mongodb - 更改数据目录后无法启动 MongoDB

Question

我已在以下链接的帮助下安装:https://www.digitalocean.com/community/tutorials/how-to-install-mongodb-on-ubuntu-16-04

默认情况下工作正常。但是当我更改/etc/mongod.conf 中的数据目录时

#From
dbPath: /var/lib/mongodb
#To
dbPath: /media/user/'Mounted Volume'/mongodb_data

我无法启动 MongoDB。以下是错误信息

我是 MongoDB 新手。也许我错过了一些非常简单的东西。

来自MongoDB config file documentation page

The Linux package init scripts included in the official MongoDB packages depend on specific values for systemLog.path, storage.dbpath, and processManagement.fork. If you modify these settings in the default configuration file, mongod may not start.

因此，如果您在配置文件中修改这些属性，您很可能必须编写一个新的初始化脚本。
