please give the solution

Read the "Question Guidelines". Your entire 'question' is just "please give the solution". Since your subject line says you need a shared folder in RHEL 7, how about providing actual details? What kind of clients do you need to share this folder to? What kind of environment? Security? And since you're using RHEL, have you contacted RHEL for support?? You are PAYING FOR RHEL, RIGHT????

You can use either Samba (for Windows clients), or NFS (Mac, Unix/Linux clients). Samba can be used on all of them, but it depends on your needs.

If you mean Red Hat Enterprise Linux, the NFS server documentation is at https://access.redhat.com/documentat...n_guide/ch-nfs, whereas Samba is covered in https://access.redhat.com/documentat...ers#sect-Samba.
