使用crs_setperm修改RAC资源的所有者及权限
Oracle RAC 集群中,对于各种资源的管理,也存在所有者与权限的问题。crs_getperm与crs_setperm则是这样的一对命令,主要用于查看与修改集群中resource的owner,group以及权限等,下面通过具体的演示来获得其使用方法。
[python] view plain copy print?
- 1、查看当前集群中的资源
- #下面的查询可知,当前集群环境中存在两个service
- oracle@bo2dbp:~> crs_stat -ls | grep srv
- ora....O4A.srv oracle oinstall rwxrwxr--
- ora....0g1.srv oracle oinstall rwxrwxr--
- #获得service的全称
- oracle@bo2dbp:~> crs_stat -p | grep srv
- NAME=ora.GOBO4.GOBO4_SRV.GOBO4A.srv
- NAME=ora.ora10g.hr_ora10g.ora10g1.srv
- DESCRIPTION=ora.ora10g.hr_ora10g.ora10g1.srv
- #下面通过crs_getperm获得资源的所有者即权限
- oracle@bo2dbp:~> crs_getperm ora.ora10g.hr_ora10g.ora10g1.srv
- Name: ora.ora10g.hr_ora10g.ora10g1.srv
- owner:oracle:rwx,pgrp:oinstall:rwx,other::r--,
- #上面owner即为所有者,pgrp表示所有者,other则为其他用户,每个后面跟的都是其对应的权限
- 2、crs_getperm与crs_setperm的用法
- oracle@bo2dbp:~> crs_getperm -h
- Usage: crs_getperm resource_name [-u user|-g group] [-q]
- #crs_getperm用法较为简单,后面接资源名,可选的为用户或组
- oracle@bo2dbp:~> crs_setperm -h #此命令稍微较crs_getperm复杂
- Usage: crs_setperm resource_name -u aclstring [-q]
- crs_setperm resource_name -x aclstring [-q]
- crs_setperm resource_name -o user_name [-q]
- crs_setperm resource_name -g group_name [-q]
- -u Update the acl string
- -x Delete the acl string
- -o Change the owner of the resource
- -g Change the primary group of the resource
- aclstring is one of the following:
- user:<username>:rwx
- group:<groupname>:r-x #当心这里的group用法,如果直接使用group修改权限会收到错误提示
- other::r--
- 3、演示使用crs_setperm
- oracle@bo2dbp:~> su
- Password:
- #下面分别修改资源hr_ora10g的资源所有者和所属组,将其全部改为roo权限
- bo2dbp:/users/oracle # crs_setperm ora.ora10g.hr_ora10g.ora10g1.srv -o root
- bo2dbp:/users/oracle # crs_setperm ora.ora10g.hr_ora10g.ora10g1.srv -g root
- #查看修改之后,该资源的属主与属组已经发生变化
- bo2dbp:/users/oracle # crs_getperm ora.ora10g.hr_ora10g.ora10g1.srv
- Name: ora.ora10g.hr_ora10g.ora10g1.srv
- owner:root:rwx,pgrp:root:rwx,other::r--,
- #修改属组的权限,将其改为读,执行
- bo2dbp:/users/oracle # crs_setperm ora.ora10g.hr_ora10g.ora10g1.srv -u pgrp:root:r-x
- bo2dbp:/users/oracle # crs_getperm ora.ora10g.hr_ora10g.ora10g1.srv
- Name: ora.ora10g.hr_ora10g.ora10g1.srv
- owner:root:rwx,pgrp:root:r-x,other::r--,
- #使用同样的方式将其修改回去。
- bo2dbp:/users/oracle # crs_setperm ora.ora10g.hr_ora10g.ora10g1.srv -o oracle
- bo2dbp:/users/oracle # crs_setperm ora.ora10g.hr_ora10g.ora10g1.srv -g oinstall
- bo2dbp:/users/oracle # crs_setperm ora.ora10g.hr_ora10g.ora10g1.srv -u pgrp:oinstall:rwx
- bo2dbp:/users/oracle # crs_getperm ora.ora10g.hr_ora10g.ora10g1.srv
- Name: ora.ora10g.hr_ora10g.ora10g1.srv
- owner:oracle:rwx,pgrp:oinstall:rwx,other::r--,
- bo2dbp:/users/oracle # su - oracle
- #所有者的权限不允许修改
- oracle@bo2dbp:~> crs_setperm ora.ora10g.hr_ora10g.ora10g1.srv -u owner:oracle:r-x
- CRS-0248: Acl operation failed
- oracle@bo2dbp:~> crs_setperm ora.ora10g.hr_ora10g.ora10g1.srv -u owner:oracle:rw-
- CRS-0248: Acl operation failed
- oracle@bo2dbp:~> crs_setperm ora.ora10g.hr_ora10g.ora10g1.srv -u owner:oracle:-wx
- CRS-0248: Acl operation failed
- #组权限可以修改
- oracle@bo2dbp:~> crs_setperm ora.ora10g.hr_ora10g.ora10g1.srv -u pgrp:oinstall:r-x
- oracle@bo2dbp:~> crs_getperm ora.ora10g.hr_ora10g.ora10g1.srv
- Name: ora.ora10g.hr_ora10g.ora10g1.srv
- owner:oracle:rwx,pgrp:oinstall:r-x,other::r--,
- #other也可以修改
- oracle@bo2dbp:~> crs_setperm ora.ora10g.hr_ora10g.ora10g1.srv -u other::rwx
- oracle@bo2dbp:~> crs_getperm ora.ora10g.hr_ora10g.ora10g1.srv
- Name: ora.ora10g.hr_ora10g.ora10g1.srv
- owner:oracle:rwx,pgrp:oinstall:r-x,other::rwx,
