xcat 安装（liunx高性能刀片集群管理软件）

xcat非常方便，hp有cmu，当然那个是花钱的，xcat是ibm前两年开源的一个软件，功能可以说还是够强大的。

1、先删除掉冲突软件

xCAT2和操作系统的载OpenIPMI-tools和tftpserver不兼容，需要把这两个包删除。

同时bind-chroot和dhcp-chroot软件包如果存在也会导致问题，需要删除。

# rpm -e --nodeps  tftp-server-0.49-2

2、xCAT2软件安装

创建xcat的yum安装源

把xcat上传到服务器，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）创建xcat-core的yum安装源

# cd xcat-core

#./mklocalrepo.sh

2)创建xcat-dep的yum安装源

#cd ../xcat-dep/rh5/x86_64

#./mklocalrepo.sh

 

安装xCAT

# yum install xCAT

根据提示进行安装即可.

默认安装到/opt/xcat目录中

测试

#source /etc/profile.d/xcat.sh

#tabdump 将列出xcat所有可配置的表。读取site表

设置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

"172_16_1_0-255_255_255_0","172.16.1.0","255.255.255.0","eth1","172.16.1.253","172.30.1.129","172.16.1.1","172.16.1.1","172.16.1.1",,,,,,,

按环境改

# 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

使用这类命令来设置，建议

netname,net,mask,mgtifname,dhcpserver,tftpserver,nameservers,ntpservers,logservers这些都设置上。

注意：

当不设置dynamicrange这个字段时，系统可以按照mac地址一对一的分配IP地址。不过在makedhcp时会有一条告警，不用管它。（建议方式）

设置dynamicrange这个字段时，系统不能按照mac地址一对一的分配IP地址。（在集群连接用户现有网络时，可能会产生灾难性的后果

设置passwd密码表

#chtab key=systempasswd.username=root passwd.password=root123（用于每个xcat安装出来的节点）

#chtab key=bladepasswd.username=USERID passwd.password=PASSW0RD（对应刀箱的AMM管理模块）

#chtab key=ipmipasswd.username=USERID passwd.password=PASSW0RD（对应机架式服务器的IMM管理模块）

[root@manager1 yum.repos.d]#tabdump passwd  查看password表

#key,username,password,cryptmethod,comments,disable

"system","root","root123",,,

"blade","USERID","PASSW0RD",,,

设置nodelist表

#nodeadd ON001-ON128 groups=all,compute

#nodeadd L001-L002 groups=all,compute

#nodeadd manager1-manager2  groups=all,compute

[root@serv ~]# tabdump nodelist  检查nodelist表

设置noderes表

servicenode,tftpserver,nfsserver,monserver,installnic,primarynic,xcatmaster

discoverynics可根据具体环境，不是必须。建议配置以上服务

设置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=节点名nodetype.os=rhels5u5 nodetype.arch=x86_64 nodetype.profile=compute nodetype.nodetype=osi

在nodetype表中，定义计算节点ON001-ON126的操作系统是rhels5.5

x86_64，使用的profile是compute，节点类型是osi(OS image)

注意这里的nodetype.os、nodetype.profile这两个字段和kickstart文件名关联，如上设置，则：

kickstart文件名为：compute.rhels5u5.tmpl

kickstart软件包列表的文件名为：compute.rhels5u5.pkglist

compute.tmpl+compute.pkglist 存放位置

/opt/xcat/share/xcat/install/rh

设置postscripts表

这个表指定在kickstart安装前，rpm包安装后和安装完成后第一次启动时执行的脚本，不同集群的环境定制全都在这里做。

[root@manager1 etc]# tabdumppostscripts

#node,postscripts,postbootscripts,comments,disable

"xcatdefaults","syslog,remoteshell,syncfiles,setupntp","otherpkgs",,

"service","servicenode,xcatserver,xcatclient",,,

"compute","hardeths,configRSH,configService",,,

postscripts这列表示rpm包安装后后执行。

postbootscripts这列表示安装完成后第一次启动时执行的脚本。

其中,xcatdefaults和service这两段为系统默认就有

xcatdefaults这个段代表所有节点都要执行的脚本

service是服务节点需要执行的脚本，服务节点是在较大（也许256节点以上）的集群环境中配置的，主要是分担管理节点的压力。

所有脚本位于/install/postscripts目录下

xcatdefaults默认的postscripts为"syslog,remoteshell,syncfiles"。

1）syslog脚本把各节点的log重定向到管理节点。

2）remoteshell脚本设置ssh无密码互通。注意xcat默认情况下root从管理节点ssh到各被管节点ssh无密码，但是从被管节点ssh到管理节点是要密码的。

3）syncfiles脚本指定安装过程中要同步的文件。但还需要其他相关配置，详细后面说明。

xcatdefaults默认的postscripts为"otherpkgs",指定了要安装的非操作系统光盘里的标准的rpm包，这也需要其他相关配置才行。

更改如下：

#chtab node=xcatdefaultspostscripts.postscripts="syslog,remoteshell,syncfiles,setupntp"

这里增加一个setupntp，指定所有的节点都要设置ntp时间同步。

#chtab node=compute  postscripts.postscripts="hardeths,configRSH,configService,configNFS"

这里自定义了compute这一段，他代表计算节点（必须要和nodelist表中groups字段的定义一致），

定义了rpm包安装后后执行hardeths,configRSH,configService,configNFS几个脚本。

这几个脚本中hardeths为系统默认就有，它指定节点设置固定IP地址，否则默认是DHCP的。

其他脚本要自己写的, configRSH,configService,configNFS是自己写的脚本。

configRSH是节点在安装时配置RSH无密码。

configService是节点在安装时配置需要起停的系统服务。

configNFS是节点在安装时需要在/etc/fstab定义的NFS文件系统,此次实施没有配置

这些脚本的内容请看附录。

注意这些脚本要放在/install/postscripts目录下，别忘了给他们加上可执行属性。

#chtab node=compute  postscripts.postbootscripts="setupGang,reboot"

定义了安装完成后第一次启动执行setupGang,reboot两个脚本。

setupGang是配置节点安装ganglia客户端，脚本内容参看附录，此次实施没有执行

reboot就是重启，默认就有这个脚本。

再检查一下：

#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",,

设置配置文件同步目录

对于redhat系统来说，创建一个/install/custom/install/rh目录，这里放要安装的额外rpm包和同步列表文件。

在本目录写一个同步列表文件，这个文件的文件名是有规矩的，和nodetype表的定义有关，格式如下：

nodetype.profile+nodetype.os+nodetype.arch+synclist。

本例中，文件名为：compute.rhels5u5.x86_64.synclist，文件内容如下：

/etc/hosts -> /etc/hosts

设置刀片中心

如果计算节点是刀片

1）给每个管理模块配置IP地址

2）把这些AMM的IP加入管理节点的hosts文件

3）nodeadd把每个AMM加入xcat管理，使用和刀片计算节点不同的groups。

4）配置每个管理模块的ssh和snmp

#rspconfig $管理模块名字 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 管理模块名字 reset

rpower  BCE1    reset

在执行rspconfig命令时，如果遇到Cannot communicate with XXXX的提示，需要用浏览器登到管理模块，启用SNMPv1

设置nodehm表

#chtab node=ON001  nodehm.mgt=blade

[root@manager1 postscripts]#tabdump nodehm  查看nodehm表

设置dns

#makedns –n

#makedns compute

#chkconfig named on

测试一下

#nslookup

注意：

管理节点的DNS服务一定要正常，否则白搭。

设置dhcp

#makedhcp -n

#makedhcp compute 或者makedhcp all

如果只设置某个节点，可以如下：

#makedhcp node01

修改kickstar文件

进入/opt/xcat/share/xcat/install/rh

#cp compute.rhels6.tmpl compute.rhels5u5.tmpl

#cp compute.rhels6.pkglistmycomp.rhels5u5.pkglist

(针对jss服务器为jss.rhel5u5.tmpl; jss.rhel5u5.pkglist.针对oracle服务器为oracle.rhel5u5.tmpl; oracle.rhel5u5.pkglist.)

其中.tmpl是kickstart文件，.pkglist是指定需要需要装哪些软件包

 

修改mycomp.rhels5u5.tmpl文件，

1)改分区划分，注意rhel5不支持ext4

[root@manager1 rh]# morecompute.rhels5u5.tmpl

2)把cmdline注销掉，这样节点安装时以传统的网络安装字符界面进行，比较顺眼，这不是必须的。

修改compute.rhels5u5.pkglist

如果需要安装所有的rpm包，这个文件只需要写两行，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这个词了，rhel6也不行。

2）如果选择安装所有包，默认节点会从虚拟化kernel启动。可以在postscripts里自己写一个脚本，让系统从标准kernel启动。

 

复制安装文件

cp *.iso /install

copycds *.iso

mv rhels5.5  rhels5u5 (因为nodetype定义的是rhels5u5; /install/rhels5u5 )

设置安装

#rbootseq ON001-0N128  n,h,c,f  设置启动顺序

#rbootseq ON001-0N128  stat

然后，启动计算节点,从网络启动即可。

rpower compute  off

rinstall ON001-ON126

nodestat  ON001-ON126 (查看各节点状态)

补充：

configRSH脚本

#!/bin/sh

#

    chkconfig $i on;

    echo $i >> /etc/securetty;

done;
