无法打开本地存储 '/opt/sonatype-work/nexus3/db/config' with mode=rw

Question

我正在将我的 ubuntu 机器中的 nexus 升级到 3.22.0。为此，我遵循了本指南“https://help.sonatype.com/repomanager3/installation/run-as-a-service”。 Nexus 在本地与 nexus 用户一起运行，但是当我检查 ui 时出现 502 错误网关错误并且在日志中我发现了这一点。请帮忙解决这个问题。

Answer 1

就我而言，遵循的教程没有提到 ./sonatype-work/ 上的文件夹是 nexus 应用程序之外的文件夹，然后导致与权限相关的问题。我保留了

/opt/nexus/bin/nexus.vmoptions

原样，加上../sonatype-work/[注意2点]，然后重启整个机器，然后权限问题就解决了。

PS：我用 nexus 用户开始了第一次运行，并花了将近 1 小时在 8 核 12gb ram 机器上设置环境。数据库相关的东西，花了太多时间，但有效！

2 PS：使用此文件作为可能对您有帮助的 nexus.vmoptions 的示例。
