服务端：
首先拿出一块分区/dev/sda5
# yum search target
# yum install scsi-target-utils.x86_64 -y //服务端的包
# vim /etc/tgt/targets.conf //编辑服务端的配置
<target redhat:1> //共享出这块分区的名字为redhat:1
backing-store /dev/sda5
</target>
/etc/init.d/tgtd restart //重启服务
客户端的安装：
# yum search iscsi 查找到iscsi软件包并安装
[root@redhat conf.d]# iscsiadm -m discovery -t st -p 192.168.3.60 //首先发现服务端的这块分区
Starting iscsid: [ OK ]
192.168.3.60:3260,1 redhat:1
[root@redhat conf.d]#
[root@redhat conf.d]# iscsiadm -m node -T redhat:1 -p 192.168.3.60 -l //使用进入这块分区
