  RGW Server 配置

  在实际的生产环境，RGW1 和 RGW2 的配置参数是完全一样的。

root@ceph-mgr1:~# cat /etc/ceph/ceph.conf 
[global]
fsid = 5372c074-edf7-45dd-b635-16422165c17c
public_network = 192.168.100.0/24
cluster_network = 172.16.100.0/24
mon_initial_members = ceph-mon1,ceph-mon2,ceph-mon3
mon_host = 192.168.100.35,192.168.100.36,192.168.100.37
auth_cluster_required = cephx
auth_service_required = cephx
auth_client_required = cephx
 
[client.rgw.ceph-mgr1]
rgw_host = ceph-mgr1
rgw_dns_name = rgw.cncf.net
 
[client.rgw.ceph-mgr2]
rgw_host = ceph-mgr2
rgw_dns_name = rgw.cncf.net

 

  验证负载均衡器配置

  查看haproxy配置

root@haproxyA:~# vim /etc/haproxy/haproxy.cfg
listen ceph-radosgw-7480
   bind :80
   mode tcp
   server ceph-mgr1 192.168.100.38:7480 check inter 3s fall 3 rise 2
   server ceph-mgr2 192.168.100.39:7480 check inter 3s fall 3 rise 2

 

  客户端配置hosts解析haproxy地址后，浏览器访问

 

  安装 s3cmd 客户端

  s3cmd 是一个通过命令行访问 ceph RGW 实现创建存储同桶、上传、下载以及管理数据到对象存储的命令行客户端工具。

  CentOS：

[root@ansible yum.repos.d]# yum install s3cmd

 

  Ubuntu：

root@ceph-deploy:~# apt-cache madison s3cmd
root@ceph-deploy:~# apt install s3cmd

 

  配置 s3cmd 客户端执行环境

  客户端配置连接rgw的IP地址的dns解析

[root@ansible ~]# vim /etc/hosts
192.168.100.20 rgw.cncf.net   #此为rgw的负载均衡haproxy的ip地址

 

  使用s3cmd --configure以交互的方式配置，在当前用户家目录下生成配置文件

 

[root@ansible ~]# s3cmd --configure
 
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: 45CMIRWTFQY9DGJX7W1Z      #输入对象用户access key
Secret Key: EyFmlD51WWfCGbtxFYZcygwDc48QWMYyKs13nuDD     #输入对象用户secretkey
Default Region [US]:    #地区选项，直接回车
 
Use "s3.amazonaws.com" for S3 Endpoint and not modify it to the target Amazon S3.
S3 Endpoint [s3.amazonaws.com]: rgw.cncf.net    #输入对象存储RGW的域名，如果是默认端口没有修改,则rgw域名:7480
 
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]: rgw.cncf.net/%(bucket)  #输入rgw的bucket变量，格式为%(bucket)s.s3.amazonaws.com，也可以是s3.amazonaws.com/%(bucket)
 
Encryption password:   #直接输入回车，不需要加密
 
Path to GPG program [/usr/bin/gpg]:  #回车，指定gpg 命令路径，默认为/usr/bin/gpg，用于认证管理
 
 
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    #是否使用 https，输入no为不适用
 
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:    #回车，是否使用http代理
 
New settings:
  Access Key: 45CMIRWTFQY9DGJX7W1Z
  Secret Key: EyFmlD51WWfCGbtxFYZcygwDc48QWMYyKs13nuDD
  Default Region: US
  S3 Endpoint: rgw.cncf.net
  DNS-style bucket+hostname:port template for accessing a bucket: rgw.cncf.net/%(bucket)
  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] Y    #是否要测试连接对象rgw
Please wait, attempting to list all buckets...
Success. Your access key and secret key worked fine :-)   #测试成功
 
Now verifying that encryption works...
Not configured. Never mind.
 
Save settings? [y/N] y   #保存配置
Configuration saved to '/root/.s3cfg'   #将s3cmd配置文件保存到当前用户目录下

 

   验证s3cmd配置文件

[root@ansible ~]# egrep "access|secret|bucket" .s3cfg 
access_key = 45CMIRWTFQY9DGJX7W1Z
access_token = 
bucket_location = US
host_bucket = rgw.cncf.net/%(bucket)
secret_key = EyFmlD51WWfCGbtxFYZcygwDc48QWMYyKs13nuDD
website_endpoint = http://%(bucket)s.s3-website-%(location)s.amazonaws.com/

  创建 bucket 以验证权限

  存储空间（Bucket）是用于存储对象（Object）的容器，在上传任意类型的 Object 前，需要先创建 Bucket。

[root@ansible ~]# s3cmd mb s3://bucket01
Bucket 's3://bucket01/' created
 
[root@ansible ~]# s3cmd ls
2022-12-16 08:54  s3://bucket01

 

  验证上传数据

[root@ansible ~]# s3cmd put /etc/hosts s3://bucket01
upload: '/etc/hosts' -> 's3://bucket01/hosts'  [1 of 1]
 186 of 186   100% in    1s   112.99 B/s  done
[root@ansible ~]# s3cmd ls /etc/hosts s3://bucket01
2022-12-16 08:54  s3://bucket01

 

  验证下载文件

[root@ansible ~]# s3cmd get s3://bucket01/hosts /tmp/
download: 's3://bucket01/hosts' -> '/tmp/hosts'  [1 of 1]

 

  删除文件

[root@ansible ~]# s3cmd ls s3://bucket01
2022-12-16 08:59          186  s3://bucket01/hosts
[root@ansible ~]# s3cmd rm s3://bucket01/hosts
delete: 's3://bucket01/hosts'
[root@ansible ~]# s3cmd ls s3://bucket01
