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:
* Method: system
* Database at: /var/lib/rally/database
* Configuration file at: /etc/rally
======================================================================
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
[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
}
}
}
]
}
[root@rally nova]# . /root/rally/.venv/bin/activate
[root@rally nova]# rally -v task start boot.json(/root/rally/doc/samples/tasks/scenarios/nova这是当前的目录)
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 } } } } ] } |
