为何我在单机部署使用的时候，过几分钟来分钟就断掉

在ubuntu1804部署了nebula和NebulaGraph Studio，在浏览器中连接以后，可以操作几分钟，过几分钟连接就断掉？

你的问题选的分类不对，我给你编辑成【用户问答】了。你看下 Studio 相关的配置是什么，贴一下。

原因是nebula graph会自己挂掉，为啥会挂掉我不太清楚。我重启下nebula就可以了，这个我该从哪里排查，我看logs中有诸多文件

5

可以在日志里看看meta和storage的错误日志，默认路径为：/usr/local/nebula/logs/。

请忽略时间，我刚安的ubuntu 使用的是美国时区的时间，所以log是20号的

所有设置都是默认设置，我没有做任何修改

真是过10来分钟就断掉，重启服务就恢复，我也是醉了 :innocent: :innocent:

刚打开就挂掉，呜呜呜呜

11

用这个关掉所有nebula服务再重启
pgrep -al -u$(whoami) nebula- | cut -d ' ' -f 1 | xargs kill -9 {}
再检查一下是不是内存不够？

12

没用的，这些我试过了，我把机器重启都没用，把所有进程杀死，内存我设成8G，还是会挂掉，可能是某个地方需要设置下，现在就是找不着问题在哪

Add Hosts 了吗？

14

添加了，而且我用这个命令
./nebula-console -addr 127.0.0.1 -port 9669 -u root -p qsh123 -f /home/qsh/Downloads/basketballplayer-2.X.ngql

导入数据，也是会报错

https://docs.nebula-graph.io/2.0/basketballplayer-2.X.ngql

15

但是综合你的日志和截图，看上去都是没有成功将 storaged 加入集群。通过 show hosts 看下

16

好像是这个原因，不过为啥是offline状态

没有 add hosts 就是 offline 状态

Drop一下hosts再重新加？

端口不应该是 9779 吗？你修改过端口？
