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
[root@kvm200 ~]# vi /etc/sysconfig/network NETWORKING=yes HOSTNAME=kvm200.test.com
[root@kvm200 ~]# vi /etc/idmapd.conf [General] #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
[root@kvm200 ~]# hostname kvm200.test.com kvm200.test.com
[root@kvm200 ~]# 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
[root@kvm200 network-scripts]# 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
[root@kvm200 network-scripts]# 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
root@kvm200 network-scripts]# vi /etc/ntp.conf # Permit all access over the loopback interface. This could # be tightened as well, but to do so would effect some of # the administrative functions. restrict 127.0.0.1restrict -6 ::1restrict 0.0.0.0 mask 0.0.0.0 nomodify notrap noquery restrict 192.168.166.0 mask 255.255.255.0 nomodify# Hosts on local network are less restricted. #restrict 192.168.1.0 mask 255.255.255.0 nomodify notrap # Use public servers from the pool.ntp.org project. # Please consider joining the pool (http://www.pool.ntp.org/join.html). server 0.centos.pool.ntp.org iburst server 1.centos.pool.ntp.org iburst server 2.centos.pool.ntp.org iburst server 3.centos.pool.ntp.org iburstserver 210.72.145.44 prefer server 127.127.1.0 fudge 127.127.1.0 stratum 8 #图中红色部分的字体是新添加的。保存后重启ntp服务
[root@kvm200 ~]# service ntpd restart Shutting down ntpd: [ OK ] Starting ntpd: [ OK ]
客户端修改配置文件并手动同步:
[root@kvm201 ~]# vi /etc/ntp.conf ...... # Use public servers from the pool.ntp.org project. # Please consider joining the pool (http://www.pool.ntp.org/join.html). #server 0.centos.pool.ntp.org iburst #server 1.centos.pool.ntp.org iburst #server 2.centos.pool.ntp.org iburst #server 3.centos.pool.ntp.org iburst192.168.30.200 iburst #此处为ntp服务器的IP地址,要求能通信。如果不能通信则是服务器的iptables问题,后续我们将开放iptables端口。
[root@kvm201 ~]# service ntpd restart Shutting down ntpd: [ OK ] Starting ntpd: [ OK ]
[root@kvm201 ~]# ntpdate -u 192.168.30.200 #手动同步时间,或者等待系统自动同步也可,但等待时间可能较长,同步机制可谷歌NTP服务器介绍
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
root@kvm200 ~]# iptables -I INPUT 1 -s 10.10.0.0/16 -j ACCEPT [root@kvm200 ~]# service iptables save [root@kvm200 ~]# 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)
[root@kvm200 ~]# 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
[root@kvm200 ~]# cd /etc/yum.repos.d/ [root@kvm200 yum.repos.d]# wget http://download.gluster.org/pub/gluster/glusterfs/3.6/LATEST/CentOS/glusterfs-epel.repo [root@kvm200 yum.repos.d]# cd ~ [root@kvm200 ~]# wget http://download.fedora.redhat.com/pub/epel/6/x86_64/epel-release-6-5.noarch.rpm [root@kvm200 ~]# rpm -ivh epel-release-latest-6.noarch.rpm [root@kvm200 ~]# yum -y install glusterfs-server [root@kvm200 ~]# /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)
[root@kvm201 ~]# cd /etc/yum.repos.d/[root@kvm201 yum.repos.d]# wget -P [root@kvm201 yum.repos.d]# cd ~[root@kvm201 ~]# wget ftp://ftp.pbone.net/mirror/dl.iuscommunity.org/pub/ius/stable/CentOS/6/x86_64/epel-release-6-5.noarch.rpm [root@kvm201 ~]# rpm -ivh epel-release-6-8.noarch.rpm [root@kvm201 ~]# yum install glusterfs glusterfs-fuse glusterfs-server [root@kvm200 ~]# /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:
[root@kvm200 ~]# gluster peer probe 10.12.0.201 [root@kvm200 ~]# gluster peer probe 10.12.0.202 [root@kvm200 ~]# gluster volume create Mian stripe 2 10.12.0.201:/storage 10.12.0.202:/storage force [root@kvm200 ~]# 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。)
查看状态:
[root@kvm200 ~]# gluster volume status Status of volume: Mian Gluster process TCP Port RDMA Port Online Pid ------------------------------------------------------------------------------ Brick 10.12.0.200:/storage 49152 0 Y 3512 Brick 10.12.0.201:/storage 49152 0 Y 3417 Task Status of Volume Mian ------------------------------------------------------------------------------ There are no active volume tasks [root@kvm200 ~]# gluster peer status Number of Peers: 4Hostname: 10.12.0.204 Uuid: 23194295-4168-46d5-a0b3-8f06766c58b4 State: Peer in Cluster (Connected) Hostname: 10.12.0.202 Uuid: de10fd85-7b85-4f28-970b-339977a0bcf6 State: Peer in Cluster (Connected) Hostname: 10.12.0.201 Uuid: 0cd18fe2-62dd-457a-9365-a7c2c1c5c4b2 State: Peer in Cluster (Connected) Hostname: 10.12.0.203 Uuid: d160b7c3-89de-4169-b04d-bb18712d75c5 State: Peer in Cluster (Connected)
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!
