这期内容当中小编将会给大家带来有关rgw用户中的caps指的是什么，文章内容丰富且以专业的角度为大家分析和叙述，阅读完这篇文章希望大家可以有所收获。
可以用以下命令为用户添加所有的caps，拥有对应的cap的用户可以操作不仅限与属于用户自己的桶和对象和其他用户，可以看作拥有管理员的某种权限
radosgw-admin caps add --uid=admin --caps="users=*;buckets=*;metadata=*;usage=*;zone=*"
*代表read和write
可以按照以下方式为不同的用户添加不同的caps，但是不建议给普通用户开启任何caps
testcaps1用户 radosgw-admin caps add --uid=testcaps1 --caps="users=*" testcaps2用户 radosgw-admin caps add --uid=testcaps2 --caps="buckets=*" testcaps3用户 radosgw-admin caps add --uid=testcaps3 --caps="metadata=*" testcaps4用户 radosgw-admin caps add --uid=testcaps4 --caps="usage=*" testcaps5用户 radosgw-admin caps add --uid=testcaps5 --caps="zone=*"
对照http://docs.ceph.com/docs/jewel/radosgw/adminops/的介绍
用户拥有 usage=read 的可以查看调用admin rest api 的 usage 接口
于是只有testcaps4是可以
