rpm                         
Saving Primary metadata
Saving file lists metadata
Saving other metadata

若提示“Could not remove old metadata dir: .olddata”说目录有问题，不用在意，直接把目录删除掉就行了
rm -rf /var/ftp/pub/CentOS/.olddata
然后重新操作一遍就行了
（2）建立仓库文件
vim /etc/yum.repos.d/yum.repo
[Yum-ftp]
name=base
baseurl=ftp://yourip/pub/CentOS/
enabled=1
gpgcheck=1
gpgkey=file:///etc/pki/rpm-gpg/RPM-GPG-KEY-CentOS-5

下一次安装rpm直接用yum安装就可以了。如果其他机器需要访问此源的话把yum.repo拷过去就行了
yum install wireshark
OK成功

另，如果是redhat,或fedora, 得检查gpgkey=file:///etc/pki/rpm-gpg/RPM-GPG-KEY-CentOS-5 这个文件，只需进入目录/etc/pki/rpm-gpg/查看是哪个文件即可，否则会报错如下
yum install wireshark
warning: rpmts_HdrFromFdno: Header V3 DSA signature: NOKEY, key ID e8562897
不过错了也没关系，这是因为yum安装了不同版本的GPG keys造成的，按上述方法解决，或者
rpm --import /etc/pki/rpm-gpg/RPM*
再重新yum install wireshark
OK，问题解决，已经装上了
yum install wireshark。注意这样并无法使用wireshark命令和图形界面。但提供了抓包基本功能。
yum install wireshark-gnome。这样就可以方便的使用了。

OK，进入桌面可以正常启动wireshark

Sometimes it can be handy to set up your own repository to prevent from downloading the remote repository over and over again. This tutorial shows how to create a CentOS mirror for your local network. If you have to install multiple systems in your local network then all needed packages can be downloaded over the fast LAN connection, thus saving your internet bandwidth.

Create the Directories:

mkdir -pv /var/www/html/centos/4/{os,updates}/i386

Replacing 4 and i386 with your major version and architecture.
Additionally you'll need some deeper directories. This is the correct location to copy the CD/DVD rpms.

The Base Repository

Copy the RPMs from the CDs/DVD to /var/www/html/centos/base.

Create the base repository headers:

createrepo /var/www/html/centos/4/os/i386/

The Updates Repository

Select an rsync mirror for updates: check out this list of aviable mirrors: Centos OS Mirror list and these are identified with rsync.

For example: rsync://ftp.belnet.be/packages/centos/

The mirrors share a common structure for updates. Simply append /updates/<d version>/<base arch>.

Rsync to create the updates-released repository:

/usr/bin/rsync -avrt rsync://ftp.riken.jp/centos/4/updates/i386 --exclude=debug/ /var/www/html/centos/4/updates/

This will create a complete update repository at /var/www/html/centos/4/updates/i386. The repodata directory will be created with all of the headers.

You can additionally pipe this into mail to receive an email when updates are available.

Next I would advise to setup a cron job to run the rsync (above). In this manner your repository is kept updated and only new updates and headers will be downloaded to your repository.

Yum Configuration

Edit yum.conf:

vi /etc/yum.repos.d/CentOS-Base.repo

[base]
name=CentOS-$releasever - Base
baseurl=http://192.168.*.*/centos/$releasever/os/$basearch/
#mirrorlist=http://mirrorlist.centos.org/?release=$releasever&arch=$basearch&repo=os
#baseurl=http://mirror.centos.org/centos/$releasever/os/$basearch/
gpgcheck=1
gpgkey=http://mirror.centos.org/centos/RPM-GPG-KEY-CentOS-5
#released updates
[update]
name=CentOS-$releasever - Updates
baseurl=http://192.168.*.*/centos/$releasever/updates/$basearch/
#mirrorlist=http://mirrorlist.centos.org/?release=$releasever&arch=$basearch&repo=updates
#baseurl=http://mirror.centos.org/centos/$releasever/updates/$basearch/
gpgcheck=1
gpgkey=http://mirror.centos.org/centos/RPM-GPG-KEY-CentOS-5

That's it.
