Linux Enterprise Server Configuration scenario: Server for NFS

& 3.1 Introduction

NFS is the abbreviation of the network file system (receptacle http://www.aliyun.com/zixun/aggregation/19352.html ">file system") and is an integral part of distributed computing systems, Implementing remote file systems sharing and assembling on heterogeneous networks is no different from the user's point of view in these remote file system operations and local file systems. NFS, developed by Sun Microsystems (Sun Microsystem, Inc.), developed an NFS standard and was accepted by the IETF as a standard for file services (rfc1904,rfc1813). NFS is based on the client/server architecture, implemented via RPC (remote Procedure Call), and all NFS operations are performed by the RPC process. The NFS server exports the local directory to the remote NFS client, and the NFS client redirects the file operating system calls to the remote system. In Linux, the NFS service is usually implemented with KNFSD, a daemon that runs in the core space, and has a higher response performance than the NFS program with user space.

& 3.2 Resource requirements

&3.2.1 Required Package

RedHat 6.2 Server Installation

&3.2.2 Required configuration Files

/etc/exports system with the administrator configuration

& 3.3 Configuration Scheme

1./etc/exports

Description: NFS Main configuration file
Source file:
/home/weboa www.weboa.com.cn (rw)
# provide/home/weboa to www.weboa.com.cn access, access is readable and writable

& 3.4 Testing and management measures

1. Modify the configuration file to perform/etc/rc.d/init.d/nfs start

& 3.5 Summary

NFS (receptacle file System) is a protocol developed by Sun for file sharing on the network. NFS is easy to use, so it is widely used. However, because its authentication mechanism is based on IP address, it is vulnerable to attack.
Note that NFS is based on the RPC mechanism, so the Portmap service must be open.
