Specific embodiment
The preferred embodiments of the present invention are illustrated below in conjunction with accompanying drawing, it will be appreciated that preferred reality described herein
Apply example and be merely to illustrate and explain the present invention, be not intended to limit the present invention.
The flow chart of the method for shared storage device in one embodiment of the invention is illustrated in figure 1, the method can include
Following steps S11-S13.
Step S11, installs iscsi services at server, using the tgtd modes in iscsi services come configuration server
The storage device to be shared at place.
In this step, scsi-target-utils software kits can be installed at server, to install iscsi services,
For example, it is yum-y install scsi-target-utils to install code.
Step S12, installs iscsi services at the client, to be shared is deposited using what iscsi serviced at carry server
Storage equipment.
In this step, iscsi-initiator-utils software kits can be installed at client, to install iscsi
Service, for example, installation code is yum install iscsi-initiator-utils.
Step S13, shares the storage device to be shared at the server of carry at client.
In this step, storage device to be shared that can be at the server at client to carry performs corresponding
The operation such as sharing operation, such as subregion, formatting, data storage, reading data.
In embodiments of the present invention, iscsi services are installed at server, using the tgtd side in iscsi services
Formula is configuring the storage device to be shared at the server;Iscsi services are installed, using the iscsi at client
Storage device to be shared at server described in service carry;Share at the client at the server of carry
Storage device to be shared.As can be seen here, the embodiment of the present invention can realize the purpose of neatly shared storage device.
Using the tgtd modes in iscsi services come the storage to be shared at configuration server in above step S11
Equipment, embodiments provides a kind of optional scheme, and the program may comprise steps of A1-A3.
Step A1, arranges one or more subregions at server.
In this step, it is, for example possible to use new subregion fdisk/dev/sda on disk at server, creates one
Individual/dev/sda5 subregions, size is 2G, after establishment, loads new partition information.
Step A2, configures one or more subregions as storage to be shared using the tgtd modes in iscsi services
Equipment.
Step A3, storage device opening to be shared is conducted interviews to client.
In the alternative embodiment of the present invention, treating altogether at carry server is serviced using iscsi in above step S12
Before the storage device enjoyed, can to create account number and password at the server, and then arrange at client using account number and
Password login server.So, client can adopt account number and password login server, and then service carry using iscsi
Storage device to be shared at server.
The method that the shared storage device of the present invention is discussed in detail below by a specific embodiment realizes process.At this
In embodiment, IP at server end is 192.168.0.83/24, and client ip is 192.168.0.84/24.
The flow chart of the method for shared storage device in another embodiment of the present invention is illustrated in figure 2, the method can be wrapped
Include following steps S21-S27.
Step S21, installs scsi-target-utils software kits at server, to install iscsi services.
In this step, it can be yum-y install scsi-target-utils to install code.
Service tgtd start## start service
Chkconfig tgtd on## allow its start automatic
Verify whether to successfully start up service
Netstat-tnlp | grep 3260#iscsi service defaults use 3260 ports
Step S22, arranges one or more subregions at server.
In this step, it is, for example possible to use new subregion fdisk/dev/sda on disk at server, creates one
Individual/dev/sda5 subregions, size is 2G, after establishment, loads new partition information.
Step S23, configures one or more subregions as storage to be shared using the tgtd modes in iscsi services
Equipment.
In this step, a target, i.e. tgtadm--lld iscsi--op new--mode is created first
target--tid 1-T iqn.2010-08.com.example.ts1:disk1;
Secondly, show the target, i.e. tgtadm--lld iscsi--op show--mode target--tid for creating
1;
Subsequently, create a LUN, number is 1, the storage device of addition be just created /dev/sda5, i.e.,
tgtadm--lld iscsi--op new--mode logicalunit--tid 1--lun 1-b/dev/sda5。
Step S24, storage device opening to be shared is conducted interviews to client.
In this step, the target of establishment can be opened and is conducted interviews to the main frame of the network segment specified, i.e.,
tgtadm--lld iscsi--op bind--mode target--tid 1-I 192.168.0.0/24。
Step S25, installs iscsi-initiator-utils software kits at client, to install iscsi services.
In this step, it can be yum install iscsi-initiator-utils, echo to install code "
InitiatorAlias=initiator1 ">>/etc/iscsi/initiatorname.iscsi.
Step S26, services the storage device to be shared at carry server using iscsi.
In this step, service can be started first, and adds start automatic ranks, i.e.,:
service iscsi start chkconfig iscsi on
Secondly, the shared information of server end storage device is checked, i.e.,:iscsiadm-m discovery-t
sendtargets-p 192.168.0.83
Subsequently, the shared storage device of carry, i.e.,:iscsiadm-m node-T iqn.2011-
09.com.example.ts1:disk1-p 192.168.0.83:3260-l
Can be checking the equipment of carry, i.e. fdisk l using fdisk-l orders after carry.
Step S27, shares the storage device to be shared at the server of carry at client.
In this step, storage device to be shared that can be at the server at client to carry performs corresponding
The operation such as sharing operation, such as subregion, formatting, data storage, reading data.
In the alternative embodiment of the present invention, it is possible to achieve the one direction login authentication of iscsi:
(1) account number redhat, setting code redhat are created in server end, and the authority for accessing certain tid is authorized for which,
I.e.:
tgtadm--lld iscsi--op new--mode account--user redhat--password redhat
Tgtadm--lld iscsi--op show--mode account## check establishment user
(2) in client-side editing initiator end master configuration file, configure client and log in the account number used during target
And password, i.e.,:vim/etc/iscsi/iscsid.conf
Modification result is as follows:
Node.session.auth.authmethod=CHAP
Node.session.auth.username=redhat
Node.session.auth.password=redhat
If not previously logged this target, is next directly connected to and logins;Otherwise, need according to following
Realize reactivating for certification.
Nullify first and after logging in, restart iscsi services, and searched after the database for generating before this is deleted again
Target, and log in, process is as follows:
1) log off, i.e. iscsiadm-m node-T iqn.2011-09.com.example.ts1:disk1-p
192.168.0.83:3260–u;
2) delete and log in vestige, i.e. iscsiadm-m node-T iqn.2011-09.com.example.ts1:
disk1-p 192.168.0.83:3260-o delete;
3) data for logging in generation before this are deleted, i.e.,:
rm-rf/var/lib/iscsi/nodes/iqn.2011-09.com.example.tg1:disk1
rm-rf-rf/var/lib/iscsi/send_targets/192.168.0.83,3260
4) service of restarting, i.e. service iscsid restart
5) carry is logged in again, i.e.,:
iscsiadm-m discovery-t sendtargets-p 192.168.0.83;iscsiadm-m node-T
iqn.2011-09.com.example.ts1:disk1-p 192.168.0.83:3260–l。
