It is illustrated in figure 1 the flow chart of the method for server data sharing in one embodiment of the invention, the method can be with
Comprise the following steps S11-S14.
Step S11, by multiple servers of data to be shared be divided into master server and one or more from server.
Multiple server groups into cluster in, it is sometimes desirable among multiple servers share some data, here may be used
With by multiple servers be divided into master server and one or more from server.
Step S12, installs NFS services, and the configuration file of the NFS services installed on master server on master server
Catalogue that middle configuration master server shares to outside, one or more for being able to access that the catalogue from server and corresponding are visited
Ask parameter.
In this step, NFS services can be installed on master server by yum, it needs to install two software kits,
That is, nfs-utils and rpcbind software kits, wherein, nfs-utils includes basic NFS orders and monitoring programme；rpcbind
The connection of safe NFS RPC services is supported, for example, RPC is rpcbind in 6 systems of Centos.
Step S13, for one or more each from server are from server, installs from server at each
NFS is serviced, and the catalogue of outside is shared to using NFS service search master servers.
In this step, NFS services are installed from server at each, may refer in step S12 on master server
The scheme of NFS services is installed, i.e. NFS services are installed from server at each by yum, it needs to install two software kits,
That is, nfs-utils and rpcbind software kits, wherein, nfs-utils includes basic NFS orders and monitoring programme；rpcbind
The connection of safe NFS RPC services is supported, for example, RPC is rpcbind in 6 systems of Centos.
Additionally, before the catalogue of outside is shared to using NFS service search master servers, needing to start on master server
NFS service.Needed first to enable rpcbind services before NFS services are started, because NFS will be registered to rpcbind.
Step S14, performs carry order from server at each, the assigned catalogue carry by each from server to
Master server shares to the catalogue of outside, to realize master server with each from the data sharing of server.
In embodiments of the present invention, by multiple servers of data to be shared be divided into master server and one or more from
Server；The service of NFS NFS is installed on the master server, and described in installing on the master server
Configure the master server to share to the catalogue of outside, be able to access that the one of the catalogue in the configuration file of NFS services
Or multiple access from server and accordingly parameter；For one or more of each from server are from server,
NFS services are installed from server at each, and the mesh of outside is shared to using master server described in the NFS service search
Record；Carry order is performed from server at each, the assigned catalogue carry by each from server is to the master server
The catalogue of outside is shared to, to realize the master server with each from the data sharing of server.As can be seen here, the present invention is real
Apply example and NFS services are installed on the server, the purpose of the data sharing between server is flexibly and effectively realized based on NFS services.
In the alternative embodiment of the present invention, the configuration file of the NFS services that above step S12 is installed on master server
Can be as follows for/etc/exports, its form：
directory(or file system)client1(option1,option2)client2(option1,
option2)
Here, file system (file system) refer to that NFS services need to share to the catalogue of client；Client is
The main frame of NFS services can be accessed in referring to network, it is possible to use IP, FQDN or DOMAIN, NETWORK.In the embodiment of the present invention
In, client here for it is mentioned above one or more from server.
(1) commonly use option.There are several conventional options realize being customized to NFS, including：
secure：This option is default option, and it realizes the connection of NFS using less than 1024 TCP/IP ports.
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 with improvement performance, but can be restarted if being not completely turned off NFS finger daemons
Nfs server, this is likely to cause loss of data.
no_wdelay：This option is closed and writes time delay.If being provided with async, then NFS ignores that this option.
nohide：If a catalogue is mounted on another catalogue, then catalogue originally is generally just hidden
Conceal or look like as sky.This behavior is disabled, hide options need to be enabled.
no_subtree_check：This option closes subtree inspection, and subtree inspection can perform the peace that some are not desired to ignore
Full property inspection.Default option is to enable subtree inspection.
no_auth_nlm：This option can also be specified as insecure_locks, and it tells NFS finger daemons 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 this option, NFS requires catalogue derived from carry institute.
Fsid=num：This option is generally used all in the case of NFS fault recoveries.
(2) user's mapping.Mapped by the user in NFS, the mark of pseudo- or actual user and group can be assigned to one
The user that NFS volume is being operated.User and the permissions of group that this NFS user has mapping allowed.To NFS
Volume can provide certain safety and motility using a general user/group, without bringing many administrative loads.
During file in the file system using NFS carries, the access of user generally can all be restricted, in other words
User is with the identity of anonymous conducting interviews to file, in the case of these user defaults to these files only only
Read right.This behavior is even more important for root user.However, actually there is really such case：Wish user
File on Telefile is accessed with the identity of root user or defined other users.NFS is allowed to specify and is accessed remote
The user of journey file, by customer identification number (UID) and group identification number (GID), can disable normal squash behaviors.
The option of user's mapping includes：
root_squash：This option does not allow root user to access NFS volume on carry.
no_root_squash：This option allows root user to access NFS volume come on carry.
all_squash：This option is highly useful for NFS volume of public visit, and it can limit all of 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, configuration master in the configuration file/etc/exports of the NFS services that can be installed on master server
Catalogue that server shares to outside, one or more for being able to access that the catalogue access 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/ shares to the catalogue of outside for master server, owns in * .gdfs.edu.cn domains
Main frame can access the catalogue, and have access limit.
In the alternative embodiment of the present invention, after step s 12, it is possible to use exports orders, main clothes of carry again
Configuration in the configuration file of the NFS services installed on business device.In the present embodiment ,/etc/ is have modified again after starting NFS services
Exports, without restarting the service, using exports orders, concrete exports orders are as follows：
exports[-aruv]
Content in-a whole mount or umount files/etc/exports；
- r shared contents again in mount files/etc/exports；
- u umount catalogues；
- v when export, by detailed information output to screen.
In the alternative embodiment of the present invention, outside is shared to using NFS service search master servers in step s 13
Catalogue, performing order is：showmout-e NFSSERVER_IP.
For example, showmount-e 192.168.28.220, wherein, IP ground of the 192.168.28.220 for master server
Location.
In the alternative embodiment of the present invention, carry order can be performed from server at each in step S14, will
Each assigned catalogue carry to master server from server shares to the catalogue of outside, and carry mount orders can be as follows：
mount servername(or IP)：The local mount directory of share directory.
For example, mount-t nfs 192.168.28.220:/media/testnfs//opt/testnfs/
Wherein, IP address of the 192.168.28.220 for master server ,/media/testnfs/ are shared to for master server
Outside catalogue ,/opt/testnfs/ is the catalogue that carry is wanted from server.
After carry success, from server/opt/testnfs/ catalogues in the file and master server that show/media/
The file shown in testnfs/ catalogues is consistent.Further, in master server /media/testnfs/ catalogues in
Addition and delete file, from server /opt/testnfs/ catalogues in can be with simultaneous display.Additionally, from server
In /opt/testnfs/ catalogues in addition or delete file, master server /media/testnfs/ catalogues in be also can

NFS is serviced, and the catalogue of outside is shared to using NFS service search master servers.
For example, showmount-e 192.168.28.220, wherein, IP ground of the 192.168.28.220 for master server
Location.
Step S26, each performs carry order from server, and the assigned catalogue carry by each from server is to master
Server shares to the catalogue of outside, to realize master server with each from the data sharing of server.
In this step, carry mount orders can be as follows：
mount servername(or IP)：The local mount directory of share directory.
For example, mount-t nfs 192.168.28.220:/media/testnfs//opt/testnfs/
Wherein, IP address of the 192.168.28.220 for master server ,/media/testnfs/ are shared to for master server
Outside catalogue ,/opt/testnfs/ is the catalogue that carry is wanted from server.
After carry success, from server/opt/testnfs/ catalogues in the file and master server that show/media/
The file shown in testnfs/ catalogues is consistent.Further, in master server /media/testnfs/ catalogues in
Addition and delete file, from server /opt/testnfs/ catalogues in can be with simultaneous display.Additionally, from server
In /opt/testnfs/ catalogues in addition or delete file, master server /media/testnfs/ catalogues in be also can
