如果你在packstack启用 epel repo 的情况下进行安装，则需要卸载它和所有依赖项，然后在禁用 epel 后重新安装，以便正确安装所有正确版本的依赖项（来源）

运行以下命令：

yum autoremove epel-release  
yum autoremove openstack-packstack  
yum clean all  
yum install -y openstack-packstack

此错误表明 Nova 无法访问数据库，因为权限被拒绝。

This could happen if you changed anything in hostname or IP address
or database configuration so the access details stored currently no
longer matches the correct access details. 

To fix this issue do the following:
    Check the file **/usr/share/nova/nova-dist.conf**
    Check the line belongs to the database where it says:
    connection = 
    it should be something like 
    connection = mysql://nova:nova@localhost/nova
    Check the same line in the file
     **/etc/nova/nova.conf**  
    If the 2 files are different then update /usr/share/nova/nova-dist.conf with the same 
    connection string found in /etc/nova/nova.conf

如果这不起作用你需要执行以下操作：

    login to the mysql database with the root user and grant all privileges to the nova 
    and nova_api users and flush the privileges and restart mysql service and try again
