In one of my assignments on CentOS 7, I am trying to NFS mount /home directory from management node to client node. I have given the commands I have tried below.
I tried to disable firewall, but it's asking for password which I don't have, and so it didn't work. Then I made changes in the exports file as below, but nothing to my avail. PFB the commands I ran:
[user@node-1 ~]$ ssh -i ~/.ssh/key node-2 Last login: Wed Sep 19 12:56:36 2018 from 22.214.171.124 [user@node-2 ~]$ sudo mount -t nfs 126.96.36.199:/home /home mount.nfs: access denied by server while mounting 188.8.131.52:/home [user@node-2 ~]$ exit logout Connection to node-2 closed. [user@node-1 ~]$ systemctl disable firewalld ==== AUTHENTICATING FOR org.freedesktop.systemd1.manage-unit-files === Authentication is required to manage system service or unit files. Authenticating as: Cloud User (user) Password: polkit-agent-helper-1: pam_authenticate failed: Authentication failure ==== AUTHENTICATION FAILED === Failed to execute operation: Access denied [user@node-1 ~]$ sudo vi /etc/exports
The changes made in the exports file are as:
And then I tried updating the changes but got another error
[user@node-1 ~]$ exportfs -ra exportfs: could not open /var/lib/nfs/.etab.lock for locking: errno 13 (Permission denied) exportfs: can't lock /var/lib/nfs/etab for writing
Can anyone help me mount the /home directory from the management server to client server, please?
