NFS server configuration in Linux

The Network File System (NFS) configured on the NFS server in Linux is a mechanism to mount the partitions (directories) on the remote host to the local device through the network, with support for the network file system, you can operate on the shared partition (directory) of the remote host on the local system just like operating on the local partition. Similar to Windows shared directory. NFS installation is very simple. In Linux2.6, only three software packages are required, and usually installed as the system's default package. Nfs-utils-* (2) and system-config-nfs-* (1) 1. Check whether the system has NFS rpm-qa | reap nfs 2. the NFS server configuration file for NFS service is/etc/exports. This file is the main NFS configuration file, however, the system does not have a default value. You may need to manually create it using vim and then write the configuration content in the file. Vim etc/exports: Add a directory and access permission for other computers. Example:/nfs 218.197.21. * (rw, sync, no_root_squash)/nfs: Directory 218.197.21 that allows access from other computers. *: The Client IP address that is allowed to access the directory rw: Read and Write Permissions sync: synchronize data into the memory buffer and disk, which is less efficient, but can ensure data consistency (async: store data in the memory buffer before writing data to the disk if necessary.) no_root_squash: the root user of the client has the write permission on the directory. 3. Run the command: service nfs restart to restart the NFS service.
