iscsi 配置 实现存储扩展

yum install scsi-target-utils -y

dd if=/dev/zero of=iscsi.img bs=1G count=2

chcon -R -t tgtd_var_lib_t /iscsi.img

vi /etc/tgt/targets.conf

backing-store /iscsi.img
initiator-address 192.168.1.0/24
write-cache off

 

systemctl restart tgtd.service
 lsof -i:3260
 tgt-admin --show

测试在windows上添加一个磁盘

实现linux的iscsi客户端   并实现chap加密

server端

vi /etc/tgt/targets.conf

backing-store /iscsi.img
initiator-address 192.168.1.0/24
incominguser han han
write-cache off

 

systemctl restart tgtd.service

 

tgt-admin --show

 

 

客户端

yum install iscsi-initiator-utils -y

vi /etc/iscsi/initiatorname.iscsi

InitiatorName=iqn.2017-02.com.han:hanlei

 

vi /etc/iscsi/iscsid.conf

node.session.auth.authmethod = CHAP
node.session.auth.username = han
node.session.auth.password = han
node.session.timeo.replacement_timeout = 20

 

iscsiadm -m discovery -t sendtargets -p 192.168.1.142

iscsiadm -m node -T iqn.2017-02.com.junxi:iscsi -l

lsblk

iscsiadm -m node -T iqn.2017-02.com.junxi:iscsi -u  #卸载
