客户端挂载
确保 /etc/init.d/portmap (Centos 5.x) 或 /etc/init.d/rpcbind (Centos 6.x)
/etc/init.d/nfslock 都是启动状态
代码语言：javascript复制[root@nfs-client ~]# mount -t nfs -o intr nfs-server:/data/nfs /mnt/nfs/
[root@nfs-client ~]# df -h

[root@nfs-client ~]# 查看本地挂载参数
使用 mount 不加参数查看
Option | Default |
|---|---|
suid/nosuid | suid |
rw/ro | rw |
dev/nodev | dev |
exec/noexec | exec |
user/nouser | nouser |
auto/noauto | auto |
NFS额外的挂载参数
Option | Default |
|---|---|
fg/bg | fg |
soft/hard | hard |
intr | - |
rsize/wsize | rsize=1024,wsize=1024 |
注意
rpcbind (Centos6.x 下) / portmap (Centos5.x 下)
总结
cat /etc/exports
no_root_squash :代表root不进行匿名替换，保留root权限
/etc/init.d/rpcbind (Centos6 与Centos5不同 ,Centos5 下是portmap)
/etc/init.d/nfs
/etc/init.d/nfslock
netstat -tulnp | grep -E ‘(rpc|nfs)’
NFS的启动信息默认会写到 /var/log/messages 里
rpcinfo -p localhost
rpcinfo -t test nfs
showmount -a localhost
showmount -e localhost
cat /var/lib/nfs/etab
exportfs -ra
grep -v “^#” /etc/sysconfig/nfs
rpcinfo -p | grep -E ‘(rquota|mount|nlock)’
iptables -A INPUT -i em1 -p tcp -s 192.168.1.0/24 -m multiport --dport 111,2049,875,892,32769,32803 -j ACCEPT
