Ubuntu更改mongoDB的位置导致连接失败（不允许操作）

Question

所以我按照here提供的说明在Ubuntu上安装了MongoDB Community Edition。

我首先启动了服务，然后使用任何客户端进行连接，成功测试了我的连接。 （robomongo和umongo）。

现在因为我的工作类型，我将把GB文件存储到我的机器上。因此我需要更改mongoDB的位置。所以我按照下面的步骤（提到here）：

第1步： 在mongod.conf

打开\etc

第2步：

编辑所需帐户的路径。我的新路径如下

dbPath: /home/shouman/mongodb

第3步：将数据从旧路径复制到新路径

第4步：以递归方式将新目录权限更新为777

现在我似乎无法启动mongoDB。我在/var/log/mongodb/mongod.lod检查了日志文件，似乎存在如下所述的权限问题

/home/shouman/mongodb/WiredTiger.wt

现在您可以注意到

中的一些注释

1. mongoDB现在可以看到新位置。 （它还创建了两个锁定文件）
2. 我检查了这个特定文件的权限，看起来没问题（查看最后的图片）
3. 我尝试重新启动mongoDB但仍然存在同样的问题

以下是完整的日志输出

Answer 1

行。所以我似乎还需要让mongod用户成为新mongoDB driectoty的拥有者

我在这个问题中找到了答案

MongoDB service doesn't start. errno:13 Permission denied
