dashboard安装

1. 环境

   # ceph -s
cluster:
id: f885f732-2d84-4d5f-a6a4-8d02c8ae3834
health: HEALTH_OK

services:
mon: 1 daemons, quorum node1 (age 26m)

usage: 9.0 GiB used, 30 TiB / 30 TiB avail
pgs:

   




2. 所有mgr节点安装ceph-mgr-dashboard

   # yum install -y ceph-mgr-dashboard

   




3. 开启插件 禁用SSL

   # ceph mgr module enable dashboard
# ceph config set mgr mgr/dashboard/ssl false

   




4. 配置监听IP 0.0.0.0和端口

   # ceph config set mgr mgr/dashboard/server_addr 0.0.0.0
# ceph config set mgr mgr/dashboard/server_port 8443

   




5. 设置用户及密码

   # ceph dashboard ac-user-create admin mkj123. administrator

   




6. 查看模块是否开启

   # ceph mgr services
{
"dashboard": "http://node1:8080/"
}

   




7. 重启

   # ceph mgr module disable dashboard
# ceph mgr module enable dashboard

   




8. 再次查看配置

   # ceph mgr services
{
"dashboard": "http://node1:8443/"
}

dashboard启用rgw

1. 准备，安装rgw

   ceph-deploy rgw create node1 node2 node3

   




2. 推送配置文件和认证文件

   # ceph-deploy --overwrite-conf config push ceph_gateway
# ceph-deploy admin ceph_gateway

   




3. 查看是否安装成功

   
   

# curl http://node1:7480
anonymous


3. 创建rgw系统账户

   # radosgw-admin user create --uid=rgw --display-name=rgw --system
{
"user_id": "rgw",
"display_name": "rgw",
"email": "",
"suspended": 0,
"max_buckets": 1000,
"subusers": [],
"keys": [
{
"user": "rgw",
"access_key": "8WIF1QXSA2JQCFKG8VTD",
"secret_key": "SjMlQDclW75RnRuPp0FJM3tuYsCxOZ6P8to6ifgL"
}
],
"swift_keys": [],
"caps": [],
"op_mask": "read, write, delete",
"system": "true",
"default_placement": "",
"default_storage_class": "",
"placement_tags": [],
"bucket_quota": {
"enabled": false,
"check_on_raw": false,
"max_size": -1,
"max_size_kb": 0,
"max_objects": -1
},
"user_quota": {
"enabled": false,
"check_on_raw": false,
"max_size": -1,
"max_size_kb": 0,
"max_objects": -1
},
"temp_url_keys": [],
"type": "rgw",
"mfa_ids": []
}

   




4. 查看是否创建成功，并且记录下key

   # radosgw-admin user info --uid=rgw
{
"user_id": "rgw",
"display_name": "rgw",
"email": "",
"suspended": 0,
"max_buckets": 1000,
"subusers": [],
"keys": [
{
"user": "rgw",
"access_key": "8WIF1QXSA2JQCFKG8VTD",
"secret_key": "SjMlQDclW75RnRuPp0FJM3tuYsCxOZ6P8to6ifgL"
}
],
"swift_keys": [],
"caps": [],
"op_mask": "read, write, delete",
"system": "true",
"default_placement": "",
"default_storage_class": "",
"placement_tags": [],
"bucket_quota": {
"enabled": false,
"check_on_raw": false,
"max_size": -1,
"max_size_kb": 0,
"max_objects": -1
},
"user_quota": {
"enabled": false,
"check_on_raw": false,
"max_size": -1,
"max_size_kb": 0,
"max_objects": -1
},
"temp_url_keys": [],
"type": "rgw",
"mfa_ids": []
}

   




5. 为Dashboard设置access_key 和 secret_key

   # ceph dashboard set-rgw-api-access-key 8WIF1QXSA2JQCFKG8VTD
Option RGW_API_ACCESS_KEY updated
# ceph dashboard set-rgw-api-secret-key SjMlQDclW75RnRuPp0FJM3tuYsCxOZ6P8to6ifgL
Option RGW_API_SECRET_KEY updated

   




6. 禁用SSL

   # ceph dashboard set-rgw-api-ssl-verify False

   




7. 刷新dashboard即可看到rgw添加成功，最后查看集群状态

   # ceph -s
cluster:
id: cd2f3511-3d10-4ef7-81fd-ae5f75a68427
health: HEALTH_OK

services:
mon: 3 daemons, quorum node1,node2,node3 (age 6h)
mgr: node2(active, since 18m), standbys: node3, node1
mds: cephfs:1 {0=node2=up:active} 2 up:standby
osd: 14 osds: 14 up (since 6h), 14 in (since 15h)
rgw: 3 daemons active (node1, node2, node3)

task status:
scrub status:
mds.node2: idle

data:
pools: 10 pools, 832 pgs
objects: 15.92k objects, 55 GiB
usage: 132 GiB used, 52 TiB / 52 TiB avail
pgs: 832 active+clean

   

dashboard安装grafana

Ceph Dashboard中集成了grafana&prometheus，但需要手工启用，熟悉prometheus的人都知道其监控需要有exporter,ceph mgr模块中内置了prometheus exporter模块，所以无需要手工单独安装exporter,由于Ceph Dashboard中grafana还监控了Ceph存储节点的监控信息，所以每台存储节点中需要安装prometheus node exporter，借用redhat官方文档说明下这个架构：

1. 在grafana(admin)节点上配置grafana yum源。 如果配置了阿里源 则不需要配置此源

   # vim /etc/yum.repos.d/grafana.repo
[grafana]
name=grafana
baseurl=https://mirrors.cloud.tencent.com/grafana/yum/el7/
enabled=1
gpgcheck=0

   




2. 安装grafana。

   # yum -y install grafana -y

   




3. 在/etc/grafana/grafana.ini中配置Grafana 以适应匿名模式,并修改grafana默认风格，否者默认为暗黑，集成到ceph dashboard中风格不匹配。

   # vim /etc/grafana/grafana.ini
default_theme = light
[auth.anonymous]
enabled = true
org_name = Main Org.
org_role = Viewer


   注意Main Org后面的个点“.”不要忘记！

   在较新版本的Grafana（从6.2.0-beta1开始）中，allow_embedding引入了一个名为的新设置 。该设置需要明确设置true，Ceph Dashboard中的Grafana集成才能正常使用，因为其默认值为false。

   
   



4. 启动grafana并设为开机自启。

   #systemctl start grafana-server.service
#systemctl status grafana-server.service
#systemctl enable grafana-server.service

   




5. 安装grafana插件。

   # grafana-cli plugins install vonage-status-panel
installing vonage-status-panel @ 1.0.10
from url: https://grafana.com/api/plugins/vonage-status-panel/versions/1.0.10/download
into: /var/lib/grafana/plugins
✔ Installed vonage-status-panel successfully
Restart grafana after installing plugins .
# grafana-cli plugins install grafana-piechart-panel
installing grafana-piechart-panel @ 1.6.1
from url: https://grafana.com/api/plugins/grafana-piechart-panel/versions/1.6.1/download
into: /var/lib/grafana/plugins
✔ Installed grafana-piechart-panel successfully
Restart grafana after installing plugins .

   




6. 重启服务

   #systemctl restart grafana-server

   




7. 登录: http://192.168.10.15:3000/?orgId=1进去后默认用户名密码admin/admin,查看安装的插件

   

   
   

dashboard安装prometheus

1. 从官方下载prometheus软件包并解压。https://prometheus.io/download/
