oracle root脚本,11g R2 运行root.sh脚本不成功的一个例子：

近日安装oracle 11g R2 集群时，在第1个节点运行root.sh脚本时没有成功。搞了一整天终于解决。记录一下：

1.---运行root.sh脚本

[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.

网上查找资料cannot restore segment prot after reloc: Permission denied

说是SELINUX 的原因，检查/etc/selinux/config 文件后，发现是有问题，想起来这个机器单独装过(选择文本方式的操作系统)，可能和之前其它节点的设置不同了。

[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

----这个文件也要检查。

[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
