1.以HP Server远程控制台为例。iLO > Remote Console > Virtual Drives > Image File CD/DVD-ROM , 选择要挂载的iso

2.将iso挂载到/mnt下，先查看/dev下的设备，新增了cdrom1

# mount /dev/cdrom1 /mnt

# cd /mnt

注：如果是封闭环境的虚拟机，可以把iso文件传到某路径，然后挂载到/mnt
# mount rhel-server-7.6-x86_64-dvd.iso /mnt
mount: /dev/loop0 is write-protected, mounting read-only

3.修改yum配置文件，注意：如果安装过程中少了包则要修改[rhel-source]否则不改，红色的“[rhel-source-XXX]”段落是加的。

# vi /etc/yum.repos.d/rhel-source.repo

[rhel-source]

name=Red Hat Enterprise Linux $releasever - $basearch - Source

baseurl=file:///mnt/

enabled=1

gpgcheck=0

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

[rhel-source-HA]

name=Red Hat Enterprise Linux $releasever - $basearch - Source

baseurl=file:///mnt/HighAvailability

enabled=1

gpgcheck=0

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

[rhel-source-LB]

name=Red Hat Enterprise Linux $releasever - $basearch - Source

baseurl=file:///mnt/LoadBalancer

enabled=1

gpgcheck=0

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

[rhel-source-RS]

name=Red Hat Enterprise Linux $releasever - $basearch - Source

baseurl=file:///mnt/ResilientStorage

enabled=1

gpgcheck=0

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

[rhel-source-beta]

name=Red Hat Enterprise Linux $releasever Beta - $basearch - Source

baseurl=ftp://ftp.redhat.com/pub/redhat/linux/beta/$releasever/en/os/SRPMS/

enabled=0

gpgcheck=1

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

注：以上是rhel6的情况，rhel7额外的软件包在路径addons/下

yum —disablerepo=* —enablerepo=rhel-source install pcs pacemaker fence-agents-all
提示找不到软件包
No package pcs available.
No package pacemaker available.

baseurl需要修改
addons/HighAvailability/
addons/ResilientStorage/

yum —disablerepo=* —enablerepo=rhel-source* install pcs pacemaker fence-agents-all

4.yum安装

# yum clean all

# yum install cluster-glue resource-agents pacemaker

# yum install luci ricci cman openais rgmanager lvm2-cluster gfs2-utils

5.umount iso文件

umount /mnt

    需要完整的iso镜像，centos6.5有两个DVD镜像，将镜像放在相同目录下， 然后选择第一个安装即可 ![这里写图片描述][SouthEast] 否则会报错误：
