CentOS 6.5安装部署Glusterfs
环境介绍：Server:10.10.0.200 kvm200
Client1:10.10.0.201 kvm201
Client1:10.10.0.202 kvm202
1、首先部署Server端
主机名、网络配置、SELinux

# vi /etc/sysconfig/network
NETWORKING=yes
HOSTNAME=kvm200.test.com

# vi /etc/idmapd.conf
#Verbosity = 0# The following should be set to the local NFSv4 domain name
# The default is the host's DNS domain name.
Domain = test.com
1
2
# hostname kvm200.test.com
kvm200.test.com
1
2
# hostname --fqdn
kvm200.test.com
如果--fqdn能得到完整域名，即表示主机配置成功。
2、关闭SELinux

# vi /etc/sysconfig/selinux
# 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 - SELinux is fully disabled.
SELINUX=disabled #将此处设置为permissive或者disable都是可以的。
# SELINUXTYPE= type of policy in use. Possible values are:
# targeted - Only targeted network daemons are protected.
# strict - Full SELinux protection.
SELINUXTYPE=targeted
1
# setenforce 0 #立即生效
Client1、Client2同样操作设置主机名、Seliux
3、NTP服务器
如果你的server可以连网，并且可以同步时间，这个步骤可以忽略。如果是本地的环境，那则需要有一台NTP服务器，用来同步主机间的时间。
此处将kvm200设置为NTP服务器

NTP服务器搭建完成后。基本的环境配置已经完成。下面就是存储服务器的安装了、
4、IPtables防火墙设置以及修改挂载文件和创建挂载文件夹
4.1、修改每台防火墙设置为
1
2
3
root@kvm200 ~]# iptables -I INPUT 1 -s 10.10.0.0/16 -j ACCEPT
# service iptables save
# service iptables restart
4.2 修改挂载文件：/etc/fstab在此文件中最后添加两行（此处建设时已规划好，在后续就使用此文件夹来挂载存储系统）
1

3
# vi /etc/fstab
10.12.0.200:/Mian /primary glusterfs defaults,_netdev 0 0
4.3 存储服务器
搭建Gluster服务器之前，我们先配置Gluster源，之后去下载安装包

# cd /etc/yum.repos.d/
# wget http://download.gluster.org/pub/gluster/glusterfs/3.6/LATEST/CentOS/glusterfs-epel.repo
# cd ~
# wget http://download.fedora.redhat.com/pub/epel/6/x86_64/epel-release-6-5.noarch.rpm
# rpm -ivh epel-release-latest-6.noarch.rpm
# yum -y install glusterfs-server
# /etc/init.d/glusterfsd restart
安装完成之后，下面安装其它２台客户端：（注意：其它三台也需要先安装下面的才可以继续进行去。主要安装：glusterfs glusterfs-server glusterfs-fuse三个软件包）

# cd /etc/yum.repos.d/# wget -P
# cd ~# wget ftp://ftp.pbone.net/mirror/dl.iuscommunity.org/pub/ius/stable/CentOS/6/x86_64/epel-release-6-5.noarch.rpm
# rpm -ivh epel-release-6-8.noarch.rpm
# yum install glusterfs glusterfs-fuse glusterfs-server
# /etc/init.d/glusterfsd restart
上面的步骤做完后，我们回到kvm200机器上，将它们（200、201）加入gluster节点，并创建存储卷：
1
2
3
4
# gluster peer probe 10.12.0.201
# gluster peer probe 10.12.0.202
# gluster volume create Mian stripe 2 10.12.0.201:/storage 10.12.0.202:/storage force
# gluster volume start Mian
（如果加节点时报错，可能跟防火墙有关，请检查各个主机的防火墙设置。）

到此Glusterfs就已经全部部署完毕，使用mount在需要使用挂载的机器上进行挂载！
