How Linux builds iSCSI shared storage

iSCSI Service-Side IP192.168.254.172

Client 1 192.168.254.46

Client 2 192.168.254.158

Service-side configuration

1, the service side installs the Scsi-target-utils

[Root@localhost ~]# Yum Install scsi-target-utils-y

2, if there is a separate partition, you can use a separate partition, if there is no suitable partition can be dd a large file as a shared disk

[Root@localhost/]# dd If=/dev/zero of=/disk1 bs=1m count=3000

3000+0 Records in

3000+0 Records out

3145728000 bytes (3.1 GB) copied, 11.618 seconds, 271 MB/s

3, modify the iSCSI main configuration file

[Root@localhost ~]# vi/etc/tgt/targets.conf

<target iqn.2013-12.com.make:ws.httpd>

Backing-store/disk1

</target>

4. Start TGTD Service

[Root@localhost ~]#/ETC/INIT.D/TGTD Restart

Stopping SCSI target daemon:stopping target Framework Daemon

[OK]

Starting SCSI target daemon:starting Target Framework Daemon

Second, the client configuration

1, install the client

[Root@zabbix-client1 ~]# Yum Install iscsi-initiator-utils-y

2, start the client

[Root@zabbix-client1 ~]# iscsiadm-m discovery-t sendtargets-p 192.168.254.172

Starting iscsid:[OK]

192.168.254.172:3260,1 iqn.2013-12.com.make:ws.httpd

192.168.254.172:3260,1 Iqn.2013-12.com.make:ws.mysqld

3. Use client to find Mount storage

[Root@zabbix-client1 ~]# iscsiadm-m node-t iqn.2013-12.com.make:ws.httpd-l

Logging in to [Iface:default, TARGET:IQN.2013-12.COM.MAKE:WS.HTTPD, portal:192.168.254.172,3260] (multiple)

Login to [Iface:default, TARGET:IQN.2013-12.COM.MAKE:WS.HTTPD, portal:192.168.254.172,3260] successful.

4. Partition the two disks mounted on the client and format them into EXT4 format file system
