xcat 安装（liunx高性能刀片集群管理软件）
xcat 安装（liunx高性能刀片集群管理软件）
目录(?)[+]
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

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

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 �Cn
#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
