注意点 ：在测试 nova，在配置文件里面如果不指定网络 id，那么默认是外网的网络（该网络是共享的），如果想要指定网络，那么该网络必须是共享的状态，否则将会报错：无法发现网络。如果测试多于 50 台的虚拟机需要修改默认值，因为默认值是有限制的可用如下命令查看：
| [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 | | |
| +-------------------------+---------+ |
修改默认值可以在界面，管理员 -> 默认值，进行修改；其次可以在运行 nova-api 服务的节点上修改配置文件 nova.conf
安装 rally：
[root@rally nova]#git clone https://github.com/openstack/rally.git
[root@rally rally]# /usr/bin/easy_install pip（安装 pip, 有就不需要装了）
[root@rally rally]# mkdir /root/.pip[root@rally rally]# vim /root/.pip/pip.conf（设置 pip 源，加快安装速度）[global]index-url=http://pypi.douban.com/simple
[root@rally nova]#pip install -U virtualenv 安装虚拟环境（可装可不装，一般为了系统的干净还是装个虚拟环境）
[root@rally nova]#virtualenv .venv
[root@rally nova]#. .venv/bin/activate
[root@rally nova]#yum install gcc-c++（安装编译工具）
[root@rally nova]#cd rally
[root@rally rally]#./install_rally.sh....
======================================================================
Information about your Rally installation:

======================================================================
安装完成，数据库的配置这里暂时没做。
创建一个随便命名的.json 格式文件：
| 这是 keystone 版本为 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 版本为 v3 时用以下模板参考 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” }
}
[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-c0f435f1ae54
[root@rally rally]# rally deployment check
keystone endpoints are valid and following services are available:
+————+———–+———–+
| services | type | status |
+————+———–+———–+
| ceilometer | metering | Available |
| cinder | volume | Available |
| cinderv2 | volumev2 | Available |
| glance | image | Available |
| keystone | identity | Available |
| neutron | network | Available |
| nova | compute | Available |
| nova_ec2 | ec2 | Available |
| novav3 | computev3 | Available |
+————+———–+———–+
如此便可继续往下进行 OpenStack 基准测试了。
举个测试启动虚拟机的例子 ：boot.json 文件内容如下：
doc/samples/tasks/scenarios/nova/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"}],(默认是没有这行的) | |
| }, | |
| "runner": {"type": "constant", | |
| "times": 100,（测试次数 100）"concurrency": 2（并发数） | |
| }, | |
| "context": {"users": {"tenants": 3, | |
| "users_per_tenant": 2 | |
| } | |
| } | |
| } | |
| ] | |
| } |
| [] | |
| [] |
以上的图是测试结果。
当通过 rally deployment check 检查 OpenStack 的 service 状态时，出现__unknown__, 这是由于 keystone 的 service catalog 没有返回 service name 并且 rally 无法通过 type 识别 service，但此时可以利用 rally plugin show api_version，来指定相应的 api 版本，举个例子：
| # 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 | |
| } | |
| } | |
| } | |
| } | |
| ] | |
| } |
