RHEL7部署ISCSI TARGET服務器
一、配置yum源
[[email protected] yum.repos.d]# vi /etc/yum.repos.d/local.repo
[local]
name=local
baseurl=file:///mnt/media/
enable=1
gpgcheck=0
二、掛載光盤
[[email protected] yum.repos.d]# mkdir /mnt/media/
[[email protected] yum.repos.d]# mount /dev/cdrom /mnt/media/
mount: /dev/sr0 is write-protected, mounting read-only
[[email protected] yum.repos.d]#
三、通過yum安裝targetcli
[[email protected] yum.repos.d]# yum install targetcli
Loaded plugins: langpacks, product-id, search-disabled-repos, subscription-manager

四、使用fdisk -l查看一下需要分享的磁盤是否正常
[[email protected] ~]# fdisk -l

[[email protected] ~]#
五、使用targetcli配置服務器
5、1先help一下，查看一下支持的命令有哪些
[[email protected] ~]# 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‘.
/> help
GENERALITIES
============
This is a shell in which you can create, delete and configure
configuration objects.
The available commands depend on the current path or target
path you want to run a command in: different path have
different sets of available commands, i.e. a path pointing at
an iscsi target will not have the same availaible commands as,
say, a path pointing at a storage object.
The prompt that starts each command line indicates your
current path. Alternatively (useful if the prompt displays
an abbreviated path to save space), you can run the
pwd command to display the complete current path.
Navigating the tree is done using the cd command. Without
any argument, cd will present you wil the full objects
tree. Just use arrows to select the destination path, and
enter will get you there. Please try help cd for navigation
tips.
COMMAND SYNTAX
==============
Commands are built using the following syntax:
[TARGET_PATH] COMMAND_NAME [OPTIONS]
The TARGET_PATH indicates the path to run the command from.
If ommited, the command will be run from your current path.
The OPTIONS depend on the command. Please use help
COMMAND to get more information.
AVAILABLE COMMANDS
==================
The following commands are available in the
current path:
- bookmarks action [bookmark]
- cd [path]
- clearconfig [confirm]
- exit
- get [group] [parameter...]
- help [topic]
- ls [path] [depth]
- pwd
- refresh
- restoreconfig [savefile] [clear_existing]
- saveconfig [savefile]
- sessions [action] [sid]
- set [group] [parameter=value...]
- status
- version

六、查看targetcli的狀態及端口號是否正常
[[email protected] ~]# systemctl is-active target.service
active
[[email protected] ~]# netstat -tunlp|grep 3260
tcp 0 0 0.0.0.0:3260 0.0.0.0:* LISTEN -
七、防火墻放行並設置開機啟動
[[email protected] ~]# firewall-cmd --add-service=iscsi-target --permanent
success
[[email protected] ~]# systemctl enable target
八、可以使用windows或linux掛載並使用了
