## Centos7上target实验 ##

*  实验解释：在Linux存储侧上添加两块磁盘分别为1G、2G分别将磁盘分给windows主机、Linux主机。并且主机能够使用
 *  实验材料及配置IP  
    Centos7存储侧IP：197.168.197.200  
    Centos7主机侧IP：197.168.197.201  
    window servier 2012 IP:192.168.197.202  
    以下在放火墙、SELinux关闭的条件下进行

#### 一、Centos7储存侧操作 ####

##### 1.添加磁盘发现磁盘 #####

[root@localhost ~]#  fdisk  - l

##### 2.检查是否存在targetcli包(存在跳到第4步) #####

[root@localhost ~]#  rpm -qa | grep  targetcli

![在这里插入图片描述][56d3a64d45bd41f79c5ef42d80ddfe0f.png]

##### 3.安装targetcli #####

[root@localhost ~]#  yum install -y targetcli

![在这里插入图片描述][watermark_type_d3F5LXplbmhlaQ_shadow_50_text_Q1NETiBA6I-c6bif5Lit55qE5ouW5ouJ5py6_size_17_color_FFFFFF_t_70_g_se_x_16]

##### 4.进入target交互 #####

[root@localhost ~]#  targetcli

![在这里插入图片描述][b947555b4d2d44a483af3323a954f1fc.png]

##### 5.创建一个块存储 #####

Windows: /backstores/block create dev=/dev/sd\* name=自取

.>cd /backstores/block
    /backstores/block>  create dev=/dev/sdb name=win_storage

![在这里插入图片描述][641d07d4ff884131a4a360b88812c3c3.png]  
Linux: /backstores/block create dev=/dev/sd\* name=自取

/backstores/block>  create dev=/dev/sdc name=linux_storage

![在这里插入图片描述][149bc1c08d4f49b0ba4d0f7649b272d9.png]

##### 6.配置ISCSITarget命名 #####

iqn格式举例： Iqn.2021-12.example.com:west  
Windows: /iscsi create iqn.\*  
Linux: /iscsi create iqn.\*(同上)

/backstores/block> cd /iscsi 
    /iscsi> create iqn.2021-11.com.linux:2021
    /iscsi> create iqn.2021-11.com.win:2021

##### 7.创建ACL允许ISCSI客户机连接 #####

Windows: /iscsi/iqn.(上面创建的windows的iqn)/tpg1/acls create iqn.(此iqn为主机iqn，需前往主机侧查看）  
Win主机查看：  
![在这里插入图片描述][watermark_type_d3F5LXplbmhlaQ_shadow_50_text_Q1NETiBA6I-c6bif5Lit55qE5ouW5ouJ5py6_size_11_color_FFFFFF_t_70_g_se_x_16]

Linux: /iscsi/iqn.(上面创建的linux的iqn)/tpg1/acls create iqn.(主机侧查看)  
linux主机查看：

[root@localhost ~]#   cat /etc/iscsi/initiatorname.iscsi

![在这里插入图片描述][3a914903d86948509aa188647f4d87d8.png]

/iscsi> iqn.2021-11.com.win:2021/tpg1/acls create iqn.2021-11.com.windows:win-2021
    /iscsi> iqn.2021-11.com.linux:2021/tpg1/acls create iqn.1994-05.com.redhat:d9e525c60c5

![在这里插入图片描述][70bfeb40f1674725aa20b068e95dbd38.png]

##### 8.创建lun（target块设备的逻辑单元） #####

Win: /iscsi/iqn.(上面创建的windows的iqn)/tpg1/luns create /backstores/block/上面自取的块存储名字  
Linux: /iscsi/iqn.(上面创建的linux的iqn)/tpg1/luns create /backstores/block/上面自取的块存储名字

/iscsi> iqn.2021-11.com.linux:2021/tpg1/luns create /backstores/block/linux_storage 
    /iscsi> iqn.2021-11.com.win:2021/tpg1/luns create /backstores/block/win_storage

![在这里插入图片描述][5a297381a4bd4660a5df1ce5d7511bf8.png]

##### 9.创建ip与端口 #####

/>/iscsi/iqn.2021-11.com.linux:2021/tpg1/portals create192.168.13.30  
或  
/>cd /iscsi/iqn.2021-11.com.linux:2021/tpg1/portals  
/>create 192.168.197.200:3260  
注：192.18.13.30为服务器IP；不指定端口默认为3260

##### 10.配置完成后查看配置信息，并退出。 #####

#### linux主机侧 ####

rpm -qa | grep initiator-utils(已安装，下一步；未安装，安装)

[root@localhost ~]#  rpm -qa | grep  iscsi

![在这里插入图片描述][b229dfcde7064fb8836d9bf9513694bb.png]

发现目标并登录

[root@localhost ~]#  iscsiadm  –m  discovery  –t  st  –p 存储侧ip
    [root@localhost ~]#  iscsiadm  -m  node  - l

发现磁盘

[root@localhost ~]# fdisk  - l

![在这里插入图片描述][d304ea1304fe4d808d7ec36e201a86a9.png]  
创建挂载点并挂载

[root@localhost ~]# mkdir  /mnt/*(自取)
    [root@localhost ~]# mount  /dev/sd*(上面查看到的磁盘)  /mnt/(见上一行)
