|
|||
|
||||
To use the Google Cloud Storage backend you have to install the suggested
|
||||
library using the command `composer require google/cloud-storage`.
|
||||
|
||||
#### Using S3 Storage
|
||||
Similar to Google Cloud Storage, you can choose S3 as storage backend. It uses
|
||||
the AWS SDK for PHP, but can also talk to a Rados gateway as part of a CEPH
|
||||
cluster. To use this backend, you first have to install the SDK in the
|
||||
document root of PrivateBin: `composer require aws/aws-sdk-php`. You have to
|
||||
create the S3 bucket on the CEPH cluster before using the S3 backend.
|
||||
|
||||
In the `[model]` section of cfg/conf.php, set `class` to `S3Storage`.
|
||||
|
||||
You can set any combination of the following options in the `[model_options]`
|
||||
section:
|
||||
|
||||
* region
|
||||
* version
|
||||
* endpoint
|
||||
* bucket
|
||||
* prefix
|
||||
* accesskey
|
||||
* secretkey
|
||||
* use_path_style_endpoint
|
||||
|
||||
By default, prefix is empty. If set, the S3 backend will place all PrivateBin
|
||||
data beneath this prefix.
|
||||
|
||||
For AWS, you have to provide at least `region`, `bucket`, `accesskey`, and
|
||||
`secretkey`.
|
||||
|
||||
For CEPH, follow this example:
|
||||
|
||||
```
|
||||
region = ""
|
||||
version = "2006-03-01"
|
||||
endpoint = "https://s3.my-ceph.invalid"
|
||||
use_path_style_endpoint = true
|
||||
bucket = "my-bucket"
|
||||
accesskey = "my-rados-user"
|
||||
secretkey = "my-rados-pass"
|
||||
```

* S3.php
|

*
|
||||
* an S3 compatible data backend for PrivateBin with CEPH/RadosGW in mind
|
||||
* see https://docs.ceph.com/en/latest/radosgw/s3/php/
|
||||
* based on lib/Data/GoogleCloudStorage.php from PrivateBin version 1.4.0
|

*
|

* @link https://github.com/PrivateBin/PrivateBin
|

* @copyright 2022 Felix J. Ogris (https://ogris.de/)
|

* @license https://www.opensource.org/licenses/zlib-license.php The zlib/libpng License
|
||||
* @version 1.4.1
|
||||
*
|
||||
* Installation:
|
||||
* 1. Make sure you have composer.lock and composer.json in the document root of your PasteBin
|
||||
* 2. If not, grab a copy from https://github.com/PrivateBin/PrivateBin
|
||||
* 3. As non-root user, install the AWS SDK for PHP:
|
||||
* composer require aws/aws-sdk-php
|
||||
* (On FreeBSD, install devel/php-composer2 prior, e.g.: make -C /usr/ports/devel/php-composer2 install clean)
|
||||
* 4. In cfg/conf.php, comment out all [model] and [model_options] settings
|
||||
* 5. Still in cfg/conf.php, add a new [model] section:
|
||||
* [model]
|
||||
* class = S3Storage
|
||||
* 6. Add a new [model_options] as well, e.g. for a Rados gateway as part of your CEPH cluster:
|
||||
* [model_options]
|
||||
* region = ""
|
||||
* version = "2006-03-01"
|
||||
* endpoint = "https://s3.my-ceph.invalid"
|
||||
* use_path_style_endpoint = true
|
||||
* bucket = "my-bucket"
|
||||
* prefix = "privatebin" (place all PrivateBin data beneath this prefix)
|
||||
* accesskey = "my-rados-user"
|
||||
* secretkey = "my-rados-pass"
