No se puede iniciar NFS en Centos 7: no se pudo emitir la llamada al método: no existe tal archivo o directorio

No puedo iniciar un servidor NFS en CentOS7.

Los paquetes descargados:

yum -y install nfs-utils
yum -y install nfs-utils-lib

Habilitar / iniciar servicios

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

Lo que lleva a :

systemctl enable nfs-lock
Failed to issue method call: No such file or directory
systemctl enable nfs-idmap
Failed to issue method call: No such file or directory

Creado el recurso compartido:

mkdir -p /test
chmod 777 /test

bien exportado:

exportfs
/test           clientip/24

Sin embargo, al realizar el systemctlreinicio nfs-server, falla con un error de dependencia, journalctlmuestra:

[user@server /]# journalctl -xn | grep failed
-- Subject: Unit proc-fs-nfsd.mount has failed
-- Unit proc-fs-nfsd.mount has failed.
-- The result is failed.

El cliente informa, y ​​supongo que es normal según los errores anteriores:

RPC: Remote system errorRPC: Port mapper failure - RPC: Timed out.

Resolví este problema con la publicación de @ user136564.

Esto resolvió mi problema https://www.centos.org/forums/viewtopic.php?f=47&t=53896

Encontré que mi problema era que rpcbind no se iniciará en el arranque a pesar de que lo habilité en systemd y pude iniciarlo manualmente.

Estos comandos son lo que hice en CentOS Linux versión 7.2.1511 (Core)

Instalar nfs-utils

yum install -y nfs-utils

Agregar texto a /etc/fstab

192.168.1.100:/mnt/nfs-server /mnt/nfs-client nfs defaults,nofail,x-systemd.automount 0 0

Algunos artículos dicen que noauto,x-systemd.automountes mejor, pero funcionó sin noautomí.

Compruebe si el montaje funciona

systemctl start rpcbind
systemctl enable rpcbind
mount -a

Solucione el problema CentOS 7 no montará automáticamente NFS en el arranque

[Install]
WantedBy=multi-user.target

[Install]
WantedBy=nfs.target

Habilitar servicios relacionados

systemctl enable nfs-idmapd.service 
systemctl enable rpc-statd.service 

systemctl enable rpcbind.socket

systemctl status nfs-idmapd.service -l
systemctl status rpc-statd.service –l

Luego reinicié el sistema operativo, lo tengo.

shutdown -r now
