Jenkins CLI连接被拒绝 [英] Jenkins CLI connection refused

问题描述

执行时

java -jar jenkins-cli.jar -s https://jenkins_url help

由于某种原因，我的连接被拒绝. Jenkins版本是1580.3，用户具有Jenkins服务器的权限，cli jar是最新的，并且ssh公钥已正确配置.知道是什么原因造成的吗?这是堆栈跟踪是否有帮助:

I'm getting connection refused for some reason. Jenkins version is 1580.3, user has the permissions on Jenkins server, cli jar is up-to-date and ssh public key is configured properly. Any idea what might be causing this? Here's the stack trace if it will help:

推荐答案

如果连接被拒绝，则可能禁用了CLI，但是很可能存在防火墙或网络问题.

If the connection is refused, perhaps the CLI is disabled, but more likely there's a firewall or network issue.

对Jenkins的每个成功的HTTP请求都将CLI端口作为HTTP标头进行响应，因此您可以快速检查它是否已启用:

Each successful HTTP request to Jenkins responds with the CLI port as an HTTP header, so you can quickly check whether it's enabled:

curl -sI http://jenkins/ | grep CLI

或者，如记录在Wiki ，您可以检查是否已启用TCP端口.在 http://jenkins/configureSecurity/

Alternatively, as documented on the wiki, you can check whether the TCP port is enabled. Look for "TCP port for JNLP slave agents" at http://jenkins/configureSecurity/

但是，由于您的堆栈跟踪表明CLI客户端正在尝试建立与特定端口的连接，因此它建议启用CLI，并且Jenkins在其HTTP响应中公布该端口号.

However, since your stacktrace indicates that the CLI client is trying to establish a connection to a particular port, it suggests that the CLI is enabled, and Jenkins is advertising that port number in its HTTP responses.

因此，您可以尝试手动连接到该端口，以检查其是否打开:

So you could try to connect to that port manually, to check whether it's open:

telnet jenkins <cli-port>

如果在此还看到拒绝连接"，则说明您的Jenkins和CLI客户端设置似乎可以，但是存在网络问题.在这种情况下，请检查Jenkins服务器上的防火墙是否允许该CLI端口上的传入连接.

If you also see "Connection refused" here, then you know that your Jenkins and CLI client setup seem to be ok, but you have a network issue. In which case, check that the firewall on the Jenkins server allows incoming connections on that CLI port.

要简化防火墙配置，可以在上述配置安全性"页面中从随机端口切换到固定端口.

To make firewall configuration easier, you can switch from a random port to a fixed port in the "configure security" page mentioned above.
