《Gluster集羣搭建-centos7.2環境》
（1）解壓安裝包：glusterfs-3.8-release.zip
（2）進入安裝目錄：
執行安裝腳本
./install.sh
安裝完成！
（3）關閉防火牆（所有節點上執行）：
[root@client ~]# service iptables status // 查看防火牆狀態
[root@client ~]# service iptables stop // 簡單關閉
（4）關閉SELinux（所有節點上執行）：
[root@client ~]# getenforce // 查看SELiunx的狀態
Enforcing
[root@client ~]# setenforce 0 // 設置當前爲關閉
[root@client ~]# getenforce // 查看一下狀態
Permissive
[root@client ~]# vi /etc/selinux/config // 設置開機不啓動
[root@client ~]# cat /etc/selinux/config
# This file controls the state of SELinux on the system.
# SELINUX= can take one of these three values:
# enforcing - SELinux security policy is enforced.
# permissive - SELinux prints warnings instead of enforcing.
# disabled - No SELinux policy is loaded.
SELINUX=disabled
# SELINUXTYPE= can take one of these two values:
# targeted - Targeted processes are protected,
# mls - Multi Level Security protection.
SELINUXTYPE=targeted
[root@client ~]#
（5）設置ip主機名映射文件：
[root@localhost ~]# vi /etc/hosts // 編輯hosts文件夾
將以下內容填寫到配置文件中：
192.168.220.135 client
192.168.220.136 server01
192.168.220.137 server02
192.168.220.138 server03
192.168.220.139 server04
當然，這個是根據你自己的虛擬機IP地址確定的配置信息。
將hosts文件拷貝到其他機器中，記得輸入yes和密碼
[root@localhost ~]# scp /etc/hosts root@server01:/etc/hosts
The authenticity of host 'server01 (192.168.220.136)' can't be established.
RSA key fingerprint is 1b:f9:32:57:5a:df:9c:f5:58:e1:cd:1f:2c:9f:07:75.
Are you sure you want to continue connecting (yes/no)? yes
Warning: Permanently added 'server01,192.168.220.136' (RSA) to the list of known hosts.
root@server01's password:
hosts 100% 282 0.3KB/s 00:00
[root@localhost ~]#
同理將/etc/hosts拷貝至其它節點：
scp /etc/hosts root@server02:/etc/hosts
scp /etc/hosts root@server03:/etc/hosts
scp /etc/hosts root@server04:/etc/hosts
（6）設置開機自啓（每個節點上）：
啓動Gluster服務
[root@localhost glusterfs-3.4.2]# /etc/init.d/glusterd status // 查看服務是否啓動
glusterd is stopped
[root@localhost glusterfs-3.4.2]# /etc/init.d/glusterd start // 啓動服務
Starting glusterd: [ OK ]
[root@localhost glusterfs-3.4.2]#
[root@localhost glusterfs-3.4.2]# chkconfig glusterd on // 設置服務開機自動啓動
[root@localhost glusterfs-3.4.2]#
（7）加入集羣節點（在server1上執行）
[root@server01 ~]# gluster peer probe server02
peer probe: success
[root@server01 ~]# gluster peer probe server03
peer probe: success
[root@server01 ~]# gluster peer probe server04
peer probe: success
（7.1）查看集羣中加入的節點：
[root@server01 ~]# gluster peer status
Number of Peers: 3
Hostname: server02
Port: 24007
Uuid: e3b697dd-428d-4c15-85b5-0bbd3dba1ef6
State: Peer in Cluster (Connected)
Hostname: server03
Port: 24007
Uuid: 0d61b1c9-9e98-4fec-b9ef-4add193009f6
State: Peer in Cluster (Connected)
Hostname: server04
Port: 24007
Uuid: 57144cf3-2d3a-437d-9391-293390a85d9a
State: Peer in Cluster (Connected)
[root@server01 ~]#
顯示全部連接成功！
（8） 創建一個分佈式卷
首先在四臺機器上創建一個能夠存放文件系統的文件夾
[root@server01 ~]# mkdir /Data
[root@server02 ~]# mkdir /Data
[root@server03 ~]# mkdir /Data
[root@server04 ~]# mkdir /Data
[root@server01 ~]# gluster volume create dht server01:/Data/dht1 server02:/Data/dht2 server03:/Data/dht3 server04:/Data/dht4 force // 創建一個分佈式卷dht
volume create: dht: success: please start the volume to access data
[root@server01 ~]# gluster volume start dht // 啓動這個分佈式卷
volume start: dht: success
[root@server01 ~]# gluster volume status dht // 查看這個卷的情況
Status of volume: dht
Gluster process Port Online Pid
------------------------------------------------------------------------------
Brick server01:/Data/dht1 49152 Y 1610
Brick server02:/Data/dht2 49152 Y 1554
Brick server03:/Data/dht3 49152 Y 1532
Brick server04:/Data/dht4 49152 Y 1549
NFS Server on localhost 2049 Y 1620
NFS Server on server02 2049 Y 1564
NFS Server on server03 2049 Y 1542
NFS Server on server04 2049 Y 1559
There are no active volume tasks
[root@server01 ~]#
（9） 掛載分佈式卷（在任意節點上執行）
[root@server01 ~]# mount -t glusterfs server01:/dht /mnt/ // 掛在server01捲到server01的mnt路徑下
[root@server01 ~]#
[root@server01 ~]# df –h // 查看磁盤大小
Filesystem Size Used Avail Use% Mounted on
/dev/mapper/VolGroup-lv_root
18G 1003M 16G 7% /
tmpfs 491M 0 491M 0% /dev/shm
/dev/sda1 477M 52M 400M 12% /boot
server01:/dht 69G 4.0G 62G 7% /mnt
[root@server01 ~]#
（10） 測試卷
[root@server01 mnt]# touch file{001..010} // 創建十個文件
[root@server01 mnt]# ls
file001 file002 file003 file004 file005 file006 file007 file008 file009 file010
[root@server01 mnt]#
在集羣機器上查看文件分佈情況：
[root@server01 Data]# cd dht1/
[root@server01 dht1]# ls
file002 file004 file005 file008 file009
[root@server01 dht1]#
[root@server02 Data]# cd dht2/
[root@server02 dht2]# ls
file010
[root@server02 dht2]#
[root@server03 Data]# cd dht3/
[root@server03 dht3]# ls
file003 file006
[root@server03 dht3]#
[root@server04 Data]# cd dht4/
[root@server04 dht4]# ls
file001 file007
[root@server04 dht4]#
