一、GFS部署
1.1.环境
Node1节点：node1/192.168.190.101 磁盘： /dev/sdb1 挂载点： /data/sdb1
/dev/sdc1 /data/sdc1
/dev/sdd1 /data/sdd1
/dev/sde1 /data/sde1
Node2节点：node2/192.168.190.105 磁盘： /dev/sdb1 挂载点： /data/sdb1
/dev/sdc1 /data/sdc1
/dev/sdd1 /data/sdd1
/dev/sde1 /data/sde1
Node3节点：node3/192.168.190.103 磁盘： /dev/sdb1 挂载点： /data/sdb1
/dev/sdc1 /data/sdc1
/dev/sdd1 /data/sdd1
/dev/sde1 /data/sde1
Node4节点：node4/192.168.190.104 磁盘： /dev/sdb1 挂载点： /data/sdb1
/dev/sdc1 /data/sdc1
/dev/sdd1 /data/sdd1
/dev/sde1 /data/sde1
=====客户端节点：192.168.190.102=====
1.2.更改节点名称
hostnamectl set-hostname node1
bash
hostnamectl set-hostname node2
bash
hostnamectl set-hostname node3
bash
hostnamectl set-hostname node4
bash1.3.节点进行磁盘挂载，安装本地源
1．关闭防火墙
[root@node1 ~] # systemctl stop firewalld
[root@node1 ~] # setenforce 0
2．磁盘分区，并挂载
[root@node1 ~] # vim /opt/fdisk.sh
#!/bin/bash
NEWDEV=`ls /dev/sd* | grep -o 'sd[b-z]' | uniq`
for VAR in $NEWDEV
do
echo -e "n\np\n\n\n\nw\n" | fdisk /dev/$VAR &> /dev/null
mkfs.xfs /dev/${VAR}"1" &> /dev/null
mkdir -p /data/${VAR}"1" &> /dev/null
echo "/dev/${VAR}"1" /data/${VAR}"1" xfs defaults 0 0" >> /etc/fstab
done
mount -a &> /dev/null
:wq
[root@node1 ~] # chmod +x /opt/fdisk.sh
[root@node1 ~] # cd /opt/
[root@node1 /opt] # ./fdisk.sh
3．修改主机名，配置/etc/hosts文件
[root@node1 /opt] # echo "192.168.190.101 node1" >> /etc/hosts
[root@node1 /opt] # echo "192.168.190.105 node2" >> /etc/hosts
[root@node1 /opt] # echo "192.168.190.103 node3" >> /etc/hosts
[root@node1 /opt] # echo "192.168.190.104 node4" >> /etc/hosts
[root@node1 /opt] # ls
fdisk.sh rh
[root@node1 /opt] # rz -E
rz waiting to receive.
[root@node1 /opt] # ls
fdisk.sh gfsrepo.zip rh
[root@node1 /opt] # unzip gfsrepo.zip
4. 安装、启动GlusterFS（所有node节点上操作）
[root@node1 /opt] # cd /etc/yum.repos.d/
[root@node1 /etc/yum.repos.d] # ls
local.repo repos.bak
[root@node1 /etc/yum.repos.d] # mv * repos.bak/
[root@node1 /etc/yum.repos.d] # ls
repos.bak
[root@node1 /etc/yum.repos.d] # vim glfs.repo
[glfs]
name=glfs
baseurl=file:///opt/gfsrepo
gpgcheck=0
enabled=1
:wq
[root@node1 /etc/yum.repos.d] # yum clean all && yum makecache
已加载插件：fastestmirror, langpacks
正在清理软件源： glfs
Cleaning up everything
Maybe you want: rm -rf /var/cache/yum, to also free up space taken by orphaned data from disabled or removed repos

1.4.添加节点创建集群
添加节点到存储信任池中（仅需在一个节点上操作，我这里依旧在node1节点上操作）
[root@node1 ~] # gluster peer probe node1
peer probe: success. Probe on localhost not needed
[root@node1 ~] # gluster peer probe node2
peer probe: success.
[root@node1 ~] # gluster peer probe node3
peer probe: success.
[root@node1 ~] # gluster peer probe node4
peer probe: success.

1.5.根据规划创建卷

1.6. 部署gluster客户端
部署Gluster客户端（192.168.190.102）
1．安装客户端软件
[root@promote ~]#systemctl stop firewalld
[root@promote ~]#setenforce 0
[root@promote ~]#cd /opt
[root@promote opt]#ls
rh
[root@promote opt]#rz -E
rz waiting to receive.
[root@promote opt]#ls
gfsrepo.zip rh
[root@promote opt]#unzip gfsrepo.zip
[root@promote opt]#cd /etc/yum.repos.d/
[root@promote yum.repos.d]#ls
local.repo repos.bak
[root@promote yum.repos.d]#mv *.repo repos.bak/
[root@promote yum.repos.d]#ls
repos.bak
[root@promote yum.repos.d]#vim glfs.repo
[glfs]
name=glfs
baseurl=file:///opt/gfsrepo
gpgcheck=0
enabled=1
[root@promote yum.repos.d]#yum clean all && yum makecache
[root@promote yum.repos.d]#yum -y install glusterfs glusterfs-fuse
2．创建挂载目录
[root@promote yum.repos.d]# mkdir -p /test/{fengbushi,fenbushi-tiaodai,fbs-fz,tiaodaijun,fuzhi}
[root@localhost test]# ls
fbs-fz fengbushi tiaodaijun fenbushi-tiaodai fuzhi
3．配置 /etc/hosts 文件
[root@localhost test]# echo "192.168.190.101 node1" >> /etc/hosts
[root@localhost test]# echo "192.168.190.105 node2" >> /etc/hosts
[root@localhost test]# echo "192.168.190.103 node3" >> /etc/hosts
[root@localhost test]# echo "192.168.190.104 node4" >> /etc/hosts
4．挂载 Gluster 文件系统
#临时挂载
[root@localhost test]# mount.glusterfs node1:fbs-fz /test/fbs-fz
[root@localhost test]# mount.glusterfs node1:tiaodaijun /test/tiaodaijun/
[root@localhost test]# mount.glusterfs node1:fuzhi /test/fuzhi/
[root@localhost test]# mount.glusterfs node1:fenbushi-tiaodai /test/fenbushi-tiaodai/
[root@localhost test]# mount.glusterfs node1:fenbushi /test/fengbushi/
[root@localhost test]# df -h

1.7.测试 Gluster 文件系统
1．卷中写入文件，客户端操作
cd /opt
dd if=/dev/zero of=/opt/demo1.log bs=1M count=40
dd if=/dev/zero of=/opt/demo2.log bs=1M count=40
dd if=/dev/zero of=/opt/demo3.log bs=1M count=40
dd if=/dev/zero of=/opt/demo4.log bs=1M count=40
dd if=/dev/zero of=/opt/demo5.log bs=1M count=40
ls -lh /opt
cp /opt/demo* /test/fengbushi/
cp /opt/demo* /test/fenbushi-tiaodai/
cp /opt/demo* /test/fuzhi/
cp /opt/demo* /test/fbs-fz/
cp /opt/demo* /test/tiaodaijun/
查看分布式文件分布
查看条带卷文件分布
查看复制卷分布
查看分布式条带卷分布
查看分布式复制卷分布
1.7. 破坏性测试
挂起 node2 节点或者关闭glusterd服务来模拟故障
[root@node2 ~]# systemctl stop glusterd.service
条带卷，无法访问，不具备冗余
复制卷，在node3和node4上的，关闭node4
[root@node4 ~]#init 0
客户端，仍然存在 
分布式复制卷，具有冗余
带有复制数据的，数据都比较安全
