一.在linux下安装启动iscsi target
1.安装启动iscsi服务
[root@wjb10000 ~]# yum -y install targetcli.noarch
2.建立一个目录设置为iscsi设备
[root@wjb10000 ~]# mkdir /iscsi_disks
3.设置target
[root@wjb10000 ~]# targetcli Warning: Could not load preferences file /root/.targetcli/prefs.bin. targetcli shell version 2.1.fb41 Copyright 2011-2013 by Datera, Inc and others. For help on commands, type 'help'. /> cd backstores/fileio /backstores/fileio> create disk01 /iscsi_disks/disk01.img 20G Created fileio disk01 with size 21474836480 /backstores/fileio> cd /iscsi /iscsi> create iqn.2016-06.wjb.com:storage.target0 Created target iqn.2016-06.wjb.com:storage.target0.

Configuration saved to /etc/target/saveconfig.json
4.设置防火墙
[root@wjb10000 ~]# vim /etc/firewalld/services/iscsi.xml <?xml version="1.0" encoding="utf-8"?> <service> <short>ISCSI</short> <description>ISCSI protocal</description> <port protocal="tcp" port="3260"> </service> [root@wjb10000 ~]# firewall-cmd --permanent --add-service=iscsi [root@wjb10000 ~]# firewall-cmd --reload
5.启动服务
[root@wjb10000 ~]# systemctl enable target.service Created symlink from /etc/systemd/system/multi-user.target.wants/target.service to /usr/lib/systemd/system/target.service. [root@wjb10000 ~]# systemctl start target.service
6.查看端口
[root@wjb10000 ~]# netstat -lnp | grep 3260 tcp 0 0 192.168.1.50:3260 0.0.0.0:* LISTEN -
二.在linux下安装启动iscsi initiator
1.安装 iscsi-initiator-utils服务
[root@wjb10000 ~]# yum install iscsi-initiator-utils
