glusterfs创建分布式卷

一、环境信息

node1 192.168.8.11 两块磁盘
node2 192.168.8.12 两块磁盘

二、通用配置（各个节点）

1、修改主机名

hostnamectl set-hostname node1

2、修改hosts文件

# cat <<"EOF">/etc/hosts
127.0.0.1 localhost localhost.localdomain localhost4 localhost4.localdomain4
::1 localhost localhost.localdomain localhost6 localhost6.localdomain6
192.168.8.11 node1
192.168.8.12 node2
EOF

3、配置源

# cat <<END >/etc/yum.repos.d/repo.repo
[repo]
name=repo
baseurl = https://mirrors.tuna.tsinghua.edu.cn/centos/7/storage/x86_64/gluster-6/
enabled=1
gpgcheck=0
END

4、安装NTP（各个节点）

# yum -y install ntp

修改配置文件/etc/ntp.conf

server <NTP-server>

**注意： **
NTP-server修改为自己的NTP服务器，如果局域网内无NTP服务器，此处可以用默认配置，采用centos官方ntp服务器

5、启动ntpd服务并设置开机启动

# systemctl start ntpd
# systemctl enable ntpd

查看ntp状态

# ntpq -p

6、配置防火墙

# firewall-cmd --add-service=ntp --permanent
success
# firewall-cmd --reload
success

7、安装软件包

# yum -y install glusterfs-server

8、启动服务并设置开机启动

# systemctl start glusterd

# systemctl enable glusterd

9、查看版本

# gluster --version
glusterfs 6.4

10、配置防火墙

# firewall-cmd --add-service=glusterfs --permanent
success
# firewall-cmd --reload

三、配置存储

1、创建lvm卷

# vgcreate data /dev/vdb
# lvcreate --name lv -l +100%FREE data

2、格式化lvm逻辑卷

# mkfs.xfs /dev/data/lv -f

3、创建目录

# mkdir -p /glusterfs/data

4、修改/etc/fstab文件（挂载第一层目录，第二层data目录用于创建gluster用）

/dev/mapper/data-lv /glusterfs xfs defaults 0 0

5、挂载目录

mount -a

6、检查

# df -h
Filesystem Size Used Avail Use% Mounted on
/dev/mapper/centos-root 77G 1.2G 76G 2% /
devtmpfs 3.9G 0 3.9G 0% /dev
tmpfs 3.9G 0 3.9G 0% /dev/shm
tmpfs 3.9G 8.5M 3.9G 1% /run
tmpfs 3.9G 0 3.9G 0% /sys/fs/cgroup
/dev/vda1 1014M 142M 873M 14% /boot
/dev/mapper/data-lv 200G 181G 20G 91% /glusterfs
tmpfs 783M 0 783M 0% /run/user/0

四、创建和配置集群（在一台配置即可）

1、配置集群

# gluster peer probe node2

2、查看状态

# gluster peer status

3、创建卷（这个要写第二层目录/glusterfs/data要不会报错）

# gluster volume create vol_data transport tcp \
node1:/glusterfs/data \
node2:/glusterfs/data
volume create: data: success: please start the volume to access data

创建复制卷

gluster volume create rep_vol replica 2 192.168.8.11:/glusterfs/data 192.168.8.12:/glusterfs/data

4、启动卷

# gluster volume start vol_data
volume start: vol_data: success

5、查看详细信息

# gluster volume info
Volume Name: vol_data
Type: Distribute
Volume ID: 877b1de0-d8d1-49d4-958c-b1f455dbe7d5
Status: Started
Snapshot Count: 0
Number of Bricks: 2
Transport-type: tcp
Bricks:
Brick1: node1:/glusterfs/data
Brick2: node2:/glusterfs/data
Options Reconfigured:
transport.address-family: inet
nfs.disable: on

GlusterFS集群创建

一、简介

GlusterFS概述

Glusterfs是一个开源的分布式文件系统,是Scale存储的核心,能够处理千数量级的客户端.在传统的解决方案中Glusterfs能够灵活的结合物理的,虚拟的和云资源去体现高可用和企业级的性能存储.
Glusterfs通过TCP/IP或InfiniBand RDMA网络链接将客户端的存储资块源聚集在一起,使用单一的全局命名空间来管理数据,磁盘和内存资源.
Glusterfs基于堆叠的用户空间设计,可以为不同的工作负载提供高优的性能.
Glusterfs支持运行在任何标准IP网络上标准应用程序的标准客户端，如下图1所示，用户可以在全局统一的命名空间中使用NFS/CIFS等标准协议来访问应用数据.

Glusterfs主要特征

扩展性和高性能
高可用
全局统一命名空间
弹性hash算法
弹性卷管理
基于标准协议

工作原理：

1) 首先是在客户端，用户通过glusterfs的mount point 来读写数据，对于用户来说，集群系统的存在对用户是完全透明的，用户感觉不到是操作本地系统还是远端的集群系统。
2) 用户的这个操作被递交给本地linux系统的VFS来处理。
3) VFS 将数据递交给FUSE 内核文件系统:在启动 glusterfs 客户端以前，需要想系统注册一个实际的文件系统FUSE,如上图所示，该文件系统与ext3在同一个层次上面， ext3 是对实际的磁盘进行处理，而fuse 文件系统则是将数据通过/dev/fuse 这个设备文件递交给了glusterfs client端。所以，我们可以将 fuse文件系统理解为一个代理。
4) 数据被fuse 递交给Glusterfs client 后， client 对数据进行一些指定的处理（所谓的指定，是按照client 配置文件据来进行的一系列处理，我们在启动glusterfs client 时需要指定这个文件。
5) 在glusterfs client的处理末端，通过网络将数据递交给 Glusterfs Server，并且将数据写入到服务器所控制的存储设备上。

常用卷类型

分布（distributed）

复制（replicate）

条带（striped）

基本卷：

(1) distribute volume：分布式卷

(2) stripe volume：条带卷

(3) replica volume：复制卷

复合卷：

(4) distribute stripe volume：分布式条带卷

(5) distribute replica volume：分布式复制卷

(6) stripe replica volume：条带复制卷

(7) distribute stripe replicavolume：分布式条带复制卷

二、环境规划

注：node1-node6 为服务端，node-client为客户端

操作系统	IP	主机名	硬盘数量（三块）
centos 7.3	172.16.2.51	node1	sdb:2G sdc:2G sdd:2G
centos 7.3	172.16.2.52	node2	sdb:2G sdc:2G sdd:2G
centos 7.3	172.16.2.53	node3	sdb:2G sdc:2G sdd:2G
centos 7.3	172.16.2.54	node4	sdb:2G sdc:2G sdd:2G
centos 7.3	172.16.2.55	node5	sdb:2G sdc:2G sdd:2G
centos 7.3	172.16.2.56	node6	sdb:2G sdc:2G sdd:2G
centos 7.3	172.16.2.57	node7-client	sda:20G

1、环境准备：(node1-node6 同时操作)

1.1 给node1-node6 每台主机添加三块各2G硬盘。

[root@node1 ~]# df -h

文件系统容量已用可用已用% 挂载点

/dev/mapper/cl-root 18G 4.2G 14G 24% /

devtmpfs 473M 0 473M 0% /dev

tmpfs 489M 84K 489M 1% /dev/shm

tmpfs 489M 7.1M 482M 2% /run

tmpfs 489M 0 489M 0% /sys/fs/cgroup

/dev/sdd 2.0G 33M 2.0G 2% /glusterfs/sdd

/dev/sdc 2.0G 33M 2.0G 2% /glusterfs/sdc

/dev/sdb 2.0G 33M 2.0G 2% /glusterfs/sdb

/dev/sda1 297M 158M 140M 54% /boot

tmpfs 98M 16K 98M 1% /run/user/42

tmpfs 98M 0 98M 0% /run/user/0

1.2 关闭防火墙，seLinux，同步时间

关闭防火墙

systemctl stop firewalld

systemctl disable firewalld

关闭SELinux

sed 's/=permissive/=disabled/' /etc/selinux/config

setenforce 0

同步时间

ntpdate ntp.gwadar.cn

1.3 主机解析（hosts文件配置)

[root@node1 ~]# cat /etc/hosts

127.0.0.1 localhost localhost.localdomain localhost4 localhost4.localdomain4

::1 localhost localhost.localdomain localhost6 localhost6.localdomain6

172.16.2.51 node1

172.16.2.52 node2

172.16.2.53 node3

172.16.2.54 node4

172.16.2.55 node5

172.16.2.56 node6

1.4 测试所有存储节点网络情况

for i in {1..6}

ping -c3 node$i &> /dev/null && echo "$i up "

done

1.5 配置epel源

yum install http://mirrors.163.com/centos/7.3.1611/extras/x86_64/Packages/epel-release-7-9.noarch.rpm

1.6 配置glusterfs 的本地 yum源（采用网络源方式）

vim /etc/yum.repos.d/gluster-epel.repo

[root@node1 ~]# cat /etc/yum.repos.d/gluster.repo

[gluster]

name=gluster

baseurl=https://buildlogs.centos.org/centos/7/storage/x86_64/gluster-3.8/

gpgcheck=0

enabled=1

1.7 安装GlusterFS和rpcbind(他是一个RPC服务，主要是在nfs共享时候负责通知客户端，服务器的nfs端口号的。简单理解rpc就是一个中介服务。)

yum install -y glusterfs-server samba rpcbind

systemctl start glusterd.service

systemctl enable glusterd.service

systemctl start rpcbind // rpcbind 用于以nfs方式挂在

systemctl enable rpcbind

systemctl status rpcbind

以上操作均在node1-node6上同时操作

三、Gluster管理

1、gluster 命令帮助

[root@node1 ~]# gluster peer help

peer detach { <HOSTNAME> | <IP-address> } [force] - detach peer specified by <HOSTNAME>

peer help - Help command for peer

peer probe { <HOSTNAME> | <IP-address> } - probe peer specified by <HOSTNAME>

peer status - list status of peers

pool list - list all the nodes in the pool (including localhost)

2、添加GlusterFS节点（在node1上操作就可以）

[root@node1 ~]# gluster peer probe node2

peer probe: success.

[root@node1 ~]# gluster peer probe node3

peer probe: success.

[root@node1 ~]# gluster peer probe node4

peer probe: success.

查看所添加节点的状态

[root@node1 ~]# gluster peer status

Number of Peers: 3

Hostname: node2

Uuid: 67c60312-a312-43d6-af77-87cbbc29e1aa

State: Peer in Cluster (Connected)

Hostname: node3

Uuid: d79c3a0b-585a-458d-b202-f88ac1439d0d

State: Peer in Cluster (Connected)

Hostname: node4

Uuid: 97094c6e-afc8-4cfb-9d26-616aedc55236

State: Peer in Cluster (Connected)

从存储池中删除节点

[root@node1 ~]# gluster peer detach node2

peer detach: success

[root@node1 ~]# gluster peer probe node2

peer probe: success.

3、创建卷

3.1创建分布卷

[root@node1 ~]# gluster volume create dis_vol \

> node1:/glusterfs/sdb/dv1 \

> node2:/glusterfs/sdb/dv1 \

> node3:/glusterfs/sdb/dv1

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

查看分布卷

[root@node1 ~]# gluster volume info dis_vol

3.2创建复制卷

[root@node1 ~]# gluster volume create rep_vol replica 3 \

> node1:/glusterfs/sdb/rv2 \

> node2:/glusterfs/sdb/rv2 \

> node3:/glusterfs/sdb/rv2

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

查看

[root@node1 ~]# gluster volume info rep_vol

3.3创建条带卷

[root@node1 ~]# gluster volume create str_vol stripe 3 \

> node1:/glusterfs/sdb/sv3 \

> node2:/glusterfs/sdb/sv3 \

> node3:/glusterfs/sdb/sv3

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

查看gluster volume info str_vol

3.4 创建分布条带卷

[root@node1 ~]# gluster volume create dir_str_vol stripe 4 \

> node1:/glusterfs/sdb/dsv4 \

> node2:/glusterfs/sdb/dsv4 \

> node3:/glusterfs/sdb/dsv4 \

> node4:/glusterfs/sdb/dsv4 \

> node5:/glusterfs/sdb/dsv4 \

> node6:/glusterfs/sdb/dsv4 \

> node1:/glusterfs/sdc/dsv4 \

> node2:/glusterfs/sdc/dsv4

volume create: dir_str_vol: failed: Host node5 is not in ' Peer in Cluster' state

3.5 创建分布复制卷

[root@node1 ~]# gluster volume create dir_rep_vol replica 2 \

> node2:/glusterfs/sdb/drv5 \

> node1:/glusterfs/sdb/drv5 \

> node3:/glusterfs/sdb/drv5 \

> node4:/glusterfs/sdb/drv5

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

3.6 创建分布条带复制

> node3:/glusterfs/sdb/drsv6 \

> node4:/glusterfs/sdb/drsv6

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

3.7 创建条带复制卷

[root@node1 ~]# gluster volume create str_rep_vol stripe 2 replica 2 \

> node1:/glusterfs/sdb/srv7 \

> node2:/glusterfs/sdb/srv7 \

> node3:/glusterfs/sdb/srv7 \

> node4:/glusterfs/sdb/srv7

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

3.8 创建分散卷（不常用）

> node1:/glusterfs/sdb/dv8 \

> node2:/glusterfs/sdb/dv8 \

> node3:/glusterfs/sdb/dv8 \

> node4:/glusterfs/sdb/dv8

There isn't an optimal redundancy value for this configuration. Do you want to create the volume with redundancy 1 ? (y/n) y

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

查看卷的状态

7、迁移卷(替换)

volume replace-brick <VOLNAME> <SOURCE-BRICK> <NEW-BRICK> {commit force}

示例：

[root@node1 ~]# gluster volume replace-brick rep_vol node2:/glusterfs/sdb/rv2 node2:/glusterfs/sdb/rv3 commit force

volume replace-brick: failed: volume: rep_vol is not started

[root@node1 ~]# gluster volume start rep_vol

volume start: rep_vol: success

[root@node1 ~]# gluster volume replace-brick rep_vol node2:/glusterfs/sdb/rv2 node2:/glusterfs/sdb/rv3 commit force

volume replace-brick: success: replace-brick commit force operation successful

#迁移需要完成一系列的事务，假如我们准备将mamm卷中的brick3替换为brick5
#启动迁移过程
$gluster volume replace-brick mamm-volume node3:/exp3 node5:/exp5 start
#暂停迁移过程
$gluster volume replace-brick mamm-volume node3:/exp3 node5:/exp5 pause
#中止迁移过程
$gluster volume replace-brick mamm-volume node3:/exp3 node5:/exp5 abort
#查看迁移状态
$gluster volume replace-brick mamm-volume node3:/exp3 node5:/exp5 status
#迁移完成后提交完成
$gluster volume replace-brick mamm-volume node3:/exp3 node5:/exp5 commit

四、客户端管理

1、安装

[root@node7-client ~]# yum install glusterfs glusterfs-fuse attr -y

2、glusterfs方式挂在

挂载（当前生效）

[root@node7 ~]# mount -t glusterfs node2:/rep_vol /gfs_test/

[root@node7 ~]# df -h

文件系统容量已用可用已用% 挂载点

/dev/mapper/cl-root 18G 4.1G 14G 24% /

devtmpfs 473M 0 473M 0% /dev

tmpfs 489M 84K 489M 1% /dev/shm

tmpfs 489M 7.1M 482M 2% /run

tmpfs 489M 0 489M 0% /sys/fs/cgroup

/dev/sda1 297M 156M 142M 53% /boot

tmpfs 98M 16K 98M 1% /run/user/42

tmpfs 98M 0 98M 0% /run/user/0

node2:/rep_vol 2.0G 33M 2.0G 2% /rep

node2:/rep_vol 2.0G 33M 2.0G 2% /gfs_test

挂载（永久）

[root@node7 ~]# echo "node2:/rep_vol /gfs_test glusterfs defaults,_netdev 0 0" >> /etc/fstab

[root@node7 ~]# mount -a

3、Nfs方式

挂在（当前生效）

[root@node7 ~]# mount -t nfs node3:/dis_vol gfs_nfs

mount.nfs: requested NFS version or transport protocol is not supported

解决方法：

1）、安装 nfs-utils rpcbind

2）、开起卷的nfs挂载方式

[root@node1 ~]# gluster volume info dis_vol

Volume Name: dis_vol

Type: Distribute

Volume ID: c501f4ad-5a54-4835-b163-f508aa1c07ba

Status: Started
