Question

我已经在我的Ubuntu 10.04中安装了mongodb。

我知道当使用命令“ mongod ”启动mongodb服务器时，它需要/ data / db文件夹，并且可以通过创建“/ data / db /”轻松解决它”。另一种方法是使用mongod --dbpath“path”提供自己的路径，当我们打算为db提供自己的自定义路径时。

但是在浏览http://docs.mongodb.org/manual/tutorial/install-mongodb-on-ubuntu/链接时，我发现有一个配置文件。

我对它进行了以下更改。

＃mongodb.conf

dbpath=/EBS/Work/mongodb/data/db/


logpath=/EBS/Work/mongodb/mongodb.log

logappend=true

但是当我尝试使用“mongod”启动服务器时，它会抛出同样的错误即错误：dbpath（/ data / db /）不存在。我想知道如何永久地将我的dbpath重定向到我自己的自定义文件夹，因为每次你不想使用“mongod --dbpath path”键入路径。我们希望在配置文件中进行一些更改。

Answer 1

假设您已按照说明安装packaged version of MongoDB，则应使用mongod启动并停止service。

开始mongod：

 sudo service mongodb start

停止mongod：

 sudo service mongodb stop

如果使用service命令启动和停止，则应使用配置文件：/etc/mongodb.conf。

从命令行

开始mongod

如果您直接运行mongod而不是使用服务定义，则还需要将配置文件指定为command line parameter，如果您想要使用它：

mongod --config /etc/mongodb.conf

Answer 2

以下是我如何解决这个问题，只需遵循他们的官方文件即可。 HERE。

从teminal（运行ubuntu）一步一步：

cd into / srv folder =＆gt;＆gt; cd /srv/
make directory =＆gt;＆gt; mkdir -p mongodb
从/ srv /中为新创建的mongodb文件夹提供正确的权限和组......
最后，运行this =＆gt; mongod --dbpath /srv/mongodb/

“一步一步”终端的副本...... :)

Answer 3

更改新数据目录的用户：

chown mongodb [rute_directory]

并尝试另一次启动mongo服务

service mongodb start

我用这个解决了同样的问题。

Answer 4

从根系统文件夹中查找mongo日志文件

sudo find / -name“mongodb.log”-type f

结果： /var/log/mongodb/mongodb.log

打开/var/log/mongodb/mongodb.log
搜索最后一个“例外”字
尝试纠正异常

在我的情况下，例外是下一个： 2015-07-30T15：09：15.806 + 0300 initAndListen中的[initandlisten]异常：当日志/文件存在时，13597无法启动--journal，终止

我做了下一个：

cd / var / lib / mongodb
rm -r journal /

Answer 5

如果您使用的是Mac Catalina：

mongod --dbpath = /用户/用户/数据/数据库离开这个窗口

然后您可以在另一个窗口中键入。

mongo

显示数据库

如何解决错误：MongoDB中不存在dbpath（/ data / db /）

5 个答案:

从命令行

mongo
