CentOS 6.4如何安裝及設置GlusterFS

GlusterFS因有很好的擴展性,使用的用戶很多,使用GlusterFS能夠解決網絡存儲、冗余備份等問題,那麼在Linux下要如何安裝GlusterFS呢?今天小編以CentOS6.4為例,給大家介紹下CentOS6.4安裝配置GlusterFS的方法。

環境介紹:

OS: CentOS 6.4 x86_64 Minimal

Servers: sc2-log1,sc2-log2,sc2-log3,sc2-log4

Client: sc2-ads15

具體步驟:

1. 在sc2-log{1-4}上安裝GlusterFS軟件包:

代碼如下

# wget -P /etc/yum.repos.d http://download.gluster.org/pub/gluster/glusterfs/LATEST/CentOS/glusterfs-epel.repo

# yum install -y glusterfs-3.4.2-1.el6 glusterfs-server-3.4.2-1.el6 glusterfs-fuse-3.4.2-1.el6

# /etc/init.d/glusterd start

# chkconfig glusterfsd on

2. 在sc2-log1上配置整個GlusterFS集群:

代碼如下

[root@sc2-log1 ~]# gluster peer probe sc2-log1

1 peer probe: success: on localhost not needed

[root@sc2-log1 ~]# gluster peer probe sc2-log2

1 peer probe: success

[root@sc2-log1 ~]# gluster peer probe sc2-log3

1 peer probe: success

[root@sc2-log1 ~]# gluster peer probe sc2-log4

1 peer probe: success

[root@sc2-log1 ~]# gluster peer status

01 Number of Peers: 3

02

03 Hostname: sc2-log2

04 Port: 24007

05 Uuid: 399973af-bae9-4326-9cbd-b5b05e5d2927

06 State: Peer in Cluster (Connected)

07

08 Hostname: sc2-log3

09 Port: 24007

10 Uuid: 833a7b8d-e3b3-4099-baf9-416ee7213337

11 State: Peer in Cluster (Connected)

12

13 Hostname: sc2-log4

14 Port: 24007

15 Uuid: 54bf115a-0119-4021-af80-7a6bca137fd9

16 State: Peer in Cluster (Connected)

3. 在sc2-log{1-4}上創建數據存放目錄:

代碼如下

# mkdir -p /usr/local/share/{models,geoip,wurfl}

# ls -l /usr/local/share/

1 total 24

2 drwxr-xr-x 2 root root 4096 Apr 1 12:19 geoip

3 drwxr-xr-x 2 root root 4096 Apr 1 12:19 models

4 drwxr-xr-x 2 root root 4096 Apr 1 12:19 wurfl

4. 在sc2-log1上創建GlusterFS磁盤:

代碼如下

[root@sc2-log1 ~]# gluster volume create models replica 4 sc2-log1:/usr/local/share/models sc2-log2:/usr/local/share/models sc2-log3:/usr/local/share/models sc2-log4:/usr/local/share/models force

1 volume create: models: success: please start the volume to access data

[root@sc2-log1 ~]# gluster volume create geoip replica 4 sc2-log1:/usr/local/share/geoip sc2-log2:/usr/local/share/geoip sc2-log3:/usr/local/share/geoip sc2-log4:/usr/local/share/geoip force

1 volume create: geoip: success: please start the volume to access data

[root@sc2-log1 ~]# gluster volume create wurfl replica 4 sc2-log1:/usr/local/share/wurfl sc2-log2:/usr/local/share/wurfl sc2-log3:/usr/local/share/wurfl sc2-log4:/usr/local/share/wurfl force

1 volume create: wurfl: success: please start the volume to access data

[root@sc2-log1 ~]# gluster volume start models

1 volume start: models: success

[root@sc2-log1 ~]# gluster volume start geoip

1 volume start: geoip: success

[root@sc2-log1 ~]# gluster volume start wurfl

1 volume start: wurfl: success

[root@sc2-log1 ~]# gluster volume info

01 Volume Name: models

02 Type: Replicate

03 Volume ID: b29b22bd-6d8c-45c0-b199-91fa5a76801f

04 Status: Started

05 Number of Bricks: 1 x 4 = 4

06 Transport-type: tcp

07 Bricks:

08 Brick1: sc2-log1:/usr/local/share/models

09 Brick2: sc2-log2:/usr/local/share/models

10 Brick3: sc2-log3:/usr/local/share/models

11 Brick4: sc2-log4:/usr/local/share/models

12

13 Volume Name: geoip

14 Type: Replicate

15 Volume ID: 69b0caa8-7c23-4712-beae-6f536b1cffa3

16 Status: Started

17 Number of Bricks: 1 x 4 = 4

18 Transport-type: tcp

19 Bricks:

20 Brick1: sc2-log1:/usr/local/share/geoip

21 Brick2: sc2-log2:/usr/local/share/geoip

22 Brick3: sc2-log3:/usr/local/share/geoip

23 Brick4: sc2-log4:/usr/local/share/geoip

24

25 Volume Name: wurfl

26 Type: Replicate

27 Volume ID: c723a99d-eeab-4865-819a-c0926cf7b88a

28 Status: Started

29 Number of Bricks: 1 x 4 = 4

30 Transport-type: tcp

31 Bricks:

32 Brick1: sc2-log1:/usr/local/share/wurfl

33 Brick2: sc2-log2:/usr/local/share/wurfl

34 Brick3: sc2-log3:/usr/local/share/wurfl

35 Brick4: sc2-log4:/usr/local/share/wurfl

5. 在sc2-ads15上部署客戶端並mount GlusterFS文件系統:

[sc2-ads15][root@sc2-ads15 ~]# wget -P /etc/yum.repos.d http://download.gluster.org/pub/gluster/glusterfs/LATEST/CentOS/glusterfs-epel.repo

[sc2-ads15][root@sc2-ads15 ~]# yum install -y glusterfs-3.4.2-1.el6 glusterfs-fuse-3.4.2-1.el6

[sc2-ads15][root@sc2-ads15 ~]# mkdir -p /mnt/{models,geoip,wurfl}

[sc2-ads15][root@sc2-ads15 ~]# mount -t glusterfs -o ro sc2-log3:models /mnt/models/

[sc2-ads15][root@sc2-ads15 ~]# mount -t glusterfs -o ro sc2-log3:geoip /mnt/geoip/

[sc2-ads15][root@sc2-ads15 ~]# mount -t glusterfs -o ro sc2-log3:wurfl /mnt/wurfl/

[sc2-ads15][root@sc2-ads15 ~]# df -h

1 Filesystem Size Used Avail Use% Mounted on

2 /dev/mapper/vg_t-lv_root

3 59G 7.7G 48G 14% /

4 tmpfs 3.9G 0 3.9G 0% /dev/shm

5 /dev/xvda1 485M 33M 428M 8% /boot

6 sc2-log3:models 98G 8.6G 85G 10% /mnt/models

7 sc2-log3:geoip 98G 8.6G 85G 10% /mnt/geoip

8 sc2-log3:wurfl 98G 8.6G 85G 10% /mnt/wurfl

6. 相關數據讀寫可用性測試:

在sc2-ads15掛載點上寫入數據:

代碼如下

[sc2-ads15][root@sc2-ads15 ~]# umount /mnt/models

[sc2-ads15][root@sc2-ads15 ~]# mount -t glusterfs sc2-log3:models /mnt/models/

[sc2-ads15][root@sc2-ads15 ~]# echo “This is sc2-ads15” 》 /mnt/models/hello.txt

[sc2-ads15][root@sc2-ads15 ~]# mkdir /mnt/testdir

在sc2-log1數據目錄中進行查看:

[root@sc2-log1 ~]# ls /usr/local/share/models/

1 hello.txt testdir

結果: 數據寫入成功

在sc2-log1數據目錄中直接寫入數據:

代碼如下

[root@sc2-log1 ~]# echo “This is sc2-log1” 》 /usr/local/share/models/hello.2.txt

[root@sc2-log1 ~]# mkdir /usr/local/share/models/test2

在sc2-ads15掛載點上進行查看:

[sc2-ads15][root@sc2-ads15 ~]# ls /mnt/models

[sc2-ads15][root@sc2-ads15 ~]# ls -l /mnt/models

1 hello.txt testdir

結果: 數據寫入失敗

在sc2-log1掛載點上寫入數據:

代碼如下

[root@sc2-log1 ~]# mount -t glusterfs sc2-log1:models /mnt/models/

[root@sc2-log1 ~]# echo “This is sc2-log1” 》 /mnt/models/hello.3.txt

[root@sc2-log1 ~]# mkdir /mnt/models/test3

在sc2-ads15掛載點上進行查看:

[sc2-ads15][root@sc2-ads15 models]# ls /mnt/models

1 hello.2.txt hello.3.txt hello.txt test2 test3 testdir

結果: 數據寫入成功,同時之前寫入失敗的數據也成功加載了。

最終結論:

在數據目錄中直接寫入數據,會導致其它節點因為得不到通知而使數據同步失敗。

正確的做法是所有的讀寫操作都通過掛載點來進行。

7. 其它操作筆記:

刪除GlusterFS磁盤:

代碼如下

# gluster volume stop models

# gluster volume delete models

卸載GlusterFS磁盤:

代碼如下

sc2-log4

ACL訪問控制:

代碼如下

# gluster volume set models auth.allow 10.60.1.*,10.70.1.*

添加GlusterFS節點:

代碼如下

# gluster peer probe sc2-log5

# gluster peer probe sc2-log6

# gluster volume add-brick models sc2-log5:/data/gluster sc2-log6:/data/gluster

遷移GlusterFS磁盤數據:

代碼如下

# gluster volume remove-brick models sc2-log1:/usr/local/share/models sc2-log5:/usr/local/share/models start

# gluster volume remove-brick models sc2-log1:/usr/local/share/models sc2-log5:/usr/local/share/models status

# gluster volume remove-brick models sc2-log1:/usr/local/share/models sc2-log5:/usr/local/share/models commit

修復GlusterFS磁盤數據(例如在sc2-log1宕機的情況下):

代碼如下

# gluster volume replace-brick models sc2-log1:/usr/local/share/models sc2-log5:/usr/local/share/models commit -force

# gluster volume heal models full

通過本文的介紹,想必你已經對GlusterFS在CentOS6.4的安裝配置有了一定的了解,除此之外,本文還介紹了GlusterFS的其他操作方法。
