首先，把準(zhǔn)備的鏡像從網(wǎng)絡(luò)上下載或直接拷貝到/home/ecp2/mirror 目錄下（該目錄是根據(jù)該案例設(shè)定，可根據(jù)需要?jiǎng)?chuàng)建自己的文件目錄）

  1、sudo mkdir /home/ecp2/mirror        創(chuàng)建mirror目錄，把鏡像拷貝到mirror下

  2. sudo mkdir -p /media/CentOS         創(chuàng)建CentOS目錄，把磁盤.iso鏡像mount到CentOS目錄下

  3、sudo mount /dev/sr0 /media/CentOS   把iso安裝鏡像掛在到/media/CentOS 目錄下，該目錄是 /etc/yum.repos.d/CentOS-Media.repo 鏡像文件的baseurl默認(rèn)的第一個(gè)目錄

修改鏡像有效路徑: sudo vi /etc/yum.repos.d/CentOS-Media.repo

[ecp2@localhost root]$ sudo vi /etc/yum.repos.d/CentOS-Media.repo
# CentOS-Media.repo
#
# This repo can be used with mounted DVD media, verify the mount point for
# CentOS-7. 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=c7-media [command]
#
# or for ONLY the media repo, do this:
#
# yum --disablerepo=\* --enablerepo=c7-media [command]

[c7-media]
name=CentOS-$releasever - Media

       file:///media/cdrom/
       file:///media/cdrecorder/

gpgcheck=1
enabled=0
gpgkey=file:///etc/pki/rpm-gpg/RPM-GPG-KEY-CentOS-7          -------這塊新增的內(nèi)容，配置為本地鏡像home/ecp2/mirror/extras/x86_64 路徑下的鏡像， 數(shù)字簽名為etc/pki/rpm-gpg/RPM-GPG-KEY-CentOS-7

  4、sudo yum --disablerepo=\* --enablerepo=c7-media,offline-extras list | grep gluster  -----該命令是查看鏡像中的gluster中的鏡像 查看安裝gluster安裝的鏡像，如【centos-release-gluster38.noarch 】
  5、sudo yum --disablerepo=\* --enablerepo=c7-media,offline-extras install centos-release-gluster38.noarch ----該命令 安裝centos-release-gluster38.noarch

  5.1、 ls /etc/pki/rpm-gpg/                                  ------------查看pki-------多出來 RPM-GPG-KEY-CentOS-SIG-Storage
  5.2、 ls /home/ecp2/mirror/storage/x86_64/gluster-3.8       ------------新生成的鏡像

  6、sudo vi /etc/yum.repos.d/CentOS-Media.repo   ----修改鏡像配置
[ecp2@localhost root]$ vi /etc/yum.repos.d/CentOS-Media.repo

# CentOS-Media.repo
#
# This repo can be used with mounted DVD media, verify the mount point for
# CentOS-7. You can use this repo and yum to install items directly off the

gpgkey=file:///etc/pki/rpm-gpg/RPM-G                     ------這塊新增內(nèi)容配置鏡像home/ecp2/mirror/storage/x86_64/gluster-3.8 為之后安裝gluster，如【sudo yum install glusterfs-server glusterfs glusterfs-fuse】

 7、sudo yum --disablerepo=\* --enablerepo=c7-media,offline-extras,offline-storage-gluster38 list | grep glusterfs ---查看新配置的鏡像

 8、sudo yum --disablerepo=\* --enablerepo=c7-media,offline-extras,offline-storage-gluster38 install glusterfs-server glusterfs glusterfs-fuse -------安裝gluster環(huán)境 glusterfs-server glusterfs glusterfs-fuse

 9、sudo systemctl list-unit-files glusterd.service                       -----該命令查看gluster服務(wù)是否啟動(dòng)

 10、sudo systemctl enable glusterd.service && sudo systemctl start glusterd.service     ----sudo systemctl enable glusterd.service設(shè)置開機(jī)啟動(dòng)， sudo systemctl start glusterd.service

 11、sudo systemctl -l status glusterd.service   --查看gluster服務(wù)啟動(dòng)狀態(tài)

[ecp2@localhost x86_64]$ sudo systemctl -l status glusterd.service
