It is as shown in Figure 1 the flow chart of the method for server data sharing in one embodiment of the invention, this method can be with
Include the following steps S11-S14.
Multiple servers of data to be shared are divided into primary server and one or more from server by step S11.
In the cluster of multiple servers composition, it is sometimes desirable to share some data among multiple servers, here may be used
Multiple servers are divided into primary server and one or more from server.
Step S12 installs NFS service on primary server, and the configuration file for the NFS service installed on primary server
Middle configuration primary server shares to external catalogue, is able to access that the one or more of the catalogue is visited from server and accordingly
Ask parameter.
In this step, NFS service can be installed on primary server by yum, it needs to install two software packages,
That is, nfs-utils and rpcbind software package, wherein nfs-utils includes basic NFS order and monitoring programme；rpcbind
The connection of safe NFS RPC service is supported, for example, RPC is rpcbind in 6 system of Centos.
Step S13 is installed from server for one or more from each from server in server each
NFS service, and external catalogue is shared to using NFS service search primary server.
In this step, NFS service is installed from server each, may refer in step S12 on primary server
The scheme of NFS service is installed, that is, NFS service is installed each from server by yum, it needs to install two software packages,
That is, nfs-utils and rpcbind software package, wherein nfs-utils includes basic NFS order and monitoring programme；rpcbind
The connection of safe NFS RPC service is supported, for example, RPC is rpcbind in 6 system of Centos.
In addition, needing to start on primary server before sharing to external catalogue using NFS service search primary server
NFS service.Need first to enable rpcbind service before starting NFS service, because NFS will be registered to rpcbind.
Step S14, it is each from server execute carry order, by each specified directory carry from server to
Primary server shares to external catalogue, to realize primary server and each data sharing from server.
In embodiments of the present invention, by multiple servers of data to be shared be divided into primary server and it is one or more from
Server；Network File System NFS service is installed on the primary server, and described in installing on the primary server
The primary server is configured in the configuration file of NFS service to share to external catalogue, be able to access that the one of the catalogue
Or multiple parameter is accessed from server and accordingly；For one or more of from each from server in server,
Each NFS service is installed from server, and shares to external mesh using primary server described in the NFS service search
Record；Carry order is executed from server each, by each specified directory carry from server to the primary server
External catalogue is shared to, to realize the primary server and each data sharing from server.It can be seen that the present invention is real
It applies example and NFS service is installed on the server, the purpose of the data sharing between server is flexibly and effectively realized based on NFS service.
In alternative embodiment of the invention, the configuration file for the NFS service that above step S12 is installed on primary server
Can be/etc/exports, format is as follows:
directory(or file system)client1(option1,option2)client2(option1,
option2)
Here, file system (file system) refers to that NFS service needs to share to the catalogue of client；Client is
The host for referring to accessible NFS service in network, can be used IP, FQDN or DOMAIN, NETWORK.In the embodiment of the present invention
In, client here is mentioned above one or more from server.
(1) option is commonly used.There are several common options that can realize NFS to be customized, comprising:
Secure: this option is default option, it has used the connection of 1024 realization NFS in the ports TCP/IP below.
Specified insecure can disable this option.
Rw: this option allows NFS client computer to carry out read/write access.Default option is read-only.
Async: this option can improve performance, but restart if being not completely turned off NFS finger daemon
Nfs server, this may also will cause loss of data.
No_wdelay: delay is write in the closing of this option.If being provided with async, NFS ignores that this option.
Nohide: if as soon as a catalogue is mounted on another catalogue, then original catalogue is usually hidden
As concealing or looking like sky.This behavior is disabled, hide option need to be enabled.
No_subtree_check: this option closes subtree inspection, and subtree inspection can execute some peaces for being not desired to ignore
Full property inspection.Default option is to enable subtree inspection.
No_auth_nlm: this option can also be used as insecure_locks and specify, it tells NFS finger daemon not
Locking request is authenticated.If being concerned about safety issue it is necessary to avoid using this option.Default option is auth_
Nlm or secure_locks.
Mp (mountpoint=path): by explicitly stating that this option, NFS require catalogue derived from carry institute.
Fsid=num: this option usually all uses in the case where NFS fault recovery.
(2) user maps.By user's mapping in NFS, the mark of pseudo- or actual user and group can be assigned to one
The user that NFS volumes is being operated.This NFS user has the permissions for mapping permitted user and group.To NFS
Volume can provide certain safety and flexibility using a general user/group, without bringing many administrative loads.
In the file in the file system using NFS carry, the access of user usually can be all restricted, this is to say
User is to be accessed with the identity of anonymous to file, in the case of these user defaults only only to these files
Read right.This behavior is even more important for root user.However, actually there is such case really: it is desirable that user
With the file on the identity of root user or defined other users access Telefile.NFS allows specified access remote
The user of journey file can disable normal squash behavior by customer identification number (UID) and group identification number (GID).
User mapping option include:
Root_squash: this option does not allow root user to access NFS volumes on carry.
No_root_squash: this option allows root user to access NFS volumes come on carry.
All_squash: this option is highly useful for NFS volumes of public visit, it will limit all UID
And GID, only use anonymous.Default setting is no_all_squash.
Anonuid and anongid: anonymous UID and GID are modified as specific user and group account by the two options.
For example, master is configured in the configuration file/etc/exports for the NFS service that can be installed on primary server
Server shares to external catalogue, is able to access that the one or more of the catalogue accesses parameter from server and accordingly,
It is as follows:
vim/etc/exports
/media/testnfs/*.gdfs.edu.cn(rw,no_root_squash,no_all_squash,sync)
Wherein ,/media/testnfs/ is that primary server shares to external catalogue, is owned in the domain * .gdfs.edu.cn
Host can access the catalogue, and have access limit.
In alternative embodiment of the invention, after step s 12, exports order can be used, again the main clothes of carry
Configuration in the configuration file for the NFS service installed on business device.In the present embodiment ,/etc/ is had modified again after starting NFS service
Exports, without restarting the service, using exports order, specific exports order is as follows:
exports[-aruv]
Content in-a whole mount or umount file/etc/exports；
- r shared the content in mount file/etc/exports again；
- u umount catalogue；
Detailed information is output on screen by-v when export.
In alternative embodiment of the invention, outside is shared to using NFS service search primary server in step s 13
Catalogue executes order are as follows: showmout-e NFSSERVER_IP.
For example, showmount-e 192.168.28.220, wherein 192.168.28.220 is the IP of primary server
Location.
In alternative embodiment of the invention, carry order can be executed from server each in step S14, it will
Each specified directory carry to primary server from server shares to external catalogue, and carry mount order can be such that
Mount servername (or IP): share directory local mount directory.
For example, mount-t nfs 192.168.28.220:/media/testnfs//opt/testnfs/
Wherein, 192.168.28.220 is the IP address of primary server, and/media/testnfs/ shares to for primary server
External catalogue ,/opt/testnfs/ is the catalogue that carry is wanted from server.
After carry success, from server/opt/testnfs/ catalogue in the file and primary server that show/media/
The file shown in testnfs/ catalogue is consistent.Further, in primary server /media/testnfs/ catalogue in
Addition and delete file, from server /opt/testnfs/ catalogue in can be with simultaneous display.In addition, from server
In /opt/testnfs/ catalogue in add or delete file, primary server /media/testnfs/ catalogue in be also can
With simultaneous display.

Connection.
Step S23, configuration primary server shares to external in the configuration file for the NFS service installed on primary server
Catalogue is able to access that the one or more of the catalogue accesses parameter from server and accordingly.
In this step, for example, editor configuration file vim/etc/exports
/media/testnfs/*.gdfs.edu.cn(rw,no_root_squash,no_all_squash,sync)
Wherein ,/media/testnfs/ is that primary server shares to external catalogue, is owned in the domain * .gdfs.edu.cn
Host can access the catalogue, and have access limit.
Step S24, using exports order, in the configuration file for the NFS service installed on carry primary server again
Configuration.
In this step ,/etc/exports is had modified again after starting NFS service, without restarting the service, used
Exports order, such as exportfs-r.
Step S25 is installed from server for one or more from each from server in server each
NFS service, and external catalogue is shared to using NFS service search primary server.
For example, showmount-e 192.168.28.220, wherein 192.168.28.220 is the IP of primary server
Location.
Step S26, each execution carry order from server, by each specified directory carry from server to master
Server shares to external catalogue, to realize primary server and each data sharing from server.
In this step, carry mount order can be such that
Mount servername (or IP): share directory local mount directory.
For example, mount-t nfs 192.168.28.220:/media/testnfs//opt/testnfs/
Wherein, 192.168.28.220 is the IP address of primary server, and/media/testnfs/ shares to for primary server
External catalogue ,/opt/testnfs/ is the catalogue that carry is wanted from server.
After carry success, from server/opt/testnfs/ catalogue in the file and primary server that show/media/
The file shown in testnfs/ catalogue is consistent.Further, in primary server /media/testnfs/ catalogue in
Addition and delete file, from server /opt/testnfs/ catalogue in can be with simultaneous display.In addition, from server
In /opt/testnfs/ catalogue in add or delete file, primary server /media/testnfs/ catalogue in be also can
