linux映射文件夹附带源端权限管理（NFS）

NFS权限映射对应配置档配置

/volume1/local

10.22.0.70(rw,async,no_wdelay,crossmnt,insecure,no_root_squash,insecure_locks,sec=sys,anonuid=1025,anongid=100) 无映射 10.22.0.71(rw,async,no_wdelay,crossmnt,insecure,root_squash,insecure_locks,sec=sys,anonuid=1024,anongid=100) 映射root为admin 10.22.0.72(rw,async,no_wdelay,crossmnt,insecure,root_squash,insecure_locks,sec=sys,anonuid=1025,anongid=100) 映射root为guest 10.22.0.73(rw,async,no_wdelay,crossmnt,insecure,all_squash,insecure_locks,sec=sys,anonuid=1024,anongid=100) 映射所有用户为root 10.22.0.74(rw,async,no_wdelay,crossmnt,insecure,all_squash,insecure_locks,sec=sys,anonuid=1025,anongid=100) 映射所有用户为guest 10.22.0.75(ro,async,no_wdelay,crossmnt,insecure,no_root_squash,insecure_locks,sec=sys,anonuid=1025,anongid=100) 只读无映射

配置linux无映射挂载NAS共享文件夹

实验环境

DSM 6.2.3 update2
10.22.0.62

Centos8.2
10.22.0.70

NAS权限设置：

local共享文件夹：test11只读、test12只读、test13禁止访问
local共享文件夹下：
test1：test11只读、test12只读
test2：test11只读、test12禁止访问
test3：test11可读写、test12只读

挂载NAS的local共享文件夹到Centos的nfsmount目录下

Centos访问NAS NFS时权限为：

nfsmount目录：linuxtest1只读、linuxtest2只读、linuxtest3禁止访问
nfsmount目录下：
test1：linuxtest1只读、linuxtest2只读
test2：linuxtest1只读、linuxtest2禁止访问
test3：linuxtest1可读写、linuxtest2只读

NAS用户和Centos用户对应关系为

test11 = linuxtest1 = uid 1029
test12 = linuxtest2 = uid 1030
test13 = linuxtest3 = uid 1031
