Nimbus安装
类似亚马逊的EC2架构的IAAS云平台实现。
http://www.nimbus.com/
软件环境前提：
java 1.5以上
python 2.5以上，必须支持sqlite3：
$ python -c “import sqlite3” 不报错。
gcc
python-dev库和libssl-dev库。
apache ant 1.7以上。
随os的dhcp，可以：yum install dhcp
建立Nimbus需要的linux用户：
# groupadd nimbus
# useradd -m -d /home/nimbus -g nimbus -G root -s /bin/bash nimbus
# passwd nimbus
nimbus
# su – nimubs
$ vi ~/.bash_profile
export NIMBUS_HOME=/home/nimbus/nimbus-iaas-2.8
$ . ~/.bash_profile
安装Nimbus Services：
$ tar -zxvf nimbus-iaas-2.8-src.tar.gz
$ cd nimbus-iaas-2.8-src
$ ./install $NIMBUS_HOME
启动和停止：
$ cd $NIMBUS_HOME
$ ./bin/nimbus-iaas-2.8/bin/nimbus-version
Nimbus Version: 2.8
Documentation: http://www.nimbusproject.org/docs/2.8/admin/z2c/

$ ./bin/nimbusctl stop
$ ./bin/nimbusctl start
Launching Nimbus services… OK
Launching Cumulus services… OK
$ ps axf |grep nimbus

配置和启动DHCPD：
$ vi $NIMBUS_HOME/services/etc/nimbus/workspace-service/network-pools/public
…
# DNS server IP address (or ‘none’)
8.8.8.8
…
# hostname ipaddress gateway broadcast subnetmask [MAC]

}
注意：有些系统只能读取/etc/目录下的文件，不能读别的目录，这时候需要拷贝到/etc/下面。
# su – nimbus
$
查看Log：
$ vi $NIMBUS_HOME/var/cumulus.log
$ vi $NIMBUS_HOME/var/cumulus.log
建立Nimbus下的用户，跟上面的linux用户是没关系的：
$ mkdir $NIMBUS_HOME/home
$ ./bin/nimbus-list-users %
$ ./bin/nimbus-edit-user max.shu.cn@gmail.com
$ ./bin/nimbus-remove-user max.shu.cn@gmail.com
$ ./bin/nimbus-new-user -d $NIMBUS_HOME/home/maxshu max.shu.cn@gmail.com
cert : /home/nimbus/nimbus-iaas-2.8/home/maxshu/usercert.pem
key : /home/nimbus/nimbus-iaas-2.8/home/maxshu/userkey.pem
dn : /O=Auto/OU=NimbusCA/CN=max.shu.cn@gmail.com
canonical id : 901deb2a-14b8-11e1-831d-001e4f1bd705
access id : bIZXZO1ZMfubA5InmemVY
access secret : d4SpPDKQvyS18FEWO87ZJi4PB3BI8FomtkT0xYKXMM
url : None
web id : None
cloud properties : /home/nimbus/nimbus-iaas-2.8/home/maxshu/cloud.properties
安装客户端，这里假定跟services在同一台机器上，当然也可以不在同一台机器上：
$ tar -zxvf nimbus-cloud-client-020.tar.gz
$ cp $NIMBUS_HOME/home/maxshu/cloud.properties nimbus-cloud-client-020/conf/
$ cp $NIMBUS_HOME/var/ca/trusted-certs/* nimbus-cloud-client-020/lib/certs/
$ mkdir ~/.nimbus/
$ cp $NIMBUS_HOME/home/maxshu/*.pem ~/.nimbus/
$ cd nimbus-cloud-client-020
$ ./bin/cloud-client.sh –status
Querying for ALL instances.
There’s nothing running on this cloud that you own.
$ ./bin/cloud-client.sh –list
No files.
以上输出表示nimbus服务已经正常了。
客户端这里未完，待续。。。
