Gentoo Linux下配置NFS（網絡文件系統）

主機：Gentoo Linux 11.2

內核：Linux 3.0.6

1、內核編譯配置

編譯內核配置如下，選中NFS服務器支持

2、用於空間軟件准備

命令安裝nfs-utils

1. emerge -av nfs-utils  

按自己的要求改寫

/home/user/shared 192.168.0.3(async,rw,no_subtree_check)

/home/user/shared2 192.168.0.0/255.255.0.0(async,rw,no_subtree_check)

/mnt/portage 192.168.0.0/16(async,no_subtree_check,rw,no_root_squash)

而括號中的參數含義如下：

• rw - Allow read and write access
• ro - Allow read only access - no write access
• async - Reply to requests before data has been committed to the file system. This improves performance, but increases the risk of data loss in the event of a server crash.
• no_subtree_check - Disable subtree checking. The technical details are in the man page, but essentially it's recommended for read/write filesystems where files change frequently, such as /home. If you disable subtree checking and export something that's not the root of a filesystem, it's possible a client could access a file outside the exported directory, however.
• root_squash - Prevent the client creating files owned by root - instead they will be owned by the anonymous uid/gid (user id / group id, see man page for details).
• no_root_squash - Turn off root squashing. Mostly used on diskless clients.
• all_squash - Map all uids/gids to the anonymous user. This means that all files written to this filesystem will be owned by the same user.

1. /etc/init.d/nfs start
