Step-by-step – Samba File Sharing on CentOS 7

Setting Up Server

2. 2. Installing Samba Server

   Then to Install Samba Server on CentOS
   Simply play:

   sudo yum install samba*

   Authenticate with the User Admin Pass.
   If Got “User is Not in Sudoers file” then see: How to Enable sudo.
   This Setup includes the Utilities for File and Printer Sharing.

3. 3. Configuring Samba Server

   Then Edit the Samba Config File
   With:

   sudo nano /etc/samba/smb.conf

   To Quick enabling a generic Read Only access with No Security use:

   [sharing]
   comment = Sharing Directory
   path = /home/[myUser]/Public
   browseable = yes
   read only = yes
   guest ok = yes
   

   Just Replace [myUser] with your Real username you can Check running:

   whoami

   This to enable the default Sharing Location in your Home Folder.
   Else for a Password protected Access append:

   [sharing]
   comment = Sharing Directory
   path = /home/[myUser]/Public
   browseable = yes
   security = user/nencrypt passwords = yes
   

   And to make a Writable Share set “writable = yes” in the Configuration.
   Moreover, if you store sentitive Data and you have a Static IP then you should limit the allowed Hosts appending something like: “allow hosts = 127.0.0.1 192.168.1.0/24”.
   Last, to Add you User to the Samba enabled Users play:

   sudo smbpasswd -a `whoami`

   This to setup a Login for your current Username (Set a Different Password that for Admin if you Share it!)
   Ctrl+x to Save & Exit from nano Editor :)

4. 4. Setting up Firewall

   Now to Configure SELinux & Firewall
   Run one by one:

   sudo setsebool -P samba_export_all_rw on

   sudo firewall-cmd --add-service=samba --permanent

   sudo firewall-cmd --reload

5. 5. Enabling Samba Server

   Then to Enable Samba & Winbind Services
   Simply play:

   sudo systemctl enable smb nmb

   sudo systemctl start smb nmb

6. 6. Looking up Server IP

   Find the Server IP often under eth0 on the inet Line:
