按照Redhat的文档,用chcat -- +Marketing filename 把filename文件添加到Marketing这个categories。但是无论使用在Marketing这个categories的hesidu用户还是root都不能添加。提示:
chcon: failed to change context of financerecords.txt to user_u:object_r:user_home_t:s0:c0: 权限不够

Summary

SELinux is preventing /usr/bin/chcon (unconfined_t) "relabelto" to financerecord.txt (bin_t).

Detailed Description

SELinux denied access requested by /usr/bin/chcon. It is not expected that this access is required by /usr/bin/chcon and this access may signal an intrusion attempt. It is also possible that the specific version or configuration of the application is causing it to require additional access.

Allowing Access

Sometimes labeling problems can cause SELinux denials. You could try to restore the default system file context for financerecord.txt, restorecon -v financerecord.txt If this does not work, there is currently no automatic way to allow this access. Instead, you can generate a local policy module to allow this access - see FAQ Or you can disable SELinux protection altogether. Disabling SELinux protection is not recommended. Please file a bug report against this package.

object_r In SELinux, roles are not utilized for objects when RBAC is being used. Roles are strictly for subjects. This is because roles are task-oriented and they group together entities which perform actions (for example, processes). All such entities are collectively referred to as subjects. For this reason, all objects have the role object_r, and the role is only used as a placeholder in the label.
