11g RacR2 修改主机HOSTNAME详解
1. Hosts文件配置
两个节点xulq1和xulq2，/etc/hosts的配置如下
#public ip
192.168.56.80 xulq1
192.168.56.81 xulq2
#priv ip
192.168.100.10 xulq1-priv
192.168.100.11 xulq2-priv
#vip ip
192.168.56.82 xulq1-vip
192.168.56.83 xulq2-vip
#scan ip
192.168.56.84 xulq-scan
2. CRS集群状态
[grid@xulq2 ~]$ crsctl stat res -t

现在要把两个节点的主机名改为: xurac1和 xurac2
3. 卸载CRS,在非最后一个节点运行

5. 修改主机名称
smitty tcpip修改主机名
第一节点：xulq1 修改为 xurac1
第一节点：xulq2 修改为 xurac2
修改方法:
hostname xurac1
hostname xurac2
vi /etc/sysconfig/network
vi /etc/hosts
：g/xulq1/s//xurac1/g
：g/xulq2/s//xurac2/g
6. 修改11g grid的参数文件(Node1,Node2)
$vi ORACLE_HOME/crs/install/crsconfig_params
：g/xulq1/s//xurac1/g
：g/xulq2/s//xurac2/g
7. 重建grid用户互信
因为主机名修改了，两节点间grid用户信任关系需要重建
$/u01/product/11.2/grid/deinstall/sshUserSetup.sh-user grid -hosts xurac1 xurac2 -noPromptPassphrase
8. 在各个节点依次运行root.sh脚本
节点1运行root.sh
另外一个节点运行root.sh
# /u01/product/11.2/grid/root.sh
[root@xurac1 ~]#/u01/product/11.2/grid/root.sh
