rpc.nfsd(8) System Manager's Manual rpc.nfsd(8) NAME rpc.nfsd - NFS Service process
SYNOPSIS/usr/sbin/rpc.nfsd [options] nproc DESCRIPTION
rpc.nfsd The program is implemented in the user space layer NFS service , The main functions are nfsd Kernel module to handle . User space program master
To specify which socket the kernel space layer service listens on , How many kernel threads are used . rpc.mountd Service provision ancillary services , For processing NFS Client's mount request . OPTIONS-d
or --debug Open debug log . -H or --host hostname
By default ,rpc.nfsd Will accept on all known network interface addresses NFS request , Use this option to specify a
Specific host name ( or IP address ), bring nfsd Only accept the host name ( or IP) Of NFS request . be careful lockd( provide NFS
Program of file lock service ) Still accept requests on all known network interfaces , In the future Kernel May change . You can specify this option more than once , bring nfsd Monitoring is implemented on multiple interfaces nfs Multiple instances .
-p or --port port appoint nfsd For acceptance NFS Requested listening port . default rpc.nfsd The listening port is 2049. -r or --rdma
Specify all standards RDMA port (nfsrdma, port 20049) On NFS Request should be processed . ( translator's note :RDMA(Remote Direct Memory
Access) Can be almost unnecessary cpu Participation of , Copy data directly Operation to specified address memory space on remote machine , Will replace tradition DMA pattern )--rdma=port
Turn on a standby port to listen RDMA request - Port is /etc/services One of the items listed in . -N or --no-nfs-version vers
This option allows rpc.nfsd Not to specific versions of NFS Provision of services . current rpc.nfsd Supported NFS Version has 2,3,4 And the latest Of 4.1. -s or --syslog
By default ,rpc.nfsd Error messages will be sent ( If it's on debug information , It also includes debug information ) Record to stderr.
This option allows rpc.nfsd Record information to syslog in . be careful , Error encountered while processing options , Still output to stderr.-T or --no-tcp
prohibit rpc.nfsd Receive client initiated TCP connect .-U or --no-udp prohibit rpc.nfsd Receive client initiated UDP connect . -V or --nfs-
version vers This option allows rcp.nfsd To a specific version NFS Provision of services . current rpc.nfsd Supported NFS Version has 2,3,4 And the latest 4.1. -L or
--lease-time seconds set up NFSv4 Lease time for (lease-time). It means how long the client needs to server End to confirm their status once .
The valid range is 10-3600 second . -G or --grace-time seconds set up NFSv4 Of grace-time
,NFSv2 and NFSv3 Of NLM. New file open request (NFSv4) And new file locks (NLM) In this section
Period not allowed , Clients will not be able to recover until this period of time has passed , To continue to open a new file or apply for a file lock . nproc
appoint NFS Number of threads served . Only one thread is started by default , However, multiple threads should be specified to ensure optimal performance . Actual number
The quantity should depend on NFS The number of clients and the amount of load they bring , but 8 One thread is a good starting point for the number of threads . use nfsstat(8) Tools can test the impact of changing the number of threads .
If NFS Service is running , Then specify host,port,protocol Will be ignored , Only options that specify the number of threads will
take effect , And will adjust ( Increase or decrease ) The current number of threads matches the specified value , In particular, specify 0 Threads will stop All threads , And therefore closes all open connections .
( translator's note : in other words nproc Set to 0 Can be used to kill safely nfsd process , stay CentOS 7 upper nfs.service And that's exactly what it did ) NOTES If the
program is built with TI-RPC support, it will enable any protocol and address
family combinations that are marked visiblein the netconfig database. SEE ALSO
