启动nfs服务时报错 systemd: rpcbind.socket failed to listen on sockets: Address family not supported by pro

问题描述

在使用 “sudo systemctl restart nfs” 命令启动 nfs 服务时报错，/var/log/message 文件中有如下错误

Sep 29 09:39:47 myhost systemd: Starting Preprocess NFS configuration...
Sep 29 09:39:47 myhost systemd: rpcbind.socket failed to listen on sockets: Address family not supported by protocol
Sep 29 09:39:47 myhost systemd: Failed to listen on RPCbind Server Activation Socket.

解决办法

• 修改 /etc/sysctl.conf 文件

  添加如下两行

  net.ipv6.conf.all.disable_ipv6 = 1
  net.ipv6.conf.default.disable_ipv6 = 1
  

• 修改 rpcbind.socket 文件

  首先查找 rpcbind.socket 文件路径

  $ sudo find /etc/ -name '*rpcbind.socket*'
  /etc/systemd/system/sockets.target.wants/rpcbind.socket
  

  编辑 /etc/systemd/system/sockets.target.wants/rpcbind.socket 文件，将其中 ListenStream 关于IPv6的部分注释掉，如下：

  [Unit]
  Description=RPCbind Server Activation Socket
  
  [Socket]
  ListenStream=/var/run/rpcbind.sock
  #ListenStream=[::]:111
  ListenStream=0.0.0.0:111
  BindIPv6Only=ipv6-only
  
  [Install]
  WantedBy=sockets.target
  

• 重新启动 nfs 服务

  $ sudo systemctl daemon-reload
  $ sudo systemctl restart nfs
