每个节点服务器必须是 双网卡 ，支持tcp/ip协议，安装集群软件服务器要支持udp
防火墙关闭
service iptables stop
SELinux禁用
vi /etc/selinux/config
SELINUX=disable
ip地址使用静态配置：static
网关要指定
# Intel Corporation 82566MM Gigabit Network Connection
DEVICE=eth0
BOOTPROTO=static
IPADDR=10.1.1.135
NETMASK=255.255.255.0
GATEWAY=10.1.3.1
HWADDR=00:1E:37:D6:FA:44
ONBOOT=yes
重启network :service network restart
hostname不要出现在回环地址！
如果启动过单机asm服务，请先停止:$ORACLE_HOME/bin/localconfig delete
卸载独占模式的oracle软件（先用OUI卸载，再手工清理垃圾文件/etc/*.ora $ORACLE_HOME）
如果是4以上的版本，降低版本到4
/etc/redhat-release

配置hangcheck-timer:用于监视 Linux 内核是否挂起
vi /etc/modprobe.conf
options hangcheck-timer hangcheck_tick=30 hangcheck_margin=180
自动加载hangcheck-timer
vi /etc/rc.local
modprobe hangcheck-timer

安装clusterware软件(只需在一个节点做，但要手工将其它节点加入到群):
/mnt/clusterware/runInstaller
在运行/u01/crs_1/root.sh脚本之前,在所有节点修改vipca & srvctl
su - oracle
cd $CRS_HOME/bin
vi +123 vipca
vi + srvctl
~~~~~~~~~~~~~~~~
unset LD_ASSUME_KERNEL
/u01/crs_1/root.sh
如果报错:
Running vipca(silent) for configuring nodeapps
Error 0(Native: listNetInterfaces:[3])
[Error 0(Native: listNetInterfaces:[3])]
解决(只需在一个节点做):
cd /u01/crs_1/bin
#./oifcfg iflist
#./oifcfg setif -global eth0/10.1.1.0:public
#./oifcfg setif -global eth0:0/10.1.2.0:cluster_interconnect
#./oifcfg getif
手工运行vipca，完成root.sh脚本!
校验集群后台进程的状态:
cd /u01/crs_1/bin
[oracle@xie bin]$ ./crs_stat -t

在root下备份OCR:
cd /u01/crs_1/bin
./ocrconfig -export /home/oracle/bk/ocr/ocr1.bk
------------------------------------------------------------------------------------------
安装数据库软件(只需在一个节点做，会出现多节点的选择选项):安装时选择只安装软件不建库
/mnt/database/runInstaller
配置集群的数据库网络:
netca
－－－－－－－－－－－－－－－－－－－－－－－－－－－－－－－－－－－－－－－－－－－－－－－－－－－－－－－－
打补丁:
1.在所有节点用root用户停集群
[root@xie bin]# /etc/init.d/init.crs stop
[oracle@xie bin]$ ./crs_stat -t
CRS-0184: Cannot communicate with the CRS daemon.
2.运行./runInstaller打补丁
1. 先为clusterware 打补丁 ，运行./runInstaller 选择（完成之后根据提示运行2个脚本）
打完补丁后，会自动启动集群服务
[oracle@xie1 bin]$ ./crs_stat -t

ora....E1.lsnr application ONLINE ONLINE xie1
ora.xie1.gsd application ONLINE ONLINE xie1
ora.xie1.ons application ONLINE ONLINE xie1
ora.xie1.vip application ONLINE ONLINE xie1
2. 然后再为库打补丁，运行./runInstaller 选择
[root@xie bin]# /etc/init.d/init.crs stop
[oracle@xie bin]$ ./crs_stat -t
CRS-0184: Cannot communicate with the CRS daemon.
这里装完之后不会自动起集群服务
－－－－－－－－－－－－－－－－－－－－－－－－－－－－－－－－－－－－－－－－－－－－－－－－－－－－
安装数据库：
用dbca建库（在一台节点建库）
建好之后查询集群状态：
[oracle@xie bin]$ ./crs_stat -t
