1.安装服务
[root@server ~]# yum -y install targetd targetcli #安装服务
2.启动服务
[root@localhost qtx]# systemctl start target [root@localhost qtx]# systemctl enable target [root@localhost qtx]# systemctl status target
3.设置防火墙
[root@localhost qtx]# firewall-cmd --add-port=3260/tcp --permanent success [root@localhost qtx]# firewall-cmd --reload success [root@localhost qtx]# firewall-cmd --list-ports 3260/tcp
一、客户端
1.指定磁盘
[root@localhost qtx]# targetcli targetcli shell version 2.1.53 Copyright 2011-2013 by Datera, Inc and others. For help on commands, type 'help'. /> /backstores/block create fwq0.disk1 /dev/sdb Created block storage object fwq0.disk1 using /dev/sdb. /> exit Global pref auto_save_on_exit=true Configuration saved to /etc/target/saveconfig.json
2.创建iqn名字和iscsi对象
[root@localhost qtx]# targetcli targetcli shell version 2.1.53 Copyright 2011-2013 by Datera, Inc and others. For help on commands, type 'help'. /> /iscsi create iqn.2022-04.com.qtx:sdb1 Created target iqn.2022-04.com.qtx:sdb1. Created TPG 1. Global pref auto_add_default_portal=true Created default portal listening on all IPs (0.0.0.0), port 3260. /> exit Global pref auto_save_on_exit=true Last 10 configs saved in /etc/target/backup/. Configuration saved to /etc/target/saveconfig.json
3.设置iscsi对象和客户端ip
[root@localhost qtx]# targetcli targetcli shell version 2.1.53 Copyright 2011-2013 by Datera, Inc and others. For help on commands, type 'help'. /> /iscsi/iqn.2022-04.com.qtx:sdb1/tpg1/acls create iqn.2022-04.com.qtx:user1 Created Node ACL for iqn.2022-04.com.qtx:user1 /> exit Global pref auto_save_on_exit=true Last 10 configs saved in /etc/target/backup/. Configuration saved to /etc/target/saveconfig.json
4.创建lun 绑定块
[root@localhost qtx]# targetcli targetcli shell version 2.1.53 Copyright 2011-2013 by Datera, Inc and others. For help on commands, type 'help'. /> /iscsi/iqn.2022-04.com.qtx:sdb1/tpg1/luns create
二、客户端
1.安装工具
[root@localhost qtx]# yum -y install targetd targetcli
2.initiator命名
[root@client ~]# vim /etc/iscsi/initiatorname.iscsi InitiatorName=iqn.2022-04.com.qts:sdb1
3.启动服务
[root@localhost qtx]# systemctl start iscsi [root@localhost qtx]# systemctl enable iscsi [root@localhost qtx]# systemctl status iscsi
4.发现存储
[root@localhost qtx]# iscsiadm -m discovery -t st -p 192.168.190.129 192.168.190.129:3260,1 iqn.2022-04.com.qtx:sdb1
5.登陆存储 连接
[root@localhost qtx]# iscsiadm -m discovery -t st -p 192.168.190.129 -l
6.验证
[root@localhost qtx]# lsscsi
