GPFS的安装与配置

一.准备工作

1.首先配置ssh无密码登陆

2.修改/etc/hosts文件

4.硬件要求(必须要有额外的磁盘)

拓扑图如下:

1.首先我们来配置ssh无密码:

node1:

ssh-keygen-N ""
ssh-copy-id-i ~/.ssh/id_rsa.pub node2

输入密码即可

node2:

ssh-keygen-N ""
ssh-copy-id-i ~/.ssh/id_rsa.pub node1

输入密码即可

2.修改hosts文件

vim/etc/hosts

192.168.199.10    node1
192.168.199.11    node2

二.安装GPFS。

1.把软件包上传到服务器(略)

2.在服务器各个节点创建挂载目录(略)

3.把时间调成一样,不联网就手工改date092610372013

4.安装依赖包，GPFS软件包补丁包，并进行配置

使用yum安装所需软件包:(node1,node2同样操作,下面只演示一台)

yum install kernel-headers kernel-devellibstdc++.so.5 compat-libstdc++-33.x86_64 glibc-devel gcc libXp.so.6 imakegcc-c++ rpm-build ksh rsh -y

安装gpfs包

rpm -ivh gpfs.*

cd update/

rpm -Uvh gpfs.*

cd/usr/lpp/mmfs/src
makeAutoconfig
makeWorld
makeInstallImages

添加全局环境变量，让环境变量生效。

echoexport PATH=$PATH:/usr/lpp/mmfs/bin >>/etc/profile
./etc/profile

cd/tmp/gpfs (安装包在这个文件里)
mkdirconfig
touchcluster.cfg
vimcluster.cfg
node1:quorum-manager
node2:quorum-manager

mmcrcluster-N cluster.cfg -p node1 -s node2 -r /usr/bin/ssh -R /usr/bin/scp -C Symphony

允许全部

mmchlicenseserver --accept -N all

定义磁盘nsd:

touchnsd.cfg
vimnsd.cfg
/dev/sdb:node1:::1:nsd1:
/dev/sdb:node2:::2:nsd2:
mmcrnsd-F nsd.cfg

mmlsconfig> mmlsconfig.cfg

mmlsconfig
mmchconfigpagepool=512M
mmchconfignsdMaxWorkerThreads=800
mmchconfigmaxInodeDeallocPrefetch=32
mmchconfigworker1Threads=400
mmchconfigmaxReceiverThreads=32
mmchconfignsdThreadsPerDisk=60
mmchconfigreadReplicaPolicy=local
mmchconfigprefetchAggressivenessWrite=0
mmchconfigsyncBuffsPerIteration=1

启动GPFS

mmstartup -a

查看各个节点状态:

mmgetstate -Lsa

挂载:

mmmount all -a
