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)
[root@server01 ~]# ntpdate -u 10.203.10.2018 Apr 14:16:15 ntpdate[2700]: adjust time server 10.203.10.20 offset 0.008930 sec[root@server01 ~]# hwclock -w
3、查看hosts表的记录
[root@server01 ~]# cat /etc/hosts127.0.0.1 localhost localhost.localdomain localhost4 localhost4.localdomain4::1 localhost localhost.localdomain localhost6 localhost6.localdomain6192.168.1.11server01192.168.1.12server02192.168.1.13server03192.168.1.14server04
4、单独添加一块磁盘作为共享卷使用(这里也可以配置LVM)
[root@server01 ~]# fdisk /dev/sdbDevice contains neither a valid DOS partition table, nor Sun, SGI or OSF disklabelBuilding 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').Command (m for help): pDisk /dev/sdb: 21.5 GB, 21474836480 bytes255 heads, 63 sectors/track, 2610 cylindersUnits = cylinders of 16065 * 512 = 8225280 bytesSector size (logical/physical): 512 bytes / 512 bytesI/O size (minimum/optimal): 512 bytes / 512 bytesDisk identifier: 0x0ef88f22 Device Boot Start End Blocks Id SystemCommand (m for help): nCommand action e extended p primary partition (1-4)pPartition number (1-4): 1First cylinder (1-2610, default 1): Using default value 1Last cylinder, +cylinders or +size{K,M,G} (1-2610, default 2610): Using default value 2610Command (m for help): wThe partition table has been altered!Calling ioctl() to re-read partition table.Syncing disks.[root@server01 ~]# 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)[root@server01 ~]# fdisk -l |grep /dev/sdbDisk /dev/sdb: 21.5 GB, 21474836480 bytes/dev/sdb1 1 2610 20964793+ 83 Linux[root@server01 ~]# mkfs.ext4 /dev/sdb1mke2fs 1.41.12 (17-May-2010)Filesystem label=OS type: LinuxBlock size=4096 (log=2)Fragment size=4096 (log=2)Stride=0 blocks, Stripe width=0 blocks1310720 inodes, 5241198 blocks262059 blocks (5.00%) reserved for the super userFirst data block=0Maximum filesystem blocks=4294967296160 block groups32768 blocks per group, 32768 fragments per group8192 inodes per groupSuperblock backups stored on blocks: 32768, 98304, 163840, 229376, 294912, 819200, 884736, 1605632, 2654208, 4096000Writing inode tables: done Creating journal (32768 blocks): doneWriting superblocks and filesystem accounting information: doneThis filesystem will be automatically checked every 36 mounts or180 days, whichever comes first. Use tune2fs -c or -i to override.
5、创建挂载目录,并设置开机挂载
[root@server01 ~]# mkdir -p /glusterfs-xfs-mount[root@server01 ~]# mount /dev/sdb1 /glusterfs-xfs-mount/[root@server01 ~]# df -hFilesystem 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
[root@server01 ~]# echo '/dev/sdb1 /glusterfs-xfs-mount xfs defaults 0 0' >> /etc/fstab
7、添加外部源
[root@server01 ~]# cd /etc/yum.repos.d/[root@server01 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
[root@server01 yum.repos.d]# yum -y install glusterfs-server[root@server01 yum.repos.d]# /etc/init.d/glusterd startStarting glusterd: [ OK ][root@server01 yum.repos.d]# chkconfig glusterd on[root@server01 yum.repos.d]# chkconfig --list glusterdglusterd 0:off1:off2:on3:on4:on5:on6:off[root@server01 yum.repos.d]# df -hFilesystem 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)
[root@server01 yum.repos.d]# gluster peer statusNumber of Peers: 0[root@server01 yum.repos.d]# gluster peer probe server02peer probe: success. [root@server01 yum.repos.d]# gluster peer statusNumber of Peers: 1Hostname: server02Uuid: c58d0715-32ff-4962-90d9-4275fa65793aState: Peer in Cluster (Connected)[root@server01 yum.repos.d]# gluster peer probe server03peer probe: success. [root@server01 yum.repos.d]# gluster peer statusNumber of Peers: 2Hostname: server02Uuid: c58d0715-32ff-4962-90d9-4275fa65793aState: Peer in Cluster (Connected)Hostname: server03Uuid: 5110d0af-fdd9-4c82-b716-991cf0601b53State: Peer in Cluster (Connected)
10、创建Gluster Volume
[root@server01 yum.repos.d]# gluster volume create dht-volume01 server01:/glusterfs-xfs-mount server02:/glusterfs-xfs-mount server03:/glusterfs-xfs-mountvolume 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 command if you want to override this behavior.[root@server01 yum.repos.d]# echo $?1[root@server01 yum.repos.d]# gluster volume create dht-volume01 server01:/glusterfs-xfs-mount server02:/glusterfs-xfs-mount server03:/glusterfs-xfs-mount forcevolume create: dht-volume01: success: please start the volume to access data[root@server01 yum.repos.d]# gluster volume start dht-volume01volume start: dht-volume01: success[root@server01 yum.repos.d]# gluster volume statusStatus of volume: dht-volume01Gluster 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 11966NFS 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
[root@server01 yum.repos.d]# cd /glusterfs-xfs-mount/[root@server01 glusterfs-xfs-mount]# dd if=/dev/zero of=test.img bs=1M count=512512+0 records in512+0 records out536870912 bytes (537 MB) copied, 5.20376 s, 103 MB/s[root@server01 glusterfs-xfs-mount]# lslost+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
[root@server02 ~]# ntpdate -u 10.203.10.2018 Apr 14:27:58 ntpdate[2712]: adjust time server 10.203.10.20 offset -0.085282 sec[root@server02 ~]# hwclock -w
2、查看host表的信息
[root@server02 ~]# cat /etc/hosts127.0.0.1 localhost localhost.localdomain localhost4 localhost4.localdomain4::1 localhost localhost.localdomain localhost6 localhost6.localdomain6192.168.1.11server01192.168.1.12server02192.168.1.13server03192.168.1.14server04
3、在本地设置一块单独的盘,组成GlusterFS卷的一部分
[root@server02 ~]# fdisk /dev/sdbDevice contains neither a valid DOS partition table, nor Sun, SGI or OSF disklabelBuilding 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)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').Command (m for help): pDisk /dev/sdb: 21.5 GB, 21474836480 bytes255 heads, 63 sectors/track, 2610 cylindersUnits = cylinders of 16065 * 512 = 8225280 bytesSector size (logical/physical): 512 bytes / 512 bytesI/O size (minimum/optimal): 512 bytes / 512 bytesDisk identifier: 0x927b5e72 Device Boot Start End Blocks Id SystemCommand (m for help): nCommand action e extended p primary partition (1-4)pPartition number (1-4): 1First cylinder (1-2610, default 1): Using default value 1Last cylinder, +cylinders or +size{K,M,G} (1-2610, default 2610): Using default value 2610Command (m for help): wThe partition table has been altered!Calling ioctl() to re-read partition table.Syncing disks.
4、更新磁盘分区表信息,使磁盘分区和格式化
[root@server02 ~]# 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)[root@server02 ~]# fdisk -l|grep /dev/sdbDisk /dev/sdb: 21.5 GB, 21474836480 bytes/dev/sdb1 1 2610 20964793+ 83 Linux[root@server02 ~]# mkfs.ext4 /dev/sdb1mke2fs 1.41.12 (17-May-2010)Filesystem label=OS type: LinuxBlock size=4096 (log=2)Fragment size=4096 (log=2)Stride=0 blocks, Stripe width=0 blocks1310720 inodes, 5241198 blocks262059 blocks (5.00%) reserved for the super userFirst data block=0Maximum filesystem blocks=4294967296160 block groups32768 blocks per group, 32768 fragments per group8192 inodes per groupSuperblock backups stored on blocks: 32768, 98304, 163840, 229376, 294912, 819200, 884736, 1605632, 2654208, 4096000Writing inode tables: done Creating journal (32768 blocks): doneWriting superblocks and filesystem accounting information: doneThis filesystem will be automatically checked every 21 mounts or180 days, whichever comes first. Use tune2fs -c or -i to override.[root@server02 ~]# df -hFilesystem 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
[root@server02 ~]# mkdir -p /glusterfs-xfs-mount[root@server02 ~]# mount /dev/sdb1 /glusterfs-xfs-mount/[root@server02 ~]# df -hFilesystem 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[root@server02 ~]# 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
[root@server02 ~]# cd /etc/yum.repos.d/[root@server02 yum.repos.d]# wget http://download.gluster.org/pub/gluster/glusterfs/LATEST/CentOS/glusterfs-epel.repo--2016-04-18 14:32:22-- http://download.gluster.org/pub/gluster/glusterfs/LATEST/CentOS/glusterfs-epel.repoResolving download.gluster.org... 23.253.208.221, 2001:4801:7824:104:be76:4eff:fe10:23d8Connecting to download.gluster.org|23.253.208.221|:80... connected.HTTP request sent, awaiting response... 200 OKLength: 1049 (1.0K)Saving to: “glusterfs-epel.repo”100%[==============================================================>] 1,049 --.-K/s in 0s 2016-04-18 14:32:23 (36.4 MB/s) - “glusterfs-epel.repo” saved [1049/1049][root@server02 yum.repos.d]# rpm -ivh http://dl.fedoraproject.org/pub/epel/6/x86_64/epel-release-6-8.noarch.rpmRetrieving http://dl.fedoraproject.org/pub/epel/6/x86_64/epel-release-6-8.noarch.rpmwarning: /var/tmp/rpm-tmp.gaJCKd: Header V3 RSA/SHA256 Signature, key ID 0608b895: NOKEYPreparing... ########################################### [100%] 1:epel-release ########################################### [100%][root@server02 yum.repos.d]# yum -y install glusterfs-server
7、启动glusterd服务
[root@server02 yum.repos.d]# /etc/init.d/glusterd startStarting glusterd: [ OK ][root@server02 yum.repos.d]# chkconfig glusterd on[root@server02 yum.repos.d]# chkconfig --list glusterdglusterd 0:off1:off2:on3:on4:on5:on6:off
8、查看gluster集群节点和卷的信息
[root@server02 yum.repos.d]# gluster peer statusNumber of Peers: 1Hostname: server01Uuid: e90a3b54-5a9d-4e57-b502-86f9aad8b576State: Peer in Cluster (Connected)[root@server02 yum.repos.d]# gluster volume statusStatus of volume: dht-volume01Gluster 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 11966NFS 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[root@server02 yum.repos.d]# ll /glusterfs-xfs-mount/total 16drwx------ 2 root root 16384 Apr 18 14:29 lost+found[root@server02 yum.repos.d]# cd /glusterfs-xfs-mount/[root@server02 glusterfs-xfs-mount]# dd if=/dev/zero of=server02.img bs=1M count=512512+0 records in512+0 records out536870912 bytes (537 MB) copied, 5.85478 s, 91.7 MB/s[root@server02 glusterfs-xfs-mount]# lslost+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
[root@server01 glusterfs-xfs-mount]# gluster peer probe server04peer probe: success. [root@server01 glusterfs-xfs-mount]# gluster peer statusNumber of Peers: 3Hostname: server02Uuid: c58d0715-32ff-4962-90d9-4275fa65793aState: Peer in Cluster (Connected)Hostname: server03Uuid: 5110d0af-fdd9-4c82-b716-991cf0601b53State: Peer in Cluster (Connected)Hostname: server04Uuid: d653b5c2-dac4-428c-bf6f-eea393adbb16State: Peer in Cluster (Connected)
2、添加一个节点卷的信息到dht-volume的brick中
[root@server01 glusterfs-xfs-mount]# gluster volume add-brickUsage: volume add-brick[ ] ... [force][root@server01 glusterfs-xfs-mount]# gluster volume add-brick dht-volume01 server04:/glusterfs-xfs-mountvolume add-brick: failed: Pre Validation failed on server04. The brick server04:/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 command if you want to override this behavior.[root@server01 glusterfs-xfs-mount]# gluster volume add-brick dht-volume01 server04:/glusterfs-xfs-mount forcevolume add-brick: success[root@server01 glusterfs-xfs-mount]# gluster volume statusStatus of volume: dht-volume01Gluster 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 11966Brick 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 12284NFS 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
[root@server01 ~]# gluster volume remove-brick dht-volume01 server04:/glusterfs-xfs-mount/ Usage: volume remove-brick[replica ] ... [root@server01 ~]# gluster volume remove-brick dht-volume01 server04:/glusterfs-xfs-mount/ commitRemoving brick(s) can result in data loss. Do you want to Continue? (y/n) yvolume remove-brick commit: successCheck 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 removed brick. [root@server01 ~]# gluster volume statusStatus of volume: dht-volume01Gluster 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 11966NFS 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)
[root@server01 ~]# gluster volume rebalance dht-volume01Usage: volume rebalance{ {fix-layout start} | {start [force]|stop|status}}[root@server01 ~]# gluster volume rebalance dht-volume01 fix-layout startvolume rebalance: dht-volume01: success: Rebalance on dht-volume01 has been started successfully. Use rebalance status command to check status of the rebalance process.ID: 6ce8fd86-dd1e-4ce3-bb44-82532b5055dd[root@server01 ~]# gluster volume rebalance dht-volume01 fix-layout statusUsage: volume rebalance { {fix-layout start} | {start [force]|stop|status}}[root@server01 ~]# glustergluster> volume rebalance dht-volume01 status Node Rebalanced-files size scanned failures skipped status run time in h:m:s --------- ----------- ----------- ----------- ----------- ----------- ------------ -------------- localhost 0 0Bytes 0 0 0 fix-layout completed 0:0:0 server02 0 0Bytes 0 0 0 fix-layout completed 0:0:0 server03 0 0Bytes 0 0 0 fix-layout completed 0:0:0volume rebalance: dht-volume01: success[root@server01 glusterfs-xfs-mount]# cd /glusterfs-xfs-mount/[root@server01 glusterfs-xfs-mount]# gluster volume set dht-volume01 nfs.disable onvolume set: success[root@server01 glusterfs-xfs-mount]# gluster volume statusStatus of volume: dht-volume01Gluster 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 Task Status of Volume dht-volume01------------------------------------------------------------------------------Task : Rebalance ID : 6ce8fd86-dd1e-4ce3-bb44-82532b5055ddStatus : completed [root@server01 glusterfs-xfs-mount]# touch {1..100}.txt[root@server01 glusterfs-xfs-mount]# ls100.txt 12.txt 16.txt 20.txt 25.txt 3.txt 55.txt 65.txt 70.txt 75.txt 92.txt lost+found10.txt 14.txt 18.txt 21.txt 2.txt 43.txt 57.txt 67.txt 71.txt 77.txt client2.iso test.img11.txt 15.txt 1.txt 22.txt 30.txt 47.txt 61.txt 6.txt 72.txt 88.txt client.iso[root@server02 glusterfs-xfs-mount]# ls13.txt 23.txt 28.txt 34.txt 39.txt 46.txt 52.txt 66.txt 76.txt 81.txt 8.txt 93.txt17.txt 26.txt 29.txt 35.txt 41.txt 4.txt 58.txt 68.txt 79.txt 83.txt 90.txt 94.txt19.txt 27.txt 33.txt 37.txt 42.txt 51.txt 62.txt 73.txt 80.txt 86.txt 91.txt 97.txt[root@server03 ~]# cd /glusterfs-xfs-mount/[root@server03 glusterfs-xfs-mount]# ls24.txt 36.txt 44.txt 49.txt 54.txt 5.txt 64.txt 78.txt 84.txt 89.txt 98.txt lost+found31.txt 38.txt 45.txt 50.txt 56.txt 60.txt 69.txt 7.txt 85.txt 95.txt 99.txt server03.img32.txt 40.txt 48.txt 53.txt 59.txt 63.txt 74.txt 82.txt 87.txt 96.txt 9.txt server04.iso[root@client01 ~]# cd /glusterFS-mount/[root@client01 glusterFS-mount]# ls100.txt 18.txt 26.txt 34.txt 42.txt 50.txt 59.txt 67.txt 75.txt 83.txt 91.txt 9.txt10.txt 19.txt 27.txt 35.txt 43.txt 51.txt 5.txt 68.txt 76.txt 84.txt 92.txt client2.iso11.txt 1.txt 28.txt 36.txt 44.txt 52.txt 60.txt 69.txt 77.txt 85.txt 93.txt client.iso12.txt 20.txt 29.txt 37.txt 45.txt 53.txt 61.txt 6.txt 78.txt 86.txt 94.txt lost+found13.txt 21.txt 2.txt 38.txt 46.txt 54.txt 62.txt 70.txt 79.txt 87.txt 95.txt server03.img14.txt 22.txt 30.txt 39.txt 47.txt 55.txt 63.txt 71.txt 7.txt 88.txt 96.txt server04.iso15.txt 23.txt 31.txt 3.txt 48.txt 56.txt 64.txt 72.txt 80.txt 89.txt 97.txt test.img16.txt 24.txt 32.txt 40.txt 49.txt 57.txt 65.txt 73.txt 81.txt 8.txt 98.txt17.txt 25.txt 33.txt 41.txt 4.txt 58.txt 66.txt 74.txt 82.txt 90.txt 99.txt文件均衡分布的功能实现了
六、配置gluster客户端
[root@client01 ~]# cat /etc/hosts127.0.0.1 localhost localhost.localdomain localhost4 localhost4.localdomain4::1 localhost localhost.localdomain localhost6 localhost6.localdomain6192.168.1.11server01192.168.1.12server02192.168.1.13server03192.168.1.14server04[root@client01 ~]# mkdir -p /glusterFS-mount[root@client01 ~]# mount -t glusterfs server01:/dht-volume01 /glusterFS-mount/[root@client01 ~]# df -hFilesystem Size Used Avail Use% Mounted on/dev/sda3 193G 7.6G 176G 5% /tmpfs 932M 76K 932M 1% /dev/shm/dev/sda1 190M 41M 139M 23% /bootserver01:/dht-volume01 59G 1.7G 55G 3% /glusterFS-mount[root@client01 ~]# cd /glusterFS-mount/[root@client01 glusterFS-mount]# LS-bash: LS: command not found[root@client01 glusterFS-mount]# lslost+found server02.img server03.img test.img[root@client01 glusterFS-mount]# dd if=/dev/zero of=client.iso bs=1M count=123123+0 records in123+0 records out128974848 bytes (129 MB) copied, 1.52512 s, 84.6 MB/s[root@client01 glusterFS-mount]# lsclient.iso lost+found server02.img server03.img test.img[root@client01 glusterFS-mount]# dd if=/dev/zero of=client2.iso bs=1M count=456456+0 records in456+0 records out478150656 bytes (478 MB) copied, 8.76784 s, 54.5 MB/s[root@client01 glusterFS-mount]# lsclient2.iso client.iso lost+found server02.img server03.img test.img[root@client01 glusterFS-mount]# lsclient2.iso client.iso lost+found server02.img server03.img test.img[root@client01 glusterFS-mount]# df -hFilesystem Size Used Avail Use% Mounted on/dev/sda3 193G 7.2G 176G 4% /tmpfs 932M 76K 932M 1% /dev/shm/dev/sda1 190M 41M 139M 23% /bootserver01:/dht-volume01 40G 1.7G 36G 5% /glusterFS-mount[root@client01 glusterFS-mount]# df -hFilesystem Size Used Avail Use% Mounted on/dev/sda3 193G 7.6G 176G 5% /tmpfs 932M 80K 932M 1% /dev/shm/dev/sda1 190M 41M 139M 23% /bootserver01:/dht-volume01 59G 2.2G 54G 4% /glusterFS-mount[root@client01 glusterFS-mount]# cd ~[root@client01 ~]# mount -aMount failed. Please check the log file for more details.Mount failed. Please check the log file for more details.[root@client01 ~]# lsanaconda-ks.cfg Documents install.log Music Public VideosDesktop Downloads install.log.syslog Pictures Templates[root@client01 ~]# df -hFilesystem Size Used Avail Use% Mounted on/dev/sda3 193G 7.6G 176G 5% /tmpfs 932M 80K 932M 1% /dev/shm/dev/sda1 190M 41M 139M 23% /bootserver01:/dht-volume01 79G 2.3G 72G 4% /glusterFS-mount通过容量差别可以发现,节点的卷已经添加成功
七、在挂载glusterFS的客户机的目录下,使用samba分享给windows机器使用
1、samba服务的安装
[root@client01 ~]# yum -y install samba[root@client01 ~]# /etc/init.d/smb restartShutting down SMB services: [ OK ]Starting SMB services: [ OK ][root@client01 ~]# /etc/init.d/nmb restartShutting down NMB services: [ OK ]Starting NMB services: [ OK ][root@client01 ~]# chkconfig smb on[root@client01 ~]# chkconfig nmb on[root@client01 ~]# vim /etc/samba/smb.conf 配置文件如下: workgroup = WORKGROUP (工作组) server string = Samba Server Version %v (显示版本) hosts allow = 127. 192.168.1. 10.10.10. (允许登陆的主机) log file = /var/log/samba/log.%m (日志存放的地方) max log size = 50 (最大的日志数量) security = user (samba验证的级别) passdb backend = tdbsam[云盘测试平台] comment = yunpan browseable = yes writable = yes public = yes path = /glusterFS-mount valid users = wanlong[root@client01 ~]# /etc/init.d/smb restartShutting down SMB services: [ OK ]Starting SMB services: [ OK ][root@client01 ~]# /etc/init.d/nmb restartShutting down NMB services: [ OK ]Starting NMB services: [ OK ]
2、samba用户的配置
[root@client01 ~]# adduser jifang01 -s /sbin/nologin [root@client01 ~]# id jifang01uid=501(jifang01) gid=501(jifang01) groups=501(jifang01)[root@client01 ~]# smbpasswd -a jifang01New SMB password:Retype new SMB password:Added user jifang01.
3、设置本地文件夹权限
[root@client01 ~]# df -hFilesystem Size Used Avail Use% Mounted on/dev/sda3 193G 7.6G 176G 5% /tmpfs 932M 72K 932M 1% /dev/shm/dev/sda1 190M 41M 139M 23% /bootserver01:/dht-volume01 79G 1.8G 73G 3% /glusterFS-mount[root@client01 ~]# chmod 777 /glusterFS-mount/ -R
4、在windows服务端映射网络驱动器后,进行验证
