NFS 求助，无法挂载

wzgskyer

想要安装NFS，但是挂载始终失败，之前尝试一次成功了，后来就一直失败，希望大牛能帮忙看下怎么回事，谢谢。
服务器端：防火墙已经关了，相关服务也都启动了。

尝试直接在本地挂载也是失败了，客户端挂载也是报同样的错误。

haooooaaa

你的  /etc/exports  如何折腾的？

折腾？没有折腾啊。。
# cat /etc/exports
/home/NFSshare/ReadOnly *(rw,sync,all_squash,insecure)
我看网上说加insecure可以解决部分问题，但是还是没用。。我试过
/home/NFSshare/ReadOnly *(rw)
也是不行。
# cat /etc/exports
/home/NFSshare/ReadOnly *(rw)
# mount -t nfs -v localhost:/home/NFSshare/ReadOnly /home/NFSshare/writable/

关闭下selinux看看

csoho2000

exportfs –r

showmount -e 127.0.0.1

先运行上面命令试试

谢谢了，我试了下，还是不行。
showmount 是正常的
# exportfs -r
# showmount -e 127.0.0.1
Export list for 127.0.0.1:
