Centos5.8搭建NFS 服务器实例(三)

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

[root@58server1~]#uname-m
x86_64

[root@58server1~]#ifconfig

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
