Glusterfs初试

Gluster的模式及介绍在此不表，这里只记录安装及配置过程。

1.整体环境

server1 : gfs1.cluster.com

server2 : gfs2.cluster.com

Client:

2.安装Gluster

下载软件

https://access.redhat.com/downloads/content/186/ver=3/rhel---7/3.4/x86_64/product-software

下载 Red Hat Gluster Storage Server 3.4 on RHEL 7 Installation DVD

安装RHEL 7.6的最小软件安装，将iso文件mount成cdrom, 然后修改yum源

mkdir -p /repo/base

mount /dev/cdrom /repo/base

vi /etc/yum.repos.d/base.repo

[rhel7.]

name=rhel7.

baseurl=file:///repo/base/

enabled=

gpgcheck=

安装

yum install -y redhat-storage-server

systemctl start glusterd

systemctl enable glusterd

systemctl status glusterd验证一下

[root@gfs1 mnt]# systemctl status glusterd

● glusterd.service - GlusterFS, a clustered file-system server

   Loaded: loaded (/usr/lib/systemd/system/glusterd.service; enabled; vendor preset: disabled)

配置防火墙

简单起见直接关闭了，以后补充开放具体网段

systemctl stop firewalld

systemctl disable firewalld

修改主机名以及/etc/hosts

每台机器执行，并修改/etc/hosts

hostnamectl set-hostname gfs1.cluster.com

添加存储

在每台glusterfs的server上加入一块存储盘，并进行初始化

fdisk /dev/sdb

mkfs.ext4 /dev/sdb1

在每个节点上运行以下命令挂载

mkdir -p /data/gluster

mount /dev/sdb1 /data/gluster

echo "/dev/sdb1 /data/gluster ext4 defaults 0 0" | tee --append /etc/fstab

3.配置Glusterfs

在节点1上运行

gluster peer probe gfs2.cluster.com

验证

[root@gfs1 mnt]# gluster peer status

Number of Peers:

Hostname: gfs2.cluster.com

Uuid: 818cc628-85a7-4f5e-bd4e-34932c05de97

State: Peer in Cluster (Connected)

[root@gfs1 mnt]# gluster pool list

UUID                    Hostname            State

818cc628-85a7-4f5e-bd4e-34932c05de97    gfs2.cluster.com    Connected

dbcc01fc-3d2c-466f--57c46a9974be    localhost           Connected

volume和brick的概念

3.1 复制卷

Glusterfs初试-LMLPHP

创建GFS卷gv0并配置复制模式

mkdir -p /data/gluster/gv0（在gfs1和gfs2上都建立brick)

gluster volume create gv0 replica  gfs1.cluster.local:/data/gluster/gv0 gfs2.cluster.local:/data/gluster/gv0

启动gv0卷

gluster volume start gv0

gluster volume info gv0

[root@gfs1 mnt]# gluster volume info gv0

Volume Name: gv0

Type: Replicate

Volume ID: 26d05ac6---ada4-5a423793fa20

Status: Started

Snapshot Count:

Number of Bricks:  x  =

Transport-type: tcp

Bricks:

Brick1: gfs1.cluster.com:/data/gluster/gv0

Brick2: gfs2.cluster.com:/data/gluster/gv0

Options Reconfigured:

nfs.disable: on

transport.address-family: inet

3.2 分布式卷(Distributed volume)

Glusterfs初试-LMLPHP

mkdir -p /data/gluster/brick

gluster volume create gv1 gfs1.cluster.com:/data/gluster/brick gfs2.cluster.com:/data/gluster/brick

gluster volume start gv1

[root@gfs1 mnt]# mkdir -p /data/gluster/brick

[root@gfs1 mnt]# gluster volume create gv1 gfs1.cluster.com:/data/gluster/brick gfs2.cluster.com:/data/gluster/brick

volume create: gv1: success: please start the volume to access data

[root@gfs1 mnt]# gluster volume start gv1

volume start: gv1: success

[root@gfs1 mnt]# gluster volume info gv1

3.3 条带化卷(Stripe Volume)

Glusterfs初试-LMLPHP

mkdir -p /data/gluster/stripebrick

gluster volume create gv3 stripe  transport tcp gfs1.cluster.com:/data/gluster/stripebrick  gfs2.cluster.com:/data/gluster/stripebrick

gluster volume start gv3

[root@gfs1 mnt]# mkdir -p /data/gluster/stripebrick

[root@gfs1 mnt]# gluster volume create gv3 stripe  transport tcp gfs1.cluster.com:/data/gluster/stripebrick  gfs2.cluster.com:/data/gluster/stripebrick

[root@gfs1 mnt]# gluster volume info gv3

更详细拓扑结构和管理说明参考官方文档，值得你阅读

4.客户端配置

支持的客户端协议

Glusterfs初试-LMLPHP

yum install -y glusterfs-client

mkdir -p /mnt/glusterfs

mount -t glusterfs gfs1.cluster.com:/gv0 /mnt/glusterfs

验证挂载

[root@master ~]# df -hP /mnt/glusterfs

Filesystem             Size  Used Avail Use% Mounted on

gfs1.cluster.com:/gv0  .8G  136M  .2G   % /mnt/glusterfs

在node1和node2上也mount上glusterfs gv0,便于查看里面内容

[root@gfs1 ~]# mount -t glusterfs gfs2.cluster.com:/gv0 /mnt

[root@gfs2 ~]# mount -t glusterfs gfs1.cluster.com:/gv0 /mnt

然后基于客户端进行文件创建删除，同时将node1进行停机的高可用测试。
