注意點：在測試nova，在配置文件裏面若是不指定網絡id，那麼默認是外網的網絡（該網絡是共享的），若是想要指定網絡，那麼該網絡必須是共享的狀態，不然將會報錯：沒法發現網絡。若是測試多於50臺的虛擬機須要修改默認值，由於默認值是有限制的可用以下命令查看：html

[root@rally nova]# nova absolute-limits   
+-------------------------+---------+
| Name                    | Value   |
+-------------------------+---------+
| maxServerMeta           | 128     |
| maxPersonality          | 100     |
| maxImageMeta            | 128     |
| maxPersonalitySize      | 10240   |
| maxTotalRAMSize         | 5120000 |
| maxSecurityGroupRules   | 20      |
| maxTotalKeypairs        | 100     |
| totalRAMUsed            | 58960   |
| maxSecurityGroups       | 10      |
| totalFloatingIpsUsed    | 0       |
| totalInstancesUsed      | 24      |
| totalSecurityGroupsUsed | 1       |
| maxTotalFloatingIps     | 10      |
| maxTotalInstances       | 200     |
| totalCoresUsed          | 51      |
| maxTotalCores           | 500     |
+-------------------------+---------+

修改默認值能夠在界面，管理員->默認值，進行修改；其次能夠在運行nova-api服務的節點上修改配置文件nova.confios

安裝rally：c++

[root@rally nova]#git clone https://github.com/openstack/rally.git

[root@rally rally]# /usr/bin/easy_install pip （安裝pip,有就不須要裝了）

[root@rally rally]# mkdir /root/.pip

[root@rally rally]# vim /root/.pip/pip.conf  （設置pip源，加快安裝速度）
[global]
index-url=http://pypi.douban.com/simple

[root@rally nova]#pip install -U virtualenv 安裝虛擬環境（可裝可不裝，通常爲了系統的乾淨仍是裝個虛擬環境）

[root@rally nova]#virtualenv .venv

[root@rally nova]#. .venv/bin/activate

[root@rally nova]#yum install gcc-c++      （安裝編譯工具）

[root@rally nova]#cd rally

[root@rally rally]#./install_rally.sh
....

安裝完成，數據庫的配置這裏暫時沒作。github

建立一個隨便命名的.json格式文件：數據庫

這是keystone版本爲v2
[root@rally rally]# cat existing.json
{
"type": "ExistingCloud",
"auth_url": 'http://172.16.105.189:35357/v2.0/',
"admin":{
    "username": admin,
    "password": admin,
    "tenant_name": admin
    }
}
keystone版本爲v3時用如下模板參考https://github.com/openstack/rally/blob/master/samples/deployments/existing-keystone-v3.json

[root@rally rally]# cat existing.json

{
"type": "ExistingCloud",
"auth_url": 'http://ip:5000/v3/',
"region_name": "RegionOne",
"endpoint_type": "public",
"admin":{
"username": "admin",
"password": "xxx",
"project_name": "admin",
"project_domain_name": "default",
"user_domain_name": "default"
}
}json

[root@rally rally]# rally deployment create --file=existing.json --name=existing
+--------------------------------------+----------------------------+----------+------------------+--------+
| uuid | created_at | name | status | active |
+--------------------------------------+----------------------------+----------+------------------+--------+
| 15ef811a-6460-407c-b391-c0f435f1ae54 | 2015-03-05 10:09:36.468176 | existing | deploy->finished | |
+--------------------------------------+----------------------------+----------+------------------+--------+
Using deployment: 15ef811a-6460-407c-b391-c0f435f1ae54vim

如此即可繼續往下進行OpenStack基準測試了。

舉個測試啓動虛擬機的例子：boot.json文件內容以下：網絡

doc/samples/tasks/scenarios/nova/boot.json

[root@rally nova]# cat boot.json 
{
    "NovaServers.boot_server": [
        {
            "args": {
                "flavor": {
                    "name": "m1.large"
                },
                "image": {
                    "name": "Windows_Server_2008R2_SP1_Standard_64bit"
                },
                "nics":[{"net-id": "c7048568-c966-4d57-a927-90dd8830fb96"}],(默認是沒有這行的)
            },
            "runner": {
                "type": "constant",
                "times": 100,                     （測試次數100）
                "concurrency": 2                 （併發數）
            },
            "context": {
                "users": {
                    "tenants": 3,                
                    "users_per_tenant": 2
                }
            }
        }
    ]
}

[root@rally nova]# . /root/rally/.venv/bin/activate
[root@rally nova]# rally -v task start boot.json（/root/rally/doc/samples/tasks/scenarios/nova這是當前的目錄）

以上的圖是測試結果。

當經過rally deployment check檢查OpenStack的service狀態時，出現__unknown__,這是因爲keystone 的service catalog沒有返回service name而且rally沒法經過type識別service，但此時能夠利用rally plugin show api_version，來指定相應的api版本，舉個例子：

        # In this example we will launch NovaKeypair.create_and_list_keypairs
        # scenario on 2.2 api version.
        {
            "NovaKeypair.create_and_list_keypairs": [
                {
                    "args": {
                        "key_type": "x509"
                    },
                    "runner": {
                        "type": "constant",
                        "times": 10,
                        "concurrency": 2
                    },
                    "context": {
                        "users": {
                            "tenants": 3,
                            "users_per_tenant": 2
                        },
                        "api_versions": {
                            "nova": {
                                "version": 2.2
                            }
                        }
                    }
                }
            ]
        }
