Linux NFS文件共享



 

NFS文件共享服务器

NFS Server：redhat6.3新建共享目录/home/share

新建/etc/exports文件，这是NFS的配置文件，

Client:CentOS6.5新建挂载目录/share

软件列表：nfs-utils-1.2.3-26.el6.x86_64.rpm

portmap-4.0-65.2.2.1.x86_64.rpm

启动的时候先启动portmap再启动nfs

 

1. [root@www Packages]# rpm -ivhnfs-utils-1.2.3-26.el6.x86_64.rpm

error: Failed dependencies:

        libnfsidmap.so.0()(64bit)is needed by nfs-utils-1:1.2.3-26.el6.x86_64

        nfs-utils-lib>= 1.1.0-3 is needed by nfs-utils-1:1.2.3-26.el6.x86_64

处理依赖：download and install libnfsidmap-0.26-0.0.fc20.x86_64.rpm

[root@wwwsoftbynfs]# rpm -ivh libnfsidmap-0.26-0.0.fc20.x86_64.rpm

warning:libnfsidmap-0.26-0.0.fc20.x86_64.rpm: Header V3 RSA/SHA256 Signature, key ID246110c1: NOKEY

error: Failed dependencies:

        libc.so.6(GLIBC_2.14)(64bit)is needed by libnfsidmap-0.26-0.0.fc20.x86_64

提示说glibc需要2.14，rpm查到的glibc版本为2.12,故需升级glibc到2.14即可

下载文件后强制覆盖升级安装

rpm -Uvh glibc-2.14.1-6.x86_64.rpm --force--nodeps

rpm -Uvh glibc-common-2.14.1-6.x86_64.rpm--force --nodeps

2.[root@localhostadmin]# rpm -ivh libnfsidmap-0.26-0.0.fc20.x86_64.rpm

3.安装完portmap后启动无反应，vim/etc/sysconfig/network

将NETWORKING=no改为yes即可,portmap脚本就是检查“$NETWORKING”这个变量是通过source /etc/sysconfig/network来得到这个变量值的。

 

4.启动nfs报错

rpc.mountd: svc_tli_create: could not openconnection for udp6

处理：将IPV6开启

解决办法：

1 #service rpcbind restart

2 #service nfs start

5.[root@server /]# showmount -e

mount clntudp_create: RPC: Program notregistered

修改/etc/hosts把第二行注释拿掉

/etc/sysconfig/network-script/ifcfg-eth0中的IPV6INIT设置为yes

 

6.客户端测试时候无法使用 showmount命令，如果NFS正常，客户端直接挂载即可，不需使用showmount,如需测试使用showmount需在客户端安装如下软件即可，安装过程及相关问题处理如下：

[root@localhostPackages]# ls *showmount*

ls: cannot access *showmount*: No such fileor directory
