• NFS服务器实现文件共享


    • NFS服务器运行原理
    • 实战配置NFS服务器
    • 配置Samba服务器及实现文件共享

           (一)NFS器服务端描述

    1.  NFS服务器: Network File System,网络文件系统使FreeBSD支持的一种
    2. 系统安装,直接用yum方式安装  # yum -y install NFS*
    3. 启动服务 #/etc/init.d/nfs start    
       启动显示失败:annot register service: RPC: Unable to receive; errno = Connection refused
      rpc.rquotad ,需要启动rpc服务

    4. # /etc/init.d/nfs start


      Starting NFS services: [ OK ]
      Starting NFS quotas: Cannot register service: RPC: Unable to receive; errno = Connection refused
      rpc.rquotad: unable to register (RQUOTAPROG, RQUOTAVERS, udp).
      [FAILED]
      Starting NFS mountd: [FAILED]
      Starting NFS daemon: rpc.nfsd: writing fd to kernel failed: errno 111 (Connection refused)
      rpc.nfsd: unable to set any sockets for nfsd
      [FAILED]  

      # /etc/init.d/rpcbind start
      Starting rpcbind: [ OK ]

           4. 查看NFS服务启动端口  # netstat -antup | grep 2049

    # chkconfig nfs on
    # chkconfig --list nfs
    nfs                0:off    1:off    2:on    3:on    4:on    5:on    6:off

           5. 设置开机自启动  

           6. 查看共享目录

        

    # showmount -e 192.168.0.35
    Export list for 192.168.0.35:

           7.  设置共享目录

            编辑 #vim /etc/exports  

         

                   /mysh * {rwx}     ### 允许访问的网段   用户 权限  ,*表示所有用户

                                              ### 多网段分开写

          8.  重启NFS服务,查看NFS共享,并进行挂载

          

    # showmount -e 192.168.0.35
    Export list for 192.168.0.35:
    /mysh *# mount -t nfs 192.168.0.35:/mysh/ /opt/# df -h
    Filesystem           Size  Used Avail Use% Mounted on
    /dev/sda3             19G  5.1G   13G  29% /
    tmpfs                427M   72K  427M   1% /dev/shm
    /dev/sda1             97M   34M   59M  37% /boot
    192.168.0.35:/mysh/  9.5G  1.1G  8.0G  12% /opt

        9.  开机自动挂载 编辑 /etc/fstab 文件,添加即可

       10.权限问题   1)服务本身权限

                           2)目录权限    # chmod 777 -R /mysh/

         

    # grep nfs /etc/passwd
    rpcuser:x:29:29:RPC Service User:/var/lib/nfs:/sbin/nologin
    nfsnobody:x:65534:65534:Anonymous NFS User:/var/lib/nfs:/sbin/nologin
