一、GlusterFS基础环境的介绍
1、关于GlusterFS文件系统和架构的介绍
http://jingyan.baidu.com/article/046a7b3ef65250f9c27fa9d9.html
2、实验的目的
a. 利用多台性能较低并且老旧的服务器，实现企业的云盘功能
b. GlusterFS服务端和客户端的部署和配置
c. 实现GlusterFS多节点的负载均衡功能
3、测试环境说明
操作系统：CentOS 6.7 X64
内核版本：2.6.32-573.el6.x86_64
软件版本：glusterfs 3.7.10
使用4台服务器创卷GlusterFS的DHT功能，客户端win10使用samba进行连接配置
二、GlusterFS服务端的配置（server01）
1、GlusterFS无中心化概念，很多关于GlusterFS的配置仅需要在其中一台主机设置
2、配置NTP服务器同步（这里也可以在crontab脚本里面，添加一个定时任务）
[[email protected] ~]# ntpdate -u 10.203.10.20 18 Apr 14:16:15 ntpdate[2700]: adjust time server 10.203.10.20 offset 0.008930 sec [[email protected] ~]# hwclock -w
3、查看hosts表的记录
[[email protected] ~]# cat /etc/hosts 127.0.0.1 localhost localhost.localdomain localhost4 localhost4.localdomain4 ::1 localhost localhost.localdomain localhost6 localhost6.localdomain6 192.168.1.11server01 192.168.1.12server02 192.168.1.13server03 192.168.1.14server04
4、单独添加一块磁盘作为共享卷使用（这里也可以配置LVM）
[[email protected] ~]# fdisk /dev/sdb
Device contains neither a valid DOS partition table, nor Sun, SGI or OSF disklabel
Building a new DOS disklabel with disk identifier 0x0ef88f22.
Changes will remain in memory only, until you decide to write them.
After that, of course, the previous content won‘t be recoverable.
Warning: invalid flag 0x0000 of partition table 4 will be corrected by w(rite)
WARNING: DOS-compatible mode is deprecated. It‘s strongly recommended to
switch off the mode (command ‘c‘) and change display units to
sectors (command ‘u‘).

5、创建挂载目录，并设置开机挂载
[[email protected] ~]# mkdir -p /glusterfs-xfs-mount [[email protected] ~]# mount /dev/sdb1 /glusterfs-xfs-mount/ [[email protected] ~]# df -h Filesystem Size Used Avail Use% Mounted on /dev/sda3 193G 7.2G 176G 4% / tmpfs 932M 0 932M 0% /dev/shm /dev/sda1 190M 41M 139M 23% /boot /dev/sdb1 20G 44M 19G 1% /glusterfs-xfs-mount
6、修改自动挂载
[[email protected] ~]# echo ‘/dev/sdb1 /glusterfs-xfs-mount xfs defaults 0 0‘ >> /etc/fstab
7、添加外部源
[[email protected] ~]# cd /etc/yum.repos.d/ [[email protected] yum.repos.d]# wget http://download.gluster.org/pub/gluster/glusterfs/LATEST/CentOS/glusterfs-epel.repo
8、安装glusterfs服务端软件，并启动服务
[[email protected] yum.repos.d]# yum -y install glusterfs-server [[email protected] yum.repos.d]# /etc/init.d/glusterd start Starting glusterd: [ OK ] [[email protected] yum.repos.d]# chkconfig glusterd on [[email protected] yum.repos.d]# chkconfig --list glusterd glusterd 0:off1:off2:on3:on4:on5:on6:off [[email protected] yum.repos.d]# df -h Filesystem Size Used Avail Use% Mounted on /dev/sda3 193G 7.2G 176G 4% / tmpfs 932M 0 932M 0% /dev/shm /dev/sda1 190M 41M 139M 23% /boot /dev/sdb1 20G 44M 19G 1% /glusterfs-xfs-mount
9、添加集群对象（server02以及server03）
[[email protected] yum.repos.d]# gluster peer status Number of Peers: 0 [[email protected] yum.repos.d]# gluster peer probe server02 peer probe: success. [[email protected] yum.repos.d]# gluster peer status Number of Peers: 1 Hostname: server02 Uuid: c58d0715-32ff-4962-90d9-4275fa65793a State: Peer in Cluster (Connected) [[email protected] yum.repos.d]# gluster peer probe server03 peer probe: success. [[email protected] yum.repos.d]# gluster peer status Number of Peers: 2 Hostname: server02 Uuid: c58d0715-32ff-4962-90d9-4275fa65793a State: Peer in Cluster (Connected) Hostname: server03 Uuid: 5110d0af-fdd9-4c82-b716-991cf0601b53 State: Peer in Cluster (Connected)
10、创建Gluster Volume
[[email protected] yum.repos.d]# gluster volume create dht-volume01 server01:/glusterfs-xfs-mount server02:/gluste rfs-xfs-mount server03:/glusterfs-xfs-mount volume create: dht-volume01: failed: The brick server01:/glusterfs-xfs-mount is a mount point. Please create a sub-directory under the mount point and use that as the brick directory. Or use ‘force‘ at the end of the com mand if you want to override this behavior. [[email protected] yum.repos.d]# echo $? 1 [[email protected] yum.repos.d]# gluster volume create dht-volume01 server01:/glusterfs-xfs-mount server02:/gluste rfs-xfs-mount server03:/glusterfs-xfs-mount force volume create: dht-volume01: success: please start the volume to access data [[email protected] yum.repos.d]# gluster volume start dht-volume01 volume start: dht-volume01: success [[email protected] yum.repos.d]# gluster volume status Status of volume: dht-volume01 Gluster process TCP Port RDMA Port Online Pid ------------------------------------------------------------------------------ Brick server01:/glusterfs-xfs-mount 49152 0 Y 2948 Brick server02:/glusterfs-xfs-mount 49152 0 Y 2910 Brick server03:/glusterfs-xfs-mount 49152 0 Y 11966 NFS Server on localhost N/A N/A N N/A NFS Server on server02 N/A N/A N N/A NFS Server on server03 N/A N/A N N/A Task Status of Volume dht-volume01 ------------------------------------------------------------------------------ There are no active volume tasks
11、测试写入一个512M的文件
[[email protected] yum.repos.d]# cd /glusterfs-xfs-mount/ [[email protected] glusterfs-xfs-mount]# dd if=/dev/zero of=test.img bs=1M count=512 512+0 records in 512+0 records out 536870912 bytes (537 MB) copied, 5.20376 s, 103 MB/s [[email protected] glusterfs-xfs-mount]# ls lost+found test.img
三、GlusterFS服务端的配置（server02与server03上的配置类似）
1、配置时间同步，这里的ntp服务器IP地址为10.203.10.20
[[email protected] ~]# ntpdate -u 10.203.10.20 18 Apr 14:27:58 ntpdate[2712]: adjust time server 10.203.10.20 offset -0.085282 sec [[email protected] ~]# hwclock -w
2、查看host表的信息
[[email protected] ~]# cat /etc/hosts 127.0.0.1 localhost localhost.localdomain localhost4 localhost4.localdomain4 ::1 localhost localhost.localdomain localhost6 localhost6.localdomain6 192.168.1.11server01 192.168.1.12server02 192.168.1.13server03 192.168.1.14server04
3、在本地设置一块单独的盘，组成GlusterFS卷的一部分
[[email protected] ~]# fdisk /dev/sdb
Device contains neither a valid DOS partition table, nor Sun, SGI or OSF disklabel
Building a new DOS disklabel with disk identifier 0x927b5e72.
Changes will remain in memory only, until you decide to write them.
After that, of course, the previous content won‘t be recoverable.
Warning: invalid flag 0x0000 of partition table 4 will be corrected by w(rite)

4、更新磁盘分区表信息，使磁盘分区和格式化
[[email protected] ~]# partx /dev/sdb # 1: 63- 41929649 ( 41929587 sectors, 21467 MB) # 2: 0- -1 ( 0 sectors, 0 MB) # 3: 0- -1 ( 0 sectors, 0 MB) # 4: 0- -1 ( 0 sectors, 0 MB) [[email protected] ~]# fdisk -l|grep /dev/sdb Disk /dev/sdb: 21.5 GB, 21474836480 bytes /dev/sdb1 1 2610 20964793+ 83 Linux [[email protected] ~]# mkfs.ext4 /dev/sdb1 mke2fs 1.41.12 (17-May-2010) Filesystem label= OS type: Linux Block size=4096 (log=2) Fragment size=4096 (log=2) Stride=0 blocks, Stripe width=0 blocks 1310720 inodes, 5241198 blocks 262059 blocks (5.00%) reserved for the super user First data block=0 Maximum filesystem blocks=4294967296 160 block groups 32768 blocks per group, 32768 fragments per group 8192 inodes per group Superblock backups stored on blocks: 32768, 98304, 163840, 229376, 294912, 819200, 884736, 1605632, 2654208, 4096000 Writing inode tables: done Creating journal (32768 blocks): done Writing superblocks and filesystem accounting information: done This filesystem will be automatically checked every 21 mounts or 180 days, whichever comes first. Use tune2fs -c or -i to override. [[email protected] ~]# df -h Filesystem Size Used Avail Use% Mounted on /dev/sda3 193G 7.3G 176G 4% / tmpfs 932M 0 932M 0% /dev/shm /dev/sda1 190M 41M 139M 23% /boot
5、创建挂载目录，并配置挂载信息
[[email protected] ~]# mkdir -p /glusterfs-xfs-mount [[email protected] ~]# mount /dev/sdb1 /glusterfs-xfs-mount/ [[email protected] ~]# df -h Filesystem Size Used Avail Use% Mounted on /dev/sda3 193G 7.3G 176G 4% / tmpfs 932M 0 932M 0% /dev/shm /dev/sda1 190M 41M 139M 23% /boot /dev/sdb1 20G 44M 19G 1% /glusterfs-xfs-mount [[email protected] ~]# echo ‘/dev/sdb1 /glusterfs-xfs-mount xfs defaults 0 0‘ >> /etc/fstab
6、配置yum源，并安装GlusterFS服务端软件
[[email protected] ~]# cd /etc/yum.repos.d/ [[email protected] yum.repos.d]# wget http://download.gluster.org/pub/gluster/glusterfs/LATEST/CentOS/glust erfs-epel.repo --2016-04-18 14:32:22-- http://download.gluster.org/pub/gluster/glusterfs/LATEST/CentOS/glusterfs-epel. repo Resolving download.gluster.org... 23.253.208.221, 2001:4801:7824:104:be76:4eff:fe10:23d8 Connecting to download.gluster.org|23.253.208.221|:80... connected.

7、启动glusterd服务
[[email protected] yum.repos.d]# /etc/init.d/glusterd start Starting glusterd: [ OK ] [[email protected] yum.repos.d]# chkconfig glusterd on [[email protected] yum.repos.d]# chkconfig --list glusterd glusterd 0:off1:off2:on3:on4:on5:on6:off
8、查看gluster集群节点和卷的信息
[[email protected] yum.repos.d]# gluster peer status Number of Peers: 1 Hostname: server01 Uuid: e90a3b54-5a9d-4e57-b502-86f9aad8b576 State: Peer in Cluster (Connected) [[email protected] yum.repos.d]# gluster volume status Status of volume: dht-volume01 Gluster process TCP Port RDMA Port Online Pid ------------------------------------------------------------------------------ Brick server01:/glusterfs-xfs-mount 49152 0 Y 2948 Brick server02:/glusterfs-xfs-mount 49152 0 Y 2910 Brick server03:/glusterfs-xfs-mount 49152 0 Y 11966 NFS Server on localhost 2049 0 Y 2932 NFS Server on server01 2049 0 Y 2968 NFS Server on server03 2049 0 Y 11986 Task Status of Volume dht-volume01 ------------------------------------------------------------------------------ There are no active volume tasks [[email protected] yum.repos.d]# ll /glusterfs-xfs-mount/ total 16 drwx------ 2 root root 16384 Apr 18 14:29 lost+found [[email protected] yum.repos.d]# cd /glusterfs-xfs-mount/ [[email protected] glusterfs-xfs-mount]# dd if=/dev/zero of=server02.img bs=1M count=512 512+0 records in 512+0 records out 536870912 bytes (537 MB) copied, 5.85478 s, 91.7 MB/s [[email protected] glusterfs-xfs-mount]# ls lost+found server02.img
由于我这里配置的是DHT的模式，所以集群在server01与server02的数据信息是不同的，除非人为写入相同文件
四、手动添加和删除brick卷的卷节点的信息（任意一个gluster服务端节点上的操作都可以）
1、添加server04节点
[[email protected] glusterfs-xfs-mount]# gluster peer probe server04 peer probe: success. [[email protected] glusterfs-xfs-mount]# gluster peer status Number of Peers: 3 Hostname: server02 Uuid: c58d0715-32ff-4962-90d9-4275fa65793a State: Peer in Cluster (Connected) Hostname: server03 Uuid: 5110d0af-fdd9-4c82-b716-991cf0601b53 State: Peer in Cluster (Connected) Hostname: server04 Uuid: d653b5c2-dac4-428c-bf6f-eea393adbb16 State: Peer in Cluster (Connected)
2、添加一个节点卷的信息到dht-volume的brick中
[[email protected] glusterfs-xfs-mount]# gluster volume add-brick Usage: volume add-brick <VOLNAME> [<stripe|replica> <COUNT>] <NEW-BRICK> ... [force] [[email protected] glusterfs-xfs-mount]# gluster volume add-brick dht-volume01 server04:/glusterfs-xfs-mount volume add-brick: failed: Pre Validation failed on server04. The brick server04:/glusterfs-xfs-mount is a moun t point. Please create a sub-directory under the mount point and use that as the brick directory. Or use ‘forc e‘ at the end of the command if you want to override this behavior. [[email protected] glusterfs-xfs-mount]# gluster volume add-brick dht-volume01 server04:/glusterfs-xfs-mount force volume add-brick: success [[email protected] glusterfs-xfs-mount]# gluster volume status Status of volume: dht-volume01 Gluster process TCP Port RDMA Port Online Pid ------------------------------------------------------------------------------ Brick server01:/glusterfs-xfs-mount 49152 0 Y 2948 Brick server02:/glusterfs-xfs-mount 49152 0 Y 2910 Brick server03:/glusterfs-xfs-mount 49152 0 Y 11966 Brick server04:/glusterfs-xfs-mount 49152 0 Y 2925 NFS Server on localhost 2049 0 Y 3258 NFS Server on server02 2049 0 Y 3107 NFS Server on server03 2049 0 Y 12284 NFS Server on server04 2049 0 Y 2945 Task Status of Volume dht-volume01 ------------------------------------------------------------------------------ There are no active volume tasks
3、从brick中移除一个节点卷
[[email protected] ~]# gluster volume remove-brick dht-volume01 server04:/glusterfs-xfs-mount/ Usage: volume remove-brick <VOLNAME> [replica <COUNT>] <BRICK> ... <start|stop|status|commit|force> [[email protected] ~]# gluster volume remove-brick dht-volume01 server04:/glusterfs-xfs-mount/ commit Removing brick(s) can result in data loss. Do you want to Continue? (y/n) y volume remove-brick commit: success Check the removed bricks to ensure all files are migrated. If files with data are found on the brick path, copy them via a gluster mount point before re-purposing the re moved brick. [[email protected] ~]# gluster volume status Status of volume: dht-volume01 Gluster process TCP Port RDMA Port Online Pid ------------------------------------------------------------------------------ Brick server01:/glusterfs-xfs-mount 49152 0 Y 2948 Brick server02:/glusterfs-xfs-mount 49152 0 Y 2910 Brick server03:/glusterfs-xfs-mount 49152 0 Y 11966 NFS Server on localhost 2049 0 Y 3336 NFS Server on server02 2049 0 Y 3146 NFS Server on server04 2049 0 Y 2991 NFS Server on server03 2049 0 Y 12323 Task Status of Volume dht-volume01 ------------------------------------------------------------------------------ There are no active volume tasks
五、配置均衡分布（rebalance）
[[email protected] ~]# gluster volume rebalance dht-volume01
Usage: volume rebalance <VOLNAME> {{fix-layout start} | {start [force]|stop|status}}
[[email protected] ~]# gluster volume rebalance dht-volume01 fix-layout start
volume rebalance: dht-volume01: success: Rebalance on dht-volume01 has been started successfully. Use rebalanc
e status command to check status of the rebalance process.
