一、OpenStack Rally 性能测试
1.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
#p#
2.安装rally：
- [root@rally nova]#git clone https://github.com/stackforge/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]
- [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：
- [root@rally rally]# : :
- [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 |
- +------------+-----------+-----------+
#p#
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。

社区对OpenStack平台功能性的测试工具采用Tempest，性能测试采用Rally。
二、OpenStack平台功能性的测试工具Tempest
1、什么是Tempest
1）.Tempest
- api # API的测试集
- cli # OpenStack的命令行工具测试集
- common # 一些公共的工具类和函数
- scenario # 对OpenStack的常用场景进行测试，包括基本的启动VM，挂载volumn和网络配置等
- services # tempest自己实现的OpenStack API Client，自己实现是为了不让一些bug隐藏在官方实现的Client里面。
- stress # 压力测试集，利用multiprocessing来启动多个进程来同时对OpenStack发起请求。
- thirdparty # EC2兼容的API测试集
- whitebox # 白盒测试集，主要是对DB操作，然后发起请求，然后比对结果
2）.tempest是通过nose驱动的，python语言编写，使用testtools和testresources等几个测试工具库
3）.tempest.test.BaseTestCase,BaseTestCase声明config属性,读取配置文件
4）.tempest.test.TestCase声明很多工具函数，供调用
5）.每个测试可以分别测试JSON格式和XML格式
#p#
2.安装Tempest
下载源码
- git clone https:
查看python版本
- python --version
如若是2.6执行如下，2.7不需要
- wget https://pypi.python.org/packages/source/u/unittest2/unittest2-0.5.1.tar.gztar zxvf unittest2-0.5.1.tar.gz
- cd unittest2-0.5.1python setup.py install
查看xslt-config命令是否存在
- [root@controller001 ~]# whereis xslt-config
- xslt-config: /usr/bin/xslt-config（代表存在）
如果没有执行安装命令
- [root@controller001 ~]#yum install libxslt-devel
检查是否有gcc环境，没有则安装
- [root@controller001 ~]#yum install gcc-c++
安装一些相关的包
- [root@controller001 ~]#yum install libevent-devel openssl-devel libffi-devel python-devel
- [root@controller001 ~]#/usr/bin/easy_install pip
进入tempest目录进行安装（没有安装虚拟机环境）
- [root@controller001 ~]#python setup.py install
(可选)如果不想将tempest安装在真实环境中那么执行如下命令
- [root@controller001 ~]#pip -U virtualenv
- [root@controller001 ~]#virtualenv .venv
- [root@controller001 ~]#. .venv/bin/activate
- [root@controller001 ~]#python setup.py install
安装junitxml，是测试报告输出为xml格式
- [root@controller001]#pip install junitxml
由于tempest在Icehouse时期上使用是有bug的，bug如下：
在/root/tempest/tempest/openstack/common/log.py文件下添加
注意：在Juno版本时期，此bug已修复，故而可以跳过。
修改tempest.conf文件,注意创建外网的时候不要共享，否则在测试启动虚拟机以及进行网络测试的时候会报错
- cp etc/tempest.conf.sample etc/tempest.conf
- [root@controller001 etc]# == /usr/bincatalog_type===53f6877e-2f46-43e3-93b7-7e22786cacb2

- [object-storage-feature-enabled]

- trove = false
- zaqar = false
- [stress]
- [telemetry]
- [volume]
- [volume-feature-enabled]
- multi_backend =true (测试cinder的后端存储有多个backend)
修改好配置文件之后，进行测试（以测试keystone当中token为例）
- [root@controller001 tempest]# nosetests tempest/api/identity/admin/test_tokens.py --with-xunit --xunit-file=/root/keystone_test_tokens.xml
----------------------------------------------------------------------
