近日安裝oracle 11g R2 叢集時，在第1個節點執行root.sh指令碼時沒有成功。搞了一整天終於解決。記錄一下：
1.---執行root.sh指令碼
[root@lir-rac1 install]# /u01/app/11.2.0.0/grid/root.sh
Running Oracle 11g root.sh script...
The following environment variables are set as:
    ORACLE_OWNER= grid
    ORACLE_HOME= /u01/app/11.2.0.0/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
   Copying coraenv to /usr/local/bin ...
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.

2.-----------------------------------------------------
網上查詢資料cannot restore segment prot after reloc: Permission denied
說是SELINUX 的原因，檢查/etc/selinux/config 檔案後，發現是有問題，想起來這個機器單獨裝過（選擇文字方式的作業系統），可能和之前其它節點的設定不同了。

[root@lir-rac1 install]# vi /etc/selinux/config
# This file controls the state of SELinux on the system.
# SELINUX= can take one of these three values:
#       enforcing - SELinux security policy is enforced.
#       permissive - SELinux prints warnings instead of enforcing.
#       disabled - SELinux is fully disabled.
#SELINUX=enforcing
SELINUX=disabled
# SELINUXTYPE= type of policy in use. Possible values are:
#       targeted - Only targeted network daemons are protected.
#       strict - Full SELinux protection.
SELINUXTYPE=targeted
----這個檔案也要檢查。
[root@lir-rac1 install]# vi /etc/sysconfig/selinux
# This file controls the state of SELinux on the system.
# SELINUX= can take one of these three values:
#       enforcing - SELinux security policy is enforced.
#       permissive - SELinux prints warnings instead of enforcing.
#       disabled - SELinux is fully disabled.
#SELINUX=enforcing
SELINUX=disabled
# SELINUXTYPE= type of policy in use. Possible values are:
#       targeted - Only targeted network daemons are protected.
#       strict - Full SELinux protection.
SELINUXTYPE=targeted

---再次執行root.sh指令碼，還是提示錯誤。仔細看提示資訊。

使用chcon命令改變檔案的SELinux屬性：
[root@lir-rac1 install]# chcon -t texrel_shlib_t /u01/app/11.2.0.0/grid/lib/libclntsh.so.11.1
