- 报错日志说明的很详细，
Nexus使用的OrientDB的其中一个库component已经变成了read only只读模式，修复数据库需要将该库导出后再导入。
停止nexus进程
备份准备修复的数据库
注意出错的库名，出错的库不一定是component，具体看出错日志（Nexus的OrientDB有多个库）。
1
| cp -rv /data/sonatype-work/nexus3/db/component /data/component.bak
|
到Nexus安装目录下/lib/support下，运行nexus-orient-console.jar
1
| cd /data/nexus3/lib/support
|
启动console
1
| java -jar nexus-orient-console.jar
|
如果Nexus库已经很大，在执行后面的导出操作时可能会报heap OOM错误，可以在启动时调大内存
1
| java -jar -Xms4g -Xmx4g nexus-orient-console.jar
|
连接出错的数据库，执行导出、备份、删除、重建、导入
重要：以下操作有删除动作，注意一定要先做好备份
连接出错的数据库(注意出错的库不见得与笔者一致，注意查看出错日志)
1
| orientdb> connect PLOCAL:/data/sonatype-work/nexus3/db/component admin admin
|
导出
1
| orientdb {db=component}> EXPORT DATABASE /data/orientdb-component.export
|
关闭连接
1
| orientdb {db=component}> DISCONNECT
|
删除出问题的库
1
| orientdb> DROP DATABASE PLOCAL:/data/sonatype-work/nexus3/db/component admin admin
|
重新创建出问题的库
1
| orientdb> CREATE DATABASE PLOCAL:/data/sonatype-work/nexus3/db/component admin admin
|
导入
1
| orientdb {db=component}> IMPORT DATABASE /data/orientdb-component.export.gz
|
关闭连接
1
| orientdb {db=component}> DISCONNECT
|
退出控制台
启动nexus进程
