NFS服务器搭建 unbuntu

1. 查看是否有NFS服务hduser@master:/home/nfs-free$ sudo /etc/init.d/nfs-kernel-server status[sudo] password for hduser: nfsd running2. 如果没有安装apt-get install nfs-kernel-server nfs-common 3. 启动NFS服务器hduser@master:/home/nfs-free$ sudo /etc/init.d/nfs-kernel-server start * Exporting directories for NFS kernel daemon...                        [ OK ]  * Starting NFS kernel daemon                                            [ OK ] hduser@master:/home/nfs-free$ 4. 创建挂载目录    a. 在挂载目录中写入共享文件5. 修改/etc/exports格式# /etc/exports: the access control list for filesystems which may be exported#       to NFS clients.  See exports(5).## Example for NFSv2 and NFSv3:# /srv/homes       hostname1(rw,sync,no_subtree_check) hostname2(ro,sync,no_subtree_check)## Example for NFSv4:# /srv/nfs4        gss/krb5i(rw,sync,fsid=0,crossmnt,no_subtree_check)# /srv/nfs4/homes  gss/krb5i(rw,sync,no_subtree_check)#第二列：可访问主机192.168.152.13 指定IP地址的主机 nfsclient.test.com 指定域名的主机 192.168.1.0/24 指定网段中的所有主机 *.test.com        指定域下的所有主机 *                       所有主机来自 <http://www.linuxidc.com/Linux/2012-05/61527.htm> 最好在/etc/exports中的权限中加入no_subtree_check，可以提高传输率6. 本地挂载hduser@master:/home/nfs-free$ sudo mount -t nfs master:/home/nfs-free /mnthduser@master:/home/nfs-free$ cd /mnthduser@master:/mnt$ lsfree.txt7. 在客户端查看共享目录hduser@data1:/mnt$ showmount -e 192.168.56.100Export list for 192.168.56.100:/home/nfs-free data1hduser@data1:/mnt$ showmount -e masterExport list for master:/home/nfs-free data18. 挂载目录hduser@data1:/mnt$ sudo mount master:/home/nfs-free /mnt[sudo] password for hduser: mount.nfs: /mnt is busy or already mountedhduser@data1:/mnt$ lsfree.txt  free.txt~9. 查看NFS状态hduser@data1:/mnt$ mount/dev/sda1 on / type ext4 (rw,errors=remount-ro)proc on /proc type proc (rw,noexec,nosuid,nodev)sysfs on /sys type sysfs (rw,noexec,nosuid,nodev)none on /sys/fs/cgroup type tmpfs (rw)none on /sys/fs/fuse/connections type fusectl (rw)none on /sys/kernel/debug type debugfs (rw)none on /sys/kernel/security type securityfs (rw)udev on /dev type devtmpfs (rw,mode=0755)devpts on /dev/pts type devpts (rw,noexec,nosuid,gid=5,mode=0620)tmpfs on /run type tmpfs (rw,noexec,nosuid,size=10%,mode=0755)none on /run/lock type tmpfs (rw,noexec,nosuid,nodev,size=5242880)none on /run/shm type tmpfs (rw,nosuid,nodev)none on /run/user type tmpfs (rw,noexec,nosuid,nodev,size=104857600,mode=0755)none on /sys/fs/pstore type pstore (rw)tracefs on /var/lib/ureadahead/debugfs/tracing type tracefs (rw,relatime)rpc_pipefs on /run/rpc_pipefs type rpc_pipefs (rw)systemd on /sys/fs/cgroup/systemd type cgroup (rw,noexec,nosuid,nodev,none,name=systemd)gvfsd-fuse on /run/user/1000/gvfs type fuse.gvfsd-fuse (rw,nosuid,nodev,user=hduser)/dev/sr0 on /media/hduser/VBOXADDITIONS_5.1.8_111374 type iso9660 (ro,nosuid,nodev,uid=1000,gid=1000,iocharset=utf8,mode=0400,dmode=0500,uhelper=udisks2)master:/home/nfs-free on /mnt type nfs (rw,vers=4,addr=192.168.56.100,clientaddr=192.168.56.101)gvfsd-fuse on /home/hduser/.gvfs type fuse.gvfsd-fuse (rw,nosuid,nodev)hduser@data1:/mnt$ mount |grep nfsmaster:/home/nfs-free on /mnt type nfs (rw,vers=4,addr=192.168.56.100,clientaddr=192.168.56.101)10. 对共享目录下的文件操作hduser@data1:~$ cp /mnt/free.txt ~/Desktop/11. 开机自动挂载    修改/etc/fstab    ubuntu /etc/fstab解析
