Mount the SeaweedFS via FUSE
# Mount by fstab
```
$ # on linux
$ sudo apt-get install fuse
$ sudo echo 'user_allow_other' >> /etc/fuse.conf
$ sudo mv weedfuse /sbin/mount.weedfuse
$ # on Mac
$ sudo mv weedfuse /sbin/mount_weedfuse
```
On both OS X and Linux, you can add one of the entries to your /etc/fstab file like the following:
```
# mount the whole SeaweedFS
localhost:8888/ /home/some/mount/folder weedfuse
# mount the SeaweedFS sub folder
localhost:8888/sub/dir /home/some/mount/folder weedfuse
# mount the SeaweedFS sub folder with some options
localhost:8888/sub/dir /home/some/mount/folder weedfuse user
```
To verify it can work, try this command
```
$ sudo mount -av
...
/home/some/mount/folder : successfully mounted
```
If you see `successfully mounted`, try to access the mounted folder and verify everything works.
To debug, run these:
```
$ weedfuse -foreground localhost:8888/ /home/some/mount/folder
```
To unmount the folder:
```
$ sudo umount /home/some/mount/folder
```
<!-- not working yet!
# Mount by autofs
AutoFS can mount a folder if accessed.
```
# install autofs
$ sudo apt-get install autofs
```
Here is an example on how to mount a folder for all users under `/home` directory.
Assuming there exists corresponding folders under `/home` on both local and SeaweedFS.
Edit `/etc/auto.master` and `/etc/auto.weedfuse` file with these content
```
$ cat /etc/auto.master
/home /etc/auto.weedfuse
$ cat /etc/auto.weedfuse
# map /home/<user> to localhost:8888/home/<user>
* -fstype=weedfuse,rw,allow_other,foreground :localhost\:8888/home/&
```
