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。但是当我在/etc/mongod.conf中更改数据目录时

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

我无法启动MongoDB。以下是错误消息

$mongo

以下是状态

我是MongoDB的新手。也许我错过了很简单的事情。

Answer 1

来自MongoDB config file documentation page

官方MongoDB软件包中包含的Linux软件包init脚本取决于systemLog.path， storage.dbpath和processManagement.fork的特定值。如果您在默认配置文件中修改这些设置，则mongod可能无法启动。

因此，如果在配置文件中修改这些属性，则很可能必须编写新的init脚本。
