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/00-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(5) and sysctl.d(5).
net.ipv6.conf.all.disable_ipv6 = 1
net.ipv6.conf.default.disable_ipv6 = 1
net.core.netdev_max_backlog = 262144
net.core.somaxconn = 4096
net.ipv4.tcp_max_orphans = 327680
net.ipv4.tcp_max_syn_backlog = 262144
net.ipv4.tcp_timestamps = 0
net.ipv4.tcp_synack_retries = 1
net.ipv4.tcp_syn_retries = 1
net.ipv4.tcp_tw_recycle = 1
net.ipv4.tcp_tw_reuse = 1
net.ipv4.tcp_fin_timeout = 1
net.ipv4.tcp_keepalive_time = 120
net.ipv4.ip_local_port_range = 32768   65000
net.ipv4.tcp_syncookies = 1
net.ipv4.tcp_max_syn_backlog = 8192
net.ipv4.tcp_rmem = 4096 4096 16777216
net.ipv4.tcp_wmem = 4096 4096 16777216
net.ipv4.tcp_mem = 94500000 915000000 927000000
net.ipv4.tcp_sack = 0
fs.file-max = 1300000
net.ipv4.ip_nonlocal_bind = 1
kernel.softlockup_panic = 1
kernel.panic = 30

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
