目錄(?)[+]
xcat非常方便，hp有cmu，當(dāng)然那個(gè)是花錢(qián)的，xcat是ibm前兩年開(kāi)源的一個(gè)軟件，功能可以說(shuō)還是夠強(qiáng)大的。
1、先刪除掉沖突軟件
xCAT2和操作系統(tǒng)的載OpenIPMI-tools和tftpserver不兼容，需要把這兩個(gè)包刪除。
同時(shí)bind-chroot和dhcp-chroot軟件包如果存在也會(huì)導(dǎo)致問(wèn)題，需要?jiǎng)h除。
# rpm -e --nodeps??tftp-server-0.49-2
2、xCAT2軟件安裝
創(chuàng)建xcat的yum安裝源
把xcat上傳到服務(wù)器，本例是/root /xcat/
# cd /root/xcat/
# ls
xcat-core-2.6.1.tar.bz2??xcat-dep-201105100946.tar.bz2
# tar -xjvfxcat-core-2.6.1.tar.bz2
# tar -xjvfxcat-dep-201105100946.tar.bz2
1）創(chuàng)建xcat-core的yum安裝源
# cd xcat-core
#./mklocalrepo.sh
2)創(chuàng)建xcat-dep的yum安裝源
#cd ../xcat-dep/rh5/x86_64
#./mklocalrepo.sh
?
安裝xCAT
# yum install xCAT
根據(jù)提示進(jìn)行安裝即可.
默認(rèn)安裝到/opt/xcat目錄中
測(cè)試
#source /etc/profile.d/xcat.sh
#tabdump?將列出xcat所有可配置的表。讀取site表

設(shè)置networks表
先查看一下networks表
[root@manager1 yum.repos.d]#tabdump networks
#netname,net,mask,mgtifname,gateway,dhcpserver,tftpserver,nameservers,ntpservers,logservers,dynamicrange,nodehostname,ddnsdomain,vlanid,comments,disable

按環(huán)境改
# chtab net=172.16.1.0networks.dhcpserver=172.16.1.1
# chtab net=172.16.1.0networks.ntpservers=172.16.1.1
# chtab net=172.16.1.0 networks.logservers=172.16.1.1
# chtab net=172.16.1.0networks.tftpserver=172.16.1.1
使用這類(lèi)命令來(lái)設(shè)置，建議
netname,net,mask,mgtifname,dhcpserver,tftpserver,nameservers,ntpservers,logservers這些都設(shè)置上。
注意：
當(dāng)不設(shè)置dynamicrange這個(gè)字段時(shí)，系統(tǒng)可以按照mac地址一對(duì)一的分配IP地址。不過(guò)在makedhcp時(shí)會(huì)有一條告警，不用管它。（建議方式）
設(shè)置dynamicrange這個(gè)字段時(shí)，系統(tǒng)不能按照mac地址一對(duì)一的分配IP地址。（在集群連接用戶(hù)現(xiàn)有網(wǎng)絡(luò)時(shí)，可能會(huì)產(chǎn)生災(zāi)難性的后果
設(shè)置passwd密碼表
#chtab key=systempasswd.username=root passwd.password=root123（用于每個(gè)xcat安裝出來(lái)的節(jié)點(diǎn)）
#chtab key=bladepasswd.username=USERID passwd.password=PASSW0RD（對(duì)應(yīng)刀箱的AMM管理模塊）
#chtab key=ipmipasswd.username=USERID passwd.password=PASSW0RD（對(duì)應(yīng)機(jī)架式服務(wù)器的IMM管理模塊）

servicenode,tftpserver,nfsserver,monserver,installnic,primarynic,xcatmaster
discoverynics可根據(jù)具體環(huán)境，不是必須。建議配置以上服務(wù)
設(shè)置nodetype表
[root@manager1 yum.repos.d]#tabdump nodetype
#node,os,arch,profile,provmethod,supportedarchs,nodetype,comments,disable
"ON001","rhels5u5","x86_64","compute",,,,,
"ON002","rhels5u5","x86_64","compute",,,,,
。。。。。。
"ON126","rhels5u5","x86_64","compute",,,,,
"ON127","rhels5u5","x86_64","jss",,,,,
"ON128","rhels5u5","x86_64","oracle",,,,,
#chtab node=節(jié)點(diǎn)名nodetype.os=rhels5u5 nodetype.arch=x86_64 nodetype.profile=compute nodetype.nodetype=osi
在nodetype表中，定義計(jì)算節(jié)點(diǎn)ON001-ON126的操作系統(tǒng)是rhels5.5
x86_64，使用的profile是compute，節(jié)點(diǎn)類(lèi)型是osi(OS image)
注意這里的nodetype.os、nodetype.profile這兩個(gè)字段和kickstart文件名關(guān)聯(lián)，如上設(shè)置，則：
kickstart文件名為：compute.rhels5u5.tmpl
kickstart軟件包列表的文件名為：compute.rhels5u5.pkglist
compute.tmpl+compute.pkglist?存放位置
/opt/xcat/share/xcat/install/rh
設(shè)置postscripts表
這個(gè)表指定在kickstart安裝前，rpm包安裝后和安裝完成后第一次啟動(dòng)時(shí)執(zhí)行的腳本，不同集群的環(huán)境定制全都在這里做。
[root@manager1 etc]# tabdumppostscripts
#node,postscripts,postbootscripts,comments,disable
"xcatdefaults","syslog,remoteshell,syncfiles,setupntp","otherpkgs",,
"service","servicenode,xcatserver,xcatclient",,,
"compute","hardeths,configRSH,configService",,,
postscripts這列表示rpm包安裝后后執(zhí)行。
postbootscripts這列表示安裝完成后第一次啟動(dòng)時(shí)執(zhí)行的腳本。
其中,xcatdefaults和service這兩段為系統(tǒng)默認(rèn)就有
xcatdefaults這個(gè)段代表所有節(jié)點(diǎn)都要執(zhí)行的腳本
service是服務(wù)節(jié)點(diǎn)需要執(zhí)行的腳本，服務(wù)節(jié)點(diǎn)是在較大（也許256節(jié)點(diǎn)以上）的集群環(huán)境中配置的，主要是分擔(dān)管理節(jié)點(diǎn)的壓力。
所有腳本位于/install/postscripts目錄下
xcatdefaults默認(rèn)的postscripts為"syslog,remoteshell,syncfiles"。
1）syslog腳本把各節(jié)點(diǎn)的log重定向到管理節(jié)點(diǎn)。
2）remoteshell腳本設(shè)置ssh無(wú)密碼互通。注意xcat默認(rèn)情況下root從管理節(jié)點(diǎn)ssh到各被管節(jié)點(diǎn)ssh無(wú)密碼，但是從被管節(jié)點(diǎn)ssh到管理節(jié)點(diǎn)是要密碼的。
3）syncfiles腳本指定安裝過(guò)程中要同步的文件。但還需要其他相關(guān)配置，詳細(xì)后面說(shuō)明。
xcatdefaults默認(rèn)的postscripts為"otherpkgs",指定了要安裝的非操作系統(tǒng)光盤(pán)里的標(biāo)準(zhǔn)的rpm包，這也需要其他相關(guān)配置才行。
更改如下：
#chtab node=xcatdefaultspostscripts.postscripts="syslog,remoteshell,syncfiles,setupntp"
這里增加一個(gè)setupntp，指定所有的節(jié)點(diǎn)都要設(shè)置ntp時(shí)間同步。
#chtab node=compute??postscripts.postscripts="hardeths,configRSH,configService,configNFS"
這里自定義了compute這一段，他代表計(jì)算節(jié)點(diǎn)（必須要和nodelist表中g(shù)roups字段的定義一致），
定義了rpm包安裝后后執(zhí)行hardeths,configRSH,configService,configNFS幾個(gè)腳本。
這幾個(gè)腳本中hardeths為系統(tǒng)默認(rèn)就有，它指定節(jié)點(diǎn)設(shè)置固定IP地址，否則默認(rèn)是DHCP的。
其他腳本要自己寫(xiě)的, configRSH,configService,configNFS是自己寫(xiě)的腳本。
configRSH是節(jié)點(diǎn)在安裝時(shí)配置RSH無(wú)密碼。
configService是節(jié)點(diǎn)在安裝時(shí)配置需要起停的系統(tǒng)服務(wù)。
configNFS是節(jié)點(diǎn)在安裝時(shí)需要在/etc/fstab定義的NFS文件系統(tǒng),此次實(shí)施沒(méi)有配置
這些腳本的內(nèi)容請(qǐng)看附錄。
注意這些腳本要放在/install/postscripts目錄下，別忘了給他們加上可執(zhí)行屬性。
#chtab node=compute??postscripts.postbootscripts="setupGang,reboot"
定義了安裝完成后第一次啟動(dòng)執(zhí)行setupGang,reboot兩個(gè)腳本。
setupGang是配置節(jié)點(diǎn)安裝ganglia客戶(hù)端，腳本內(nèi)容參看附錄，此次實(shí)施沒(méi)有執(zhí)行
reboot就是重啟，默認(rèn)就有這個(gè)腳本。
再檢查一下：
#tabdump postscripts
#node,postscripts,postbootscripts,comments,disable
"xcatdefaults","configRSH,configService,setupntp,syslog,remoteshell,syncfiles","otherpkgs",,
"service","servicenode,xcatserver,xcatclient",,,
"compute","hardeths,configRSH,configService,setupntp","reboot",,
設(shè)置配置文件同步目錄
對(duì)于redhat系統(tǒng)來(lái)說(shuō)，創(chuàng)建一個(gè)/install/custom/install/rh目錄，這里放要安裝的額外rpm包和同步列表文件。
在本目錄寫(xiě)一個(gè)同步列表文件，這個(gè)文件的文件名是有規(guī)矩的，和nodetype表的定義有關(guān)，格式如下：
nodetype.profile+nodetype.os+nodetype.arch+synclist。
本例中，文件名為：compute.rhels5u5.x86_64.synclist，文件內(nèi)容如下：
/etc/hosts -> /etc/hosts
設(shè)置刀片中心
如果計(jì)算節(jié)點(diǎn)是刀片
1）給每個(gè)管理模塊配置IP地址
2）把這些AMM的IP加入管理節(jié)點(diǎn)的hosts文件
3）nodeadd把每個(gè)AMM加入xcat管理，使用和刀片計(jì)算節(jié)點(diǎn)不同的groups。
4）配置每個(gè)管理模塊的ssh和snmp
#rspconfig $管理模塊名字 snmpcfg=enable sshcfg=enable
rspconfig???BCE1?? snmpcfg=enable? sshcfg=enable
rspconfig???BCE2?? snmpcfg=enable? sshcfg=enable
rspconfig???BCE3?? snmpcfg=enable? sshcfg=enable
rspconfig???BCE4?? snmpcfg=enable? sshcfg=enable
rspconfig???BCE5? snmpcfg=enable? sshcfg=enable
rspconfig???BCE6? snmpcfg=enable? sshcfg=enable
rspconfig???BCE7?? snmpcfg=enable? sshcfg=enable
rspconfig???BCE8?? snmpcfg=enable? sshcfg=enable
rspconfig???BCE9?? snmpcfg=enable? sshcfg=enable
rspconfig???BCE10? snmpcfg=enable? sshcfg=enable
#rpower?管理模塊名字 reset
rpower??BCE1??? reset
在執(zhí)行rspconfig命令時(shí)，如果遇到Cannot communicate with XXXX的提示，需要用瀏覽器登到管理模塊，啟用SNMPv1
設(shè)置nodehm表

修改kickstar文件

#cp compute.rhels6.tmpl compute.rhels5u5.tmpl
#cp compute.rhels6.pkglistmycomp.rhels5u5.pkglist

其中.tmpl是kickstart文件，.pkglist是指定需要需要裝哪些軟件包
?
修改mycomp.rhels5u5.tmpl文件，
1)改分區(qū)劃分，注意rhel5不支持ext4

2)把cmdline注銷(xiāo)掉，這樣節(jié)點(diǎn)安裝時(shí)以傳統(tǒng)的網(wǎng)絡(luò)安裝字符界面進(jìn)行，比較順眼，這不是必須的。
修改compute.rhels5u5.pkglist
如果需要安裝所有的rpm包，這個(gè)文件只需要寫(xiě)兩行，如下：
[root@manager1 rh]# morecompute.rhels5u5.pkglist
kickstar_config/compute.rhels5u5.pkglist.201204174
@包名
注意：
1）在rhel5.5之后，不再支持everything這個(gè)詞了，rhel6也不行。
2）如果選擇安裝所有包，默認(rèn)節(jié)點(diǎn)會(huì)從虛擬化kernel啟動(dòng)。可以在postscripts里自己寫(xiě)一個(gè)腳本，讓系統(tǒng)從標(biāo)準(zhǔn)kernel啟動(dòng)。
?
復(fù)制安裝文件
cp *.iso?/install
copycds *.iso
mv rhels5.5? rhels5u5 (因?yàn)閚odetype定義的是rhels5u5; /install/rhels5u5 )
設(shè)置安裝
#rbootseq ON001-0N128??n,h,c,f??設(shè)置啟動(dòng)順序
#rbootseq ON001-0N128??stat
然后，啟動(dòng)計(jì)算節(jié)點(diǎn),從網(wǎng)絡(luò)啟動(dòng)即可。

rinstall ON001-ON126
