启动2秒后，蒙戈坠毁

Question

我的mongod服务在启动后2到5秒内崩溃.我不明白为什么。

下面是systemctl日志：

systemctl状态mongod.service

mongod.service - High-performance, schema-free document-oriented database

到目前为止，我已经：

• 检查权限(一切看起来都很好)
• 检查服务
• 尝试删除mongo.lock

mongod似乎启动时没有任何错误，但几秒钟后就失败了。

有什么想法吗？

Answer 1

搜索mongod.lock并删除它并重新启动服务。

1. 查找Mongo数据路径cat /etc/mongod.conf | grep dbPath
2. 在其中查找mongod.lock文件。
3. 如果在那里，那么删除文件并重新启动服务器。
