?Gluster的模式及介紹在此不表，這里只記錄安裝及配置過程。

?

1.整體環境

server1 : gfs1.cluster.com?

server2 : gfs2.cluster.com?

?Client:?

2.安裝Gluster

• 下載軟件

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

下載?Red Hat Gluster Storage Server 3.4 on RHEL 7 Installation DVD

?

安裝RHEL 7.6的最小軟件安裝，將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

?

[rhel7.6] name=rhel7.6 baseurl=file:///repo/base/ enabled=1 gpgcheck=0

?

• 安裝

yum install -y redhat-storage-server systemctl start glusterd systemctl enable glusterd

systemctl status glusterd驗證一下

[root@gfs1 mnt]# systemctl status glusterd ● glusterd.service - GlusterFS, a clustered file-system serverLoaded: loaded (/usr/lib/systemd/system/glusterd.service; enabled; vendor preset: disabled)Active: active (running) since Fri 2019-02-08 16:06:17 CST; 6min agoProcess: 3145 ExecStart=/usr/sbin/glusterd -p /var/run/glusterd.pid --log-level $LOG_LEVEL $GLUSTERD_OPTIONS (code=exited, status=0/SUCCESS)Main PID: 3166 (glusterd)Tasks: 36CGroup: /system.slice/glusterd.service├─3166 /usr/sbin/glusterd -p /var/run/glusterd.pid --log-level INFO├─3640 /usr/sbin/glusterfs -s localhost --volfile-id gluster/glustershd -p /var/run/gluster/glustershd/glustershd.pid -l /var/lo...└─3899 /usr/sbin/glusterfsd -s gfs1.cluster.com --volfile-id gv0.gfs1.cluster.com.data-gluster-gv0 -p /var/run/gluster/vols/gv0/...Feb 08 16:06:06 gfs1.cluster.com systemd[1]: Starting GlusterFS, a clustered file-system server...

?

• 配置防火墻

簡單起見直接關閉了，以后補充開放具體網段

systemctl stop firewalld systemctl disable firewalld

?

• 修改主機名以及/etc/hosts

每臺機器執行，并修改/etc/hosts

hostnamectl set-hostname gfs1.cluster.com

?

• 添加存儲

在每臺glusterfs的server上加入一塊存儲盤，并進行初始化

fdisk /dev/sdb

?

?

mkfs.ext4 /dev/sdb1

?

在每個節點上運行以下命令掛載

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

在節點1上運行

gluster peer probe gfs2.cluster.com

驗證

[root@gfs1 mnt]# gluster peer status Number of Peers: 1Hostname: 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-9283-57c46a9974be localhost Connected

volume和brick的概念

?

?

?

?

3.1 復制卷

?

創建GFS卷gv0并配置復制模式

?

mkdir -p /data/gluster/gv0（在gfs1和gfs2上都建立brick) gluster volume create gv0 replica 2 gfs1.cluster.local:/data/gluster/gv0 gfs2.cluster.local:/data/gluster/gv0

?

啟動gv0卷

gluster volume start gv0 gluster volume info gv0 [root@gfs1 mnt]# gluster volume info gv0Volume Name: gv0 Type: Replicate Volume ID: 26d05ac6-0415-4041-ada4-5a423793fa20 Status: Started Snapshot Count: 0 Number of Bricks: 1 x 2 = 2 Transport-type: tcp Bricks: Brick1: gfs1.cluster.com:/data/gluster/gv0 Brick2: gfs2.cluster.com:/data/gluster/gv0 Options Reconfigured: performance.client-io-threads: off nfs.disable: on transport.address-family: inet

?

3.2 分布式卷(Distributed volume)

?

mkdir -p /data/gluster/brickgluster volume create gv1 gfs1.cluster.com:/data/gluster/brick gfs2.cluster.com:/data/gluster/brickgluster 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 gv1Volume Name: gv1 Type: Distribute Volume ID: 4782dd87-a411-44b3-8621-70dfb072b5d0 Status: Started Snapshot Count: 0 Number of Bricks: 2 Transport-type: tcp Bricks: Brick1: gfs1.cluster.com:/data/gluster/brick Brick2: gfs2.cluster.com:/data/gluster/brick Options Reconfigured: transport.address-family: inet nfs.disable: on

?

3.3 條帶化卷(Stripe Volume)

?

mkdir -p /data/gluster/stripebrickgluster volume create gv3 stripe 2 transport tcp gfs1.cluster.com:/data/gluster/stripebrick gfs2.cluster.com:/data/gluster/stripebrickgluster volume start gv3

?

[root@gfs1 mnt]# mkdir -p /data/gluster/stripebrick [root@gfs1 mnt]# gluster volume create gv3 stripe 2 transport tcp gfs1.cluster.com:/data/gluster/stripebrick gfs2.cluster.com:/data/gluster/stripebrick volume create: gv3: success: please start the volume to access data [root@gfs1 mnt]# gluster volume start gv3 volume start: gv3: success [root@gfs1 mnt]# gluster volume info gv3Volume Name: gv3 Type: Stripe Volume ID: c25a10b8-a943-4c40-93be-088b972cbbaa Status: Started Snapshot Count: 0 Number of Bricks: 1 x 2 = 2 Transport-type: tcp Bricks: Brick1: gfs1.cluster.com:/data/gluster/stripebrick Brick2: gfs2.cluster.com:/data/gluster/stripebrick Options Reconfigured: transport.address-family: inet nfs.disable: on

?

3.4 分布式復制卷

?

?

更詳細拓撲結構和管理說明參考官方文檔，值得你閱讀

https://access.redhat.com/documentation/en-us/red_hat_gluster_storage/3/html/administration_guide/

?

4.客戶端配置

支持的客戶端協議

?

yum install -y glusterfs-client mkdir -p /mnt/glusterfs mount -t glusterfs gfs1.cluster.com:/gv0 /mnt/glusterfs

驗證掛載

[root@master ~]# df -hP /mnt/glusterfs Filesystem Size Used Avail Use% Mounted on gfs1.cluster.com:/gv0 9.8G 136M 9.2G 2% /mnt/glusterfs

在node1和node2上也mount上glusterfs gv0,便于查看里面內容

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

然后基于客戶端進行文件創建刪除，同時將node1進行停機的高可用測試。
