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。

  • 使用ssh部署代码是错误的。正确做法是先进入 ibmcloud target --cf 使用 ibmcloud cf push命令
    • 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。
