　　Network File System (NFS)是可以用来在网络上访问文件的系统。它大部分用在UNIX系统上，但是你也可以在Linux和Windows上使用它。在OpenSolaris的NFS默认版本是4,这个服务通过SMF管理，这意味着你需要使用svcs和svcadm命令去检查、启用、禁用或者重起它。

　　开始让我们检查一下NFS服务是否在我的系统上启动了： 

root# svcs network/nfs/server
STATE          STIME    FMRI
disabled      9:30:35 svc:/network/nfs/server:default
root#
　　啊哈，它是禁用的。Solaris 9上NFS是随系统启动的，这里不是。让我首先尝试启动它：
root# svcadm enable network/nfs/server
root# svcs network/nfs/server
STATE          STIME    FMRI
offline      10:11:56 svc:/network/nfs/server:default
root#
　　Offline－这意味着服务实例被启用，但是服务仍然没有运行。这个服务需要其它服务，大概他们根本没有运行，
那就是它没有启动的原因：
root# svcs -d svc:/network/nfs/server:default
STATE          STIME    FMRI
disabled      9:30:35 svc:/network/rpc/keyserv:default
disabled      9:30:35 svc:/network/nfs/mapid:default
disabled      10:26:56 svc:/network/nfs/nlockmgr:default
online          9:30:52 svc:/milestone/network:default
online          9:31:08 svc:/system/filesystem/local:default
online          9:31:10 svc:/network/shares/group:zfs
online          9:31:10 svc:/network/shares/group:default
online          9:31:26 svc:/network/rpc/gss:default
online         10:26:56 svc:/network/rpc/bind:default
　　需要的keyserv、mapid和nlockmgr没有运行，我将要启动它们。
root# svcadm enable svc:/network/nfs/mapid:default
root# svcadm enable svc:/network/rpc/keyserv:default
root# svcadm enable svc:/network/nfs/nlockmgr:default

root# svcs -d svc:/network/nfs/server:default
STATE          STIME    FMRI
online          9:30:52 svc:/milestone/network:default
online          9:31:08 svc:/system/filesystem/local:default
online          9:31:10 svc:/network/shares/group:zfs
online          9:31:10 svc:/network/shares/group:default
online          9:31:26 svc:/network/rpc/gss:default
online         10:26:56 svc:/network/nfs/nlockmgr:default
online         10:26:56 svc:/network/rpc/bind:default
online         10:33:11 svc:/network/nfs/mapid:default
maintenance  10:33:20 svc:/network/rpc/keyserv:default
root#
　　Keyserv在maintenance模式：这意味着服务实例遇到了错误，管理员必须要解决。让我们看看日志文件：
root# cd /var/svc/log
root# tail network-rpc-keyserv:default.log
[ Jul 11 13:59:05 Stopping because service disabled. ]
[ Jul 11 13:59:05 Executing stop method (:kill) ]
[ Jul 11 13:59:15 Executing start method (“/usr/sbin/keyserv”) ]
[ Jul 11 13:59:15 Method “start” exited with status 96 ]

　　我在网络搜索了一下，问题好像是服务 network/nis/client被禁用了：

root# svcadm enable network/nis/client
root# svcs network/nis/client
STATE          STIME    FMRI
maintenance  11:04:44 svc:/network/nis/client:default
root# cat network-nis-client:default.log
[ Jul 11 13:59:05 Disabled. ]
[ Jul 11 13:59:05 Rereading configuration. ]
[ Jul 17 11:04:44 Enabled. ]
[ Jul 17 11:04:44 Executing start method (”/lib/svc/method/yp”) ]
/lib/svc/method/yp: domainname not set
[ Jul 17 11:04:44 Method “start” exited with status 96 ]
root#
root#
root#
root# ls -l /etc/defaultdomain
/etc/defaultdomain: No such file or directory
root#
root# cat > /etc/defaultdomain
ww300.siemens.net
^D
root#
root#
root# domainname `cat /etc/defaultdomain`
root#
root#
root# # add your NIS server in /etc/hosts
root# echo “163.242.239.20  PrimaryDNS PrimaryWINSserver” >> /etc/hosts
root#
root#
root# ypinit -c

In order for NIS to operate sucessfully, we have to construct a list of the
NIS servers.  Please continue to add the names for YP servers in order of
preference, one per line.  When you are done with the list, type a
or a return on a line by itself.
        next host to add:  163.242.239.20
        next host to add:

The current list of yp servers looks like this:

163.242.239.20

Is this correct?  [y/n: y]  y
root#
root# svcadm enable nis/client
root# svcs  nis/client
STATE          STIME    FMRI
online        11:34:32 svc:/network/nis/client:default
root#
　　 现在需要做的就是启动keyserv然后启动nfs服务器：
root# svcadm clear svc:/network/rpc/keyserv:default
root# svcs svc:/network/rpc/keyserv:default
STATE          STIME    FMRI
online        11:37:44 svc:/network/rpc/keyserv:default
root#
root#
root# svcadm enable nfs/server
root# svcs nfs/server
STATE          STIME    FMRI
online*      11:38:05 svc:/network/nfs/server:default
root#
root# svcs nfs/server
STATE          STIME    FMRI
disabled      11:38:11 svc:/network/nfs/server:default
root#
root# tail network-nfs-server:default.log
[ Jul 17 11:38:05 Stopping because service disabled. ]
[ Jul 17 11:38:05 Executing stop method (”/lib/svc/method/nfs-server stop 117?) ]
[ Jul 17 11:38:10 Method “stop” exited with status 0 ]
[ Jul 17 11:40:01 Enabled. ]
[ Jul 17 11:40:01 Executing start method (”/lib/svc/method/nfs-server start”) ]
No NFS filesystems are shared
 　噢，没有共享文件系统，好，让我修正它：
root# share /export/home/
root# svcadm enable nfs/server
root# svcs nfs/server
STATE          STIME    FMRI
online       11:45:07 svc:/network/nfs/server:default
root#
 　确保文件系统被正确地输出，通过运行dfshares或者showmount -e <UNIX主机的IP地址>
root# showmount -e localhost
export list for localhost:
/export/home (everyone)
root#
　　为了系统重起后共享命令有效，你必须把它们添加到/etc/dfs/dsftab文件中。现在NFS服务器设置好了。
如果一个客户想使用它，就必须把它挂载上，在UNIX系统类似如下：
 root# mount server_name:/shared/filesystem /local_directory
　　如果客户端是Windows，你就必须下载并安装 Windows Services for UNIX。更好的选择是使用一些
第三方软件例如Jftp。
