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 ~]# 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.serviceCreated 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 3260tcp 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)
