我在官方 ELB 文档中找到了这个

默认情况下，负载均衡器将每个请求独立路由到负载最小的应用程序实例。

但是Newvem上的一篇文章说ELB只支持Round Robin算法

Amazon ELB 支持的算法- 目前，Amazon ELB 仅支持循环 (RR) 和会话粘性算法。

那么是哪一个呢？

我正在尝试在 VPS 上部署 octopress，但收到此错误bundle: not found但已安装捆绑包！

完全错误。

我做了谷歌并发现了cap shell然后我发现PATH变量可能不是以某种方式设置的

$ cap shell                                                                                                                                                         1 ↵

但是当我在 [email protected] 上 ssh

deploy@mydomain:~$ id

deploy@mydomain:~$ echo $PATH

我不确定我到底错过了什么。我也尝试添加source /etc/profile.d/rvm.sh ，.bash_login但仍然没有运气。

all默认情况下，如何在所有节点中包含此类？

我的 manifests/nodes.pp 中的片段

class all {

  case $operatingsystem {
    debian, ubuntu: {
      include hosts
      include ssh
    }
    default: {
      err("OS NOT supported")
    }
  }
}

node default {
  include all
}

node 'dobby' {
  include all ## << 
  include apache
  include logrotate
}
