  GlusterFS因有很好的扩展性,使用的用户很多,使用GlusterFS能够解决网络存储、冗余备份等问题,那么在Linux下要如何安装GlusterFS呢?今天小编以CentOS6.4为例,给大家介绍下CentOS6.4安装配置GlusterFS的方法。

CentOS 6.4如何安装及设置GlusterFS

  环境介绍:

  OS: CentOS 6.4 x86_64 Minimal

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

  Client: sc2-ads15

  具体步骤:

  1. 在sc2-log{1-4}上安装GlusterFS软件包:

  代码如下

  # 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上配置整个GlusterFS集群:

  代码如下

  [[email protected] ~]# gluster peer probe sc2-log1

  1 peer probe: success: on localhost not needed

  [[email protected] ~]# gluster peer probe sc2-log2

  1 peer probe: success

  [[email protected] ~]# gluster peer probe sc2-log3

  1 peer probe: success

  [[email protected] ~]# gluster peer probe sc2-log4

  1 peer probe: success

  [[email protected] ~]# 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}上创建数据存放目录:

  代码如下

  # 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上创建GlusterFS磁盘:

  代码如下

  [[email protected] ~]# 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

  [[email protected] ~]# 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

  [[email protected] ~]# 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

  [[email protected] ~]# gluster volume start models

  1 volume start: models: success

  [[email protected] ~]# gluster volume start geoip

  1 volume start: geoip: success

  [[email protected] ~]# gluster volume start wurfl

  1 volume start: wurfl: success

  [[email protected] ~]# 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上部署客户端并mount GlusterFS文件系统:

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

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

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

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

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

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

  [sc2-ads15][[email protected] ~]# 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. 相关数据读写可用性测试:

  在sc2-ads15挂载点上写入数据:

  代码如下

  [sc2-ads15][[email protected] ~]# umount /mnt/models

  [sc2-ads15][[email protected] ~]# mount -t glusterfs sc2-log3:models /mnt/models/

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

  [sc2-ads15][[email protected] ~]# mkdir /mnt/testdir

  在sc2-log1数据目录中进行查看:

  [[email protected] ~]# ls /usr/local/share/models/

  1 hello.txt testdir

  结果: 数据写入成功

  在sc2-log1数据目录中直接写入数据:

  代码如下

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

  [[email protected] ~]# mkdir /usr/local/share/models/test2

  在sc2-ads15挂载点上进行查看:

  [sc2-ads15][[email protected] ~]# ls /mnt/models

  [sc2-ads15][[email protected] ~]# ls -l /mnt/models

  1 hello.txt testdir

  结果: 数据写入失败

  在sc2-log1挂载点上写入数据:

  代码如下

  [[email protected] ~]# mount -t glusterfs sc2-log1:models /mnt/models/

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

  [[email protected] ~]# mkdir /mnt/models/test3

  在sc2-ads15挂载点上进行查看:

  [sc2-ads15][[email protected] models]# ls /mnt/models

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

  结果: 数据写入成功,同时之前写入失败的数据也成功加载了。

  最终结论:

  在数据目录中直接写入数据,会导致其它节点因为得不到通知而使数据同步失败。

  正确的做法是所有的读写操作都通过挂载点来进行。

  7. 其它操作笔记:

  删除GlusterFS磁盘:

  代码如下

  # gluster volume stop models

  # gluster volume delete models

  卸载GlusterFS磁盘:

  代码如下

  sc2-log4

  ACL访问控制:

  代码如下

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

  添加GlusterFS节点:

  代码如下

  # gluster peer probe sc2-log5

  # gluster peer probe sc2-log6

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

  迁移GlusterFS磁盘数据:

  代码如下

  # 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

  修复GlusterFS磁盘数据(例如在sc2-log1宕机的情况下):

  代码如下

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

  # gluster volume heal models full

  通过本文的介绍,想必你已经对GlusterFS在CentOS6.4的安装配置有了一定的了解,除此之外,本文还介绍了GlusterFS的其他操作方法。
