首先是安装，在配置好yum源的情况下直接安装scsi-target-utils即可yum -y install scsi-target-utils
然后查看下scsi-target-utils的信息
[root@monitor ~]# yum info scsi-target-utils
Loaded plugins: fastestmirror, refresh-packagekit, security
Loading mirror speeds from cached hostfile

[root@monitor ~]#
启动iscsi服务
[root@monitor ~]# service tgtd start
tgtadm --lld <driver> --op new --mode target --tid <id> --targetname <name>
<driver> 表示要加载的驱动类型（一般为iscsi）
<id> 指定target的id号
<name> 指定iqn名称一般是iqn.日期.翻转域名.磁盘名称
创建一个target
[root@monitor ~]# tgtadm --lld iscsi --op new --mode target --tid=1 --targetname iqn.20150808.com.52itw:disk1
[root@monitor ~]#
查看当前建好的target
[root@monitor ~]# tgtadm --lld iscsi --op show --mode target
Target 1: iqn.20150808.com.52itw:disk1

给target创建lun并且添加硬盘（可以多次执行添加多块，不过注意lun不可以重复出现）
[root@monitor ~]# tgtadm --lld iscsi --op new --mode logicalunit --tid 1 --lun 1 --backing-store /dev/sdb
[root@monitor ~]# tgtadm --lld iscsi --op new --mode logicalunit --tid 1 --lun 2 --backing-store /dev/sdc
创建ACL访问控制
[root@monitor ~]# tgtadm --lld iscsi --op bind --mode target --tid 1 --initiator-address ALL
将tid绑定到特定的客户端IP，仅绑定的主机可以访问本iscsi，这里我们使用的all表示所有主机均可以访问
查看当target信息

客户端挂载
安装iscsi客户端程序yum -y install iscsi-initiator-utils
[root@monitor ~]# iscsiadm --mode discoverydb --type sendtargets --portal 172.30.1.14 --discover
