Linux下安裝lvs

lvs已經編譯到linux內核中，僅僅須要安裝lvs的管理軟件ipvsadm就可以
1. 插入光盤。查找設備

[root@chen ~]# ls -l /dev | grep cdrom
lrwxrwxrwx. 1 root root           3 12月 28 07:29 cdrom -> sr0
crw-rw----. 1 root cdrom    21,   1 12月 28 07:29 sg1
brw-rw----. 1 root cdrom    11,   0 12月 28 07:29 sr0

2. 載入光驅

[root@chen ~]# mount /dev/cdrom /mnt
mount: block device /dev/sr0 is write-protected, mounting read-only

3. 配置倉庫
vi /etc/yum.repos.d/CentOS-Media.repo
改動前

# CentOS-Media.repo
#
#  This repo can be used with mounted DVD media, verify the mount point for
#  CentOS-6.  You can use this repo and yum to install items directly off the
#  DVD ISO that we release.
#
# To use this repo, put in your DVD and use it with the other repos too:
#  yum --enablerepo=c6-media [command]
#
# or for ONLY the media repo, do this:
#
#  yum --disablerepo=\* --enablerepo=c6-media [command]
[c6-media]
name=CentOS-$releasever - Media
baseurl=file:///media/CentOS/
        file:///media/cdrom/
        file:///media/cdrecorder/
gpgcheck=1
enabled=0
gpgkey=file:///etc/pki/rpm-gpg/RPM-GPG-KEY-CentOS-6

改動后

# CentOS-Media.repo
#
#  This repo can be used with mounted DVD media, verify the mount point for
#  CentOS-6.  You can use this repo and yum to install items directly off the
#  DVD ISO that we release.
#
# To use this repo, put in your DVD and use it with the other repos too:
#  yum --enablerepo=c6-media [command]
#
# or for ONLY the media repo, do this:
#
#  yum --disablerepo=\* --enablerepo=c6-media [command]
[c6-media]
name=CentOS-$releasever - Media
baseurl=file:///media/CentOS/
        file:///media/cdrom/
        file:///media/cdrecorder/
gpgcheck=1
enabled=0
gpgkey=file:///etc/pki/rpm-gpg/RPM-GPG-KEY-CentOS-6

4. 安裝ipvsadm

[root@chen ~]# yum --disablerepo=\* --enablerepo=c6-media install ipvsadm
