iSCSI服务器以及客户端安装配置

操作系统:CentOS 6.5 x86_64

软件版本:scsi-target-utils-1.0.24

      iscsi-initiator-utils-6.2.0.873


1.安装iSCSI target

yum install scsi-target-utils -y

service tgtd start

chkconfig tgtd on


2.创建虚拟磁盘文件

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.编辑配置文件

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

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

/etc/sysconfig/tgtd

/etc/tgt/targets.conf

/usr/sbin/tgt-admin

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

<target iqn.2016-04.target:vdisk>

    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.重新启动tgtd服务

[root@target ~]# service tgtd restart

停止 SCSI target daemon:                                  [确定]

6.Linux客户端操作

安装iscsi initiator

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

配置客户端的initiatorname

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

设置开机启动

[root@rac1 ~]# chkconfig iscsid on

发现target服务器

[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)

Login to [iface: default, target: iqn.2016-04.target:vdisk, portal: 192.168.253.200,3260] successful.
