Nexus 启动速度非常慢

问题描述 投票：0回答：1

我们在 Odroid C1+ 上运行 Sonatype Nexus 3，大约相当于 RPi 2。是的，不推荐，但对于我们 2 的开发团队来说，性能是可以接受的。

启动时除外。 Nexus 3 OSS 服务器需要一个小时或更长时间才能可用。

这正常吗？ 知道为什么这么慢吗？

以下是一家初创公司的一些日志条目。

一些注意事项：

  • 这太酷了！我们内部团队的某人不久前在 Raspberry Pi 3 上运行了它，所以我们喜欢看到这样的东西
  • 我们不支持此配置，因此我们提供的任何帮助都有点“哇，这太酷了”之类的水平

我们的内部人员表示，他注意到 NXRM 3 在 Raspberry Pi 3 上启动期间更新模式时内存不足，并且他尚未找到解决方法。

他找到了一个解决方法。他还留着大胡子。他编辑了 nexus.vmoptions 以具有以下内容：


-Xms256M
-Xmx256M
-XX:MaxDirectMemorySize=512M

Orient 使用系统内存，这与使用 Java 堆的 Nexus Repo 不同（如果这对您有帮助的话）。上面关于定向和关闭的注释可能也非常相关。

以下是我们整理的一些有关 Orient 和内存以及调优的信息：

优化OrientDB数据库内存

这里还有一篇关于 Nexus Repository Manager 3 系统要求的更通用的文章：

Nexus Repository Manager 3 系统要求

我对你的团队的建议截然不同，可以使用我们的 Docker 镜像，并在你必须使用的任何硬件上运行 Nexus Repo。

Docker Nexus3

祝你好运！
