ECS：如何使用 ECS 設定和測試 s3cmd

安裝與組態

1.從其他資訊區段下載 s3cmd 工具。

2.解壓縮並安裝 s3cmd 工具：

命令：

# sudo tar xzf s3cmd-2.4.0.tar.gz
# sudo python setup.py install

3.執行 s3cmd 組態：

命令：

# s3cmd --configured

範例：

Enter new values or accept defaults in brackets with Enter.
Refer to user manual for detailed description of all options.

Access key and Secret key are your identifiers for Amazon S3. Leave them empty for using the env variables.
Access Key [XXXX]: objectuser for that bucket
Secret Key [XXX]: secret key
Default Region [US]:

Use "s3.amazonaws.com" for S3 Endpoint and not modify it to the target Amazon S3.
S3 Endpoint [XXXXX]: XX,XX.XX.XXX:9020

Use "%(bucket)s.s3.amazonaws.com" to the target Amazon S3. "%(bucket)s" and "%(location)s" vars can be used
if the target S3 system supports dns based buckets.
DNS-style bucket+hostname:port template for accessing a bucket [%(bucket)s.s3.amazonaws.com]:

Encryption password is used to protect your files from reading
by unauthorized persons while in transfer to S3
Encryption password:
Path to GPG program [/usr/bin/gpg]:

When using secure HTTPS protocol all communication with Amazon S3
servers is protected from 3rd party eavesdropping. This method is
slower than plain HTTP, and can only be proxied with Python 2.7 or newer
Use HTTPS protocol [Yes]: No

On some networks all internet access must go through a HTTP proxy.
Try setting it here if you can't connect to S3 directly
HTTP Proxy server name:

New settings:
  Access Key:XXXXX
  Secret Key:  XXXXXXXXX
  Default Region: US
  S3 Endpoint: XX.XX.XX.XXX:9020
  DNS-style bucket+hostname:port template for accessing a bucket: %(bucket)s.s3.amazonaws.com
  Encryption password:
  Path to GPG program: /usr/bin/gpg
  Use HTTPS protocol: False
  HTTP Proxy server name:
  HTTP Proxy server port: 0

Test access with supplied credentials? [Y/n]
Please wait, attempting to list all buckets...
Success. Your access key and secret key worked fine :-)

Now verifying that encryption works...
Not configured. Never mind.

Save settings? [y/N] y
Configuration saved to '/home/admin/.s3cfg'

4.執行 s3cmd 以列出所有容器：

命令：

# s3cmd ls

範例：

admin@ecsnode:~/mrx> s3cmd ls
2024-06-05 06:54  s3://bucket
2024-05-01 15:46  s3://s3cmd_bucket
2024-05-09 11:56  s3://s3cmd_bucket1
2024-05-08 09:18  s3://winscp

5.列出儲存桶的內容 （設定後現在為空白）：

命令：

admin@ecsnode:~/mrx> s3cmd ls s3://s3cmd_bucket
admin@ecsnode:~/mrx>

6.建立檔案並將其上傳到儲存桶：

命令：

# touch addressbook.xml

範例：

admin@ecsnode:~/mrx> s3cmd put addressbook.xml s3://s3cmd_bucket
upload: 'addressbook.xml' -> 's3://s3cmd_bucket/addressbook.xml'  [1 of 1]
 0 of 0     0% in    0s     0.00 B/s  done

7.列出容器的內容：

命令：

# s3cmd ls s3://s3cmd_bucket

範例：

admin@ecsnode:~/mrx> s3cmd ls s3://s3cmd_bucket
2024-07-03 11:36            0  s3://s3cmd_bucket/addressbook.xml
admin@ecsnode8:~/mrx>

8.從儲存器讀取檔案：

命令：

# s3cmd get s3://s3cmd_bucket/addressbook.xml

admin@ecsnode:~/mrx> s3cmd get s3://s3cmd_bucket/addressbook.xml
download: 's3://s3cmd_bucket/addressbook.xml' -> './addressbook.xml'  [1 of 1]
 0 of 0     0% in    0s     0.00 B/s  done

使用 PUT 進行寫入效能測試。

1.建立檔案：

命令：

# sudo fallocate -l 10G random10GB.bin

2.使用 time 命令監控將檔案random10BG.bin寫入s3cmd_bucket的持續時間：

命令：

# time ./s3cmd put <file> s3://<bucket>

範例：

admin@ecsnode:~> # time ./s3cmd put random10GB.bin s3://s3cmd_bucket
outputs:
upload: 'random10GB.bin' -> 's3://s3cmd_bucket/random10GB.bin'  [part 683 of 683, 10MB] [1 of 1]
 10485760 of 10485760   100% in    0s    57.68 MB/s  done

real    3m8.872s
user    1m29.483s
sys     0m19.052s

若要計算寫入回應時間：

• 3 分 8 秒 = 188 秒
• 10240 MB / 188 = 54 MB/s（每秒兆位元組）是上傳速度。

使用 GET 讀取效能測試。

使用監控讀取持續時間的時間命令：

命令：

# s3time s3cmd get s3://<bucket/>/<file>

範例：

admin@ecsnode:~> s3time s3cmd get s3://s3cmd_bucket/random10GB.bin
If 's3time' is not a typo you can use command-not-found to lookup the package that contains it, like this:
    cnf s3time
admin@ecsnode8:~> time s3cmd get s3://s3cmd_bucket/random10GB.bin
download: 's3://s3cmd_bucket/random10GB.bin' -> './random10GB.bin'  [1 of 1]
 10737418240 of 10737418240   100% in   38s   263.31 MB/s  done

real    0m39.172s
user    0m23.688s
sys     0m12.637s

若要計算讀取回應時間：

• 39 秒
• 10240 MB / 39 = 262.6 MB/s（每秒兆位元組）是下載速度。
