yum install nfs-utils mkdir /var/nfsshare chmod -R 777 /var/nfsshare/
在/etc/exports中加入内容
/var/nfsshare 192.168.174.0/24(insecure,rw,sync,no_root_squash,no_all_squash)
记住这个192.168.174.0/24是访问端的地址，也可以直接设置成*
systemctl enable rpcbind systemctl enable nfs-server systemctl enable nfs-lock systemctl enable nfs-idmap systemctl start rpcbind systemctl start nfs-server systemctl start nfs-lock systemctl start nfs-idmap exportfs
本地mount测试一下
mkdir -p /mnt/nfs/var/nfsshare mount -t nfs 192.168.174.10:/var/nfsshare /mnt/nfs/var/nfsshare/
因为涉及到iptables问题，需要在Server端开通防火墙如下,此处折腾太长时间，感谢同事的脚本。
cp /etc/sysconfig/iptables /etc/sysconfig/iptables.bak.$(date "+%Y%m%d%H%M%S"); sed -i ‘/.*--dport 22 -j ACCEPT.*/a\-A INPUT -p tcp -m state --state NEW -m tcp --dport 20048 -j ACCEPT‘ /etc/sysconfig/iptables; sed -i ‘/.*--dport 22 -j ACCEPT.*/a\-A INPUT -p tcp -m state --state NEW -m tcp --dport 111 -j ACCEPT‘ /etc/sysconfig/iptables; sed -i ‘/.*--dport 22 -j ACCEPT.*/a\-A INPUT -p tcp -m state --state NEW -m tcp --dport 2049 -j ACCEPT‘ /etc/sysconfig/iptables; sed -i ‘/.*--dport 22 -j ACCEPT.*/a\-A INPUT -p udp --dport 20048 -j ACCEPT‘ /etc/sysconfig/iptables; sed -i ‘/.*--dport 22 -j ACCEPT.*/a\-A INPUT -p udp --dport 111 -j ACCEPT‘ /etc/sysconfig/iptables; sed -i ‘/.*--dport 22 -j ACCEPT.*/a\-A INPUT -p udp --dport 2049 -j ACCEPT‘ /etc/sysconfig/iptables; systemctl restart iptables;
