## 14.1 创建api

```
# 在任意控制节点操作，以controller1节点为例；
# 调用相关服务需要认证信息，加载环境变量脚本即可
[root@controller1 ~]# . admin-openrc
```

* 创建ceilometer用户

```
openstack user create --domain default --password-prompt ceilometer
User Password:
Repeat User Password:
+---------------------+----------------------------------+
| Field               | Value                            |
+---------------------+----------------------------------+
| domain_id           | default                          |
| enabled             | True                             |
| id                  | ff182d36698346c6a394e47d8f0f2d77 |
| name                | ceilometer                       |
| options             | {}                               |
| password_expires_at | None                             |
+---------------------+----------------------------------+
```

* 为ceilometer赋权

```
openstack role add --project service --user ceilometer admin
```

* 创建gnocchi用户

```
openstack user create --domain default --password-prompt gnocchi
User Password:
Repeat User Password:
+---------------------+----------------------------------+
| Field               | Value                            |
+---------------------+----------------------------------+
| domain_id           | default                          |
| enabled             | True                             |
| id                  | 14ff2b0d3c67455b820e1a7786e76b18 |
| name                | gnocchi                          |
| options             | {}                               |
| password_expires_at | None                             |
+---------------------+----------------------------------+

## 14.6 grafana展示数据

### 14.6.1 安装grafana

```
# install grafana
cat > /etc/yum.repos.d/grafana.repo << 'EOF'
[grafana]
name=grafana
baseurl=https://packagecloud.io/grafana/stable/el/7/$basearch
gpgkey=https://packagecloud.io/gpg.key https://grafanarel.s3.amazonaws.com/RPM-GPG-KEY-grafana
enabled=0
gpgcheck=1
EOF

# yum install grafana
yum --enablerepo=grafana -y install grafana initscripts fontconfig
```

### 14.6.2 配置grafana

```
vi /etc/grafana/grafana.ini

# 编辑如下内容,我这里配置http_addr=10.50.100.13 http_port = 3333
 30 [server]
 31 # Protocol (http, https, socket)
 32 ;protocol = http
 33
 34 # The ip address to bind to, empty will bind to all interfaces
 35 ;http_addr =
 36
 37 # The http port  to use
 38 ;http_port = 3000
 39
 40 # The public facing domain name used to access grafana from a browser
 41 ;domain = localhost
```

### 14.6.4 启动grafana

```
# start and enable grafana
sudo systemctl start grafana-server
sudo systemctl enable grafana-server
sudo systemctl status grafana-server
```

### 14.6.5 配置gnocchi启用cors

```
# 配置，allowed_origin是grafana监听的地址
vi /etc/gnocchi/gnocchi.conf
[cors]
allowed_origin = http://10.50.100.13:3333

# 重启gnocchi
systemctl restart gnocchi-api.service  gnocchi-metricd.service 
```

### 14.6.6 配置keyston启用cors（可选）
如果启用grafana的keystone认证的话，需要配置keystone的cors，配置方法如下：
```
vi /etc/keystone/keystone.conf

[cors]
allowed_origin = http://10.50.100.13:3333

# 重启
systemctl restart httpd memcached
```

### 14.6.7 安装gnocchi插件

```
grafana-cli plugins install gnocchixyz-gnocchi-datasource
```

### 14.6.6 登录grafana配置数据源

默认登录密码是admin/admin，第一次登录需要修改密码。
![title](/api/file/getImage?fileId=5c90a4843cd7c901f600001d)

![title](/api/file/getImage?fileId=5c90a57e3cd7c901f6000025)

如果配置keystone认证则HTTP URL配置keystone的地址，并且配置Access为Server,验证成功后会从keystone中去找gnocchi的URL地址并返回。配置如下：
![title](/api/file/getImage?fileId=5c90a5ae3cd7c901f6000026)

配置完成后，点击“Save & Test”，配置成功则提示“Data source is working”

![title](/api/file/getImage?fileId=5c90a7c23cd7c901f6000027)

### 14.6.7 配置dashboard

在grafana官网上下载一个dashboard的模板，如：https://grafana.com/dashboards/4569

在grafana界面导入，并选择数据源为上述配置的数据源

![title](/api/file/getImage?fileId=5c90ac383cd7c901f6000028)

```
