网络&本地yum源安装

 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 -g ./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
