Question

我是新的nexus oss（3.2.0），在安装和访问nexus后我可以看到Log中的一些错误，看起来nexus和外界之间存在连接问题。

日志如下

如果是的话，我们有什么方法可以为代理商提供联系服务吗？有人可以指导我我可以看到一些组件状态显示为在线远程连接挂起。

Answer 1

在系统----> HTTP 下有一个选项可以为出站连接添加代理。有了它，它工作得很好。

Answer 2

信息日志消息是因为您的计算机未连接到外部世界。这不是警告或错误，也不会影响您的表现。

您看到的屏幕截图字符串是由于NXRM3系统中的消息混淆（以及与NXRM2的偏差）以及NXRM3当前未设计为在调用之前与远程代理联系的事实。此偏差在此处描述：https://issues.sonatype.org/browse/NEXUS-9878

这些存储库实际上已准备好连接。如果它们失败了（例如，如果你尝试使用它们并且你的计算机没有连接到外部世界），就会有这样的信息。一旦你连接它们（例如从它们接收组件），它们将变为＆＃34;在线 - 远程可用＆＃34;。

在NXRM3的下一个版本中，消息将从＆＃34;在线 - 远程连接待定......＆＃34;到＆＃34;在线 - 准备连接＆＃34;帮助减轻这种混乱。这里的公共票：https://issues.sonatype.org/browse/NEXUS-11001
