安装服务

服务端：yum install targetcli -y            #安装共享磁盘服务systemctl start target              #启动服务targetcli                           #打开设置客户端:yum install iscsi-initiator-utils.64_86 -y          #安装systemctl start iscsi                               #启动

===================================================================
服务端配置（首先要先建立一个磁盘分区大小随意）：

/backstores/block create westos:storage1 /dev/vda1/iscsi/ create iqn.2017-12.com.example:storage1/iscsi/iqn.2017-12.com.example:storage1/tpg1/acls create iqn.2017-12.com.example:westoskeyiscsi/iqn.2017-12.com.example:storage1/tpg1/portals create 172.25.254.201/iscsi/iqn.2017-12.com.example:storage1/tpg1/luns create /backstores/block/westos:storage1firewall-cmd --permanent --add-port=3260/tcpfirewall-cmd --rel
