Contoh 1: Untuk mengatur pencatatan kebijakan bucket
put-bucket-logging
Contoh berikut menetapkan kebijakan logging untuk MyBucket. Pertama, berikan izin utama layanan logging dalam kebijakan bucket Anda menggunakanput-bucket-policy
perintah.aws s3api put-bucket-policy \ --bucket
MyBucket
\ --policyfile://policy.json
Isi dari
policy.json
:{ "Version": "2012-10-17", "Statement": [ { "Sid": "S3ServerAccessLogsPolicy", "Effect": "Allow", "Principal": {"Service": "logging.s3.amazonaws.com"}, "Action": "s3:PutObject", "Resource": "arn:aws:s3:::MyBucket/Logs/*", "Condition": { "ArnLike": {"aws:SourceARN": "arn:aws:s3:::SOURCE-BUCKET-NAME"}, "StringEquals": {"aws:SourceAccount": "SOURCE-AWS-ACCOUNT-ID"} } } ] }
Untuk menerapkan kebijakan pencatatan, gunakan
put-bucket-logging
.aws s3api put-bucket-logging \ --bucket
MyBucket
\ --bucket-logging-statusfile://logging.json
Isi dari
logging.json
:{ "LoggingEnabled": { "TargetBucket": "MyBucket", "TargetPrefix": "Logs/" } }
put-bucket-policy
Perintah diperlukan untuk memberikans3:PutObject
izin kepada prinsipal layanan logging.Untuk informasi selengkapnya, lihat Logging Akses Server Amazon S3 di Panduan Pengguna Amazon S3.
Contoh 2: Untuk menetapkan kebijakan bucket untuk akses log hanya ke satu pengguna
put-bucket-logging
Contoh berikut menetapkan kebijakan logging untuk MyBucket. Bagian AWS pengguna bob@example.com akan memiliki kontrol penuh atas file log, dan tidak ada orang lain yang memiliki akses. Pertama, berikan izin S3 denganput-bucket-acl
.aws s3api put-bucket-acl \ --bucket
MyBucket
\ --grant-writeURI=http://acs.amazonaws.com/groups/s3/LogDelivery
\ --grant-read-acpURI=http://acs.amazonaws.com/groups/s3/LogDelivery
Kemudian terapkan kebijakan logging menggunakan
put-bucket-logging
.aws s3api put-bucket-logging \ --bucket
MyBucket
\ --bucket-logging-statusfile://logging.json
Isi dari
logging.json
:{ "LoggingEnabled": { "TargetBucket": "MyBucket", "TargetPrefix": "MyBucketLogs/", "TargetGrants": [ { "Grantee": { "Type": "AmazonCustomerByEmail", "EmailAddress": "bob@example.com" }, "Permission": "FULL_CONTROL" } ] } }
put-bucket-acl
perintah diperlukan untuk memberikan sistem pengiriman log S3 izin yang diperlukan (izin tulis dan baca-acp).Untuk informasi selengkapnya, lihat Logging Akses Server Amazon S3 di Panduan Pengembang Amazon S3.
