Rhel 7.2 install Openstack with RDO

REF:
1. RDO封装的很好了。细节看不到,但是准备环境比较烦。 我这个Rhel 7.2 安装了两个 group.  禁用Selinux.  禁用NetworkManager,改用network.然后重启安装依赖包。

Server with GUI
Development Tools

systemctl disable NetworkManager
systemctl stop NetworkManager
systemctl enable network
sed -i 's/SELINUX=.*/SELINUX=disabled/' /etc/selinux/config

2. EPEL 我已经提前安装了,记录下碰到的问题.
下面的包都需要装，有些是EPEL的包，而且我这个机器装了pyenv,pip ,多个版本的python,ruby的包管理gem.

pyenv  versions
  system
* 3.4.3 (set by /root/.python-version)

yum install libselinux-ruby
yum install PyPAM python-ldap python-memcached python-zope-interface mod_wsgi python-suds scipy  python-cheetah python-rtslib sysfsutils targetcli
yum install libvirt-python python-werkzeug net-snmp python-libguestfs libvirt-daemon-config-nwfilter  keepalived ipset python-webtest dnsmasq-utils libxslt-python
yum install memcached xinetd
yum install graphviz  perl-DBI perl-DBD-MySQL MySQL-python

其中python-werkzeug 需要从rpmfind 下载一个CentOS7.2 用的包。 

wget ftp://rpmfind.net/linux/centos/7.2.1511/extras/x86_64/Packages/python-werkzeug-0.9.1-2.el7.noarch.rpm
rpm -i python-werkzeug-0.9.1-2.el7.noarch.rpm

卸载的有：

rpm -e wxGTK-2.8.12-20.el7.x86_64 --nodeps
rpm -e  mediainfo-gui-0.7.82-1.el7.x86_64
rpm -e wxBase-2.8.12-20.el7.x86_64
pip uninstall requests

安装命令：

packstack --allinone --default-password=pass

完成就可以用admin/pass 登陆dashboard.
另外生成了两个rc文件，是为了访问不同的tenant(project）

4 -rw------- 1 root root         225 Mar 15 21:41 keystonerc_admin
4 -rw------- 1 root root         225 Mar 15 21:41 keystonerc_demo

source 一下，即可使用openstack命令去query.

source keystonerc_admin
openstack user list

关闭服务后，要手动启动rabbitmq-server,我发现neutron的log里面报了大量的AQMP -Server无法连接的错。

ERROR oslo.messaging._drivers.impl_rabbit [-] AMQP server on XX.XX.XX.XX:5672 is unreachable: [Errno 111] ECONNREFUSED. Trying again in 2 seconds

openstack-service stop
systemctl start rabbitmq-server
openstack-service start
