一、GlusterFS的安装

  • 以下为示例环境

1.1 部署环境

系统 CentOS 7.3
glusterfs版本 3.12.1
主机名 IP
server1 10.81.29.87
server2 10.81.9.115

存储节点hosts解析

所有节点都需要配置存储节点hostname解析

  1. [root@server1 ~]# cat /etc/hosts
  2. 127.0.0.1 localhost
  3. ::1         localhost localhost.localdomain localhost6 localhost6.localdomain6
  4. 10.81.29.87 server1
  5. 10.81.9.115 server2

格式化磁盘、创建目录并挂载

  1. mkfs.xfs  /dev/vdb
  2. mkdir  -p /data
  3. echo "/dev/vdb  /data  xfs  defaults 1 2" >>/etc/fstab
  4. mount -a

查看

  1. [root@server1 ~]# df -h
  2. Filesystem      Size  Used Avail Use% Mounted on
  3. /dev/vda1        40G  1.9G   36G   5% /
  4. devtmpfs        1.9G     0  1.9G   0% /dev
  5. tmpfs           1.9G     0  1.9G   0% /dev/shm
  6. tmpfs           1.9G  332K  1.9G   1% /run
  7. tmpfs           1.9G     0  1.9G   0% /sys/fs/cgroup
  8. tmpfs           380M     0  380M   0% /run/user/0
  9. /dev/vdb         20G   33M   20G   1% /data
  1. [root@server2 ~]# df -h
  2. Filesystem      Size  Used Avail Use% Mounted on
  3. /dev/vda1        40G  1.9G   36G   5% /
  4. devtmpfs        1.9G     0  1.9G   0% /dev
  5. tmpfs           1.9G     0  1.9G   0% /dev/shm
  6. tmpfs           1.9G  344K  1.9G   1% /run
  7. tmpfs           1.9G     0  1.9G   0% /sys/fs/cgroup
  8. tmpfs           380M     0  380M   0% /run/user/0
  9. /dev/vdb         20G   33M   20G   1% /data

1.2 安装

  1. yum install centos-release-gluster -y
  2. yum install glusterfs-server -y

1.3 启动GlusterFS服务

  1. systemctl  start   glusterd.service
  2. systemctl  enable  glusterd.service
  3. systemctl  status  glusterd.service

1.4 配置信任池(一端添加就行)

  1. [root@server1 ~]# gluster peer probe server2
  2. peer probe: success.
  3. [root@server1 ~]# gluster peer status
  4. Number of Peers: 1
  6. Hostname: server2
  7. Uuid: be69468e-94b6-45a6-8a3d-bea86c2702dc
  8. State: Peer in Cluster (Connected)

1.5 创建卷

  1. # 所有节点都需执行  
  2. mkdir  -p /data/glusterfs
  4. # 创建一个卷
  5. gluster volume create data replica 2 server1:/data/glusterfs server2:/data/glusterfs
  7. Replica 2 volumes are prone to split-brain. Use Arbiter or Replica 3 to avoid this. See: http://docs.gluster.org/en/latest/Administrator%20Guide/Split%20brain%20and%20ways%20to%20deal%20with%20it/.
  8. Do you still want to continue?
  9.  (y/n) y
  10. volume create: data: success: please start the volume to access data

1.6 查看卷的信息

  1. [root@server1 ~]# gluster volume info
  3. Volume Name: data
  4. Type: Replicate
  5. Volume ID: 8c16603c-2fab-4117-8020-2310b0041b35
  6. Status: Created
  7. Snapshot Count: 0
  8. Number of Bricks: 1 x 2 = 2
  9. Transport-type: tcp
  10. Bricks:
  11. Brick1: server1:/data/glusterfs
  12. Brick2: server2:/data/glusterfs
  13. Options Reconfigured:
  14. transport.address-family: inet
  15. nfs.disable: on

启动卷

  1. [root@server1 ~]# gluster volume start data
  2. volume start: data: success

1.7 挂载测试

  1. #server1 挂载
  2. [root@server1 ~]# mount -t glusterfs server1:/data /mnt
  4. #server2 挂载
  5. [root@server2 ~]# mount -t glusterfs server2:/data /mnt
  7. #在server2上创建文件
  8. [root@server2 ~]# touch /mnt/{1..10}test.txt
  10. #在server1上查看
  11. [root@server1 ~]# ls /mnt/
  12. 10test.txt  2test.txt  4test.txt  6test.txt  8test.txt
  13. 1test.txt   3test.txt  5test.txt  7test.txt  9test.txt
