mongodb - 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 社区版。

我通过首先启动服务然后使用任何客户端进行连接来成功测试了我的连接。 (robomongo 和 umongo)。

现在由于我的工作类型，我将把 GB 的文件存储到我的机器上。因此我需要更改 mongoDB 的位置。所以我按照以下步骤(也提到了here):

步骤 1 :
在 mongod.conf 打开 \etc
步骤 2 :

编辑所需的路径。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

Step 4 : 递归更新新目录权限为777

现在我似乎无法在那之后启动 mongoDB。我检查了 /var/log/mongodb/mongod.lod 的日志文件，似乎存在如下所述的权限问题
/home/shouman/mongodb/WiredTiger.wt
现在你可以注意到其中的一些注释

mongoDB 现在可以看到新位置。 (它还创建了两个锁文件)

我检查了这个特定文件的权限，它似乎没问题(检查最后的图片)

我尝试重新启动 mongoDB 但仍然是同样的问题

这是完整的 日志输出

Answer 1

好的。所以看来我还需要让 mongod 用户成为新 mongoDB driectoty 的所有者

我在这个问题中找到了答案

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