OpenStack云计算口袋书－第一章－开始OpenStack之旅（四）

四、配置管理客户端

1. 客户端环境说明

操作系统 Ubuntu12.04.2 64位

注意，客户端只需要是Linux，就可以正常操作，这里以Ubuntu 12.04.2为例。

操作用户：root和xiaoyuwang（sudoer用户）

2. 安装必要的openstack管理工具

root@localhost:~# sudo apt-get install euca2ools python-novaclient unzip

3. 创建必要的工作目录

xiaoyuwang@localhost:~$ cd
xiaoyuwang@localhost:~$ mkdir openstack
xiaoyuwang@localhost:~$ cd openstack
xiaoyuwang@localhost:~/openstack$

3. 远程复制nova.zip到本地xiaoyuwang目录下

xiaoyuwang@localhost:~/openstack$ scp [email protected]:nova.zip .
The authenticity of host '172.16.0.1 (172.16.0.1)' can't be established.
ECDSA key fingerprint is a0:dd:a1:68:aa:8b:22:7c:4b:17:54:70:5a:d5:78:f2.
Are you sure you want to continue connecting (yes/no)? yes
Warning: Permanently added '172.16.0.1' (ECDSA) to the list of known hosts.
[email protected]'s password:
Permission denied, please try again.
[email protected]'s password:
nova.zip 100% 5930 5.8KB/s 00:00
4. 解压nova.zip

xiaoyuwang@localhost:~/openstack$ unzip nova.zip
Archive: nova.zip
extracting: novarc
extracting: pk.pem
extracting: cert.pem
extracting: cacert.pem

5. 配置环境变量

xiaoyuwang@localhost:~/openstack$ . novarc
xiaoyuwang@localhost:~/openstack$

6. 配置访问虚拟机实例的密钥对

xiaoyuwang@localhost:~/openstack$ euca-add-keypair openstack > openstack.pem

设置文件的访问权限

xiaoyuwang@localhost:~/openstack$ chmod 0600 *.pem

文件内容如图：

我们也可以通过下面的命令来生成密钥对，这和上面的命令是一致的。

nova keypair-add openstack > openstack.pem
chmod 0600.pem
