**Oracle Study之--Oracle 11gR2构建RAC之hosts文件故障**

**系统环境：RedHat EL55**

**Oracle：    Oracle 11gR2 +GI**

在安装GI，运行root.sh script时，其中一个node出现以下错误：

**\[root@node2 ctssd\]\# /u01/11.2.0/grid/root.sh**

Running Oracle 11g root.sh script...
    The following environment variables are set as:
        ORACLE_OWNER= grid
        ORACLE_HOME=  /u01/11.2.0/grid
    Enter the full pathname of the local bin directory: [/usr/local/bin]: 
    The file "dbhome" already exists in /usr/local/bin.  Overwrite it? (y/n) 
    [n]: y
       Copying dbhome to /usr/local/bin ...
    The file "oraenv" already exists in /usr/local/bin.  Overwrite it? (y/n) 
    [n]: y
       Copying oraenv to /usr/local/bin ...
    The file "coraenv" already exists in /usr/local/bin.  Overwrite it? (y/n) 
    [n]: y

    Entries will be added to the /etc/oratab file as needed by
    Database Configuration Assistant when a database is created
    Finished running generic part of root.sh script.
    Now product-specific root actions will be performed.

\-----  启动ctssd 进程失败 ！

经检查发现，在node2的hosts文件出现以下错误：

**\[oracle@node2 ~\]$ 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 被解析成另一个node的主机名（node1）

**改为：**  
127.0.0.1        localhost.localdomain localhost

**重新运行root.sh脚本后成功！**

**\[root@node2 install\]\# crsctl check crs**
