Centos5.8搭建NFS 服务器实例：
服务器系统 |
角色 |
IP |
CentOS-5.8-111-server1 |
NFS服务器端 |
192.168.1.111 |
CentOS-5.8-119-client |
NFS客户端 |
192.168.1.119 |
共享CentOS-5.8-111-server1中/data/bbs目录，使192.168.1.1 IP段所有主机都可以访问
配置服务端：
首先创建实验环境目录
[root@58server1~]#mkdir/data/bbs�Cp [root@58server1bbs]#chown-Rnfsnobody.nfsnobody/data/bbs [root@58server1bbs]#ls-ld/data/bbs drwxr-xr-x.2nfsnobodynfsnobody4096Jan1917:08/data/bbs
检查服务器系统信息
操本系统版本信息：
[root@58server1~]#cat/etc/redhat-release CentOSrelease5.8(Final) [root@58server1~]#uname-r 2.6.18-308.el5 [root@58server1~]#uname-n 58server1 [root@58server1~]#uname-a Linux58server12.6.18-308.el5#1SMPTueFeb2120:06:06EST2012x86_64x86_64x86_64GNU/Linux [root@58server1~]#uname-m x86_64 [root@58server1~]#ifconfig eth0Linkencap:EthernetHWaddr00:0C:29:92:A2:4A inetaddr:192.168.1.111Bcast:192.168.1.255Mask:255.255.255.0 UPBROADCASTRUNNINGMULTICASTMTU:1500Metric:1 RXpackets:1284errors:0dropped:0overruns:0frame:0 TXpackets:109errors:0dropped:0overruns:0carrier:0 collisions:0txqueuelen:1000 RXbytes:81933(80.0KiB)TXbytes:12330(12.0KiB) loLinkencap:LocalLoopback inetaddr:127.0.0.1Mask:255.0.0.0 UPLOOPBACKRUNNINGMTU:16436Metric:1 RXpackets:2errors:0dropped:0overruns:0frame:0 TXpackets:2errors:0dropped:0overruns:0carrier:0 collisions:0txqueuelen:0 RXbytes:100(100.0b)TXbytes:100(100.0b)
分别查看服务端的相关信息，如ip,主机名等等
检查NFS软件
[root@58server1~]#rpm-aq|egrep"nfs-utils|portmap" nfs-utils-1.0.9-60.el5 portmap-4.0-65.2.2.1 nfs-utils-lib-1.0.8-7.9.el5
查看服务器的centos中5.8 portmap、6.4 rpcbind服务有没有启动和检查nfs、启动nfs
[root@58server1~]#/etc/init.d/portmapstatus portmapisstopped [root@58server1~]#/etc/init.d/nfsstatus rpc.mountdisstopped nfsdisstopped rpc.rquotadisstopped [root@58server1~]#/etc/init.d/portmapstart Startingportmap:[OK] [root@58server1~]#/etc/init.d/nfsstart StartingNFSservices:[OK] StartingNFSquotas:[OK] StartingNFSdaemon:[OK] StartingNFSmountd:[OK] StartingRPCidmapd:[OK] [root@58server1~]#/etc/init.d/portmapstatus portmap(pid25698)isrunning... [root@58server1~]#/etc/init.d/nfsstatus rpc.mountd(pid25766)isrunning... nfsd(pid2576325762257612576025759257582575725756)isrunning... rpc.rquotad(pid25729)isrunning...
配置portmap（Centos6.4下为rpcbind）及NFS服务开机自启动
[root@58server1~]#echo"#NFSserverstartatdingjianto2014.01.09">>/etc/rc.local [root@58server1~]#echo"/etc/init.d/portmapstart">>/etc/rc.local [root@58server1~]#echo"/etc/init.d/nfsstart">>/etc/rc.local [root@58server1~]#tail-3/etc/rc.local #NFSserverstartatdingjianto2014.01.09 /etc/init.d/portmapstart /etc/init.d/nfsstart
配置NFS服务
[root@58server1~]#echo"/data/bbs192.168.1.1/24(rw,sync)">>/etc/exports [root@58server1~]#tail-1/etc/exports /data/bbs192.168.1.1/24(rw,sync)
六、/etc/init.d/nfs reload 或exportfs -rv进行nfs重新加载
[root@58server1~]#/etc/init.d/nfsreload [root@58server1~]#exportfs-rv exporting192.168.1.1/24:/data/bbs
r意思是重新挂载
v意思是显示过程
七、showmount -e localhost show一下自己，看服务端有没有配置好
[root@58server1bbs]#showmount-elocalhost Exportlistforlocalhost: /data/bbs192.168.1.1/24
配置客户端：
检查系统环境
[root@58client~]#cat/etc/redhat-release CentOSrelease5.8(Final) [root@58client~]#uname-n 58client [root@58client~]#uname-r 2.6.18-308.el5 [root@58client~]#uname-a Linux58client2.6.18-308.el5#1SMPTueFeb2120:06:06EST2012x86_64x86_64x86_64GNU/Linux [root@58client~]#uname-m x86_64
2.检查和启动portmap(6.4rpcbind)服务(注意无需启动NFS服务)
[root@58client~]#rpm-aq|grepportmap portmap-4.0-65.2.2.1 [root@58client~]#/etc/init.d/portmapstatus portmapisstopped [root@58client~]#/etc/init.d/portmapstart Startingportmap:[OK] [root@58client~]#/etc/init.d/portmapstatus portmap(pid22949)isrunning...
3.把portmap加入开机自启动
[root@58client~]#echo"#NFSClientstartatdingjianto2014.01.19">>/etc/rc.local [root@58client~]#echo"/etc/init.d/portmapstart">>/etc/rc.local [root@58client~]#tail-2/etc/rc.local #NFSClientstartatdingjianto2014.01.19 /etc/init.d/portmapstart
4扫描NFS服务器的文件共享例表
[root@58client~]#showmount-e192.168.1.111 Exportlistfor192.168.1.111: /data/bbs192.168.1.1/24
5.挂载NFS服务器共享目录到本地系统
[root@58client~]#mount-tnfs192.168.1.111:/data/bbs/mnt [root@58client~]#df Filesystem1K-blocksUsedAvailableUse%Mountedon /dev/sda31798134021246481492854013%/ /dev/sda1295561168422634597%/boot tmpfs601360601360%/dev/shm 192.168.1.111:/data/bbs1798134421178241493537613%/mnt
6.配置开机自动挂载NFS共享目录
[root@58client~]#echo"mount-tnfs192.168.1.111:/data/bbs/mnt">>/etc/rc.local [root@58client~]#tail-1/etc/rc.local mount-tnfs192.168.1.111/data/bbs/mnt
7.测试数据
[root@58server1~]#cd/data/bbs [root@58server1bbs]#touchaa [root@58client~]#ls/mnt aa
提示：1.NFS服务端/var/lib/nfs/rmtab这个文件可以查看挂载的信息
/var/lib/nfs/xtab
2.配置NFS服务端后，不用重启NFS服务，只要使用exportfs -rv或/etc/init.d/nfs reload重新加载就可以了
3.rpc主程序Centos5.8下为portmap 、Centos6.4下为rpcbind
4.NFS共享目录不要授权于777权限，可以改所属主和组为nfsnobody，因为nfsnobody权限不是很大，也不能登陆
rpcinfo�Cp localhost 查看本机的rpcinfo对外提供哪些端口
