yum-安装（本地yum源&网络yum源）-001

yum源在vsftp网络提供的安装步骤

1）安装yum源服务器

//首先安装存放yum源的服务器

#rpm -ivh vsftpd-2.0.5-12.el5

#service vaftpd restart

#cd /var/ftp/pub

//创建挂载点 并把镜像盘挂载

#mkdir /mnt/cdrom

#mount /dev/cdrom /mnt/cdrom

#cp -a /mnt/cdrom pub

2)安装createrepo工具

//创建yum源通用数据库（生成RPM数据库）

#cd /var/ftp/pub/cdrom/Server

#createrepo -g ./repodata/comps-rhel5-server-core.xml ./

#cd /var/ftp/pub/cdrom/Cluster

#createrepo -9 ./repodata/comps-rhel5-cluster.xml ./

[root@fly Server]# cd /var/ftp/pub/cdrom/VT

[root@fly VT]# createrepo -g ./repodata/comps-rhel5-vt.xml ./

[root@fly VT]# cd /var/ftp/pub/cdrom/ClusterStorage

[root@fly ClusterStorage]# createrepo -g ./repodata/comps-rhel5-cluster-st.xml ./

3)

编写yum源配置文件

#vim /etc/yum.repos.d/myyum.repo

[root@fly ~]# vim /etc/yum.repos.d/myyum.repo

//[ ]内的是仓库的名字

//命名最好是[rhel-xxx]，否则yum的某些功能可能会不能实现，比如kickstart工具安装系统是软件组件选择没法读取。

//name是仓库的描述也可以说是名字

//baseurl 仓库的位置

//enabled 是否启用这个仓库，1为起用，0为禁用

//gpgcheck 是否检查GPG签名（用来验证要安装的包是不是REDHAT官方的）

[rhel-server]

name=server

baseurl=ftp://192.168.100.88/pub/cdrom/Server

enabled=1

//签名校验最好为1允许，有些软件签名校验后才能安装

//签名要导入# rpm --import /etc/pki/rpm-gpg/RPM-GPG-KEY-redhat-release

gpgcheck=1

gpgkey=ftp://192.168.100.88/pub/cdrom/RPM-GPG-KEY-redhat-release

[rhel-vt]

name=vt

baseurl=ftp://192.168.100.88/pub/cdrom/VT

enabled=1

gpgcheck=1

gpgkey=ftp://192.168.100.88/pub/cdrom/RPM-GPG-KEY-redhat-release

[rhel-cluster]

name=cluster

baseurl=ftp://192.168.100.88/pub/cdrom/Cluster

enabled=1

gpgcheck=1

gpgkey=ftp://192.168.100.88/pub/cdrom/RPM-GPG-KEY-redhat-release

[rhel-clusterstorage]

name=clusterstorage

baseurl=ftp://192.168.100.88/pub/cdrom/ClusterStorage

enabled=1

gpgcheck=1

gpgkey=ftp://192.168.100.88/pub/cdrom/RPM-GPG-KEY-redhat-release

------------

本地yum源安装

1）如果安装改为本地yum源需要事先 yum clean all

#yum clean all

//创建挂载点 并把镜像盘挂载

#mkdir /mnt/cdrom

#mount /dev/cdrom /mnt/cdrom

//linux 有的版本不一样 挂载是只读时候可能会出现创建源时出现不可用

//可以把光盘拷贝到某个文件夹，以上面服务器的文件夹为例

#cp -a /mnt/cdrom pub

2)安装createrepo工具

#cd /var/ftp/pub/cdrom/Server

#createrepo -g ./repodata/comps-rhel5-server-core.xml ./

#cd /var/ftp/pub/cdrom/Cluster

#createrepo -9 ./repodata/comps-rhel5-cluster.xml ./

[root@fly Server]# cd /var/ftp/pub/cdrom/VT

[root@fly VT]# createrepo -g ./repodata/comps-rhel5-vt.xml ./

[root@fly VT]# cd /var/ftp/pub/cdrom/ClusterStorage

[root@fly ClusterStorage]# createrepo -g ./repodata/comps-rhel5-cluster-st.xml ./

3)vim /etc/yum.repos.d/myyum.repo

[root@fly ~]# vim /etc/yum.repos.d/myyum.repo

[rhel-server]

name=server

baseurl=file：///var/ftp/pub/cdrom/Server

enabled=1

gpgcheck=1

gpgkey=file：///var/ftp/pub/cdrom/RPM-GPG-KEY-redhat-release

[rhel-vt]

name=vt

baseurl=file：///var/ftp/pub/cdrom/VT

enabled=1

gpgcheck=1

gpgkey=file：///var/ftp/pub/cdrom/RPM-GPG-KEY-redhat-release

[rhel-cluster]

name=cluster

baseurl=file：///var/ftp/pub/cdrom/Cluster

enabled=1

gpgcheck=1

gpgkey=file：///var/ftp/pub/cdrom/RPM-GPG-KEY-redhat-release

[rhel-clusterstorage]

name=clusterstorage

baseurl=file：///var/ftp/pub/cdrom/ClusterStorage

enabled=1

gpgcheck=1

gpgkey=file：///var/ftp/pub/cdrom/RPM-GPG-KEY-redhat-release

----------

注：可以不拷贝rpm软件包，直接挂载光盘创建本地yum源，

其他同理

#mount --bind /mnt/yum/repodata/ /mnt/cdrom/Server/repodata /

1）如果安装改为本地yum源需要事先 yum clean all

#yum clean all

//创建挂载点 并把镜像盘挂载

#mkdir /mnt/yum

#mkdir /mnt/cdrom

#mount /dev/cdrom/ /mnt/cdrom/

2)安装createrepo工具

#createrepo -o /mnt/yum/ -g /mnt/cdrom/repodata/comps-rhel5-server-core.xml /mnt/cdrom/Server/

#createrepo -o /mnt/yum/ -g /mnt/cdrom/repodata/comps-rhel5-cluster.xml /mnt/cdrom/

#createrepo -o /mnt/yum/ -g /mnt/cdrom/repodata/comps-rhel5-vt.xml /mnt/cdrom/

#createrepo -o /mnt/yum/ -g /mnt/cdrom/repodata/comps-rhel5-cluster-st.xml /mnt/cdrom/

3)vim /etc/yum.repos.d/myyum.repo

[root@fly ~]# vim /etc/yum.repos.d/myyum.repo

[rhel-server]

name=server

baseurl=file：///mnt/cdrom/Server

enabled=1

gpgcheck=1

gpgkey=file：///etc/pki/rpm-gpg/RPM-GPG-KEY-redhat-release

[rhel-vt]

name=vt

baseurl=file：///mnt/cdrom/VT

enabled=1

gpgcheck=1

gpgkey=file：///etc/pki/rpm-gpg/RPM-GPG-KEY-redhat-release

[rhel-cluster]

name=cluster

baseurl=file：///mnt/cdrom/Cluster

enabled=1

gpgcheck=1

gpgkey=file：///etc/pki/rpm-gpg/RPM-GPG-KEY-redhat-release

[rhel-clusterstorage]

name=clusterstorage

baseurl=file：///mnt/cdrom/ClusterStorage

enabled=1

gpgcheck=1

gpgkey=file：///etc/pki/rpm-gpg/RPM-GPG-KEY-redhat-release

---------

#yum list all

//测试是否安装成功

安装组的例子：

安装图形kde

组要用引号引用

[root@fly Server]# yum grouplist "KDE"
