如何让 mongo 在 ec2上使用挂载的驱动器?我真的不明白。我在 ec2上附加了一个卷,将驱动器格式化为 root,并以 root 启动,但是作为 root 我不能访问?我正在运行 ubuntu 12.04。没有其他蒙古人跑了
我看到 mongo 在/data (即/data/db)中创建了一个“ db”dir
cd /
ls -al
drwxr-xr-x 4 root root 4096 Mar 5 16:28 data
cd /data
ls -al
total 28
drwxr-xr-x 4 root root 4096 Mar 5 16:28 .
drwxr-xr-x 24 root root 4096 Mar 5 16:28 ..
