首先在服务端设置
[root@localhost ~]# yum -y install targetd targetcli 下载targetd targetcli 这两个软件 [root@localhost ~]# systemctl start targt [root@localhost ~]# systemctl enable target Created symlink from /etc/systemd/system/multi-user.target.wants/target.service to /usr/lib/systemd/system/target.service. [root@localhost ~]# firewall-cmd --add-port=3260/tcp --permanent 设置防火墙3260端口 [root@localhost ~]# firewall-cmd --reload 重启防火墙 （一般我喜欢关闭防火墙） [root@localhost ~]# firewall-cmd --list-ports 查看端口可不可用 端口号是绿色是可用的 使用targetcli 命令 [root@localhost ~]# targetcli Warning: Could not load preferences file /root/.targetcli/prefs.bin. targetcli shell version 2.1.fb46 Copyright 2011-2013 by Datera, Inc and others. For help on commands, type 'help'. 你要发布的磁盘 /> /backstores/block create yousa /dev/sdb Created block storage object yousa using /dev/sdb. 创建iqn名字 创建iscsi /> /iscsi create iqn.2020-05.com.bdqn:disk1 Created target iqn.2020-05.com.bdqn:disk1.

绑定lun块 /> /iscsi/iqn.2020-05.com.bdqn:disk1/tpg1/luns create /backstores/block/yousa Created LUN 0. Created LUN 0->0 mapping in node ACL iqn.2020-05.com.bdqn:client1
客户端
[root@localhost ~]# yum -y install iscsi-initiator-utils 安装工具
[root@localhost ~]# vim /etc/iscsi/initiatorname.iscsi InitiatorName=iqn.2020-05.com.bdqn:client1 给initiator命名
[root@localhost ~]# systemctl start iscsi 启动服务
[root@localhost ~]# systemctl enable iscsi 重启服务
[root@localhost ~]# systemctl status iscsi

发现硬盘
[root@localhost ~]# iscsiadm -m discovery -t st -p 192.168.1.60

登陆存储
[root@localhost ~]# iscsiadm -m discovery -t st -p 192.168.1.60 -l
