格式化磁盘
采用xfs存储
mkfs.xfs -f -i size=512 /dev/vdb mkdir -p /data/gcluster echo '/dev/vdb /data/gcluster xfs defaults 1 2' >> /etc/fstab mount -a && mount [root@master-12 ~]# mkfs.xfs -f -i size=512 /dev/vdb meta-data=/dev/vdb isize=512 agcount=4, agsize=3276800 blks = sectsz=512 attr=2, projid32bit=1 = crc=1 finobt=0, sparse=0 data = bsize=4096 blocks=13107200, imaxpct=25 = sunit=0 swidth=0 blks naming =version 2 bsize=4096 ascii-ci=0 ftype=1 log =internal log bsize=4096 blocks=6400, version=2 = sectsz=512 sunit=0 blks, lazy-count=1 realtime =none extsz=4096 blocks=0, rtextents=0 [root@slave-09 ~]# lsblk NAME MAJ:MIN RM SIZE RO TYPE MOUNTPOINT sr0 11:0 1 37.7M 0 rom vda 253:0 0 50G 0 disk └―vda1 253:1 0 50G 0 part / vdb 253:16 0 50G 0 disk /data/gcluster 安装glusterFS
yum install -y centos-release-gluster yum install -y glusterfs glusterfs-server glusterfs-fuse glusterfs-rdma [root@slave-09 ~]# systemctl start glusterd.service [root@slave-09 ~]# systemctl status glusterd.service 加入集群
[root@master-12 ~]# gluster peer probe master-12 peer probe: success. Probe on localhost not needed [root@master-12 ~]# [root@master-12 ~]# gluster peer probe slave-09 peer probe: success. [root@master-12 ~]# gluster peer probe slave-08 查看集群状态
[root@master-12 ~]# gluster peer status Number of Peers: 2 Hostname: slave-09 Uuid: 28815fe9-ce7f-4ed3-ae94-ef7d032b6854 State: Peer in Cluster (Connected) Hostname: slave-08 Uuid: ef857dbe-7801-4f26-aa0e-95b8f98e1c64 State: Peer in Cluster (Connected) 安装gluster volume
在每个节点上创建volume目录
mkdir -p /data/gcluster/data
gluster volume create gv0 replica 3 master-12:/data/gcluster/data slave-09:/data/gcluster/data slave-08:/data/gcluster/data [root@master-12 ~]# gluster volume create gv0 replica 3 master-12:/data/gcluster/data slave-09:/data/gcluster/data slave-08:/data/gcluster/data volume create: gv0: success: please start the volume to access data [root@master-12 ~]# gluster volume start gv0 volume start: gv0: success [root@master-12 ~]# gluster volume info Volume Name: gv0 Type: Replicate Volume ID: e5dcd35f-94af-4a6d-a8ad-feb1b5a4278d Status: Started Snapshot Count: 0 Number of Bricks: 1 x 3 = 3 Transport-type: tcp Bricks: Brick1: master-12:/data/gcluster/data Brick2: slave-09:/data/gcluster/data Brick3: slave-08:/data/gcluster/data Options Reconfigured: transport.address-family: inet nfs.disable: on performance.client-io-threads: off 测试
mount -t glusterfs master-12:/gv0 /mnt for i in `seq -w 1 100`; do cp -rp /var/log/messages /mnt/copy-test-$i; done 在每个服务器上都会有100个文件
