Mount Windows Shared Folders

This section provides a tutorial example on how to mount Windows shared folders on Linux systems. 'cifs-utils' device driver is needed.

If you have a Windows computer on the local network, you can share a folder with your Linux computer. Here is what I did to share a folder on my Windows 10 with my CentOS 8 computer.

1. On my Windows 10 computer, create share folder and make it available for sharing:

2. On my CentOS 8 computer, install cifs-utils device drive and mount the shared folder. Note that "192.168.1.7" is the IP address of my Windows 10 computer. "herong" is the username on Windows 10 computer.

herong$ sudo dnf install cifs-utils
...
installed:
  cifs-utils-6.8-3.el8.x86_64

herong$ sudo mkdir /mnt/share

herong$ sudo mount -t cifs -o username=herong //192.168.1.7/share /mnt/share
Password for herong@//192.168.1.7/share:  ********

3. Verify the shared folder. It works as expected!

herong$ sudo touch /mnt/share/junk

herong$ sudo ls -l /mnt/share/junk
-rwxr-xr-x. 1 root root 0 Oct 10 22:31 /mnt/share/junk

4. To mount it under a private user and group, you need to specify additional options on the "mount" command. For example, the following command mounts the shared folder for me to access only:

herong$ sudo mount -t cifs \
  -o username=herong,uid=herong,gid=herong,dir_mode=0700,file_mode=0700 \
  //192.168.1.7/share /mnt/share

herong$ ls -l /mnt
drwx------. 2 herong herong     78 Oct 10 22:49 share

Cool. This is perfect for me to transfer files between my Windows 10 and CentOS 8 computer!

5. To mount it for the Apache Web server to use, you need to give "read/execute" permission and override its SELinux context type from "cifs_t" to "tmp_t":

[herong@mail ~]$ ls -lZ /mnt
drwx------.  2 herong herong unconfined_u:object_r:cifs_t:s0 share

herong$ sudo mount -t cifs \
  -o username=herong,uid=herong,gid=herong,dir_mode=0755,file_mode=0755,\
  context=unconfined_u:object_r:tmp_t:s0 //192.168.1.7/share /mnt/share

drwxr-xr-x.  2 herong herong unconfined_u:object_r:tmp_t:s0 share

For more information on "cifs-utils" device driver, run "man mount.cifs" command to read its man page.
