yum install -y scsi-target-utils
查看配置文件
ls /etc/tgt/targets.conf
查看服务端启动命令路径
find / -name "*tgtd"
/etc/sysconfig/tgtd
/etc/selinux/targeted/active/modules/100/tgtd
/usr/sbin/tgtd

启动
/usr/sbin/tgtd start
netstat -antup | grep 3260
systemctl enable tgtd.service

fdisk /dev/sdb 创建/dev/sdb1 /dev/sdb2

重启

vim /etc/tgt/targets.conf

<target iqn.2024-04.host1:target_san1>
backing-store /dev/sdb1
initiator-address 192.168.40.131
initiator-address 192.168.40.130
vendor_id host1
product_id target1
</target>

<target iqn.2024-04.host1:target_san2>
backing-store /dev/sdb2
initiator-address 192.168.40.131
initiator-address 192.168.40.130
vendor_id host1
product_id target2
</target>

initiator-address 设置可以访问的客户端的ip地址
systemctl restart tgtd
systemctl status tgtd
