mongodb - 从 14.10 升级到 Ubuntu 15.04 会破坏 mongo - 如何修复？

Question

我昨天犯了升级到 15.04 的错误 :-)。现在我的 mongod 无法启动:

MongoDB shell version: 2.6.9
connecting to: test
2015-04-26T08:45:08.339-0600 warning: Failed to connect to 127.0.0.1:27017, reason: errno:111 Connection refused
2015-04-26T08:45:08.339-0600 Error: couldn't connect to server 127.0.0.1:27017 (127.0.0.1), connection attempt failed at src/mongo/shell/mongo.js:146
exception: connect failed

sudo 服务 mongod 状态

● mongod.service
   Loaded: not-found (Reason: No such file or directory)
   Active: inactive (dead)

所以接下来，我搜索了mongodb相关的锁文件，将其删除。- 没有帮助。所以接下来我做了:

sudo -u mongodb mongod --repair --dbpath /var/lib/mongodb/
sudo service mongodb start

 sudo -u mongodb mongod --repair --dbpath /var/lib/mongodb/

仍然没有帮助。所以接下来我创建了一个/data/db 目录，希望这可能会起作用——不行......那么有什么想法吗？我认为这与摆脱 Upstart 有关？

谢谢...

Answer 1

对于遇到这种情况的其他人 - 多么痛苦!原来 Mongo>2.6.3 的 start 有一个已知问题:Support Systemd (cannot start mongodb with init scripts with Fedora 15 or above)如此处所述:https://jira.mongodb.org/browse/SERVER-17742除非有强烈的抗议，否则似乎直到 Ubuntu 16.04 才能完全修复 >2.6.3。

所以我的解决方案是发出:

sudo apt-get install --reinstall mongodb

这恢复到 mongo 2.6.3，现在一切正常!对于那些遇到这种情况的人...感谢所有看过这篇文章的人!
