需求描述:需要关闭某些S3账号的删除权限，但是默认DELETE操作是由bucket WIRTE权限进行控制的，无法单独拆分DELETE操作。
解决思路：
1. 过滤前端HTTP请求的DELETE操作(需要写点代码)
2. 修改S3内置用户的metadata信息，本文用的就是这个方法。
root@demo# radosgw-admin metadata get user:s3user
{
"key": "user:s3user",
"ver": {
"tag": "_HUtHU_6yBqHTSzDLb9y8tjX",
"ver": 2
},
"mtime": 1493110079,
"data": {
"user_id": "s3user",
"display_name": "s3user",
"email": "",
"suspended": 0,
"max_buckets": 1000,
"auid": 0,
"subusers": [],
"keys": [
{
"user": "s3user",
"access_key": "xxx",
"secret_key": "xxx"
}
],
"swift_keys": [],
"caps": [],
"op_mask": "read, write,delete", #这里有delete权限
"default_placement": "",
"placement_tags": [],
"bucket_quota": {
"enabled": false,
"max_size_kb": -1,
"max_objects": -1
},
"user_quota": {
"enabled": false,
"max_size_kb": -1,
"max_objects": -1
},
"temp_url_keys": []
}
}root@demo# radosgw-admin metadata get user:s3user > s3user.json
修改生成的s3user.json文件，修改"op_mask"，删除“delete”字段
"op_mask": "read, write",
root@demo6# radosgw-admin metadata put user:s3user < s3user.json
root@demo# radosgw-admin metadata get user:s3user
{
"key": "user:s3user",
"ver": {
"tag": "_HUtHU_6yBqHTSzDLb9y8tjX",
"ver": 2
},
"mtime": 1493110079,
"data": {
"user_id": "s3user",
"display_name": "s3user",
"email": "",
"suspended": 0,
"max_buckets": 1000,
"auid": 0,
"subusers": [],
"keys": [
{
"user": "s3user",
"access_key": "xxx",
"secret_key": "xxx"
}
],
"swift_keys": [],
"caps": [],
"op_mask": "read, write", #delete权限没了
"default_placement": "",
"placement_tags": [],
"bucket_quota": {
"enabled": false,
"max_size_kb": -1,
"max_objects": -1
},
"user_quota": {
"enabled": false,
"max_size_kb": -1,
"max_objects": -1
},
"temp_url_keys": []
}
}from boto.s3.connection import S3Connectionimport boto endpoint = 's3.ceph.work'bucket_name = 'test1'access_key = 'xx'secret_key = 'xx'local_file = '/tmp/ct.shutdown'key_name = 'new_file'conn = boto.connect_s3( aws_access_key_id=access_key, aws_secret_access_key=secret_key, host=endpoint, is_secure=False, calling_format=boto.s3.connection.SubdomainCallingFormat(), validate_certs=True, ) bucket = conn.create_bucket(bucket_name) key_ = bucket.new_key(key_name) key_.set_contents_from_filename(local_file)#方法1bucket.delete_keys([key_name])#方法2# key_.delete()#方法3# bucket.delete_key(key_name)
上面3种方式都会提示403错误
Traceback (most recent call last): ..... boto.exception.S3ResponseError: S3ResponseError: 403 ForbiddenAccessDenied
