openstack搭建云主机出现错误，如何解决？(操作系统-linux)

问题遇到的现象和发生背景

搭建openstack(先电版)
执行iaas-install-neutron-controller.sh
iaas-install-neutron-controller-gre.sh
iaas-install-neutron-compute.sh
iaas-install-neutron-compute-gre.sh报错

问题相关代码，请勿粘贴截图

[root@computer bin]# iaas-install-neutron-compute.sh

运行结果及报错内容

错误：软件包：libxslt-python-1.1.28-5.el7.x86_64 (iaas)
需要：libxslt = 1.1.28-5.el7
已安装: libxslt-1.1.28-6.el7.x86_64 (@anaconda)
libxslt = 1.1.28-6.el7
可用: libxslt-1.1.28-5.el7.x86_64 (iaas)
libxslt = 1.1.28-5.el7
您可以尝试添加 --skip-broken 选项来解决该问题
您可以尝试执行：rpm -Va --nofiles --nodigest

我的解答思路和尝试过的方法

卸载libxslt-1.1.28-6.el7.x86_64
安装libxslt-1.1.28-5.el7.x86_64

我想要达到的结果

安装脚本不报错 网页创建网络可以显示

已解决

卸载 libxslt-1.1.28-6.el7.x86_64
安装 libxslt-1.1.28-5.el7.x86_64
问题解决

#上述安装出错的原因是软件包的版本问题libxslt-1.1.28-6.el7.x86_64，先卸载，再安装低1.1.28-5版本，即可正常安装了
[root@controller ~]# rpm  -q  libxslt-1.1.28-6.el7.x86_64      
[root@controller ~]# yum  erase  libxslt-1.1.28-6.el7.x86_64      
[root@controller ~]# yum  install  libxslt-1.1.28-5.el7.x86_64      
[root@controller ~]# iaas-install-neutron-controller.sh
我今天也出现了同样样的问题，用这个方法解决的

你把报错复制到记事本发给我

openstack 拒绝访问了

安装云主机状态总是error，孵化都等了5分钟，然后报错error，孵化过程都有ip分配，失败就没有ip，失败
