第六步，Eucalyptus镜像管理
1.我们需要根据上一节，source 下载的 'eucarc' 文件
完成后我们就可以使用 euca2tool 的命令了,如 euca-describe-images 等。此时我们运行此命令后结果为空,因为我们还没有上传并注册任何的镜像文件。

2.下载现成的操作系统镜像文件

这里我们选择下载centos5.3
euca-centos-5.3-x86_64.tar.gz

3.添加镜像
i.kernel

mkdir -p /data/centOS/v53/xen
euca-bundle-image -d /data1/centOS/v53/xen -i ./euca-centos-5.3-x86_64/xen-kernel/vmlinuz-2.6.27.21-0.1-xen --kernel true

mkdir -p /data/centOS/v53/xen euca-bundle-image -d /data1/centOS/v53/xen -i ./euca-centos-5.3-x86_64/xen-kernel/vmlinuz-2.6.27.21-0.1-xen --kernel true

euca-upload-bundle -b centOS-5.3-xen-again-buckit -m /data/centOS/v53/xen/vmlinuz-2.6.27.21-0.1-xen.manifest.xml

euca-upload-bundle -b centOS-5.3-xen-again-buckit -m /data/centOS/v53/xen/vmlinuz-2.6.27.21-0.1-xen.manifest.xml
成功以后，命令行输出

EMI=emi-AF6E179A

EMI=emi-AF6E179A

备注：其中$EKI 为注册的 kernel ID,$ERI 为注册的 ramdisk ID,$EMI 为注册的 img ID

4.查看镜像
a.上传成功后,我们在 web 界面上就可以看到镜像文件了:



b.前端ncs运行
执行euca-describe-images 命令,会显示如下内容
IMAGE eri-E15A17DF centOS-5.3-xen-again-buckit/initrd-2.6.27.21-0.1-xen.manifest.xml admin available public x86_64 ramdisk instance-store

4.删除镜像
a.必须首先删除镜像

euca-deregister

euca-deregister
b.删除储存在bucket的文件

euca-delete-bundle -a $EC2_ACCESS_KEY -s $EC2_SECRET_KEY --url $S3_URL -b  -p

euca-delete-bundle -a $EC2_ACCESS_KEY -s $EC2_SECRET_KEY --url $S3_URL -b -p
如果想删除image 和 bucket，添加'--clear'参数

euca-delete-bundle -a $EC2_ACCESS_KEY -s $EC2_SECRET_KEY --url $S3_URL -b  -p  --clear
