如果是rac的某个节点的误操作，那么还可以通过delete node然后add node来做，不过这个相对麻烦太多了，但是或许是最保险的一种方式。oracle也推荐这样，因为你如果人为修改文件权限，很难保证以后运行过程中不会出现什么问题。

1.1 权限修复

1.1.1      如果 $GRID_HOME 下的权限被人为修改过，那么如何来修复该权限问题？

参考连接： http://blog.itpub.net/26736162/viewspace-2121470/

 

使用chown -R误操作将整个$GRID_BASE或$GRID_HOME的权限修改了，或者删除了 $GRID_HOME/log 文件夹下的所有内容，导致集群不能启动。在这种情况下可以根据 MOS 文档： Tips for checking file permissions on GRID environment(ID 1931142.1) 来修复该问题。

该文档中描述到，在 $GRID_HOME/crs/utl （ Oracle 11.2 及 12.1.0.1 ）或 /crs/utl/ （ Oracle 12.1.0.2 ）下面的crsconfig_dirs和crsconfig_fileperms文件中记录了整个 $GRID_HOME 下面的文件和目录的相关权限。

Check the permissions from the following 2 files which are created during Grid Infrastructure installation.

In $GRID_HOME/crs/utl (for 11.2 and 12.1.0.1) and /crs/utl/ (for 12.1.0.2) directory:

crsconfig_dirs ： which has all directories listed in and their permissions

crsconfig_fileperms ： which has list of files and their permissions and locations in .

 

[root@raclhr-11gR2-N1 utl]# ll $ORACLE_HOME/crs/utl/crsconfig_*

-rw-r--r-- 1 root root  8554 May 17 13:31 /u01/app/11.2.0/grid/crs/utl/crsconfig_dirs

-rw-r--r-- 1 root root 12619 May 17 13:31 /u01/app/11.2.0/grid/crs/utl/crsconfig_fileperms

-rw-r--r-- 1 root root 11218 May 17 13:31 /u01/app/11.2.0/grid/crs/utl/crsconfig_files

误操作：

chown -R oracle.oinstall $ORACLE_HOME

ps -ef |grep d.bin|grep -v grep|awk '{print $2}' | xargs kill -9

 

可以通过命令“cluvfy comp software -n all -verbose”来校验集群的权限是否正确。

 

所以要解决这个问题其实并不难，大致可以通过如下几种方法来解决：

1 、根据 MOS 文档 1931142.1 提供的建议通过 $GRID_HOME/crs/install/rootcrs.pl -init 或 roothas.pl -init 进行解决。该方法可以用来解决删除了 $GRID_HOME/log 文件夹下的所有内容，导致集群不能启动的情况，但是对于chown -R误操作将整个$GRID_HOME的权限修改了的情况不一定能恢复。

For 11.2:

For clustered Grid Infrastructure, as root user

# cd /crs/install/

# ./rootcrs.pl -init

For Standalone Grid Infrastructure, as root user

# cd /crs/install/

# ./roothas.pl  -init

For 12c:

For clustered Grid Infrastructure, as root user

# cd /crs/install/

# ./rootcrs.sh -init

For Standalone Grid Infrastructure, as root user

# cd /crs/install/

# ./roothas.sh -init

rootcrs.pl – init 是在 PSU>11.2.0.3.6 下执行的，如果 PSU<11.2.0.3.6 可以执行如下两条命令来实现同样的效果。

/crs/install/rootcrs.pl -unlock

/crs/install/rootcrs.pl -patch

 

2、 采用 MOS 文档 1515018.1 上提供的脚本 permission.pl 在权限正常节点上生成修复脚本，然后将生成的修复脚本在异常节点上执行来修复权限问题。可以用来修复chown -R误操作将整个$GRID_HOME的权限修改了的情况。

注意，该脚本会产生 2 个文件：

a. permission- - This contains file permission in octal value, owner and group information of the files captured

b. restore-perm-.cmd - This contains command to change the permission, owner, and group of the captured files

修复时只需要执行 restore-perm-.cmd 文件即可。在执行脚本之前，需要将脚本中的节点名称替换成异常节点名。 vi 下的替换命令为：

:%s/raclhr-11gr2-n2/raclhr-11gr2-n1/g     替换每一行中所有 raclhr-11gr2-n2 为 raclhr-11gr2-n1

 

3 、 Oracle 11gR2 可以 deconfig crs 的配置，然后重新运行 root.sh 即可。如果 OCR 和数据库不再同一个磁盘组里，那么重新运行 root.sh 脚本并不影响数据库，所以无需担心。可以用来修复 OCR 、 OLR 或表决磁盘损坏的情况，或 ASM 节点号和主机节点号不一致的情况。

$GRID_HOME/crs/install/rootcrs.pl -deconfig -force -verbose

dd if=/dev/zero of=/dev/rhdiskN bs=1024k count=1024  -- 清理磁盘头

$GRID_HOME/root.sh

在 root.sh 脚本执行完毕后，需要再次将数据库、监听和 SERVICE 等其它资源添加进集群中：

srvctl add db -d lhrrac1 -r PRIMARY -o $ORACLE_HOME

srvctl add instance -d lhrrac1 -i lhrrac11 -n raclhr-11gR2-N1

srvctl add instance -d lhrrac1 -i lhrrac12 -n raclhr-11gR2-N2

srvctl add listener -l LISTENER -o $ORACLE_HOME

 

1.1.2      $ORACLE_HOME/bin/oracle 文件的权限修复

在安装有 GI 的环境下，权限、属主是严格被设定的，任何对于它们的错误修改容易引发一系列的问题，而且这些问题往往都很诡异很难按照常规的思路去诊断。一旦出现权限的问题，个人建议第 1 和第 3 种方式来修改。

如果可执行文件 $ORACLE_HOME/bin/oracle 的属主或权限设定出了问题，那么可能会造成很多问题。例如：无法登陆到数据库、 ora-600 错误、“ TNS-12518: TNS:listener could not hand off client connection ”、“ Linux Error: 32: Broken pipe ”、“ ORA-12537: TNS:connection closed ”、访问 ASM 磁盘出错等。解决办法很简单，可以在 grid 用户下运行setasmgidwrap命令重新配置 $ORACLE_HOME/bin/oracle 可执行文件的权限和属主或者直接将 oracle 文件的权限修改为 6751 。 $ORACLE_HOME/bin/oracle 可执行文件正确属主应该是 oracle:asmadmin ，并且权限必须有 s 才可以，如下所示：

[root@orclalhr ~]$ which setasmgidwrap

/u01/app/11.2.0/grid/bin/setasmgidwrap

[root@orclalhr ~]$ setasmgidwrap -o /u01/app/oracle/product/11.2.0/dbhome_1/bin/oracle

[root@orclalhr ~]$ ll /u01/app/oracle/product/11.2.0/dbhome_1/bin/oracle

-rwsr-s--x 1 oracle asmadmin 232399083 Apr 21  2015 /u01/app/oracle/product/11.2.0/dbhome_1/bin/oracle

[root@orclalhr ~]# ll /u01/app/11.2.0/grid/bin/oracle

-rwsr-s--x. 1 grid oinstall 203972117 Jan  5  2015 /u01/app/11.2.0/grid/bin/oracle

[root@orclalhr ~]# chmod 6751 /u01/app/oracle/product/11.2.0/dbhome_1/bin/oracle

[root@orclalhr ~]# ll /u01/app/oracle/product/11.2.0/dbhome_1/bin/oracle

-rwsr-s--x 1 oracle asmadmin 232399083 Apr 21  2015 /u01/app/oracle/product/11.2.0/dbhome_1/bin/oracle

[root@orclalhr bin]# cd /u01/app/oracle/product/11.2.0/dbhome_1/bin/

How to check and fix file permissions on Grid Infrastructure environment (文档 ID 1931142.1)

In this Document

Goal

Solution

---

APPLIES TO:

Oracle Database - Enterprise Edition - Version 11.2.0.3 and later
Oracle Database - Standard Edition - Version 12.1.0.1 to 12.1.0.1 [Release 12.1]
Information in this document applies to any platform.

GOAL

To provide ways how to check, find and correct permissions for Grid Infrastructure (GI)  $ORACLE_HOME or .

SOLUTION

1. Validate the by using cluvfy tool.

$ cluvfy comp software -n all -verbose

This though only validates the binary files and theirs permissions. This is mentioned in unpublished bug 18407533 (closed as not a bug).

2. Check the permissions from the following 2 files which are created during Grid Infrastructure installation.

In $GRID_HOME/crs/utl (for 11.2 and 12.1.0.1) and /crs/utl/ (for 12.1.0.2) directory:

- crsconfig_dirs which has all directories listed in and their permissions

- crsconfig_fileperms which has list of files and their permissions and locations in .

3. The permissions can be reverted back to original values with rootcrs.pl or roothas.pl.  For versions 11.2.0.3.6 and higher, there is an option -init:    

Reset the permissions of all files and directories under Oracle . Please ensure CRS is not running while performing the followings:

For 11.2:
For clustered Grid Infrastructure, as root user

# cd /crs/install/
# ./rootcrs.pl -init

For Standalone Grid Infrastructure, as root user

# cd /crs/install/
# ./roothas.pl  -init

For 12c:
For clustered Grid Infrastructure, as root user

# cd /crs/install/
# ./rootcrs.sh -init

For Standalone Grid Infrastructure, as root user

# cd /crs/install/
# ./roothas.sh -init

4. If that does not work then permissions can be altered manually with information found from crsconfig_fileperms and crsconfig_dirs files.

Please note that changing the permissions manually is the last resort and shouldn't be used unless recommended by Oracle support or development.

MAIN CONTENT

PURPOSE

This script is intended to capture and restore the file permission of a given directory example - ORACLE_HOME. The script will create a output file called permission_ and permission_.cmd

 

REQUIREMENTS

The script needs to be run on command prompt of Unix platform .
Perl is required to execute this script
Shell is required to run the shell script .

CONFIGURING

Download and save the script on your server as permission.pl
Provide the execute permission on the script

INSTRUCTIONS

 Run the script from the location where you have downloaded and saved it

./permission.pl

CAUTION

This sample code is provided for educational purposes only and not supported by Oracle Support Services. It has been tested internally, however, and works as documented. We do not guarantee that it will work for you, so be sure to test it in your environment before relying on it.

Proofread this sample code before using it! Due to the differences in the way text editors, e-mail packages and operating systems handle text formatting (spaces, tabs and carriage returns), this sample code may not be in an executable state when you first receive it. Check over the sample code to ensure that errors of this type are corrected.

Note : This script can restore permission back to the point at which it was captured. It is not intended to reset the permission.

 

SCRIPT

Execute the script from the dollar ($) prompt

Steps to capture permission of a directory

 1. Download the script from  here
 2. Log in as "oracle" user
 3. copy the file to a location say /home/oracle/scripts
 4. Give execute permission

    $ chmod 755 permission.pl

 5. Execute the script to capture permission

  $ cd /home/oracle/scripts
  $ ./permission.pl

 

Script generates two files

a.  permission-  - This contains file permission in octal value, owner and group information of the files captured
b.  restore-perm-.cmd  - This contains command to change the permission, owner, and group of the captured files

Steps to restore captured permission of the directory

1. Give execute permission to file generated during capture

    chmod 755 restore-perm-.cmd

2. execute .cmd file to restore the permission and the ownership

    $ ./restore-perm-.cmd

 

Sample output of the script
