计算节点安装openstack-nova-compute找不到包

按照官方文档的要求进行的安装，出现这个问题

[root@compute1 yum.repos.d]# yum install openstack-nova-compute
Loaded plugins: fastestmirror, langpacks
Repository base is listed more than once in the configuration
Repository updates is listed more than once in the configuration
Repository extras is listed more than once in the configuration
Repository centosplus is listed more than once in the configuration
Loading mirror speeds from cached hostfile
 * base: mirrors.aliyun.com
 * extras: mirrors.aliyun.com
 * updates: mirrors.aliyun.com
No package openstack-nova-compute available.
Error: Nothing to do

解决办法：
先安装centos-release-openstack-pike，这个包应该是先决条件，其他节点安装也遇到同样问题，官方文档没有看到,后安装openstack-nova-compute

yum install centos-release-openstack-pike.x86_64
yum update
yum install openstack-nova-compute

openstack-nova-compute安装后服务起不来

解决办法：
编辑：/etc/httpd/conf.d/openstack-dashboard.conf
在WSGISocketPrefix run/wsgi下面加一行代码：
WSGIApplicationGroup %{GLOBAL}
保存，重启httpd服务。

总结

官方安装指导，变来变去，需要总结多个版本来发现问题。
修改配置一定要小心。
