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

4.设置防火墙

[root@wjb10000 ~]# vim /etc/firewalld/services/iscsi.xml

ISCSI

ISCSI protocal

[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

2.修改配置文件

[root@wjb10000 ~]# vim /etc/iscsi/initiatorname.iscsi

InitiatorName=iqn.2016-06.wjb.com:www.server.com

[root@wjb10000 ~]# vim /etc/iscsi/iscsid.conf

#node.session.auth.authmethod = CHAP

#node.session.auth.username = username

#node.session.auth.password = password //去掉注释

3.启动服务

[root@wjb10000 ~]# systemctl start iscsid

[root@wjb10000 ~]# systemctl enable iscsid

4.发现target

[root@wjb10000 ~]# iscsiadm -m discovery -t sendtargets -p 192.168.1.50

5.查看状态

[root@wjb10000 ~]# iscsiadm -m node -o show

6.登录target建立连接

[root@wjb10000 ~]# iscsiadm -m node --login

Logging in to [iface: default, target: iqn.2016-06.wjb.com:storage.target0, portal: 192.168.1.50,3260] (multiple)

Login to [iface: default, target: iqn.2016-06.wjb.com:storage.target0, portal: 192.168.1.50,3260] successful.

7.查看连接情况

[root@wjb10000 ~]# iscsiadm -m session -o show

tcp: [1] 192.168.1.50:3260,1 iqn.2016-06.wjb.com:storage.target0 (non-flash)

8.磁盘操作

[root@wjb10000 ~]# fdisk -l
