主机:Gentoo Linux 11.2
内核:Linux 3.0.6
1、内核编译配置
编译内核配置如下,选中NFS服务器支持
2、用于空间软件准备
命令安装nfs-utils
[Java]
emerge -av nfs-utils 3、配置NFS用户目录及其权限在/etc/exports下按自己的要求改写
/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)而括号中的参数含义如下:
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.3、启动NFS服务
[cpp]
/etc/init.d/nfs start 在开发板上挂载主机目录成功。
