NFS install and configure

These instructions are a basic guide for a super-user to install and configure NFS on CentOS 7. 

1. Install NFS server

   yum install nfs-utils
   

2. Create export directory

   mkdir /opt/nfs_share
   touch /opt/nfs_share/.abiquo_repository
   chmod -R 755 /opt/nfs_share
   chown nfsnobody:nfsnobody /opt/nfs_share

3. Enable and start NFS services

   systemctl enable rpcbind
   systemctl enable nfs-server
   systemctl enable nfs-lock
   systemctl enable nfs-idmap
   systemctl start rpcbind
   systemctl start nfs-server
   systemctl start nfs-lock
   systemctl start nfs-idmap

4. Edit /etc/exports to share the NFS directory

   /opt/nfs_share    *(rw,sync,no_root_squash,no_all_squash)

5. Restart NFS service

   systemctl restart nfs-server
