Several important steps during the setup of the SAMBA server on centos 7 ---win10.

     The general steps follow closely with the link  https://www.tecmint.com/install-samba4-on-centos-7-for-file-sharing-on-windows/.
     But i met some problems after the installation, I have successfully resolved them and I write the methods here.
 Problem  1: Win10 cann't show the centos 7 in the "network neighbor". 
 Method:   open the SMB1.0 in the windows feature pannel located in the control panel. Remember , restarting win10. 

problem 2: I have setup a "anonymous file sharing" SAMBA, but win10 still need the user name and password . 

Method: Just create a user name and set its password with the following  command .

                     sudo smbpasswd -a  username

After this step, I can enter the SAMBA folder smoothly, I remembered that  I only input the username and password one time.

This is all my experience  in this weekends.  

 Thanks
