服务器ipmi远程管理

DELL iDRAC (Integrated Dell™ Remote Access Controller )是 Dell PowerEdge 系列服务器上的远程管理方案， 11代 12代服务器已经集成此管理卡，用户无须购置其它任何设备即可实现服务器底层管理，如系统崩溃恢复，电源控制 ，BIOS 设置。如果再搭配其DRAC Enterprise 控制卡，可实现图形界面下登录到控制台。

特点：
1. 独立于操作系统和BIOS，服务器无须安装任何程序，只须作相应配置即可。
2. 主控端无须安装任何额外设备，使用 Telnet/SSH/浏览器方式即可控制 。
3. 可以实现对BIOS甚至操作系统的完全控制。

功能：
1. 在操作系统崩溃，死机或 BIOS自检出错情况下，远程重启/开机/关机。
2. 通过串口重定向，实现远程对服务器BIOS 启动过程的完全控制。
3. 远程实时查看Linux启动时控制台的输出。
4. 通过串口远程登录到Linux, 典型的应用场景：以单用户模式通过串口登录到Linux, 执行系统紧急救援  。
5.  远程通过PXE 自动给 服务器安装操作系统 (windows/Linux均可 ) 。

iDRAC6配置

1.登录iDRAC配置界面

服务器开机自检时, 出现以下画面时, 按Ctrl + E进入.



2.开启IPMI功能

iDRAC6 LAN切换至On, IPMI Over LAN切换至On



3.配置网络参数

选择LAN Parameters进入. NIC Selection 有几个参数可供选择. 我们一般选择Shared方式

'Dedicated'（专用）— 选择此选项可以使远程访问设备能够使用 iDRAC Enterprise 上的专用网络接口。此接口不与主机操作系统共享并会将管理通信路由到单独的物理网络，从而能够与应用程序通信分开。此选项只有在系统中装有 iDRAC6 Enterprise 时才可用。安装 iDRAC6 Enterprise 卡后，确保更改"NIC Selection"（NIC 选择）为"Dedicated"（专用）。这可以通过 iDRAC6 配置公用程序、iDRAC6 Web 界面或通过 RACADM 完成。

'Shared'（共享）— 选择此选项可以与主机操作系统共享网络接口。当主机操作系统针对 NIC 组配置后，远程访问设备网络接口将具有全部功能。远程访问设备通过 NIC 1 和 NIC 2 接收数据，但是只通过 NIC 1 发送数据。如果 NIC 1 出现故障，远程访问设备将不可访问。

'Shared with Failover LOM2'（与故障转移 LOM2 共享）— 选择此选项可以与主机操作系统共享网络接口。当主机操作系统针对 NIC 组配置后，远程访问设备网络接口将具有全部功能。远程访问设备通过 NIC 1 和 NIC 2 接收数据，但是只通过 NIC 1 发送数据。如果 NIC 1 出现故障，远程访问设备会故障转移到 NIC 2 进行所有数据发送。远程访问设备会继续使用 NIC 2 进行数据发送。如果 NIC 2 出现故障，远程访问设备会故障转移回 NIC 1 来进行所有数据发送，但前提是 NIC 1 中的故障已经得以纠正。

'Shared with Failover All LOMs'（与故障转移所有 LOM 共享）— 选择此选项可以与主机操作系统共享网络接口。当主机操作系统针对 NIC 组配置后，远程访问设备网络接口将具有全部功能。远程访问设备通过 NIC 1、NIC 2、NIC 3 和 NIC 4 接收数据，但是只通过 NIC 1 发送数据。如果 NIC 1 出现故障，远程访问设备会故障转移回 NIC 2 来进行所有数据发送。如果 NIC 2 出现故障，远程访问设备会故障转移回 NIC 3 来进行所有数据发送。如果 NIC 3 出现故障，远程访问设备会故障转移回 NIC 4 来进行所有数据发送。如果 NIC 4 出现故障，远程访问设备会故障转移回 NIC 1 来进行所有数据发送，但前提是原来的 NIC 1 故障已经得以纠正。此选项可能在 iDRAC6 Enterprise 上不可用。

光标向下移动, 可以配置IPV4地址



4.用户管理

移动光标到LAN User Configuration, 进入. 默认用户名root 密码calvin, 改成我们所需要的用户名及密码

加电自检过程中, 按F2进入系统设置
