NFS网络文件系统

NFS应用实例
服务端部分
1安装nfs
sudo yum install nfs-utils rpcbind


2添加允许客户端挂载的设备及相关权限（默认没有内容）

sudo vim /etc/exports

 /mnt/lanmao_seal/data 10.139.51.142(rw,no_root_squash,all_squash,anonuid=65534,anongid=65534，async)      

 /mnt/lanmao_seal/data 10.253.43.161(rw,no_root_squash,all_squash,anonuid=65534,anongid=65534,async)

 /mnt/lanmao_seal/nfs_lanmao 10.139.51.142(rw,no_root_squash,all_squash,anonuid=65534,anongid=65534,async)

 /mnt/lanmao_seal/nfs_lanmao 10.253.43.161(rw,no_root_squash,all_squash,anonuid=65534,anongid=65534,async)

#65534是nfsnobody用户和组的id号，安装nfs服务后会自动创建nfsnobody用户和组。

3启动服务
sudo service rpcbind start
sudo service nfs start

存储目录的所有者和组权限该为nfsnobody和nfsnobody(服务端存储文件的目录)

客户端部分
1安装nfs
sudo yum install nfs-utils rpcbind


2挂载nfs服务器目录到客户端
sudo mount -t nfs 10.139.98.4:/mnt/lanmao_seal/nfs_lanmao /mnt/nfs_lanmao
sudo mount -t nfs 10.139.98.4:/mnt/lanmao_seal/data /data
