配置规划
下载并安装
1、下载地址：http://bits.gluster.org/pub/gluster/glusterfs/3.4.2/x86_64/
需要下载的rpm包
2、RPM安装包

glusterfs-api-3.4.2-1.el6.x86_64.rpm
glusterfs-cli-3.4.2-1.el6.x86_64.rpm
glusterfs-fuse-3.4.2-1.el6.x86_64.rpm
glusterfs-libs-3.4.2-1.el6.x86_64.rpm
glusterfs-server-3.4.2-1.el6.x86_64.rpm
开始下载：
wget http://bits.gluster.org/pub/gluster/glusterfs/3.4.2/x86_64/glusterfs-3.4.2-1.el6.x86_64.rpm wget http://bits.gluster.org/pub/gluster/glusterfs/3.4.2/x86_64/glusterfs-api-3.4.2-1.el6.x86_64.rpm wget http://bits.gluster.org/pub/gluster/glusterfs/3.4.2/x86_64/glusterfs-cli-3.4.2-1.el6.x86_64.rpm wget http://bits.gluster.org/pub/gluster/glusterfs/3.4.2/x86_64/glusterfs-fuse-3.4.2-1.el6.x86_64.rpm wget http://bits.gluster.org/pub/gluster/glusterfs/3.4.2/x86_64/glusterfs-libs-3.4.2-1.el6.x86_64.rpm wget http://bits.gluster.org/pub/gluster/glusterfs/3.4.2/x86_64/glusterfs-server-3.4.2-1.el6.x86_64.rpm
3、依赖包安装
Rpcbind
Libaio
Lvm2-devel
经验：一般来讲，先rpm安装gluster，有报错再按依赖包
[root@Qinglin-A data]# yum install rpcbind libaio lvm2-devel -y
4、软件安装

5、格式化磁盘并挂载，设置开机自启动
1）创建分区，所有服务器同样操作，本次创建了/dev/sdb1和/dev/sdc1
注：下列为例子，每台gluster服务端都创建了/dev/sdb1和/dev/sdc1
[root@Qinglin-A /]# fdisk /dev/sdb
Command (m for help): n
Command action
e extended
p primary partition (1-4)
p
Partition number (1-4): 1
First cylinder (1-1305, default 1):
Using default value 1
Last cylinder, +cylinders or +size{K,M,G} (1-1305, default 1305):
Using default value 1305
Command (m for help): wq
2）格式化磁盘，ext4，所有服务器同样操作，本次格式化了/dev/sdb1和/dev/sdc1
注：下列为例子，每台gluster服务端都格式化了/dev/sdb1和/dev/sdc1
[root@Qinglin-A /]# mkfs.ext4 /dev/sdb1 mke2fs 1.41.12 (17-May-2010) Filesystem label= OS type: Linux Block size=4096 (log=2) Fragment size=4096 (log=2) Stride=0 blocks, Stripe width=0 blocks 655360 inodes, 2620595 blocks 131029 blocks (5.00%) reserved for the super user First data block=0 Maximum filesystem blocks=2684354560 80 block groups 32768 blocks per group, 32768 fragments per group 8192 inodes per group Superblock backups stored on blocks: 32768, 98304, 163840, 229376, 294912, 819200, 884736, 1605632 Writing inode tables: done Creating journal (32768 blocks): done Writing superblocks and filesystem accounting information: done This filesystem will be automatically checked every 30 mounts or 180 days, whichever comes first. Use tune2fs -c or -i to override.
3）开机自动挂载并放到fstab里
挂载：
注：多少个存储节点，就执行多少次下面的命令
[root@Qinglin-A /]# mount /dev/sdb1 /brick1/ [root@Qinglin-A /]# mount /dev/sdc1 /brick2/ [root@Qinglin-A /]# df -h Filesystem Size Used Avail Use% Mounted on /dev/sda2 17G 1.7G 15G 11% / tmpfs 935M 0 935M 0% /dev/shm /dev/sda1 194M 34M 151M 19% /boot /dev/sdb1 9.9G 151M 9.2G 2% /brick1 /dev/sdc1 9.9G 151M 9.2G 2% /brick2
开机自动挂载：
注：多少个存储节点，就执行多少次下面的命令
[root@Qinglin-A /]# vim /etc/fstab # # /etc/fstab # Created by anaconda on Tue Dec 22 11:46:04 2015 # # Accessible filesystems, by reference, are maintained under '/dev/disk' # See man pages fstab(5), findfs(8), mount(8) and/or blkid(8) for more info # UUID=5b700fc3-d716-4f56-be1b-22b16ee2921c / ext4 defaults 1 1 UUID=38903668-682e-4a31-a131-fe65e3213d10 /boot ext4 defaults 1 2 UUID=5591bf6f-0509-4153-9cfc-10cd7eb3b4ee swap swap defaults 0 0 tmpfs /dev/shm tmpfs defaults 0 0 devpts /dev/pts devpts gid=5,mode=620 0 0 sysfs /sys sysfs defaults 0 0 proc /proc proc defaults 0 0 /dev/sdb1 /brick1/ ext4 defaults 0 0 /dev/sdc1 /brick2/ ext4 defaults 0 0
4）开机自启动gluster服务
注：多少个存储节点，就执行多少次下面的命令
[root@Qinglin-A /]# chkconfig glusterd on [root@Qinglin-A /]# chkconfig |grep glusterd glusterd 0:off 1:off 2:on 3:on 4:on 5:on 6:off
5）设置集群节点名hosts，代替使用IP
修改hosts
注：多少个存储节点，就执行多少次下面的命令
[root@Qinglin-A ~]# vim /etc/hosts 127.0.0.1 localhost localhost.localdomain localhost4 localhost4.localdomain4 ::1 localhost localhost.localdomain localhost6 localhost6.localdomain6 192.168.1.210 server1 192.168.1.220 server2 192.168.1.230 server3
ping测试
注：多少个存储节点，就执行多少次下面的命令
[root@Qinglin-A ~]# ping server2 PING server2 (192.168.1.220) 56(84) bytes of data. 64 bytes from server2 (192.168.1.220): icmp_seq=1 ttl=64 time=1.22 ms 64 bytes from server2 (192.168.1.220): icmp_seq=2 ttl=64 time=1.57 ms
Gluster实战部署
1、选择Qinglin-A 192.168.1.210作为当前集群节点
gluster peer probe组建集群
gluster peer probe server2
gluster peer probe server3
[root@Qinglin-A ~]# gluster peer probe server2 peer probe: success [root@Qinglin-A ~]# gluster peer probe server3 peer probe: success
校验刚刚添加的两个节点
[root@Qinglin-A ~]# gluster peer status Number of Peers: 2 Hostname: server2 Port: 24007 Uuid: b35ae918-1c7d-4ab2-9c1f-0c909309142e State: Peer in Cluster (Connected) Hostname: server3 Port: 24007 Uuid: b9d523ff-2637-40bd-b544-ae7852ad8834 State: Peer in Cluster (Connected)
2、创建卷
确定创建卷的类型
确定创建卷的brick列表
确定创建卷的网络类型(TCP/RDMA)
Glustervolume create创建卷，其中下列的testvol是自己命名的
[root@Qinglin-A ~]# gluster volume create testvol server1:/brick1/b1 volume create: testvol: success: please start the volume to access data [root@Qinglin-A ~]# gluster volume start testvol volume start: testvol: success [root@Qinglin-A ~]# gluster volume info Volume Name: testvol Type: Distribute Volume ID: ea92d7e0-637e-4562-b528-56b508db0f1d Status: Started Number of Bricks: 1 Transport-type: tcp Bricks: Brick1: server1:/brick1/b1
3、客户端挂载
修改host，或用IP访问
[root@Qinglin-D ~]# vim /etc/hosts 127.0.0.1 localhost localhost.localdomain localhost4 localhost4.localdomain4 ::1 localhost localhost.localdomain localhost6 localhost6.localdomain6 192.168.1.210 server1 192.168.1.220 server2 192.168.1.230 server3
然后进行挂载
[root@Qinglin-D ~]# mount -t glusterfs server1:/testvol /mnt/ [root@Qinglin-D ~]# df -h Filesystem Size Used Avail Use% Mounted on /dev/sda2 19G 1.7G 16G 10% / tmpfs 495M 0 495M 0% /dev/shm /dev/sda1 194M 29M 155M 16% /boot 192.168.1.210:/data 17G 1.7G 15G 11% /data server1:/testvol 9.9G 151M 9.2G 2% /mnt
4、测试
在客户端上写一个文件，在服务器端上找文件
客户端
[root@Qinglin-D mnt]# touch file [root@Qinglin-D mnt]# mkdir dir [root@Qinglin-D mnt]# ls dir file [root@Qinglin-D mnt]# pwd /mnt
服务端QINGLIN-A
[root@Qinglin-A b1]# cd /brick1/b1/ [root@Qinglin-A b1]# ls dir file
