xCAT安裝文檔
一、系統安裝規划( 實驗環境：Vmware Workstation )
| Master |
內網：10.1.1.11 eth0 custom |
|
| 外網：222.31.64.11 eth1 橋接 |
||
| Node01 |
10.1.1.12 |
注意：它們的網絡連接應該采用custom:Specific virtual network ; 還有一定要注意計算節點的mac地址是否正確 |
| Node02 |
10.1.1.13 |
一、禁用selinux
| [root@localhost ~]# 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 - 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 |
二、安裝xcat
1. 創建目錄並上傳文件
| [root@localhost ~]# mkdir -p /root/xcat2 [root@localhost ~]# cd /root/xcat2/ [root@localhost xcat2]# ll total 120800 -rw-r--r--. 1 root root 3496088 Apr 23 05:46 xcat-core-2.7.3.tar.bz2 -rw-r--r--. 1 root root 120193975 Apr 23 05:46 xcat-dep-201206121608.tar.bz2 [root@localhost xcat2]# |
2. 解壓縮文件
| [root@localhost xcat2]# tar -jvxf xcat-core-2.7.3.tar.bz2 [root@localhost xcat2]# tar -jxvf xcat-dep-201206121608.tar.bz2 [root@localhost xcat2]# ll total 120808 drwxrwxr-x. 3 root 1001 4096 Jun 18 2012 xcat-core -rw-r--r--. 1 root root 3496088 Apr 23 05:46 xcat-core-2.7.3.tar.bz2 drwxrwsrwx. 15 root root 4096 Jun 12 2012 xcat-dep -rw-r--r--. 1 root root 120193975 Apr 23 05:46 xcat-dep-201206121608.tar.bz2 [root@localhost xcat2]# |
3. 創建yum源
| [root@master cdrom]# mkdir -p /mnt/cdrom [root@master cdrom]# mkdir -p /mnt/iso [root@master cdrom]# mv /root/redhat6u2.iso /mnt/iso/ [root@master cdrom]# mount -o loop /mnt/iso/redhat6u2.iso /mnt/cdrom/ [root@master cdrom]# cd /etc/yum.repos.d/ [root@master cdrom]# mkdir bak [root@master cdrom]# mv rhel-source.repo bak/ [root@master cdrom]# touch myself.repo [root@master cdrom]# vi myself.repo
[houqd] name=RedHat baseurl=file:///mnt/cdrom enabled=1 gpgcheck=0 gpgkey=file:///mnt/cdrom/RPM-GPG-KEY-redhat-release
[root@master cdrom]# yum clean all Loaded plugins: product-id, refresh-packagekit, security, subscription-manager Updating certificate-based repositories. Cleaning repos: houqd Cleaning up Everything [root@master cdrom]# yum makecache Loaded plugins: product-id, refresh-packagekit, security, subscription-manager Updating certificate-based repositories. houqd | 4.0 kB 00:00 ... houqd/filelists_db | 3.6 MB 00:00 ... houqd/primary_db | 3.1 MB 00:00 ... houqd/other_db | 1.5 MB 00:00 ... houqd/group_gz | 195 kB 00:00 ... Metadata Cache Created [root@master cdrom]# |
4. 生成xcat的repo文件，並安裝
| [root@master xcat2]# [root@master xcat2]# cd xcat-core [root@master xcat-core]# ll total 3728 -rwxrwxr-x. 1 root 1001 222 Jun 22 2012 mklocalrepo.sh -rw-rw-r--. 1 root 1001 566780 Jun 18 2012 perl-xCAT-2.7.3-snap201206180512.noarch.rpm drwxrwxr-x. 2 root 1001 4096 Jun 18 2012 repodata -rw-rw-r--. 1 root 1001 255963 Jun 18 2012 xCAT-2.7.3-snap201206180516.i386.rpm -rw-rw-r--. 1 root 1001 255848 Jun 18 2012 xCAT-2.7.3-snap201206180516.ppc64.rpm -rw-rw-r--. 1 root 1001 255744 Jun 18 2012 xCAT-2.7.3-snap201206180516.s390x.rpm -rw-rw-r--. 1 root 1001 255944 Jun 18 2012 xCAT-2.7.3-snap201206180516.x86_64.rpm -rw-rw-r--. 1 root 1001 456805 Jun 18 2012 xCAT-client-2.7.3-snap201206180512.noarch.rpm -rw-rw-r--. 1 root 1001 224 Jun 22 2012 xCAT-core.repo -rw-rw-r--. 1 root 1001 50261 Jun 18 2012 xCAT-IBMhpc-2.7.3-snap201206180513.noarch.rpm -rw-rw-r--. 1 root 1001 20051 Jun 18 2012 xCAT-nbroot-core-ppc64-2.7.3-snap201206180516.noarch.rpm -rw-rw-r--. 1 root 1001 19913 Jun 18 2012 xCAT-nbroot-core-x86-2.7.3-snap201206180516.noarch.rpm -rw-rw-r--. 1 root 1001 20075 Jun 18 2012 xCAT-nbroot-core-x86_64-2.7.3-snap201206180516.noarch.rpm -rw-rw-r--. 1 root 1001 71040 Jun 18 2012 xCAT-rmc-2.7.3-snap201206180513.noarch.rpm -rw-rw-r--. 1 root 1001 1265491 Jun 18 2012 xCAT-server-2.7.3-snap201206180512.noarch.rpm -rw-rw-r--. 1 root 1001 11180 Jun 18 2012 xCATsn-2.7.3-snap201206180516.i386.rpm -rw-rw-r--. 1 root 1001 10852 Jun 18 2012 xCATsn-2.7.3-snap201206180516.ppc64.rpm -rw-rw-r--. 1 root 1001 10740 Jun 18 2012 xCATsn-2.7.3-snap201206180516.s390x.rpm -rw-rw-r--. 1 root 1001 11147 Jun 18 2012 xCATsn-2.7.3-snap201206180516.x86_64.rpm -rw-rw-r--. 1 root 1001 57360 Jun 18 2012 xCAT-test-2.7.3-snap201206180516.noarch.rpm -rw-rw-r--. 1 root 1001 179699 Jun 18 2012 xCAT-UI-2.7.3-snap201206180513.noarch.rpm [root@master xcat-core]# ./mklocalrepo.sh /root/xcat2/xcat-core [root@master xcat-core]# cd ../xcat-dep/rh6/x86_64/ [root@master x86_64]# ./mklocalrepo.sh /root/xcat2/xcat-dep/rh6/x86_64 [root@master x86_64]# # 檢查：此時會生成xcat的兩個repo文件 [root@master x86_64]# cd /etc/yum.repos.d/ [root@master yum.repos.d]# ll total 20 drwxr-xr-x 2 root root 4096 Apr 23 06:36 bak -rw-r--r-- 1 root root 119 Apr 23 06:37 myself.repo -rw-r--r-- 1 root root 78 Apr 23 06:37 redhat.repo -rw-r--r-- 1 root root 158 Apr 23 06:43 xCAT-core.repo -rw-r--r-- 1 root root 173 Apr 23 06:44 xCAT-dep.repo [root@master yum.repos.d]# [root@master yum.repos.d]# yum install xCAT Loaded plugins: product-id, refresh-packagekit, security, subscription-manager Updating certificate-based repositories. xcat-2-core | 951 B 00:00 ... xcat-2-core/primary | 7.3 kB 00:00 ... xcat-2-core 18/18 xcat-dep | 951 B 00:00 ... xcat-dep/primary | 15 kB 00:00 ... xcat-dep 33/33 Setting up Install Process Resolving Dependencies --> Running transaction check ---> Package xCAT.x86_64 0:2.7.3-snap201206180516 will be installed --> Processing Dependency: ipmitool-xcat >= 1.8.9 for package: xCAT-2.7.3-snap201206180516.x86_64 --> Processing Dependency: xCAT-server for package: xCAT-2.7.3-snap201206180516.x86_64 --> Processing Dependency: perl(xCAT::MsgUtils) for package: xCAT-2.7.3-snap201206180516.x86_64 --> Processing Dependency: xCAT-client for package: xCAT-2.7.3-snap201206180516.x86_64 --> Processing Dependency: xCAT-genesis-x86_64 for package: xCAT-2.7.3-snap201206180516.x86_64 --> Processing Dependency: /bin/ksh for package: xCAT-2.7.3-snap201206180516.x86_64 --> Processing Dependency: perl-Net-Telnet for package: xCAT-2.7.3-snap201206180516.x86_64 --> Processing Dependency: perl(xCAT::Utils) for package: xCAT-2.7.3-snap201206180516.x86_64 tcl.x86_64 1:8.5.7-6.el6 tftp-server.x86_64 0:0.49-7.el6 vsftpd.x86_64 0:2.2.2-6.el6_0.1 xCAT-client.noarch 4:2.7.3-snap201206180512 xCAT-genesis-x86_64.noarch 1:2.7.3-snap201206111431 xCAT-server.noarch 4:2.7.3-snap201206180512 xinetd.x86_64 2:2.3.14-33.el6 xnba-undi.noarch 0:1.0.3-7 yaboot-xcat.noarch 0:1.3.17-rc1

5. 檢查xCAT是否安裝正確
| [root@master xcat2]# source /etc/profile.d/xcat.sh [root@master xcat2]# tabdump site #key,value,comments,disable "blademaxp","64",, "fsptimeout","0",, "installdir","/install",, "ipmimaxp","64",, "ipmiretries","3",, "ipmitimeout","2",, "consoleondemand","no",, "master","10.1.1.11",, # 應該為master的ip "nameservers","10.1.1.11",, # 應該為master的ip "maxssh","8",, "ppcmaxp","64",, "ppcretry","3",, "ppctimeout","0",, "powerinterval","0",, "syspowerinterval","0",, "sharedtftp","1",, "SNsyncfiledir","/var/xcat/syncfiles",, "tftpdir","/tftpboot",, "xcatdport","3001",, "xcatiport","3002",, "xcatconfdir","/etc/xcat",, "timezone","America/Los_Angeles",, "useNmapfromMN","no",, "enableASMI","no",, "db2installloc","/mntdb2",, "databaseloc","/var/lib",, "sshbetweennodes","ALLGROUPS",, "dnshandler","ddns",, "vsftp","n",, "cleanupxcatpost","no",, "dhcplease","43200",, [root@master xcat2]# |
6. 配置xcat的相關服務(集群服務包括：network服務、NTP服務、DNS服務、集群管理服務)
| # 配置networks表 [root@master ~]# tabdump networks #netname,net,mask,mgtifname,gateway,dhcpserver,tftpserver,nameservers,ntpservers,logservers,dynamicrange,nodehostname,ddnsdomain,vlanid,domain,comments,disable "10_1_1_0-255_255_255_0","10.1.1.0","255.255.255.0","eth0","10.1.1.11","10.1.1.11","10.1.1.11",,"10.1.1.11","10.1.1.11",,,,,,, # 注：直接用tabedit networks修改 # 配置NTP(網絡時間同步) [root@master ~]# [root@master ~]# mv /etc/ntp.conf /etc/ntp.conf.bak [root@master ~]# vi /etc/ntp.conf server 10.1.1.11 # Local clock fudge 10.1.1.11 stratum 10 driftfile /var/lib/ntp/drift
[root@master ~]# chkconfig --level 345 ntpd on [root@master ~]# chkconfig --list | grep ntpd ntpd 0:off 1:off 2:off 3:on 4:on 5:on 6:off ntpdate 0:off 1:off 2:off 3:off 4:off 5:off 6:off [root@master ~]# service ntpd restart Shutting down ntpd: [FAILED] Starting ntpd: [ OK ]
我們需要將ntp服務器記錄到site表里： [root@master ~]# chtab key=ntpservers site.value=10.1.1.11 [root@master ~]# tabdump site #key,value,comments,disable "blademaxp","64",, "fsptimeout","0",, "installdir","/install",, "ipmimaxp","64",, "ipmiretries","3",, "ipmitimeout","2",, "consoleondemand","no",, "master","10.1.1.11",, "nameservers","10.1.1.11",, "maxssh","8",, "ppcmaxp","64",, "ppcretry","3",, "ppctimeout","0",, "powerinterval","0",, "syspowerinterval","0",, "sharedtftp","1",, "SNsyncfiledir","/var/xcat/syncfiles",, "tftpdir","/tftpboot",, "xcatdport","3001",, "xcatiport","3002",, "xcatconfdir","/etc/xcat",, "timezone","America/Los_Angeles",, "useNmapfromMN","no",, "enableASMI","no",, "db2installloc","/mntdb2",, "databaseloc","/var/lib",, "sshbetweennodes","ALLGROUPS",, "dnshandler","ddns",, "vsftp","n",, "cleanupxcatpost","no",, "dhcplease","43200",, "ntpservers","10.1.1.11",, # 此時查看會多出一行來 如果希望xcat安裝的節點也自動設置好NTP服務，需要在postscripts表中加入setupntp的腳本: [root@master ~]# tabdump postscripts #node,postscripts,postbootscripts,comments,disable "xcatdefaults","syslog,remoteshell,syncfiles","otherpkgs",, "service","servicenode",,, [root@master ~]# chtab node=xcatdefaults postscripts.postscripts=syslog,remoteshell,setupntp [root@master ~]# tabdump postscripts #node,postscripts,postbootscripts,comments,disable "xcatdefaults","syslog,remoteshell,setupntp","otherpkgs",, "service","servicenode",,, [root@master ~]#
# 設置DNS 如果系統中安裝了bind-chroot的軟件包，會與想xCAT沖突，所以如果安裝了bind-chroot需要把它卸載掉： [root@master ~]# rpm -qa | grep bind-chroot [root@master ~]# [root@master ~]# rpm -e bind-chroot
在site表中定義DNS服務器Ip地址為10.1.1.11，域名為cluster.com
[root@master ~]# chtab key=domain site.value=cluster.com 配置DNS解析，編輯/etc/hosts，把集群中所有節點都加進去： [root@master ~]# vi /etc/hosts
127.0.0.1 localhost localhost.localdomain localhost4 localhost4.localdomain4 ::1 localhost localhost.localdomain localhost6 localhost6.localdomain6 10.1.1.11 master 10.1.1.12 node01 10.1.1.13 node02
執行DNS配置生成命令： [root@master ~]# makedns -n Handling localhost in /etc/hosts. Handling localhost in /etc/hosts. Handling master in /etc/hosts. Handling node01 in /etc/hosts. Handling node02 in /etc/hosts. Getting reverse zones, this may take several minutes in scaling cluster. Completed getting reverse zones. Updating zones. Completed updating zones. Starting named complete Restarting named Restarting named complete Updating DNS records, this may take several minutes in scaling cluster. Completed updating DNS records. named has been enabled on boot. DNS setup is completed
配置/etc/resolv.conf，把nameserver指向管理服務器自己 [root@master ~]# vi /etc/resolv.conf search cluster.com nameserver 10.1.1.11 啟動DNS服務，並設置開機自啟動 [root@master ~]# service named restart Stopping named: . [ OK ] Starting named: [ OK ] [root@master ~]# chkconfig --level 345 named on [root@master ~]# chkconfig --list | grep named named 0:off 1:off 2:on 3:on 4:on 5:on 6:off [root@master ~]# 運行nslookup node01來檢查能否正常解析： [root@master ~]# nslookup node01 Server: 10.1.1.11 Address: 10.1.1.11#53
Name: node01.cluster.com Address: 10.1.1.12
