大家好,又见面了,我是你们的朋友全栈君。

设计部署架构如下:

安装ceph集群

  1. 准备好4台机器,设置好机器名和hosts:
代码语言:javascript复制
hostnamectl set-hostname cephadmin
...
  1. 设置好cephadmin到ceph1…的无密码登录
代码语言:javascript复制
ssh-keygen -t rsa
scp -p ~/.ssh/id_rsa.pub root@ceph1:/root/cephadmin.pub
... 
  1. 在cephadmin机器的/etc/yum.repos.d/目录下创建 ceph.repo:
代码语言:javascript复制
[Ceph]
name=Ceph packages for $basearch
baseurl=http://mirrors.163.com/ceph/rpm-jewel/el7/$basearch
enabled=1
gpgcheck=0
type=rpm-md
gpgkey=https://mirrors.163.com/ceph/keys/release.asc
priority=1

[Ceph-noarch]
name=Ceph noarch packages
baseurl=http://mirrors.163.com/ceph/rpm-jewel/el7/noarch
enabled=1
gpgcheck=0
type=rpm-md
gpgkey=https://mirrors.163.com/ceph/keys/release.asc
priority=1

[ceph-source]
name=Ceph source packages
baseurl=http://mirrors.163.com/ceph/rpm-jewel/el7/SRPMS
enabled=1
gpgcheck=0
type=rpm-md
gpgkey=https://mirrors.163.com/ceph/keys/release.asc
priority=1
  1. 在cephadmin上安装ceph-deploy
代码语言:javascript复制
mkdir ~/ceph-cluster
cd ~/ceph-cluster
yum install ceph-deploy

若安装ceph后遇到麻烦可以使用以下命令进行清除包和配置

代码语言:javascript复制
#ceph-deploy purge ceph1 ceph2 ceph3
#ceph-deploy purgedata ceph1 ceph2 ceph3
#ceph-deploy forgetkeys
  1. 初始化,创建配置文件
代码语言:javascript复制
cd ~/ceph-cluster
ceph-deploy new ceph1 ceph2 ceph3

在生成的ceph.conf中加入(写入[global] 段下)

代码语言:javascript复制
osd pool default size = 2
  1. 安装ceph
代码语言:javascript复制
ceph-deploy install cephadmin ceph1 ceph2 ceph3
  1. 配置初始monitors
代码语言:javascript复制
ceph-deploy mon create-initial
  1. 新建osd 分别在ceph1,ceph2,ceph3节点上创建osd1,osd2,osd3目录
代码语言:javascript复制
ssh ceph1
mkdir /var/local/ceph1
...

从cephadmin节点执行 ceph-deploy 来准备 并激活OSD

代码语言:javascript复制
ceph-deploy osd prepare ceph1:/var/local/osd1 ceph2:/var/local/osd2 ceph3:/var/local/osd3
ceph-deploy osd activate ceph1:/var/local/osd1 ceph2:/var/local/osd2 ceph3:/var/local/osd3

确保对 ceph.client.admin.keyring 有正确的操作权限。

代码语言:javascript复制
chmod  r /etc/ceph/ceph.client.admin.keyring

ceph已经安装完毕!可以使用ceph -s来测试一下:

代码语言:javascript复制
ceph -s

安装radosgw

  1. 为radosgw创建用户和keyring 为网关服务器创建Keyring:
代码语言:javascript复制
ceph-authtool --create-keyring /etc/ceph/ceph.client.radosgw.keyring
chmod  r /etc/ceph/ceph.client.radosgw.keyring

为网关实例client.radosgw.gateway生成一个名称和key:

代码语言:javascript复制
ceph-authtool /etc/ceph/ceph.client.radosgw.keyring -n client.radosgw.gateway --gen-key

为key添加权限

代码语言:javascript复制
ceph-authtool -n client.radosgw.gateway --cap osd 'allow rwx' --cap mon 'allow rwx' /etc/ceph/ceph.client.radosgw.keyring

将key添加到ceph storage cluster:

代码语言:javascript复制
ceph -k /etc/ceph/ceph.client.admin.keyring auth add client.radosgw.gateway -i /etc/ceph/ceph.client.radosgw.keyring
  1. 创建rgw相关的pool
代码语言:javascript复制
ceph osd pool create .rgw 128 128
ceph osd pool create .rgw.root 128 128
ceph osd pool create .rgw.control 128 128
ceph osd pool create .rgw.gc 128 128
ceph osd pool create .rgw.buckets 128 128
ceph osd pool create .rgw.buckets.index 128 128
ceph osd pool create .log 128 128
ceph osd pool create .intent-log 128 128
ceph osd pool create .usage 128 128
ceph osd pool create .users 128 128
ceph osd pool create .users.email 128 128
ceph osd pool create .users.swift 128 128
ceph osd pool create .users.uid 128 128
  1. 配置 /etc/ceph/ceph.conf里面关于rgw的部分:
代码语言:javascript复制
[client.radosgw.gateway]
host = cephadmin
keyring = /etc/ceph/ceph.client.radosgw.keyring
log file = /var/log/ceph/client.radosgw.gateway.log
rgw_frontends =civetweb port=80
rgw print continue = false

注意:radosgw有两种方式运行,一种是直接用civetweb的方式,其内置了一个比较小巧的http服务器mongoose,这种方式配置比较简单,不需要配置Apache httpd服务器。

注意其中的: keyring = /etc/ceph/ceph.client.radosgw.keyring

  1. 启动rgw
代码语言:javascript复制
radosgw -c /etc/ceph/ceph.conf -n client.radosgw.gateway 
  1. 现在rgw已经安装成功!可以访问一下cephadmin的80端口。会看到如下信息:
代码语言:javascript复制
<ListAllMyBucketsResult xmlns="http://s3.amazonaws.com/doc/2006-03-01/">
  <Owner>
    <ID>anonymous</ID>
    <DisplayName/>
  </Owner>
  <Buckets/>
</ListAllMyBucketsResult>

安装配置s3客户端工具

  1. 安装s3
代码语言:javascript复制
yum install s3cmd

验证安装是否成功:

代码语言:javascript复制
s3cmd --version
  1. 为s3访问创建一个用户
代码语言:javascript复制
radosgw-admin user create --secret="123" --uid="s3" --display-name="s3 user"

会得到返回信息,记住其中的access_key和secret_key,相当于s3用户的账号和密码。

如果发生错误需要删除用户,使用:

代码语言:javascript复制
radosgw-admin user rm --uid="s3"
  1. 配置s3cmd
代码语言:javascript复制
s3cmd --configure

注意输入以上生成的access_key和secret_key。 以上命令会生成/root/.s3cfg文件,需要进一步设置,主要是其中的: * cloudfont_host * host_base * host_bucket

我在cephadmin上配置的.s3cfg内容如下:

代码语言:javascript复制
[default]
access_key = APOQIZJAS0JV4GTN0AFF
access_token =
add_encoding_exts =
add_headers =
bucket_location = US
ca_certs_file =

gpg_passphrase =
guess_mime_type = True
host_base = cephadmin:80
host_bucket = %(bucket)s.cephadmin
human_readable_sizes = False
invalidate_default_index_on_cf = False
invalidate_default_index_root_on_cf = True
invalidate_on_cf = False
kms_key =

limitrate = 0
list_md5 = False
log_target_prefix =
long_listing = False
max_delete = -1
mime_type =
multipart_chunk_size_mb = 15
multipart_max_chunks = 10000
preserve_attrs = True
progress_meter = True
proxy_host =
proxy_port = 0
put_continue = False
recursive = False
recv_chunk = 65536
reduced_redundancy = False
requester_pays = False
restore_days = 1
restore_priority = Standard
secret_key = 123
send_chunk = 65536
server_side_encryption = False
signature_v2 = False
signurl_use_https = False
simpledb_host = sdb.amazonaws.com
skip_existing = False
socket_timeout = 300
stats = False
stop_on_error = False
storage_class =
urlencoding_mode = normal
use_http_expect = False
use_https = False
use_mime_magic = True
verbosity = WARNING
website_endpoint = http://%(bucket)s.s3-website-%(location)s.amazonaws.com/
website_error =
website_index = index.html

注意到: host_base = cephadmin:80 host_bucket = %(bucket)s.cephadmin 4. 开始测试!创建一个bucket:

代码语言:javascript复制
s3cmd mb s3://Aaa

注意要修改一下/etc/hosts,将Aaa.cephadmin指向cephadmin本机地址!!!

代码语言:javascript复制
10.0.83.41      cephadmin aaa.cephadmin

另外注意,bucket的名字必须是大写字母开头!!! 5. 列举buckets:

代码语言:javascript复制
s3cmd -v  ls
2018-04-17 10:25  s3://Aaa
