[root@controller ~]# yum install openstack-dashboard -y
[root@controller ~]# vi /etc/openstack-dashboard/local_settings
直接覆盖我给的local_settings文件也行（为了减少出错，大家还是用我提供的local_settings文件替换覆盖）

八．创建双机相互信任
1.controller服务器
[root@controller ~]# ssh-keygen -t rsa
Generating public/private rsa key pair.
Enter file in which to save the key (/root/.ssh/id_rsa):
Created directory '/root/.ssh'.
Enter passphrase (empty for no passphrase):
Enter same passphrase again:
Your identification has been saved in /root/.ssh/id_rsa.
Your public key has been saved in /root/.ssh/id_rsa.pub.
The key fingerprint is:
43:5e:57:44:68:d3:b2:89:57:39:a1:fd:43:c7:41:e4 root@controller
The key's randomart image is:
+--[ RSA 2048]----+
 =B*
=+*..
. .oo*.Eo
o ...+ ...
S . ..

2.compute服务器
[root@compute ~]# ssh-keygen -t rsa
Generating public/private rsa key pair.
Enter file in which to save the key (/root/.ssh/id_rsa):
Created directory '/root/.ssh'.
Enter passphrase (empty for no passphrase):
Enter same passphrase again:
Your identification has been saved in /root/.ssh/id_rsa.
Your public key has been saved in /root/.ssh/id_rsa.pub.
The key fingerprint is:
9d:f1:44:85:79:ab:94:b7:1e:53:51:f5:f8:63:05:70 root@compute
The key's randomart image is:
