cephCEPH RGW初使用-RGW1

采得百花成蜜后，为谁辛苦为谁甜。这篇文章主要讲述cephCEPH RGW初使用-RGW1相关的知识，希望能为你提供帮助。
?
在这篇文章中，我记录在fedora-28 虚拟机上创建最小 CEPH RGW 集群的粗略的笔记和命令。
操作系统版本：
# cat /etc/redhat-release
Fedora release 28 (Twenty Eight)
系统要求：

> 25 GB storage space where ceph source code needs to be built
preferably > 8GB ram

从源代码手动安装：To build ceph code:
Source: ??http://docs.ceph.com/docs/mimic/install/build-ceph/??

git clone ??https://github.com/ceph/ceph.git??
cd ceph/
git status
git submodule update –force –init –recursive
./install-deps.sh#安装依赖
./do_cmake.sh
cd build/
make
make install
ln -s /usr/local/lib64/librado* /usr/lib64/

在虚拟机上本地启动 ceph 集群：

cd /../ceph/build
MON=1 OSD=1 MDS=1 MGR=1 RGW=1 ..//src/vstart.sh -n -d

所列的每项服务都创建一个

ps aux | grep ceph

现在创建 rgw 用户/子用户 users/sub-users:
Source:- (??http://docs.ceph.com/docs/mimic/radosgw/admin/??)
我们需要为 S3 访问创建用户和为 SWIFT 创建子用户。
radosgw-admin user create –uid=rgwuser –display-name=”RGW user”
#默认情况下生成访问密钥和秘密密钥(access-key and secret key)。检查用户信息

radosgw-admin subuser create –uid=rgwuser –subuser=rgwuser:swift –access=full
radosgw-admin caps add –uid=rgwuser –caps=”users=*; buckets=*”

（增加能力）

radosgw-admin 用户信息 –uid=rgwuser

检查用户/子用户信息

测试 s3 访问：（使用 python-boto）
Source: ??http://docs.ceph.com/docs/mimic/radosgw/s3/python/??

dnf 安装 python-boto
以下是各种功能的示例脚本 -

import boto
import boto.s3.connection

access_key = "ZGX5BVGID059T7DJLM0S"
secret_key = "koe8DFgGwNk5sQTRVxHaDiEgYQDVj8XVXMdZ4ULd"

boto.config.add_section(\'s3\')
boto.config.set(\'s3\', \'use-sigv4\', \'True\')

#create connection
conn = boto.connect_s3(
aws_access_key_id = access_key,
aws_secret_access_key = secret_key,
host = \'s3.localhost\',
port = 8000,
is_secure=False,
calling_format = boto.s3.connection.OrdinaryCallingFormat(),
)

#create bucket
bucket = conn.create_bucket(\'my-new-bucket\')

#list buckets created
for bucket in conn.get_all_buckets():
print "{name}\\t{created}".format(
name = bucket.name,
created = bucket.creation_date,
)

#insert file "hello.txt" as object into the bucket
key = bucket.new_key(\'hello.txt\')
key.set_contents_from_string(\'Hello World!\') #write contents

#list objects
for key in bucket.list():
print "{name}\\t{size}\\t{modified}".format(
name = key.name,
size = key.size,
modified = key.last_modified,
)

#connect to specific bucket and object
my_bucket = conn.get_bucket(\'my-new-bucket\')
hello_key = my_bucket.get_key(\'hello.txt\')

# make hello.txt object public
hello_key.set_canned_acl(\'public-read\')

#generate web-url for the file hello.txt
hello_url = hello_key.generate_url(0, query_auth=False, force_http=True)
print hello_url

#copy hello.txt to local filesystem
key.get_contents_to_filename(\'/workspace/scripts/sample_hello.txt\')

通过 SWIFT 访问进行测试：

dnf 安装 python-setuptools
easy_install pip
pip install – 升级安装工具
pip install –upgrade python-swiftclient
列出已经创建的容器：

swift -A ??http://??{IP ADDRESS}:{port}/auth/1.0 -U testuser:swift -K ‘{swift_secret_key}’ list
eg: #swift -A http://localhost:8000/auth/1.0 -U rgwuser:swift -K \'5euZSGD4ikdo4ppVYNiQ1czRXSACHkuO367S41Po\' list my-new-bucket

将对象插入容器：

# echo " swift access " > swift_file
# swift -A http://localhost:8000/auth/1.0 -U rgwuser:swift -K \'5euZSGD4ikdo4ppVYNiQ1czRXSACHkuO367S41Po\' upload my-new-bucket swift_file
swift_file
# swift -A http://localhost:8000/auth/1.0 -U rgwuser:swift -K \'5euZSGD4ikdo4ppVYNiQ1czRXSACHkuO367S41Po\' list my-new-bucket
hello.txt
swift_file

下载一个对象：

#swift -A http://localhost:8000/auth/1.0 -U rgwuser:swift -K \'5euZSGD4ikdo4ppVYNiQ1czRXSACHkuO367S41Po\' download my-new-bucket hello.txt
hello.txt [auth 0.003s, headers 0.008s, total 0.008s, 0.002 MB/s]
# cat hello.txt
Hello World!
