18.5. Starting and Stopping NFS
To run an NFS server, the portmap service must be running. To verify that portmap is active, type the following command as root:
/sbin/service portmap status
If the portmap service is running, then the nfs service can be started. To start an NFS server, as root type:
/sbin/service nfs start
nfslock also has to be started for both the NFS client and server to function properly. To start NFS locking as root type: /sbin/service nfslock start. If NFS is set to start at boot, please ensure that nfslock also starts by running chkconfig --list nfslock. If nfslock is not set to on, this implies that you will need to manually run the /sbin/service nfslock start each time the computer starts. To set nfslock to automatically start on boot, type the following command in a terminal chkconfig nfslock on.
To stop the server, as root, type:
/sbin/service nfs stop
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, as root, type:
/sbin/service nfs restart
The condrestart (conditional restart) option only starts nfs if it is currently running. This option is useful for scripts, because it does not start the daemon if it is not running.
To conditionally restart the server, as root, type:
/sbin/service nfs condrestart
To reload the NFS server configuration file without restarting the service, as root, type:
/sbin/service nfs reload
By default, the nfs service does not start automatically at boot time. To configure the NFS to start up at boot time, use an initscript utility, such as /sbin/chkconfig, /usr/sbin/ntsysv, or the Services Configuration Tool program. Refer to Chapter 15, Controlling Access to Services for more information regarding these tools.
