Linux服务器拒绝连接
Linux服务器拒绝连接
提问于 2018-01-31 09:29:13
当试图运行一个五旬节作业时，它失败了，它说：“打开连接到本地主机的用户名五旬节错误！”还有附加的评论：“五旬节用户名身份验证失败！”
所有的工作都是并行运行多个连接并执行一些Linux命令。由于一些奇怪的原因(我不知道)，这个工作在超过一定数量的连接(有些成功了，有些没有成功)之后就被杀了。
sshd_config主要具有默认设置，PasswordAuthentication设置为yes

虽然这并不是对您当前问题的直接回答，但是使用下面描述的方法可以防止您首先遇到这样的问题。
我认为在运行自动作业时使用私钥身份验证是一种更好的做法。
要做到这一点，您需要在您想要的每台机器上生成一个rsa ssh键，然后在运行命令的服务器(我们称之为管理服务器)中生成一个rsa ssh键，然后在管理服务器和ssh客户端机器之间交换密钥。
这将使您可以在不输入密码的情况下从管理服务器到ssh客户端服务器。
除了ssh密钥交换之外，我建议您检查我编写的这个剧本，它包装了"pssh“(并行-ssh)命令，并允许您提供命令--一个server.list文件和一个命令--脚本将在列表中的每个服务器上运行该命令，并为您提供一些关于在每个服务器上运行该命令的结果的有色指示。
此脚本的使用要求您安装pssh，这也可能被称为并行-ssh。
如果您不确定您应该采取哪些步骤，请告诉我，我将帮助您执行这些命令。
