Oracle Study之--Oracle 11gR2構建RAC之hosts文件故障
系統環境:RedHat EL55
Oracle: Oracle 11gR2 +GI
在安裝GI,運行root.sh script時,其中一個node出現以下錯誤:
[root@node2 ctssd]# /u01/11.2.0/grid/root.sh

----- 啟動ctssd 進程失敗 !
經檢查發現,在node2的hosts文件出現以下錯誤:
[oracle@node2 ~]$ cat /etc/hosts
# Do not remove the following line, or various programs
# that require network functionality will fail.
127.0.0.1 node1 localhost.localdomain localhost
::1 localhost6.localdomain6 localhost6
192.168.3.101 node1
192.168.3.111 node1-vip
10.10.10.1 node1-priv
192.168.3.102 node2
192.168.3.112 node2-vip
10.10.10.2 node2-priv
192.168.3.12 rac-scan
------- 127.0.0.1 被解析成另一個node的主機名(node1)
改為:
127.0.0.1 localhost.localdomain localhost
重新運行root.sh腳本后成功!
