Openstack : 6、Centos7下搭建带有Ceilometer的devstack（mitaka版本）

环境：vmware10  , CentOS-7-x86_64-Minimal-1611.iso

目标：搭建带有ceilometer的devstack，devstack版本为mitaka

步骤：

1 参考这篇博客

：http://www.chenshake.com/openstack-project-series-3-devstack/

这篇博客虽然是在ubuntu14.04环境下搭建devstack，但是修改一小部分内容后可以在centos7上搭建成功。

2 在这篇博客的基础上，需要在执行./stack.sh之前：添加豆瓣源

sudo mkdir -p /opt/stack/.pip sudo vim /opt/stack/.pip/pip.conf sudo mkdir -p /root/.pip sudo vim /root/.pip/pip.conf 在上述两个pip.conf中配置以下内容 [global] timeout = 6000 index-url = http://pypi.douban.com/simple trusted-host = pypi.douban.com

3安装centos7 rpm包

作用是：安装centos7对应rpm包，使得后续安装过程中不会因为rpm找不到对应的东西而安装失败。

rpm -ivh http://dl.fedoraproject.org/pub/epel/7/x86_64/e/epel-release-7-9.noarch.rpm

 

4 配置好local.conf文件

附上local.conf文件

注意：

1 修改

HOST_IP=192.168.192.130

将上述192.168.192.130修改为你的ip地址

2 修改

FLOATING_RANGE="192.168.192.0/24"

FIXED_RANGE="10.0.0.0/24"

Q_FLOATING_ALLOCATION_POOL=start=192.168.192.82,end=192.168.192.90

PUBLIC_NETWORK_GATEWAY="192.168.192.2"

将上述

自己主机对应的ip地址是192.168.192.130,所以对应网络是:

192.168.192

用你自己的网络该替换上述192.168.192即可

 

5 遇到的问题

问题1 ： 执行./stack.sh报错Failed building wheel for libvirt-python

原因: libvirt-python1.3.2版本太低

解决办法：参考http://www.itdadao.com/articles/c15a1275477p0.html

1 sudo vim /opt/stack/requirements/upper-constraints.txt 的文件的175行中读取的。 libvirt-python===1.3.2 修改为 libvirt-python===2.0.0   2 sudo vim /opt/stack/requirements/global-requirements.txt libvirt-python >=2.0.0   3 local.conf RECLONE=True 改为 RECLONE=False   4 将/opt/stack/requirements/upper-constraints.txt和/opt/stack/requirements/global-requirements.txt 中的openstack版本 openstacksdk===0.8.1 修改为 openstacksdk===0.9.11

 

问题2：安装成功无法打开dashboard页面

原因：centos开启防火墙

解决办法：执行如下命令。centos下不能访问dashboard,需要关闭防火墙，并且是在stack用户下。

su stack systemctl stop firewalld.service #停止firewall systemctl disable firewalld.service #禁止firewall开机启动 firewall-cmd --state #查看默认防火墙状态（关闭后显示notrunning，开启后显示running） systemctl status firewalld.service service iptables stop
