Linux_iscsi配置完全步骤
1、安装iscsi‐initator‐utils包确定RedHat6.2上安装了iscsi‐initator‐utils使用以下命令查看是否安装：如下图所示，此服务器没有安装[root@Server3~]#rpm-qa|grepiscsi
2、注意要对应操作系统是32位还是64位，确认方法如下X86_64表示64位，其余均是32位[root@Server3~]#uname-m
3、挂载RedHat6.2安装光盘，插入操作系统安装盘，[root@Server3~]#mount/dev/cdrom/mnt
4、安装iscsi‐in坡纠课柩itator‐utils包[root@Server3~]#cd/mnt/Packages/[root@Server3Packages]#rpm-vihiscsi-initiator-utils-6.2.0.872-34.el6.x86_64.rpmwarning:iscsi-initiator-utils-6.2.0.872-34.el6.x86_64.rpm:HeaderV3RSA/SHA256Signature,keyIDfd431d51:NOKEYPreparing...###########################################[100%]1:iscsi-initiator-utils###########################################[100%][root@Server3Packages]#
5、查看Init坡纠课柩iatorname，查看文件/etc/iscsi/initiatorname.iscsi[root@Server3Packages]#cat/etc/iscsi/initiatorname.iscsiInitiatorName=iqn.1994-05.com.redhat:5674d1912c88--------------------------------------------------------------------------------注意：iqn.1994‐05.com.redhat:5674d1912c88即为HostID（WWWN/IQN）然后在存储端就能发现服务器的HostID号
6、启动iscsi服务[root@Server3Packages]#serviceiscsistart
7、使用chkconfig--listiscsi命令查看iscsi服务是否开机自启动如果2,3,4,5级别没有开启，使用chkconfigiscsion命令使iscsi服务开机自启动[root@Server3Packages]#chkconfig--listiscsiiscsi 0:off 1:off 2:off 3:on 4:on 5:on 6:off[root@Server3Packages]#chkconfigiscsion[root@Server3Packages]#chkconfig--listiscsiiscsi 0:off 1:off 2:on 3:on 4:on 5:on 6:off
8、发现Target：[root@Server3~]#iscsiadm-mdiscovery-tst-p192.168.10.100:3260192.168.10.100:3260,1iqn.1991-05.com.microsoft:iscsi-multipath-target192.168.20.100:3260,1iqn.1991-05.com.microsoft:iscsi-multipath-target
9、发现佯镧诱嚣只发现一次，连接通常有几条路径需要连接几次，看下图所示，此实验有两条路径[root@Server3~]#iscsiadm-mnode-p192.1鲂番黟谊68.10.100:3260-lLogginginto[iface:default,target:iqn.1991-05.com.microsoft:iscsi-multipath-target,portal:192.168.10.100,3260](multiple)Loginto[iface:default,target:iqn.1991-05.com.microsoft:iscsi-multipath-target,portal:192.168.10.100,3260]successful.[root@Server3~]#iscsiadm-mnode-p192.168.20.100:3260-lLogginginto[iface:default,target:iqn.1991-05.com.microsoft:iscsi-multipath-target,portal:192.168.20.100,3260](multiple)Loginto[iface:default,target:iqn.1991-05.com.microsoft:iscsi-multipath-target,portal:192.168.20.100,3260]successful.--------------------------------------------------------------------------------还有一种方法可以一次性全部连接，本人不推荐此方法[root@Server3~]#iscsiadm-mnode-l
10、查看磁盘已经映射成功，成功将存储设备挂着到Linux服务器上，大功告成
