GlusterFS 配置及使用【转】

作者:互联网

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主要特征

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}

do

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 \

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

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

Snapshot Count: 0

Number of Bricks: 3

Transport-type: tcp

Bricks:

Brick1: node1:/glusterfs/sdb/dv1

Brick2: node2:/glusterfs/sdb/dv1

Brick3: node3:/glusterfs/sdb/dv1

Options Reconfigured:

transport.address-family: inet

performance.readdir-ahead: on

nfs.disable: on

[root@node1 ~]# gluster volume set dis_vol nfs.disable off

volume set: success

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

[root@node7 ~]# df -h

文件系统             容量  已用  可用 已用% 挂载点

/dev/mapper/cl-root   18G  4.2G   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/sda1            297M  156M  142M   53% /boot

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

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

node3:/dis_vol       6.0G   97M  5.9G    2% /gfs_nfs

永久挂载

[root@node7 ~]# echo "node3:/dis_vol /gfs_nfs nfs defaults,_netdev 0 0" >> /etc/fstab

[root@node7 ~]# mount -a

[root@node7 ~]# df -h

文件系统             容量  已用  可用 已用% 挂载点
