Sonotype Nexus 存储库/OrientDB 无法连接到数据库

【问题标题】：Sonotype Nexus Repository/OrientDB can't connect to databaseSonotype Nexus 存储库/OrientDB 无法连接到数据库
【发布时间】：2019-01-17 11:35:05
【问题描述】：

昨天，由于磁盘已满事件，我们的 nexus 存储库实例横向运行。释放一些空间并尝试重新启动后，无法再访问 nexus。结果，数据库损坏（可能）并且无法连接。当我运行 nexus-orient-console.jar 进行连接时，我得到的是：

orientdb> CONNECT plocal:/nexus-data/db/component admin admin

因为我什至无法连接到数据库，所以我无法尝试此处建议的恢复步骤 > OrientDB corruption state in Nexus Repository version 3.2.0-01。 有什么方法可以修复和恢复数据库，还是我们只是 S.O.L.？ 有什么方法可以在忽略数据库问题的安全模式下启动 nexus？

【问题讨论】：

  • 您可以尝试按照建议修复数据库。
  • @Lance Held 您找到解决方案了吗？我也遇到了同样的问题。
  • @rayitopy 我们最终通过升级到最新版本的 nexus 破解了它。它在大多数情况下都有效，但应用程序的某些方面仍然无法正常工作。我们已经跛行了几个月，已经到了我们决定安装一个新实例并将我们的设置转录为 repos 的地步。 :-/

【解决方案1】：

这个帖子必须解决我们的问题。 https://groups.google.com/a/glists.sonatype.com/g/nexus-users/c/64W_y9fDGzQ/m/o0FKRgiDAwAJ?pli=1

总而言之，这个步骤修复了我的错误（和你一样）：

rm /mnt/sonatype-work/nexus3/db/config/*.wal

然后尝试启动控制台并修复数据库

在 orientdb 提示符下运行以下命令：

connect plocal:/mnt/sonatype-work/nexus3/db/confg admin admin
repair database --fix-links
rebuild index *
disconnect 
exit

对于 Nexus 3.2.1+，可以使用included OrientDB client。

【讨论】：

  • 这里只需删除 *.wal 文件并重新启动 Nexus (3.34.0) 就足够了。 Nexus 开始自行重建索引。
