设置 Linux 主机的认证

您可以为 Linux 主机设置单向 CHAP 认证。

要设置 Linux 主机的认证，请执行以下步骤：

1. 使用适当的编辑器打开 /etc/iscsi/iscsid.conf 或 /etc/iscsid.conf。
2. 转至 CHAP 设置段。

   以下示例显示了输出：

   Figure 1. Linux 主机的 CHAP 设置

   #*************
   #CHAP Settings

   #To enable CHAP authentication set node.session.auth.authmethod
   #to CHAP. The default is None.
   #node.session.auth.authmethod = CHAP
   
   #To set a CHAP username and password for initiator
   #authentication by the target(s), uncomment the following lines:
   #node.session.auth.username = username
   #node.session.auth.password = password
   node.session.auth.username = rhel_username
   node.session.auth.password = xxxxxxxxxxxxx
   #To set a CHAP username and password for target(s)
   #authentication by the initiator, uncomment the following lines:
   #node.session.auth.username_in = username_in
   #node.session.auth.password_in = password_in
   node.session.auth.password_in = yyyyyyyyyyyyy
   #To enable CHAP authentication for a discovery session to the target
   #set discovery.sendtargets.auth.authmethod to CHAP. The default is None.
   #discovery.sendtargets.auth.authmethod = CHAP
   discovery.sendtargets.auth.authmethod = CHAP
   #To set a discovery session CHAP username and password for the initiator
   #authentication by the target(s), uncomment the following lines:
   #discovery.sendtargets.auth.username = username
   #discovery.sendtargets.auth.password = password
   
   #To set a discovery session CHAP username and password for target(s)
   #authentication by the initiator, uncomment the following lines:
   #discovery.sendtargets.auth.username_in = username_in
   #discovery.sendtargets.auth.password_in = password_in

3. 设置单向认证。
   1. 设置发起程序名称的 CHAP 用户名和密码。
      1. node.session.auth.authmethod = CHAP
      2. node.session.auth.username = <initiator's user name>
      3. node.session.auth.password = <CHAP secret for host>
   2. 设置发起程序名称的发现会话 CHAP 用户名和密码。
      1. discovery.sendtargets.auth.authmethod = CHAP
      2. discovery.sendtargets.auth.username = <initiator's user name>
      3. discovery.sendtargets.auth.password = <CHAP secret for host>
   3. 保存这些设置。 您必须注销任何当前会话并重新发现系统 iSER 目标以使 CHAP 密码生效。
