redhat el5 安裝oracle 10g rac之--crs 安裝
系統環境：
作業系統：redhat el5
cluster： oracle crs 10.2.0.1.0
oracle： oracle 10.2.0.1.0
如圖所示：rac 系統架構
二、crs 安裝
cluster ready service是oracle 建構rac,負責叢集資源管理的軟體，在搭建rac中必須首先安裝.
安裝需采用圖形化方式，以oracle使用者的身份安裝(在node1上）：
注意：修改安裝配置檔案，增加redhat-5的支援
[oracle@node1 install]$ pwd
/home/oracle/cluster/install
[oracle@node1 install]$ ls
addlangs.sh images oneclick.properties oraparamsilent.ini response
addnode.sh lsnodes oraparam.ini resource unzip
[oracle@node1 install]$ vi oraparam.ini
[certified versions]
linux=redhat-3,suse-9,redhat-4,redhat-5,unitedlinux-1.0,asianux-1,asianux-2
[oracle@node1 cluster]$./runinstaller
歡迎界面
注意安裝crs的主目錄，不能和oracle軟體的目錄一緻，需單獨在另一個目錄
[oracle@node1 ~]$ ls -l /u01
total 24
drwxr-xr-x 3 oracle oinstall 4096 may 5 17:04 app
drwxr-xr-x 36 oracle oinstall 4096 may 7 11:08 crs_1
drwx------ 2 oracle oinstall 16384 may 4 15:59 lost+found
[oracle@node1 ~]$
添加節點（如果主機間信任關系配置有問題，這裡就無法發現node 2）
修改public 網卡屬性（public 網卡用于和client 通訊）
ocr必須采用raw裝置（exteneral redundancy隻需一個raw,安裝後可以添加mirror)
vote disk必須采用raw裝置（exteneral redundancy隻需一個raw,安裝後可以添加多個raw構成備援)
開始安裝（并将安裝軟體傳送到node2）
安裝提示分别在兩個節點按順序執行script
node1：
[root@node1 ~]# /u01/app/oracle/orainventory/orainstroot.sh
changing permissions of /u01/app/oracle/orainventory to 770.
changing groupname of /u01/app/oracle/orainventory to oinstall.

node2：

出現以上錯誤，解決方法：
[root@node2 bin]# vi vipca
linux) ld_library_path=$oracle_home/lib:$oracle_home/srvm/lib:$ld_library_path
export ld_library_path
#remove this workaround when the bug 3937317 is fixed
arch=`uname -m`
if [ "$arch" = "i686" -o "$arch" = "ia64" ]
then
ld_assume_kernel=2.4.19
export ld_assume_kernel
fi
unset ld_assume_kernel （添加此行資訊）
#end workaround
[root@node2 bin]# vi srvctl
ld_assume_kernel=2.4.19
export ld_assume_kernel
unset ld_assume_kernel（添加此行資訊）
在node 2重新執行root.sh：
注意：root.sh隻能執行一次，如果再次執行，需執行rootdelete.sh
[root@node2 bin]# /u01/crs_1/root.sh
oracle crs stack is already configured and will be running under init(1m)
[root@node2 bin]# cd ../install
[root@node2 install]# ls
cluster.ini install.incl rootaddnode.sbs rootdelete.sh templocal
cmdllroot.sh make.log rootconfig rootinstall
envvars.properties paramfile.crs rootdeinstall.sh rootlocaladd
install.excl preupdate.sh rootdeletenode.sh rootupgrade
[root@node2 install]# ./rootdelete.sh

[root@node2 install]#
node 2 再次出錯：
[root@node2 install]# /u01/crs_1/root.sh
error 0(native: listnetinterfaces:[3])
[error 0(native: listnetinterfaces:[3])]
解決方法：（配置網絡）
[root@node2 bin]# ./oifcfg iflist
eth0 192.168.8.0
eth1 10.10.10.0
[root@node2 bin]# ./oifcfg getif
[root@node2 bin]# ./oifcfg setif -global eth0/192.168.8.0:public
[root@node2 bin]# ./oifcfg setif -global eth1/10.10.10.0:cluster_interconnect
eth0 192.168.8.0 global public
eth1 10.10.10.0 global cluster_interconnect
并在node2上執行vipca:
以root身份執行vipca（在/u01/crs_1/bin)
配置資訊應和/etc/hosts檔案一緻
開始配置
vipca配置成功後，crs服務正常工作
安裝完成！
驗證crs:
[root@node2 bin]# crs_stat -t
name type target state host
------------------------------------------------------------
ora.node1.gsd application online online node1
ora.node1.ons application online online node1
ora.node1.vip application online online node1
ora.node2.gsd application online online node2
ora.node2.ons application online online node2
ora.node2.vip application online online node2
[root@node1 ~]# crs_stat -t
附：錯誤案例
如果在運作root.sh時出現以下錯誤：
在出現錯誤的節點上運作（root）vipca 解決！
@至此crs安裝成功！
