iSCSI服務器以及客戶端安裝配置

操作系統：CentOS 6.5 x86_64

軟件版本：scsi-target-utils-1.0.24

iscsi-initiator-utils-6.2.0.873

1.安裝iSCSI target

yum install scsi-target-utils -y

service tgtd start

chkconfig tgtd on

2.創建虛擬磁盤文件

dd if=/dev/zero of=/iscsi_data/ocr1.img bs=1M count=1024

dd if=/dev/zero of=/iscsi_data/ocr2.img bs=1M count=1024

dd if=/dev/zero of=/iscsi_data/ocr3.img bs=1M count=1024

dd if=/dev/zero of=/iscsi_data/data1.img bs=1M count=20480

dd if=/dev/zero of=/iscsi_data/fra1.img bs=1M count=10240

3.編輯配置文件

[root@target ~]# rpm -ql scsi-target-utils

/etc/rc.d/init.d/tgtd

/etc/sysconfig/tgtd

/etc/tgt/targets.conf

/usr/sbin/tgt-admin

/usr/sbin/tgt-setup-lun

/usr/sbin/tgtadm

/usr/sbin/tgtd

/usr/sbin/tgtimg

[root@target ~]# vi /etc/tgt/targets.conf

backing-store /iscsi_data/ocr1.img

backing-store /iscsi_data/ocr2.img

backing-store /iscsi_data/ocr3.img

backing-store /iscsi_data/data1.img

backing-store /iscsi_data/fra1.img

</target>

4.重新啓動tgtd服務

[root@target ~]# service tgtd restart

停止 SCSI target daemon： [確定]

正在啓動 SCSI target daemon： [確定]

[root@target ~]# tgtadm --mode target --op show

5.在Windows客戶端發現服務器

登錄到target，可以看到磁盤

6.Linux客戶端操作

安裝iscsi initiator

[root@rac1 ~]# yum install -y iscsi-initiator-utils

配置客戶端的initiatorname

[root@rac1 ~]# vi /etc/iscsi/initiatorname.iscsi

設置開機啓動

[root@rac1 ~]# chkconfig iscsid on

發現target服務器

[root@rac1 ~]# iscsiadm -m discovery -t sendtargets -p 192.168.253.200:3260

192.168.253.200:3260,1 iqn.2016-04.target:vdisk

接入iscsi target

[root@rac1 ~]# iscsiadm -m node -T iqn.2016-04.target:vdisk -l

Logging in to [iface: default, target: iqn.2016-04.target:vdisk, portal: 192.168.253.200,3260] (multiple)

查看磁盤正常

[root@rac1 ~]# fdisk -l

Disk /dev/sdi: 21.5 GB, 21474836480 bytes

64 heads, 32 sectors/track, 20480 cylinders

Units = cylinders of 2048 * 512 = 1048576 bytes
