opensack-mitaka网络性能测试shaker

一、项目介绍

Shaker项目是由Mirantis发起，专门针对OpenStack网络性能的测试工具。通过模拟不同的网络场景和heat模板，创建虚拟机，并在虚拟机里运行iperf、iperf3、netperf等工具来对网络进行自动化性能测试，并且把测试的结果以网页的形式输出。

目前OpenStack的另外一个著名测试工具Rally, 也是由Mirantis发起，可以针对OpenStack进行整体测试，也可以对OpenStack的功能，存储的性能进行压力测试，以及测试磁盘的IOPS，并提供很好的Web展示。

Rally与Shaker各自的侧重点，两个工具结合起来，在OpenStack交付给用户的场景下，可以提供一份相对客观的验收报告。

二、环境说明

需要有一个可用的OpenStack环境，并配置好Heat服务，因为Shaker需要使用编排服务来启动各种场景下的虚拟机，本文环境如下：

controller/shaker	172.20.5.15/24
compute01	172.20.5.16/24
compute02	172.20.5.17/24

三、安装配置

1、openstack安装配置

1、基础配置

使用本次安装教程，会安装ceilometer+gnocchi集成、heat、FWAAS、VPNAAS、LBAASv1等

# 所有节点全部执行
mkdir /etc/yum.repos.d/bak
mv /etc/yum.repos.d/*repo /etc/yum.repos.d/bak
cat >>  /etc/yum.repos.d/openstack-mitaka.repo << EOF
[base]
name=CentOS-$releasever - Base
baseurl=http://172.20.2.44/base 

enabled=1
gpgcheck=0

[mitaka]
name=mitaka
baseurl=http://172.20.2.44/openstack-mitaka 

enabled=1
gpgcheck=0

[epel]
name=epel
baseurl=http://172.20.2.44/epel 

enabled=1
gpgcheck=0
EOF

yum install python-cheetah python-gnocchi python-nova libvirt libvirt-devel libvirt-client -y
2、安装配置openstack环境

# 控制节点执行
yum install -y openstack-packstack
packstack --gen-answer-file=openstack.txt
/usr/bin/sleep 5


# 这里第一行修改compute节点对应的IP地址，这里测试compute节点IP地址是172.20.5.16,172.20.5.17，IP地址之间用逗号(,)隔开
sed -i 
-e 's@CONFIG_COMPUTE_HOSTS=.*@CONFIG_COMPUTE_HOSTS=172.20.5.16,172.20.5.17@g' 
-e 's@CONFIG_CEILOMETER_METERING_BACKEND=.*@CONFIG_CEILOMETER_METERING_BACKEND=gnocchi@g' 
-e 's@CONFIG_NAGIOS_INSTALL=.*@CONFIG_NAGIOS_INSTALL=n@g' 
-e 's@CONFIG_SWIFT_INSTALL=.*@CONFIG_SWIFT_INSTALL=n@g' 
-e 's@CONFIG_HEAT_INSTALL=.*@CONFIG_HEAT_INSTALL=y@g' 
-e 's@CONFIG_HEAT_CLOUDWATCH_INSTALL=.*@CONFIG_HEAT_CLOUDWATCH_INSTALL=y@g' 
-e 's@CONFIG_HEAT_CFN_INSTALL=.*@CONFIG_HEAT_CFN_INSTALL=y@g' 
-e 's@CONFIG_NEUTRON_FWAAS=.*@CONFIG_NEUTRON_FWAAS=y@g' 
-e 's@CONFIG_NEUTRON_VPNAAS=.*@CONFIG_NEUTRON_VPNAAS=y@g' 
-e 's@CONFIG_LBAAS_INSTALL=.*@CONFIG_LBAAS_INSTALL=y@g' 
-e 's@CONFIG_MARIADB_PW=.*@CONFIG_MARIADB_PW=root1234@g' 
-e 's@CONFIG_KEYSTONE_ADMIN_PW=.*@CONFIG_KEYSTONE_ADMIN_PW=admin@g' 
-e 's@CONFIG_KEYSTONE_API_VERSION=.*@CONFIG_KEYSTONE_API_VERSION=v3@g' openstack.txt
3、安装前后配置

# 控制节点执行
packstack --answer-file=openstack.txt

# 安装过程会修改yum源。这里需要执行如下指令，修改过来
sed -i 's@enabled=.*@enabled=1@g' /etc/yum.repos.d/openstack-mitaka.repo 

# 漫长的等待之后，如果不报错，进行下面操作

sed -i 
-e 's@type_drivers =.*@type_drivers = flat,vxlan@g' 
-e 's@#flat_networks =.*@flat_networks = *@g' /etc/neutron/plugins/ml2/ml2_conf.ini 


# 对接gnocchi后期配置
openstack-config --set /etc/ceilometer/ceilometer.conf  DEFAULT event_dispatchers gnocchi
openstack-config --set /etc/ceilometer/ceilometer.conf  api gnocchi_is_enabled  true
openstack-config --set /etc/ceilometer/ceilometer.conf  dispatcher_gnocchi filter_project  services
openstack-config --set /etc/ceilometer/ceilometer.conf  dispatcher_gnocchi archive_policy  low
openstack-config --set /etc/ceilometer/ceilometer.conf  dispatcher_gnocchi resources_definition_file  gnocchi_resources.yaml

openstack-service restart ceilometer




# 在计算节点1上执行ssh互信
sed -i 
-e 's@nova.*@nova:x:162:162:OpenStack Nova Daemons:/var/lib/nova:/bin/bash@g' /etc/passwd

echo nova | passwd --stdin nova

su - nova

# 在计算节点2上执行ssh互信
sed -i 
-e 's@nova.*@nova:x:162:162:OpenStack Nova Daemons:/var/lib/nova:/bin/bash@g' /etc/passwd

# 修改成自己的计算节点IP地址


echo nova | passwd --stdin nova

su - nova



# 修改成自己的计算节点IP地址
ssh-keygen  -t rsa -f ~/.ssh/id_rsa  -P ''

ssh-copy-id  -i .ssh/id_rsa.pub nova@172.20.5.17

ssh-keygen  -t rsa -f ~/.ssh/id_rsa  -P ''

ssh-copy-id  -i .ssh/id_rsa.pub nova@172.20.5.16
4、在控制节点上配置NFS共享存储

# 在公司openstack上创建一个cinder卷，挂载到controller节点上，作为共享存储盘使用。如果只是作为测试建议100G可用

# 分区，格式化

# 分区
fdisk /dev/vdc <<EOF
n
p
1


w
EOF

# 格式化
mkfs.xfs /dev/vdc1

# 挂载
mount /dev/vdc1 /opt/nova/instances/

# NFS共享
yum -y install nfs-utils rpcbind -y

mkdir -p /opt/nova/instances
echo "/opt/nova/instances 172.20.0.0/16(rw,no_root_squash,no_all_squash,sync)" > /etc/exports
exportfs -r
chmod -R 777 /opt/nova/instances/
systemctl enable rpcbind.service
systemctl start rpcbind.service
systemctl enable nfs-server.service 
systemctl start nfs-server.service
5、2个计算节点使用NFS

showmount -e 172.20.5.15
mount -t nfs 172.20.5.15:/opt/nova/instances /var/lib/nova/instances/
chown -R nova.nova /var/lib/nova

2、shaker安装配置

yum install git gcc-c++ python-devel
git clone http://git.trystack.cn/openstack/shaker
cd shaker
pip install .

cd ..
source keystonerc_admin



export ELEMENTS_PATH=shaker/shaker/resources/image_elements
disk-image-create -o shaker-image.qcow2 centos vm shaker
