OrientDB“移动现有数据库时出错”
OrientDB " Error on moving existent database"
我正在尝试使用 docker 设置 OrientDB 分布式配置。但是我在启动第二个节点时遇到错误 -

如果我在没有 docker 的情况下启动 orientdb 集群，则不会出现此错误。
我也可以将它移动到容器中
[root@64f6cc1eba61 orientdb]# mv -v /orientdb/databases/testDB
/orientdb/databases/../backup/databases/testDB
'/orientdb/databases/testDB' ->
'/orientdb/databases/../backup/databases/testDB'
'/orientdb/databases/testDB/distributed-config.json' ->
'/orientdb/databases/../backup/databases/testDB/distributed-config.json'
removed '/orientdb/databases/testDB/distributed-config.json' removed
directory: '/orientdb/databases/testDB' [root@64f6cc1eba61 orientdb]#
ls -l /orientdb/databases/../backup/databases/testDB total 4
-rw-r--r--. 1 root root 455 Oct 9 11:32 distributed-config.json [root@64f6cc1eba61 orientdb]#
我使用的是 OrientDB 2.1.3 版
已报告并修复此问题：
https://github.com/orientechnologies/orientdb/issues/4891
将 'distributed.backupDirectory' 变量设置为特定目录，问题应该就消失了。
顺便说一句，运行 orient 分布在 docker 是我们目前无法使用的经验：
- Docker 尚不支持多播，您可以解决它，但这很痛苦。但主要问题是：
- Docker 不会在重启时重复使用 ip 地址，因此容器重启会给它一个新的 ip 地址，这会把你的集群搞得一团糟。
我们放弃使用 orient distributed with docker 直到 docker 解决了这两个问题（我相信这两个问题都在路线图上）。
如果您有其他经历，我很高兴听到您的想法。
