8.5. Starting and Stopping the NFS Server
Prerequisites
- For servers that support NFSv2 or NFSv3 connections, the
rpcbind
[1] service must be running. To verify thatrpcbind
is active, use the following command:$
systemctl status rpcbind
To configure an NFSv4-only server, which does not requirerpcbind
, see Section 8.6.7, “Configuring an NFSv4-only Server”. - On Red Hat Enterprise Linux 7.0, if your NFS server exports NFSv3 and is enabled to start at boot, you need to manually start and enable the
nfs-lock
service:#
systemctl start nfs-lock
#
systemctl enable nfs-lock
On Red Hat Enterprise Linux 7.1 and later,nfs-lock
starts automatically if needed, and an attempt to enable it manually fails.
Procedures
- To start an NFS server, use the following command:
#
systemctl start nfs
- To enable NFS to start at boot, use the following command:
#
systemctl enable nfs
- To stop the server, use:
#
systemctl stop nfs
- The
restart
option is a shorthand way of stopping and then starting NFS. This is the most efficient way to make configuration changes take effect after editing the configuration file for NFS. To restart the server type:#
systemctl restart nfs
- After you edit the
/etc/sysconfig/nfs
file, restart the nfs-config service by running the following command for the new values to take effect:#
systemctl restart nfs-config
- The
try-restart
command only startsnfs
if it is currently running. This command is the equivalent ofcondrestart
(conditional restart) in Red Hat init scripts and is useful because it does not start the daemon if NFS is not running.To conditionally restart the server, type:#
systemctl try-restart nfs
- To reload the NFS server configuration file without restarting the service type:
#
systemctl reload nfs
