linux中nfs启动报rpcbind.socket failed to listen on sockets: Address family not supported by protocol

1、systemctl start rpcbind.service

报错：

2、解决：

vim /etc/sysctl.conf

# System default settings live in /usr/lib/sysctl.d/-system.conf.
# To override those settings, enter new settings here, or in an /etc/sysctl.d/<name>.conf file
#
# For more information, see sysctl.conf() and sysctl.d().
net.ipv6.conf.all.disable_ipv6 = 1
net.ipv6.conf.default.disable_ipv6 = 1
net.core.netdev_max_backlog =
net.core.somaxconn =
net.ipv4.tcp_max_orphans =
net.ipv4.tcp_max_syn_backlog =
net.ipv4.tcp_timestamps =
net.ipv4.tcp_synack_retries =
net.ipv4.tcp_syn_retries =
net.ipv4.tcp_tw_recycle =
net.ipv4.tcp_tw_reuse =
net.ipv4.tcp_fin_timeout =
net.ipv4.tcp_keepalive_time =
net.ipv4.ip_local_port_range =
net.ipv4.tcp_syncookies =
net.ipv4.tcp_max_syn_backlog =
net.ipv4.tcp_rmem =
net.ipv4.tcp_wmem =
net.ipv4.tcp_mem =
net.ipv4.tcp_sack =
fs.file-max =
net.ipv4.ip_nonlocal_bind =
kernel.softlockup_panic =
kernel.panic = 

将

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

改成

net.ipv6.conf.all.disable_ipv6 = 0
net.ipv6.conf.default.disable_ipv6 = 0

3、重启

systemctl start rpcbind.service

systemctl start nfs.service
