输入 targetcli
命令后会提示配置文件不存在,使用 exit
会自动生成配置文件:
1 2 3 4 5 6 7 8 9 [root@localhost ~]# targetcli Warning: Could not load preferences file /root/ .targetcli/prefs.bin. targetcli shell version 2.1 .53 Copyright 2011 -2013 by Datera, Inc and others. For help on commands, type 'help' . /> exit Global pref auto_save_on_exit=true Configuration saved to /etc/ target/saveconfig.json
服务启动 启动服务:
1 [root@localhost ~]# systemctl start target
设置开机启动:
1 2 [root@localhost ~]# systemctl enable target Created symlink /etc/ systemd/system/mu lti-user.target.wants/target.service → /u sr/lib/ systemd/system/ target.service.
创建存储 这里我们以/dusays/目录为例,使用命令 /backstores/fileio create dusays /dusays/dusays.img 1G
创建名为 dusays 的 1G 大小存储文件,创建后通过 ls
查看执行结果:
1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 [root@localhost ~]# mkdir /dusays [root@localhost ~]# targetcli targetcli shell version 2.1.53 Copyright 2011-2013 by Datera, Inc and others.

接下来我们创建名为 iqn.2021-01.com.dusays:www 的 iSCSI 文件,一般命名规则为 iqn.年份-月份.网址倒叙:存储文件名称,完整命令为 /iscsi create iqn.2021-01.com.dusays:www
,创建后通过 ls
查看执行结果:

创建 LUN 号 从先前创建的 www 存储中创建 LUN 号,命令为 iscsi/iqn.2021-01.com.dusays:www/tpg1/luns/ create /dusays/www.img
,创建后通过 ls
查看执行结果:
1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 21 22 23 24 25 /> iscsi/iqn.2021-01.com.dusays:www/tpg1/luns/ create /dusays/www.img Created storage object dusays-www.img.

为启动器 iqn.2021-01.com.dusays:www 创建 ACL,以便 iSCSI 客户端可以访问此目标中的 LUN,命令为 iscsi/iqn.2021-01.com.dusays:www/tpg1/acls create iqn.2021-01.com.dusays:init
通过 ls
查看执行结果,通过 saveconfig
保存所有的配置,并使用 exit
退出:
