openstack控制器安装手工安装monasca

admin

monasca的所有组件都可以安装在一个节点上，例如openstack控制器节点上，也可以将其部署在多节点上。本文中，将在我的openstack集群中创建的新VM中安装monasca-api，该VM具有关联的浮动ip。Monasca-agent已安装在控制器节点上。代理节点通过浮动ip将指标发布到api节点。它们在同一子网中。

• 安装我们需要的软件包和工具
  2 D5 F  T( Y4 J" H/ rapt-get install -y git
  apt-get install openjdk-7-jre-headless python-pip python-dev
• 安装mysql数据库 如果您在openstack控制器节点中安装了monasca-api，则可以跳过安装，将已安装的msyql用于openstack服务。
  . G: }" }/ Y$ b) B# q4 p' Tapt-get install -y mysql-server
  创建monasca数据库架构，在此处下载mon.sql（ https://raw.githubusercontent.com/stackforge/cookbook-monasca-schema/master/files/default/mysql/mon.sql）
  mysql -uroot -ppassword < mon_mysql.sql
• 安装Zookeeper 安装Zookeeper并重新启动它。我使用本地主机接口，并且只有一个Zookeeper，因此默认配置文件不需要配置。
  

  apt-get install -y zookeeper zookeeperd zookeeper-bin  service zookeeper restart

8 ^5 k8 C! V* q, n" b; W6 T. ^DevStack安装

运行Monasca DevStack至少需要一台具有10GB RAM的主机。

可在此处找到安装和运行Devstack的说明：

https://docs.openstack.org/devstack/latest/
+ V6 T, y9 P3 Y# M- G

要在DevStack中运行Monasca，请执行以下三个步骤。

• 克隆DevStack代码库。
  . V6 L' d  _$ a* N/ t

git clone https://git.openstack.org/openstack-dev/devstack

• 将以下内容添加到devstack目录根目录中的DevStack local.conf文件中。如果local.conf不存在，则可能需要创建它。
  

# BEGIN DEVSTACK LOCAL.CONF CONTENTS​[[local|localrc]]DATABASE_PASSWORD=secretdatabaseRABBIT_PASSWORD=secretrabbitADMIN_PASSWORD=secretadminSERVICE_PASSWORD=secretserviceSERVICE_TOKEN=111222333444​LOGFILE=$DEST/logs/stack.sh.logLOGDIR=$DEST/logsLOG_COLOR=False​# The following two variables allow switching between Java and Python for the implementations# of the Monasca API and the Monasca Persister. If these variables are not set, then the# default is to install the Python implementations of both the Monasca API and the Monasca Persister.​# Uncomment one of the following two lines to choose Java or Python for the Monasca API.MONASCA_API_IMPLEMENTATION_LANG=${MONASCA_API_IMPLEMENTATION_LANG:-java}# MONASCA_API_IMPLEMENTATION_LANG=${MONASCA_API_IMPLEMENTATION_LANG:-python}​# Uncomment of the following two lines to choose Java or Python for the Monasca Pesister.MONASCA_PERSISTER_IMPLEMENTATION_LANG=${MONASCA_PERSISTER_IMPLEMENTATION_LANG:-java}# MONASCA_PERSISTER_IMPLEMENTATION_LANG=${MONASCA_PERSISTER_IMPLEMENTATION_LANG:-python}​# Uncomment one of the following two lines to choose either InfluxDB or Vertica.# default "influxdb" is selected as metric DBMONASCA_METRICS_DB=${MONASCA_METRICS_DB:-influxdb}# MONASCA_METRICS_DB=${MONASCA_METRICS_DB:-vertica}​# This line will enable all of Monasca.enable_plugin monasca-api https://git.openstack.org/openstack/monasca-api​# END DEVSTACK LOCAL.CONF CONTENTS

• 从devstack目录的根目录运行“ ./stack.sh”。
  ; K5 ~! O: M( s! R1 ], w

如果要使用最少的OpenStack组件运行Monasca，可以将以下两行添加到local.conf文件中。

disable_all_servicesenable_service rabbit mysql key
% h0 I- O, d, P/ w

如果您还希望安装Tempest测试，请添加 tempest

enable_service rabbit mysql key tempest

要启用Horizon和Monasca UI，请添加 horizon

enable_service rabbit mysql key horizon tempest
. l* k$ Q" t* z3 u使用Vagrant

Vagrant可用于使用Vagrantfile部署运行有Devstack和Monasca的VM。安装Vagrant后，只需在../monasca-api/devstack目录中运行vagrant up命令。

要在devstack安装中使用本地代码库，请将更改提交到本地存储库的master分支，然后在配置文件中修改与要使用的本地存储库相对应的变量file://my/local/repo/location。要使用monasca-api repo的本地实例，请将更改enable_plugin monasca-api https://git.openstack.org/openstack/monasca-api为enable_plugin monasca-api file://my/repo/is/here。这两个设置仅在重建devstack VM时生效。

• 使用Vagrant将Vertica启用为Metrics DB
  Monasca支持同时使用InfluxDB和Vertica来存储指标和告警状态历史记录。默认情况下，在DevStack环境中启用InfluxDB。
  Vertica是Hewlett Packard Enterprise的商业数据库。可以下载免费的Community Edition（CE）安装程序，要启用Vertica，请执行以下操作：
  

• 注册并下载Vertica Debian安装程序https://my.vertica.com/download/vertica/community-edition/，并将其放在您的主目录中。不幸的是，DevStack安装程序没有可以自动使用的URL，因此必须单独下载该URL，并将其放置在安装程序运行时可以找到它的位置。安装程序假定此位置是您的主目录。使用Vagrant时，您的主目录通常将以“ /vagrant_home”挂载在VM内。
• 修改local.conf中MONASCA_METRICS_DB变量，配置Vertica的支持，如下所示：
  ; q$ ^. U/ g3 _2 n2 ]9 M! SMONASCA_METRICS_DB=${MONASCA_METRICS_DB:-vertica}

• 使用ORM支持
  ORM支持可以通过MONASCA_DATABASE_USE_ORM变量来控制。但是，如果启用了PostgreSQL（也称为数据库后端），则将强制提供ORM支持

• 使用WSGI
  Monasca-api可以使用uwsgi和gunicorn与Apache一起部署。默认情况下，monasca-api在uwsgi下运行。如果您想使用Gunicorn，请确保其中devstack/local.conf包含：

使用Monasca Dashboard

安装完成Monasca Dashboard Plugin后，可以通过web控制台进行查看以及管理相应的监控与告警。

在操作控制台的“Monitoring”栏，单击“Launch Monitoring Dashboard“，这将打开在管理节点上运行的专用OpenStack Horizon门户。

在该面板中，您可以：

• 单击OpenStack服务名称，以查看服务告警。
• 单击服务器名称以查看相关设备的告警。

监控信息存储在两个数据库中（Vertica/influxdb与mysql）。备份监控数据时，将同时备份两个数据库。看到

• 监控指标在Vertica中存储7天。
• 配置设置存储在MySQL中。
• 如果监控节点上的服务在高负载（例如15个控制网络和200个计算节点）下停止，则消息队列将在大约6个小时内开始清除。
