一、GlusterFS的安装
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 |
hosts解析
[root@server1 ~]# cat /etc/hosts
127.0.0.1 localhost
::1 localhost localhost.localdomain localhost6 localhost6.localdomain6
10.81.29.87 server1
10.81.9.115 server2
格式化磁盘、创建目录并挂载
#在所有存储节点执行
#格式化磁盘
mkfs.xfs /dev/vdb
#制作挂载点目录
mkdir -p /data
#编辑 /etc/fstab 配置开机挂载信息
echo "/dev/vdb /data xfs defaults 1 2" >>/etc/fstab
#执行挂载操作
mount -a
查看挂载情况
[root@server1 ~]# df -h
Filesystem Size Used Avail Use% Mounted on
/dev/vda1 40G 1.9G 36G 5% /
devtmpfs 1.9G 0 1.9G 0% /dev
tmpfs 1.9G 0 1.9G 0% /dev/shm
tmpfs 1.9G 332K 1.9G 1% /run
tmpfs 1.9G 0 1.9G 0% /sys/fs/cgroup
tmpfs 380M 0 380M 0% /run/user/0
/dev/vdb 20G 33M 20G 1% /data #出现这条记录,即挂载成功
[root@server2 ~]# df -h
Filesystem Size Used Avail Use% Mounted on
/dev/vda1 40G 1.9G 36G 5% /
devtmpfs 1.9G 0 1.9G 0% /dev
tmpfs 1.9G 0 1.9G 0% /dev/shm
tmpfs 1.9G 344K 1.9G 1% /run
tmpfs 1.9G 0 1.9G 0% /sys/fs/cgroup
tmpfs 380M 0 380M 0% /run/user/0
/dev/vdb 20G 33M 20G 1% /data #出现这条记录,即挂载成功
1.2 安装glusterfs
#所有存储节点执行
yum install centos-release-gluster -y
yum install glusterfs-server -y
1.3 启动GlusterFS服务
#所有存储节点执行
systemctl start glusterd.service
systemctl enable glusterd.service
systemctl status glusterd.service
1.4 配置信任池(一端添加就行)
[root@server1 ~]# gluster peer probe server2
peer probe: success.
[root@server1 ~]# gluster peer status
Number of Peers: 1
Hostname: server2
Uuid: be69468e-94b6-45a6-8a3d-bea86c2702dc
State: Peer in Cluster (Connected)
1.5 创建卷
# 所有节点都需执行
mkdir -p /data/glusterfs
# 创建一个卷
gluster volume create data replica 2 server1:/data/glusterfs server2:/data/glusterfs
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/.
Do you still want to continue?
(y/n) y
volume create: data: success: please start the volume to access data
1.6 查看卷的信息
[root@server1 ~]# gluster volume info
Volume Name: data
Type: Replicate
Volume ID: 8c16603c-2fab-4117-8020-2310b0041b35
Status: Created
Snapshot Count: 0
Number of Bricks: 1 x 2 = 2
Transport-type: tcp
Bricks:
Brick1: server1:/data/glusterfs
Brick2: server2:/data/glusterfs
Options Reconfigured:
transport.address-family: inet
nfs.disable: on
启动卷
[root@server1 ~]# gluster volume start data
volume start: data: success
1.7 挂载测试
#server1 挂载
[root@server1 ~]# mount -t glusterfs server1:/data /mnt
#server2 挂载
[root@server2 ~]# mount -t glusterfs server2:/data /mnt
#在server2上创建文件
[root@server2 ~]# touch /mnt/{1..10}test.txt
#在server1上查看文件是否同步,如出现上一步创建的文件,说明同步成功
[root@server1 ~]# ls /mnt/
10test.txt 2test.txt 4test.txt 6test.txt 8test.txt
1test.txt 3test.txt 5test.txt 7test.txt 9test.txt
