云迁移/云灾备必备的调研工具

目录

项目说明

prophet是一个用于云迁移与云灾备前期技术调研使用的工具,目前主要对源端主机的基本情况进行采集,通过技术指标的比对,确保被调研的源端主机能够正确被HyperMotion/HyperBDR工具正确迁移或灾备。该项目目前已经在多个实际的云迁移和云灾备项目中得到验证,可以放心使用。

该项目未来发展的愿景是提供一站式调研平台,包括但不限于如下资源:各种云平台资源使用状况、文件存储、对象存储、容器平台、大数据平台、中间件、数据库等。同时也将提供蓝图画板,方便在项目前期进行方案编写使用,降低云迁移与云灾备过于冗长的前期调研周期。

目前prophet主要有以下功能组成:

  • 通过nmap指令扫描全网存活的主机,并尽量通过包信息分析主机的基本情况
  • (稳定)通过VMWare API接口采集主机的详细信息,包含计算、存储和网络等与主机迁移
  • (测试)通过Ansible获取Linux主机的详细信息,包含计算、存储和网络等与主机相关信息
  • (测试)通过Windows WMI接口采集Windows主机的详细信息,包含计算、存储和网络等与主机相关信息
  • (稳定)将采集后的结果以yaml格式进行打包和压缩,并进行脱敏处理(移除用户相关信息)
  • (稳定)对采集后的结果进行分析,得出最终的技术调研结论

安装说明

代码安装

git clone https://github.com/Cloud-Discovery/prophet

cd prophet
virtualenv venv
source venv/bin/activate

pip install -r requirements.txt
pip install .

容器方式

目前该项目每次提交后都会自动进行构建并推送到国内容器源中,可以直接使用

docker pull registry.cn-beijing.aliyuncs.com/oneprocloud-opensource/cloud-discovery-prophet:latest

使用说明

基本使用流程

  1. 扫描指定的IP地址段
  2. 在扫描结果的csv中,填写需要获取详情的主机鉴权信息
  3. 批量采集
  4. 分析, 得到结果

(稳定)功能一:扫描全网运行的实例

功能说明

通过网络扫描发现某一网段内存活的主机,并进行记录,可以作为后续更详细信息采集的输入。扫描完成后,将自动在指定路径下生成scan_hosts.csv文件,用于存储信息。

***** 注意:为了防止对生产环境造成较大压力,扫描时采用单进程方式,所以扫描进度较慢,经过测算扫描一个子网掩码为24的子网所需要30分钟左右的时间。**

usage: prophet-collect scan [-h] --host HOST [--arg ARG] --output-path
                            OUTPUT_PATH

optional arguments:
  -h, --help            show this help message and exit
  --host HOST           Input host, example: 192.168.10.0/24, 192.168.10.1-2
  --arg ARG             Arguments for nmap, for more detailed, please check
                        nmap document
  --output-path OUTPUT_PATH
                        Generate initial host report path

示例一: 获取子网主机

扫描192.168.10.0/24所有存活主机信息,并将csv文件生成在/tmp目录中。

prophet-collect scan --host 192.168.10.0/24 --output-path /tmp/

示例二: 获取指定IP网段主机

扫描192.168.10.2-192.168.10.50所有存活主机信息,并将csv文件生成在/tmp目录中。

prophet-collect scan --host 192.168.10.2-50 --output-path /tmp/

csv结构说明

字段名称 字段说明
hostname 主机名,可以为空
ip 用户IP地址,必须
username 用户名,如果为VMware,则为ESXi或者vCenter的用户名
password 密码,如果为VMware,则为ESXi或者vCenter的用户名
ssh_port Linux,该字段为ssh端口VMware ESXi或vCenter则为连接端口,默认为443Windows则默认为空
key_path 如果为密钥登陆,需要指定密钥的绝对路径,否则为空
mac 主机MAC地址,可以为空
vendor 生产厂商,可以为空,如果是VMware运行的虚拟机则为VMware
check_status 是否需要采集详细信息, 如果需要则设置为check,否则工具将自动跳过
os 操作系统类型,目前支持的类型为:Linux/Windows/VMware,大小写敏感
version 操作系统的版本,可以为空
tcp_ports 对外开放的端口,可以为空
do_status 详细信息采集状态,表示是否完成采集或者失败,默认为空

参考样例

(稳定)功能二:详细信息采集

功能说明

用户在模板填入鉴权信息后,进行进一步详细扫描。

注意:

  • 如果是VMware的虚拟机,则只会通过所在的ESXi主机进行扫描
  • 如果是Windows主机,需要Administrator用户进行扫描
  • 采集主机如果成功,则再次运行脚本时不会再进行采集,除非用户指定force-check参数
  • 采集失败的主机在下一次采集时,会重新采集
  • 最终生产的压缩包,一切与用户鉴权相关的敏感信息都已经被移除
  • (稳定)目前VMware采集部分是稳定的
  • (测试)目前Linux和Windows采集部分仍然是测试版本
usage: prophet-collect collect [-h] --host-file HOST_FILE --output-path
                               OUTPUT_PATH [-f]

optional arguments:
  -h, --help            show this help message and exit
  --host-file HOST_FILE
                        Host file which generated by network scan
  --output-path OUTPUT_PATH
                        Output path for batch collection
  -f, --force-check     Force check all hosts

示例:执行采集

首先需要在生成的scan_csv.csv中更新要采集主机的鉴权信息。

prophet-collect collect --host-file /tmp/scan_hosts.csv --output-path /tmp -f

采集结果说明

采集目录结构

host_collection_info
|-- linux_hosts -> Linux主机采集信息
|-- vmware_hosts -> VMWare主机采集信息
`-- windows_hosts -> Windows主机采集信息
|-- mac_info.yaml -> 所有主机根据Mac地址进行索引,便于后续分析
|-- prophet.log -> 采集过程中的日志,便于对于未知场景分析
|-- scan_hosts.csv -> 采集的主机文件,含开放端口信息

另外在输出目录中会生成host_collection_info_xxxxxxx.zip文件,该文件为最终用于分析的压缩文件。

(稳定)功能三: 分析并输出报告

功能说明

将采集后的结果进行分析,并输出最终的可迁移性报告,该部分可以根据需求扩展。

usage: prophet-analysis report [-h] --package-file PACKAGE_FILE --output-path
                               OUTPUT_PATH [--clean]

optional arguments:
  -h, --help            show this help message and exit
  --package-file PACKAGE_FILE
                        Investigate package file which is genreated by
                        prophet-collect
  --output-path OUTPUT_PATH
                        Generate report path
  --clean               Generate report path

示例:分析并输出报告

prophet-analysis -d -v report --package-file /tmp/host_collection_info_20211215202459.zip --output-path /tmp
