Alpine Linux配置NFS

NFS客户端

备注

NFS客户端的关键:

  • 安装 nfs-utils

  • 启动 nfsmount 服务(实际上是启动 rpcbind / statd / sm-notify )

  • /etc/fstab 配置NFS客户端挂载:

    192.168.6.1:/System/Volumes/Data/Users/dev /mnt nfs rw,noauto 0 0

  • 挂载服务器:

    mount /mnt

在部署 Alpine Linux运行KVM虚拟化 时，我采用了 macOS系统NFS服务 作为服务器，在没有安装 nfs-utils 之前，如果直接mount NFS，会出现如下报错:

mount: mounting 192.168.6.1:/System/Volumes/Data/Users/dev on /mnt failed: Connection refused

如果安装好 nfs-utils

apk add nfs-utils

则再次挂载，则提示报错:

flock: unrecognized option: e
BusyBox v1.33.1 () multi-call binary.

Usage: flock [-sxun] FD|{FILE [-c] PROG ARGS}

[Un]lock file descriptor, or lock FILE, run PROG

     -s      Shared lock
     -x      Exclusive lock (default)
     -u      Unlock FD
     -n      Fail rather than wait
mount.nfs: rpc.statd is not running but is required for remote locking.
mount.nfs: Either use '-o nolock' to keep locks local, or start statd.
mount.nfs: Protocol not supported
mount: mounting 192.168.6.1:/System/Volumes/Data/Users/dev on /mnt failed: Connection refused

上述报错是因为没有在客户端启动相应服务，通过 nfsmount 服务启动:

rc-service nfsmount start

提示信息:

* Caching service dependencies ...      [ ok ]
* Starting rpcbind ...                  [ ok ]
* Starting NFS statd ...                [ ok ]
* Starting NFS sm-notify ...            [ ok ]
* Mounting NFS filesystems ...          [ ok ]

再次挂载，就可以正确完成

  • 如果要在系统启动时挂载，则执行服务添加:

    rc-update add nfsmount

NFS服务

  • 对于NFS服务，则需要启动 nfs 服务:

    rc-service nfs start

  • 要在启动时启动nfs:

    rc-update add nfs
