服务器评测
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
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.

- /etc/init.d/nfs start
