【博文推薦】如何進行 OpenStack 的性能測試及平臺功能性測試
作者：wang1511766618
社區對OpenStack平臺功能性的測試工具采用Tempest，性能測試采用Rally。本篇博文對Rally、Tempest是什么；如何安裝Rally、Tempest的詳細過程進行介紹。下面就讓我們一起學習。

一、OpenStack Rally 性能測試
1.注意點
在測試nova，在配置文件里面如果不指定網絡id，那么默認是外網的網絡（該網絡是共享的），如果想要指定網絡，那么該網絡必須是共享的狀態，否則將會報錯：無法發現網絡。如果測試多于50臺的虛擬機需要修改默認值，因為默認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 |
- +-------------------------+---------+
修改默認值可以在界面，管理員->默認值，進行修改；其次可以在運行nova-api服務的節點上修改配置文件nova.conf
#p#
2.安裝rally：
- [root@rally nova]#git clone https://github.com/stackforge/rally.git
- [root@rally rally]# /usr/bin/easy_install pip （安裝pip,有就不需要裝了）
- [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]
- [root@rally nova]#pip install -U virtualenv 安裝虛擬環境（可裝可不裝，一般為了系統的干凈還是裝個虛擬環境）
- [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
- ....
======================================================================
Information about your Rally installation:
* Method: system
* Database at: /var/lib/rally/database
* Configuration file at: /etc/rally
======================================================================
安裝完成，數據庫的配置這里暫時沒做。
創建一個隨便命名的.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#
如此便可繼續往下進行OpenStack基準測試了。
舉個測試啟動虛擬機的例子：boot.json文件內容如下：
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"}],(默認是沒有這行的)
- },
- "runner": {
- "type": "constant",
- "times": 100, （測試次數100） "concurrency": 2 （并發數）
- },
- "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。

社區對OpenStack平臺功能性的測試工具采用Tempest，性能測試采用Rally。
二、OpenStack平臺功能性的測試工具Tempest
1、什么是Tempest
1）.Tempest
- api # API的測試集
- cli # OpenStack的命令行工具測試集
- common # 一些公共的工具類和函數
- scenario # 對OpenStack的常用場景進行測試，包括基本的啟動VM，掛載volumn和網絡配置等
- services # tempest自己實現的OpenStack API Client，自己實現是為了不讓一些bug隱藏在官方實現的Client里面。
- stress # 壓力測試集，利用multiprocessing來啟動多個進程來同時對OpenStack發起請求。
- thirdparty # EC2兼容的API測試集
- whitebox # 白盒測試集，主要是對DB操作，然后發起請求，然后比對結果
2）.tempest是通過nose驅動的，python語言編寫，使用testtools和testresources等幾個測試工具庫
3）.tempest.test.BaseTestCase,BaseTestCase聲明config屬性,讀取配置文件
4）.tempest.test.TestCase聲明很多工具函數，供調用
5）.每個測試可以分別測試JSON格式和XML格式
#p#
2.安裝Tempest
下載源碼
- git clone https:
查看python版本
- python --version
如若是2.6執行如下，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）
如果沒有執行安裝命令
- [root@controller001 ~]#yum install libxslt-devel
檢查是否有gcc環境，沒有則安裝
- [root@controller001 ~]#yum install gcc-c++
安裝一些相關的包
- [root@controller001 ~]#yum install libevent-devel openssl-devel libffi-devel python-devel
- [root@controller001 ~]#/usr/bin/easy_install pip
進入tempest目錄進行安裝（沒有安裝虛擬機環境）
- [root@controller001 ~]#python setup.py install
(可選)如果不想將tempest安裝在真實環境中那么執行如下命令
- [root@controller001 ~]#pip -U virtualenv
- [root@controller001 ~]#virtualenv .venv
- [root@controller001 ~]#. .venv/bin/activate
- [root@controller001 ~]#python setup.py install
安裝junitxml，是測試報告輸出為xml格式
- [root@controller001]#pip install junitxml
由于tempest在Icehouse時期上使用是有bug的，bug如下：
在/root/tempest/tempest/openstack/common/log.py文件下添加
注意：在Juno版本時期，此bug已修復，故而可以跳過。
修改tempest.conf文件,注意創建外網的時候不要共享，否則在測試啟動虛擬機以及進行網絡測試的時候會報錯
- cp etc/tempest.conf.sample etc/tempest.conf
- [root@controller001 etc]# == /usr/bincatalog_type===53f6877e-2f46-43e3-93b7-7e22786cacb2

- region =RegionOne
- tenant_network_cidr = 10.100.0.0/16
- tenant_network_mask_bits = 28
- tenant_networks_reachable = true
- [network-feature-enabled]
- [object-storage]
- [object-storage-feature-enabled]
- [orchestration]
- [scenario]
- [service_available] （這里配置需要測試哪些模塊）
- ceilometer = false
- cinder = true
- glance = true
- heat = false
- horizon = true
- ironic = false
- neutron = true
- nova = true
- sahara = false

- trove = false
- zaqar = false
- [stress]
- [telemetry]
- [volume]
- [volume-feature-enabled]
- multi_backend =true (測試cinder的后端存儲有多個backend)
修改好配置文件之后，進行測試（以測試keystone當中token為例）
- [root@controller001 tempest]# nosetests tempest/api/identity/admin/test_tokens.py --with-xunit --xunit-file=/root/keystone_test_tokens.xml
----------------------------------------------------------------------
