Editor to share with you how to build RGW in Ceph deployment, I believe most people do not know much about it, so share this article for your reference, I hope you can learn a lot after reading this article, let's learn about it!

Deploy Ceph RGW

Enter the my-cluster directory described above.

Cd my-cluster modifies the default port (optional)

RGW uses Civetweb as its Web Sevice by default, while Civetweb uses port 7480 by default to provide services. If you want to modify the port (such as port 80), you need to modify the configuration file of Ceph. Add a section [client.rgw.] to the configuration file, where you need to modify the hostname to RGW. As follows:

[client.rgw.node4] rgw_frontends = "civetweb port=80"

The configuration file is then pushed to the RGW node.

$ceph-deploy-- overwrite-conf config push node4 installs CEPH OBJECT GATEWAY

The format is:

$ceph-deploy install-- rgw [...]

Since we have only one RGW in our environment, execute the command:

$ceph-deploy install-- rgw node4 manages the RGW node

The Ceph CLI tool needs to be run in administrator mode, so you need to execute the following command:

$ceph-deploy admin node4 installs the RGW instance

Execute the command:

$ceph-deploy rgw create node4

Once RGW is running, we can access it through port 7480 (if not modified). Such as:

Http://node4:7480

If RGW is working properly, it should return similar information:

Anonymous

Note: the rest of the steps to create a user should be run on the RGW node.

Create S3 user

To access RGW normally, you need to create the corresponding RGW user and give the appropriate permissions, and the radosgw-admin command implements these functions.

Create a user named testuser by executing the following command:

Radosgw-admin user create-- uid= "testuser"-- display-name= "First User"

The output of the command is roughly as follows:

{"user_id": "testuser", "display_name": "First User", "email": "," suspended ": 0," max_buckets ": 1000," auid ": 0," subusers ": []," keys ": [{" user ":" testuser "," access_key ":" I0PJDPCIYZ665MW88W9R "," secret_key ":" dxaXZ8U90SXydYzyS5ivamEP20hkLSUViiaR+ZDA "}] "swift_keys": [], "caps": [], "op_mask": "read, write, delete", "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": []}

Note: you need to remember to return the values of keys- > access_key and keys- > secret_key in the result, which are used to confirm the access of S3 interface.

Create a Swift user

The Swift user is created as a sub-user subuser, execute the following command:

$radosgw-admin subuser create-uid=testuser-subuser=testuser:swift-access=full

The output is roughly as follows:

"user_id": "testuser", "display_name": "First User", "email": "," suspended ": 0," max_buckets ": 1000," auid ": 0," subusers ": [{" id ":" testuser:swift "," permissions ":" full-control "}]," keys ": [{" user ":" testuser:swift " "access_key": "3Y1LNW4Q6X0Y53A52DET", "secret_key": ""}, {"user": "testuser", "access_key": "I0PJDPCIYZ665MW88W9R", "secret_key": "dxaXZ8U90SXydYzyS5ivamEP20hkLSUViiaR+ZDA"}], "swift_keys": [{"user": "testuser:swift", "secret_key": "244+fz2gSqoHwR3lYtSbIyomyPHf3i7rgSJrF\ / IA"}] "caps": [], "op_mask": "read, write, delete", "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": []

Note: you need to remember to return the value of swift_keys- > secret_key in the result, which is used for the Swift API access confirmation.

Test S3 interface

You need to create a Python test script to test S3 access. The script connects to the RGW, creates a bucket, and lists all the bucket. Where the values of the variables access_key and secret_access come from the keys- > access_key and keys- > secret_key returned by the radosgw-admin command when the S3 user command is created.

Perform the following steps to first install the python-boto library, which is used to connect to S3:

$apt-get install python-boto

Create and edit the Python script:

$vi s3test.pyimport boto.s3.connectionaccess_key = 'I0PJDPCIYZ665MW88W9R'secret_key =' dxaXZ8U90SXydYzyS5ivamEP20hkLSUViiaR+ZDA'conn = boto.connect_s3 (aws_access_key_id=access_key, aws_secret_access_key=secret_key, host=' {hostname}', port= {port}, is_secure=False, calling_format=boto.s3.connection.OrdinaryCallingFormat () ) bucket = conn.create_bucket ('my-new-bucket') for bucket in conn.get_all_buckets (): print "{name} {created}" .format (name=bucket.name, created=bucket.creation_date,)

Replace {hostname}, {port} with real-world hostname (or ip) and RGW ports. Execute the command to test:

$python s3test.py

The output should look like this:

My-new-bucket-2 2017-02-19T04:34:17.530Z5.4.8 Test Swift Interface

Swfit can be accessed from the command line. First install the relevant software packages:

$apt-get install python-setuptools$ apt-get install python-swiftclient

Execute the following command, Fan Wen Swift interface:

$swift-A http://{IP ADDRESS}: {port} / auth/1.0-U testuser:swift-K'{swift_secret_key} 'list

Replace relevant parameters such as {IP ADDRESS}, {port}, {swift_secret_key}, where {swift_secret_key} is the value of swift_keys- > secret_key returned by the radosgw-admin command when the Swift user is created. The normal output should be:
