Server Role | IP addresses | disk space |
|---|---|---|---|
| gfs-node1 | 192.168.142.152 | 40G+40G | |
| gfs-node2 | 192.168.142.154 | 40G+40G | |
| gfs-node3 | 192.168.142.162 | 40G+40G | |

| kvm-client | 192.168.142.163 | 40G |
The first step: GFS node server deployment
1. Four GFS node server for each server to add a new disk
2. Use a script to deploy GFS key node
#!/bin/bash
systemctl stop firewalld.service
setenforce 0
#格式化磁盘
echo "the disks exist list:"
fdisk -l |grep '磁盘 /dev/sd[a-z]'
echo "=================================================="
PS3="chose which disk you want to create:"
select VAR in `ls /dev/sd*|grep -o 'sd[b-z]'|uniq` quit
do
case $VAR in
sda)
fdisk -l /dev/sda
break ;;
sd[b-z])
#create partitions
echo "n
p
w" | fdisk /dev/$VAR
#make filesystem
mkfs.xfs -i size=512 /dev/${VAR}"1" &> /dev/null
#mount the system
mkdir -p /data/${VAR}"1" &> /dev/null
echo -e "/dev/${VAR}"1" /data/${VAR}"1" xfs defaults 0 0\n" >> /etc/fstab
mount -a &> /dev/null
break ;;
quit)
break;;
*)
echo "wrong disk,please check again";;

3. deployed four nodes, node operations on node1
#添加其他节点信息
gluster peer probe node2
gluster peer probe node3
gluster peer probe node4
#创建分布式卷
gluster volume create dis-volume replica 2 node1:/data/sdb1 node2:/data/sdb1 node3:/data/sdb1 node4:/data/sdb1 force
#启动分布式卷
gluster volume start dis-volumeStep two: KVM client deployment operations
1. debugging client environment, the least memory 4G, open virtualization engine 
2. Mount the GFS to the client
#创建挂载目录
mkdir /data
#挂载分布式卷到客户端目录
mount.glusterfs node1:dis-vol /data
#查看磁盘分区信息
df -hT
#远程挂载微软宿主机上的镜像,后面再用

#查看CPU是否支持虚拟化(虚拟机需要配置中开启虚拟化功能)
egrep '(vmx|svm)' /proc/cpuinfo
#查看kvm模块是否安装
lsmod | grep kvm
#开启libvirtd服务
systemctl start libvirtd
#查看libvirtd服务状态

1. Open a terminal and type the following command as root switch graphical management interface
#打开终端输入一下命令切换图形化管理界面
virt-manager2. Create the deployment of virtualized environments
创建存储池，双击QEMU/KVM，选择“存储”选项卡，然后单击“+”按钮新建存储池。
单击“前进”按钮，根据提示输入或浏览用以设置存储目录，如/data_kvm/store,最后单击“完成”按钮即可
