五 Ceph 对象网关

Ceph对象网关是构建在librados之上的对象存储接口，它为应用程序访问Ceph存储集群提供了一个RESTful风格的网关。Ceph对象存储支持2种接口：

  • 兼容S3: 提供了对象存储接口，兼容Amazon S3 RESTful接口的一个大子集。
  • 兼容Swift: 提供了对象存储接口，兼容Openstack Swift接口的一个大子集。

Ceph对象存储使用Ceph对象网关守护进程（radosgw），它是个与Ceph存储集群交互的FastCGI模块。因为它提供了与OpenStack Swift和Amazon S3兼容的接口，RADOS要有它自己的用户管理。Ceph对象网关可与CephFS客户端或Ceph块设备客户端共用一个存储集群。S3和Swift接口共用一个通用命名空间，所以你可以用一个接口写入数据、然后用另一个接口取出数据。

radosgw

5.1 安装 radosgw 服务并初始化:

root@ceph-deploy:~# su - cephyd
cephyd@ceph-deploy:~$ cd ceph-cluster/
cephyd@ceph-deploy:~/ceph-cluster$ ceph-deploy install   --rgw ceph-mgr1 ceph-mgr2

5.2 配置修改端口/记录日志

下面内容添加至ceph.conf

[client.rgw.ceph-mgr1] 
rgw_host = ceph-mgr1 
rgw_frontends = "civetweb port=8000 request_timeout_ms=30000 error_log_file=/tmp/civetweb.error.log access_log_file=/tmp/civetweb.access.log num_threads=100"

[client.rgw.ceph-mgr2] 
rgw_host = ceph-mgr2
rgw_frontends = "civetweb port=8000 request_timeout_ms=30000 error_log_file=/tmp/civetweb.error.log access_log_file=/tmp/civetweb.access.log num_threads=100"

配置同步过去

cephyd@ceph-deploy:~/ceph-cluster$ ceph-deploy --overwrite-conf config push ceph-mgr1 ceph-mgr2 ceph-mon1 ceph-mon2 ceph-mon3 ceph-deploy ceph-node1 ceph-node2 ceph-node3 ceph-node4

配置s3

cephyd@ceph-deploy:~/ceph-cluster$ 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: RNYDB5IUKJIQBZI2ZBB5
Secret Key: ybqB0VaeYR9WxGauO3xdyBQR9DKYX3PiEFj2b604
Default Region [US]:

Use "s3.amazonaws.com" for S3 Endpoint and not modify it to the target Amazon S3.
S3 Endpoint [s3.amazonaws.com]: 172.26.128.93:8000

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]: 172.26.128.93:8000/%(bucket)s

Encryption password is used to protect your files from reading
by unauthorized persons while in transfer to S3
Encryption password:
Path to GPG program [/usr/bin/gpg]:

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]: False

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:

New settings:
  Access Key: RNYDB5IUKJIQBZI2ZBB5
  Secret Key: ybqB0VaeYR9WxGauO3xdyBQR9DKYX3PiEFj2b604
  Default Region: US
  S3 Endpoint: 172.26.128.93:8000
  DNS-style bucket+hostname:port template for accessing a bucket: 172.26.128.93:8000/%(bucket)s
  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
Please wait, attempting to list all buckets...
Success. Your access key and secret key worked fine :-)

Now verifying that encryption works...
Not configured. Never mind.

Save settings? [y/N] y

六 Ceph dashboard

Ceph dashboard是通过一个web界面，对已经运行的ceph集群进行状态查看及功能配置等功能。

6.1 启用dashboard插件

ceph-mgr服务器安装包

cephyd@ceph-mgr1:~$ sudo echo "deb https://mirrors.tuna.tsinghua.edu.cn/ceph/debian-pacific bionic main" >> /etc/apt/sources.list
cephyd@ceph-mgr1:~$ sudo apt update
cephyd@ceph-mgr1:~$ sudo apt install ceph-mgr-dashboard

开启dashboard模块

cephyd@ceph-deploy:~/ceph-cluster$ sudo ceph mgr module -h
cephyd@ceph-deploy:~/ceph-cluster$ sudo ceph mgr module ls
cephyd@ceph-deploy:~/ceph-cluster$ sudo ceph mgr module enable dashboard

6.2 配置dashboard模块

cephyd@ceph-deploy:~/ceph-cluster$ sudo ceph config set mgr mgr/dashboard/ssl false
cephyd@ceph-deploy:~/ceph-cluster$ sudo ceph config set mgr mgr/dashboard/ceph-mgr1/server_addr 172.26.128.93
cephyd@ceph-deploy:~/ceph-cluster$ sudo ceph config set mgr mgr/dashboard/ceph-mgr1/server_port 8080
cephyd@ceph-deploy:~/ceph-cluster$ sudo ceph -s
  cluster:
    id:     003cb89b-8812-4172-a327-6a774c687c6c
    health: HEALTH_ok

  services:
    mon: 3 daemons, quorum ceph-mon1,ceph-mon2,ceph-mon3 (age 2w)
    mgr: ceph-mgr1(active, since 4m), standbys: ceph-mgr2
    mds: 2/2 daemons up, 2 standby
    osd: 6 osds: 6 up (since 2w), 6 in (since 2w)
    rgw: 2 daemons active (2 hosts, 1 zones)

  data:
    volumes: 1/1 healthy
    pools:   12 pools, 369 pgs
    objects: 448 objects, 554 MiB
    usage:   4.1 GiB used, 116 GiB / 120 GiB avail
    pgs:     369 active+clean
cephyd@ceph-deploy:~/ceph-cluster$ sudo ceph mgr services
{
    "dashboard": "http://172.26.128.93:8080/"
}

验证:

浏览器输入 http://172.26.128.93:8080/  访问

设置dashboard账户密码

cephyd@ceph-deploy:~/ceph-cluster$ touch pass.txt
cephyd@ceph-deploy:~/ceph-cluster$ echo  "12345678" > pass.txt
cephyd@ceph-deploy:~/ceph-cluster$ sudo ceph dashboard set-login-credentials yddash -i pass.txt

7.3 配置prometheus server数据并验证

cephyd@ceph-deploy:~$ sudo vim /usr/local/prometheus/prometheus.yml
  - job_name: 'ceph-node-data'
    static_configs:
      - targets: ['172.26.128.94:9100']
cephyd@ceph-deploy:~$ sudo systemctl restart prometheus

验证http://172.26.128.89:9090/targets

7.4 通过prometheus监控ceph服务

Ceph manager内部的模块中包含了prometheus的监控模块,并监听在每个manager节点的9283端口，该端口用于将采集到的信息通过http接口向prometheus提供数据。

启用prometheus监控模块：
