导读：出现此类错误原因大致为：权限问题防火墙机制问题共享配置文件问题搭建好nfs服务后，在client端进行挂载时，提示： [[email?protected] media]# mount -t nfs 192.168 . 0.124 :/server/tools/repo /media/centos/ mount.nfs: access denied by server w

出现此类错误原因大致为：

权限问题
防火墙机制问题
共享配置文件问题

搭建好nfs服务后，在client端进行挂载时，提示：

[[email?protected] media]# mount -t nfs 192.168.0.124:/server/tools/repo /media/centos/ mount.nfs: access denied by server while mounting 192.168.0.124:/server/tools/repo

查看了一下client端是否被占用了：

[[email?protected] media]# mount -t nfs 192.168.0.124:/server/tools/repo /media/centos/
mount.nfs: access denied by server while mounting 192.168.0.124:/server/tools/repo
[[email?protected] media]# mount
/dev/sda3 on / type ext4 (rw)
proc on /proc type proc (rw)
sysfs on /sys type sysfs (rw)
devpts on /dev/pts type devpts (rw,gid=5,mode=620)
tmpfs on /dev/shm type tmpfs (rw,rootcontext="system_u:object_r:tmpfs_t:s0")
/dev/sda1 on /boot type ext4 (rw)
none on /proc/sys/fs/binfmt_misc type binfmt_misc (rw)
sunrpc on /var/lib/nfs/rpc_pipefs type rpc_pipefs (rw)

发现并没有，然并卵。

接着就上server端查看/etc/exports配置文件：

[[email?protected] scripts]# cat /etc/exports
exporting 192.168.0.*:/server/tools/repo
exporting 192.168.0.*:/data

把192.168.0.24的/server/tools/repo共享给同一个网段的所有服务器，把IP格式规范为192.168.0.0/24或192.168.0.0/255.255.255.0

[[email?protected] scripts]# vim /etc/exports 
[[email?protected] scripts]# exportfs -rv
exporting 192.168.0.0/24:/server/tools/repo
exporting 192.168.0.0/24:/data
[[email?protected] scripts]# showmount -e 127.0.0.1
Export list for 127.0.0.1:
/server/tools/repo 192.168.0.0/24
/data              192.168.0.0/24

我们再从client端上从新挂载：

[[email?protected] media]# mount -t nfs 192.168.0.124:/server/tools/repo /media/centos/
[[email?protected] media]# df -h
Filesystem                        Size  Used Avail Use% Mounted on
/dev/sda3                          19G  1.8G   16G  11% /
tmpfs                             491M     0  491M   0% /dev/shm
/dev/sda1                         194M   29M  155M  16% /boot
192.168.0.124:/server/tools/repo   19G  6.7G   11G  39% /media/centos

is ok!
