第一个问题：

如何自学：

1.apt-get install -y ubuntu-cloud-keyring

的含义

man apt-get

第二个问题

> 是定向输出到文件，如果文件不存在，就创建文件；如果文件存在，就将其清空

；一般我们备份清理日志文件的时候，就是这种方法：先备份日志，再用`>`，将日志

文件清空（文件大小变成0字节）；

这个是将输出内容追加到目标文件中。如果文件不存在，就创建文件；如果文件存在

，则将新的内容追加到那个文件的末尾，该文件中的原有内容不受影响。

第三个问题：

echo的作用是什么？

Linux教程：Linux中的echo命令简介

安装nova过程中产生错误

cd /etc/init.d/; for i in $( ls nova-* ); do sudo service $i restart; done

sudo: unable to resolve host controller1

第四个问题：

sqlalchemy.exc.OperationalError: (OperationalError) (1049, "Unknown database 'keystone'") None None

数据库同步的位置不正确，应该在Linux中执行这条命令

mysql> keystone-manage db_sync;

ERROR 1064 (42000): You have an error in your SQL syntax; check the manual that corresponds to your MySQL server version for the right syntax to use near 'keystone-manage db_sync' at line 1

创建数据需要注意的问题：

create datebase keystone;

ERROR 1064 (42000): You have an error in your SQL syntax; check the manual that corresponds to your MySQL server version for the right syntax to use near 'datebase keystone' at line 1

mysql> CREATE DATABASE keystone;

Query OK, 1 row affected (0.00 sec)

记录：

> 是定向输出到文件，如果文件不存在，就创建文件；如果文件存在，就将其清空；一般我们备份清理日志文件的时候，就是这种方法：先备份日志，再用`>`，将日志文件清空（文件大小变成0字节）；

这个是将输出内容追加到目标文件中。如果文件不存在，就创建文件；如果文件存在，则将新的内容追加到那个文件的末尾，该文件中的原有内容不受影响。

第五个问题

echo的作用是什么？

打印

第六个问题

1.什么是flavoer定义内存，磁盘空间等

遇到问题：

keystone-manage db_sync;

ERROR 1064 (42000): You have an error in your SQL syntax; check the manual that corresponds to your MySQL server version for the right syntax to use near 'keystone-manage db_sync' at line 1

检查自己的网络是否连接

第七个问题

ERROR: You must provide a username via either --os_username or env[OS_USERNAME]

如何解决。

这个问题，其实还是你的环境变量导致的。

export OS_TENANT_NAME=admin

export OS_USERNAME=admin

export OS_PASSWORD=hastexo

export OS_AUTH_URL="http://localhost:5000/v2.0/"

export EC2_URL=$(keystone catalog --service ec2 | awk '/ publicURL / { print $4 }')

export CREDS=$(keystone ec2-credentials-create)

export EC2_ACCESS_KEY=$(echo "$CREDS" | awk '/ access / { print $4 }')
