Centos6.4搭建NFS 服务器实例(四)

Centos6.4搭建NFS 服务器实例：

服务器系统	角色	IP
CentOS-64-121-server1	NFS服务器端	192.168.1.121
CentOS-64-129-client	NFS客户端	192.168.1.129

共享CentOS-64-121-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@64server1~]#mkdir/data/bbs�Cp
[root@64server1bbs]#chown-Rnfsnobody.nfsnobody/data/bbs
[root@64server1bbs]#ls-ld/data/bbs
drwxr-xr-x.2nfsnobodynfsnobody4096Jan1917:08/data/bbs

检查服务器系统信息

301

[root@64server1~]#cat/etc/redhat-release
CentOSrelease6.4(Final)
[root@64server1~]#uname-n

[root@64server1~]#uname-r

分别查看服务端的相关信息，如ip,主机名等等

检查NFS软件

301

[root@64server1~]#rpm-aq|egrep"nfs-utils|rpcbind"
nfs-utils-1.2.3-36.el6.x86_64
nfs-utils-lib-1.1.5-6.el6.x86_64
rpcbind-0.2.0-11.el6.x86_64

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

301

[root@64server1~]#/etc/init.d/rpcbindstatus
rpcbind(pid1100)isrunning...
[root@64server1~]#/etc/init.d/nfsstatus
rpc.svcgssdisstopped
rpc.mountdisstopped

[root@64server1~]#/etc/init.d/nfsstatus

nfsd(pid16711670166916681667166616651664)isrunning...
rpc.rquotad(pid1602)isrunning...

配置NFS及portmap（Centos6.4下为rpcbind）服务开机自启动

301

[root@64server1~]#echo"#NFS6.4Serverstartatdingjianto2014.01.19">>/etc/rc.local
[root@64server1~]#echo"/etc/init.d/rpcbindstart">>/etc/rc.local
[root@64server1~]#echo"/etc/init.d/nfsstart">>/etc/rc.local
[root@64server1~]#tail-3/etc/rc.local
#NFS6.4Serverstartatdingjianto2014.01.19
/etc/init.d/rpcbindstart
/etc/init.d/nfsstart

配置NFS服务

301

[root@64server1~]#echo"#NFSshared/data/bbs2014.01.19">>/etc/exports
[root@64server1~]#echo"/data/bbs/192.168.1.1/24(rw,sync)">>/etc/exports
[root@64server1~]#tail-2/etc/exports
#NFSshared/data/bbs2014.01.19
/data/bbs/192.168.1.1/24(rw,sync)

六、/etc/init.d/nfs reload 或exportfs -rv进行nfs重新加载

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

八、授权nfsnobody于/data/bbs 让客户端挂载后可写可读

[root@64server1~]#chownnfsnobody:nfsnobody/data/bbs-R
[root@64server1~]#ls-ld/data/bbs
drwxr-xr-x.2nfsnobodynfsnobody4096Feb1618:30/data/bbs

客户端配置：

检查系统环境

[root@64client~]#cat/etc/redhat-release
CentOSrelease6.4(Final)
[root@64client~]#uname-a
Linux64client2.6.32-358.el6.x86_64#1SMPFriFeb2200:31:26UTC2013x86_64x86_64x86_64GNU/Linux
[root@64client~]#uname-n
64client
[root@64client~]#uname-r
2.6.32-358.el6.x86_64
[root@64client~]#uname-m
x86_64

2.检查和启动rpcbind(Centos5.8为portmap)服务(注意无需启动NFS服务)

[root@64client~]#rpm-aq|greprpcbind
rpcbind-0.2.0-11.el6.x86_64
[root@64client~]#/etc/init.d/rpcbindstatus
rpcbind(pid1115)isrunning...

3.把rpcbind加入开机自启动

[root@64client~]#echo"#NFSClientstartatdingjian2014.01.19">>/etc/rc.local
[root@64client~]#echo"/etc/init.d/rpcbindstart">>/etc/rc.local
[root@64client~]#tail-2/etc/rc.local
#NFSClientstartatdingjian2014.01.19
/etc/init.d/rpcbindstart

4扫描NFS服务器的文件共享例表

[root@64client~]#showmount-e192.168.1.121
Exportlistfor192.168.1.121:
/data/bbs192.168.1.1/24

5.挂载NFS服务器共享目录到本地系统

[root@64client~]#mount-tnfs192.168.1.121:/data/bbs/mnt
[root@64client~]#df
Filesystem1K-blocksUsedAvailableUse%Mountedon
/dev/sda3183755481511476159306489%/
tmpfs11818801181880%/dev/shm
/dev/sda11983372856815952916%/boot
192.168.1.121:/data/bbs
183755521503872159382409%/mnt

6.配置开机自动挂载NFS共享目录

[root@64client~]#echo"mount-tnfs192.168.1.121:/data/bbs/mnt">>/etc/rc.local
[root@64client~]#tail-3/etc/rc.local
#NFSClientstartatdingjian2014.01.19
/etc/init.d/rpcbindstart
mount-tnfs192.168.1.121:/data/bbs/mnt

7.测试数据

[root@64server1~]#cd/data/bbs
[root@64server1bbs]#touchaa

[root@64client~]#ls/mnt
aa

提示: 1.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

2.rpc主程序Centos5.8下为portmap 、Centos6.4下为rpcbind

3.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
