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. 1、查看当前集群中的资源
2. #下面的查询可知，当前集群环境中存在两个service
3. [email protected]:~> crs_stat -ls | grep srv
4. ora....O4A.srv oracle         oinstall                 rwxrwxr--
5. ora....0g1.srv oracle         oinstall                 rwxrwxr--
6. #获得service的全称
7. [email protected]:~> crs_stat -p | grep srv
8. NAME=ora.GOBO4.GOBO4_SRV.GOBO4A.srv
9. NAME=ora.ora10g.hr_ora10g.ora10g1.srv
10. DESCRIPTION=ora.ora10g.hr_ora10g.ora10g1.srv
11. #下面通过crs_getperm获得资源的所有者即权限
12. [email protected]:~> crs_getperm ora.ora10g.hr_ora10g.ora10g1.srv
13. Name: ora.ora10g.hr_ora10g.ora10g1.srv
14. owner:oracle:rwx,pgrp:oinstall:rwx,other::r--,
15. #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
16. 2、crs_getperm与crs_setperm的用法
17. [email protected]:~> crs_getperm -h
18. Usage: crs_getperm resource_name [-u user|-g group] [-q]
19. #crs_getperm用法较为简单，后面接资源名，可选的为用户或组
20. [email protected]:~> crs_setperm -h  #此命令稍微较crs_getperm复杂
21. Usage: crs_setperm resource_name -u aclstring [-q]
22. crs_setperm resource_name -x aclstring [-q]
23. crs_setperm resource_name -o user_name [-q]
24. crs_setperm resource_name -g group_name [-q]
25. -u  Update the acl string
26. -x  Delete the acl string
27. -o  Change the owner of the resource
28. -g  Change the primary group of the resource
29. aclstring is one of the following:
30. user:<username>:rwx
31. 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
32. other::r--
33. 3、演示使用crs_setperm
34. [email protected]:~> su
35. Password:
36. #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
37. bo2dbp:/users/oracle # crs_setperm ora.ora10g.hr_ora10g.ora10g1.srv -o root
38. bo2dbp:/users/oracle # crs_setperm ora.ora10g.hr_ora10g.ora10g1.srv -g root
39. #查看修改之后，该资源的属主与属组已经发生变化
40. bo2dbp:/users/oracle # crs_getperm ora.ora10g.hr_ora10g.ora10g1.srv
41. Name: ora.ora10g.hr_ora10g.ora10g1.srv
42. owner:root:rwx,pgrp:root:rwx,other::r--,
43. #修改属组的权限，将其改为读，执行
44. bo2dbp:/users/oracle # crs_setperm ora.ora10g.hr_ora10g.ora10g1.srv -u pgrp:root:r-x
45. bo2dbp:/users/oracle # crs_getperm ora.ora10g.hr_ora10g.ora10g1.srv
46. Name: ora.ora10g.hr_ora10g.ora10g1.srv
47. owner:root:rwx,pgrp:root:r-x,other::r--,
48. #使用同样的方式将其修改回去。
49. bo2dbp:/users/oracle # crs_setperm ora.ora10g.hr_ora10g.ora10g1.srv -o oracle
50. bo2dbp:/users/oracle # crs_setperm ora.ora10g.hr_ora10g.ora10g1.srv -g oinstall
51. bo2dbp:/users/oracle # crs_setperm ora.ora10g.hr_ora10g.ora10g1.srv -u pgrp:oinstall:rwx

53. Name: ora.ora10g.hr_ora10g.ora10g1.srv
54. owner:oracle:rwx,pgrp:oinstall:rwx,other::r--,
55. bo2dbp:/users/oracle # su - oracle
56. #所有者的权限不允许修改
57. [email protected]:~> crs_setperm ora.ora10g.hr_ora10g.ora10g1.srv -u owner:oracle:r-x
58. CRS-0248:  Acl operation failed

62. CRS-0248:  Acl operation failed
63. #组权限可以修改
64. [email protected]:~> crs_setperm ora.ora10g.hr_ora10g.ora10g1.srv -u pgrp:oinstall:r-x

66. Name: ora.ora10g.hr_ora10g.ora10g1.srv
67. owner:oracle:rwx,pgrp:oinstall:r-x,other::r--,
68. #other也可以修改
69. [email protected]:~> crs_setperm ora.ora10g.hr_ora10g.ora10g1.srv -u other::rwx
