三 NFS简单应用
[sql]
--第一步,安装软件
[root@serv01 ~]# yum install nfs* -y
--第二步,修改配置文件
[root@serv01 ~]# vim /etc/exports
[root@serv01 ~]# cat /etc/exports
/share *(ro)
#共享目录 共享IP地址或者网段 共享参数
[root@serv01 ~]# mkdir /share
--第三步,重启服务
[root@serv01 ~]# /etc/init.d/rpcbind restart
Stopping rpcbind: [ OK ]
Starting rpcbind: [ OK ]
[root@serv01 ~]# /etc/init.d/nfs restart
Shutting down NFS mountd: [ OK ]
Shutting down NFS daemon: [ OK ]
Shutting down NFS services: [ OK ]
Starting NFS services: [ OK ]
Starting NFS daemon: [ OK ]
Starting NFS mountd: [ OK ]
[root@serv01 ~]# exportfs -v
/share (ro,wdelay,root_squash,no_subtree_check)
--第四步,serv02挂载
#serv02
[root@serv02 ~]# mount192.168.1.11:/share /mnt
mount: wrong fs type, bad option, badsuperblock on 192.168.1.11:/share,
missing codepage or helper program, or other error
(for several filesystems (e.g. nfs, cifs) you might
need a /sbin/mount. helper program)
In some cases useful info is found in syslog - try
dmesg | tail or so
#出现这个错误,安装nfs相关的包
[root@serv02 ~]# yum install nfs* -y
[root@serv02 ~]# mount 192.168.1.11:/share/mnt
[root@serv02 ~]# cd /mnt
[root@serv02 /]# umount /mnt
[root@serv02 /]# mkdir /data
[root@serv02 /]# mount 192.168.1.11:/share/data
[root@serv02 /]# df -h
