云平台

• 虚拟化与云计算有什么区别？ (opens new window)

云服务器（VM，VIRTUAL MACHINE，IAAS）：是在一组集群物理服务器上虚拟出多个类似独立主机的部分，集群中每个主机上都有云主机的一个镜像， 从而大大提高了虚拟主机的安全稳定性。

虚拟专用服务器（VPS，VIRTUAL专用服务器，VDS）：采用虚拟软件，VZ或VM在一台物理服务器上虚拟出多个类似独立主机的部分， 能够实现单机多用户，每个部分都可以做单独的操作系统，管理方法同主机一样。

    • ibmcloud cf push 容器名 -b php_buildpack -m 256M -c "ls && ce /home"
  • 在push的代码目录里创建.bp-config配置文件，可以修改app的启动行为、可以修改php.ini等。否则你的container和其他服务做链接时就会被刷回原始状态。
  • 10天是指开发行为，必须是类似于ibm cloud cf restart或者cf push这样的行为，可以用纯shell脚本实现。

路由跟踪

• http://winmtr.net/download-winmtr (opens new window)
• Netcat详解 (opens new window)

在Linux中有一个更好的网络连通性判断工具，它可以结合ping | nslookup | tracert 来判断网络的相关特性，这个命令就是mtr。

注意：MTR使用的raw sockets是绕过TCP/IP协议，需要ROOT权限来执行，因此如果以普通用户身份来执行mtr会出错， 提示“mtr: unable to get raw sockets”

• tcpping- 禁止了ICMP协议（ping命令）也能用 (opens new window)
  • https://github.com/deajan/tcpping (opens new window)

tcpping脚本依赖tcptraceroute 组件，所以必须先安装yum install tcptraceroute

• https://elifulkerson.com/projects/ (opens new window)

注意tcpping与tcping 是不同的两款工具

• https://docs.microsoft.com/zh-cn/sysinternals/downloads/psping (opens new window)
• https://code.google.com/archive/p/paping/downloads (opens new window)

PsPing 是微软 PSTools 工具套件中的其中一个命令。除了 ICMP ping 测试，主要用来测试 TCP 端口的连通性， 还可以测试 TCP/UDP 网络时延和带宽。不过， PsPing 只能在 Windows 中运行。Linux 可以使用 PaPing （跨平台的开源工具）。

tracert

Tracert 列出分组经过的路由节点，以及它在IP 网络中每一跳的延迟（这里的延迟是指：分组从信息源发送到目的地所需的时间， 延迟也分为许多的种类——传播延迟、传输延迟、处理延迟、排队延迟等，是大多数网站性能的瓶颈之一）.

tracert [-d] [-h maximum_hops] [-j host-list] [-w timeout] [-R] [-S srcaddr] [-4] [-6] target_name

选项

• -d 指定不将 IP 地址解析到主机名称。
• -h maximum_hops 指定跃点数以跟踪到称为 target_name 的主机的路由。
• -j host-list 指定 Tracert 实用程序数据包所采用路径中的路由器接口列表。
• -w timeout 等待 timeout 为每次回复所指定的毫秒数。
• target_name 目标主机的名称或 IP 地址。
