Question

在这里寻求帮助！

我将Jenkins（v2.134）作为由Rancher（v1.6.16）管理的Docker容器运行;我正在使用haproxy（HA-Proxy版本1.6.3 2015/12/25）作为我的负载均衡器。 Jenkins JNLP端口配置为50000。haproxy获得了TCP端口转发的规则（8081> 50000）

我的奴隶（macmini）在不同的网络中并且在防火墙后面（该网络可以访问我的Jenkins Infra）。我正在使用“通过隧道连接”属性和指定的端口“：8081”。端口8081已在防火墙中打开。

我的Jenkins Java版本是-

openjdk version "1.8.0_151"
OpenJDK Runtime Environment (build 1.8.0_151-8u151-b12-1~deb9u1-b12)

我的从Java版本是-

Sun JDK "1.8.0_151"

以下是座席日志-

任何帮助将不胜感激。

有没有办法获取更多详细的日志？

我发现了问题；这是我的负载均衡器（haproxy）的TCP连接默认超时（如果没有流量）为50000ms。 https://cbonte.github.io/haproxy-dconv/configuration-1.5.html

然而，詹金斯到奴隶的ping间隔，即hudson.slaves.ChannelPinger.pingInterval为5分钟（错误）。 https://wiki.jenkins.io/display/JENKINS/Features+controlled+by+system+properties

增加负载均衡器超时，即> 5分钟即可解决此问题。

詹金斯奴隶JNLP连接被终止
