首先，把准备的镜像从网络上下载或直接拷贝到/home/ecp2/mirror 目录下（该目录是根据该案例设定，可根据需要创建自己的文件目录）

  1、sudo mkdir /home/ecp2/mirror        创建mirror目录，把镜像拷贝到mirror下

  2. sudo mkdir -p /media/CentOS         创建CentOS目录，把磁盘.iso镜像mount到CentOS目录下

  3、sudo mount /dev/sr0 /media/CentOS   把iso安装镜像挂在到/media/CentOS 目录下，该目录是 /etc/yum.repos.d/CentOS-Media.repo 镜像文件的baseurl默认的第一个目录

修改镜像有效路径: 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
baseurl=file:///media/CentOS/
       file:///media/cdrom/
       file:///media/cdrecorder/
gpgcheck=1
enabled=0
gpgkey=file:///etc/pki/rpm-gpg/RPM-GPG-KEY-CentOS-7

[offline-extras]
name=CentOS-$releasever - Media
baseurl=file:///home/ecp2/mirror/extras/x86_64
gpgcheck=1
enabled=0
gpgkey=file:///etc/pki/rpm-gpg/RPM-GPG-KEY-CentOS-7          -------这块新增的内容，配置为本地镜像home/ecp2/mirror/extras/x86_64 路径下的镜像， 数字签名为etc/pki/rpm-gpg/RPM-GPG-KEY-CentOS-7

  4、sudo yum --disablerepo=\* --enablerepo=c7-media,offline-extras list | grep gluster  -----该命令是查看镜像中的gluster中的镜像 查看安装gluster安装的镜像，如【centos-release-gluster38.noarch 】
  5、sudo yum --disablerepo=\* --enablerepo=c7-media,offline-extras install centos-release-gluster38.noarch ----该命令 安装centos-release-gluster38.noarch

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

  6、sudo vi /etc/yum.repos.d/CentOS-Media.repo   ----修改镜像配置
[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
# 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
baseurl=file:///media/CentOS/
       file:///media/cdrom/
       file:///media/cdrecorder/
gpgcheck=1
enabled=0
gpgkey=file:///etc/pki/rpm-gpg/RPM-GPG-KEY-CentOS-7

[offline-extras]
name=CentOS-$releasever - Media
baseurl=file:///home/ecp2/mirror/extras/x86_64
gpgcheck=1
enabled=0
gpgkey=file:///etc/pki/rpm-gpg/RPM-GPG-KEY-CentOS-7

[offline-storage-gluster38]
name=CentOS-$releasever - Media
baseurl=file:///home/ecp2/mirror/storage/x86_64/gluster-3.8
gpgcheck=1
enabled=0
gpgkey=file:///etc/pki/rpm-gpg/RPM-G                     ------这块新增内容配置镜像home/ecp2/mirror/storage/x86_64/gluster-3.8 为之后安装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 ---查看新配置的镜像

 8、sudo yum --disablerepo=\* --enablerepo=c7-media,offline-extras,offline-storage-gluster38 install glusterfs-server glusterfs glusterfs-fuse -------安装gluster环境 glusterfs-server glusterfs glusterfs-fuse

 9、sudo systemctl list-unit-files glusterd.service                       -----该命令查看gluster服务是否启动

 10、sudo systemctl enable glusterd.service && sudo systemctl start glusterd.service     ----sudo systemctl enable glusterd.service设置开机启动， sudo systemctl start glusterd.service

 11、sudo systemctl -l status glusterd.service   --查看gluster服务启动状态

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