注意：MAC地址與網絡卡名稱一定要對應上，可以通過

重啟裝置
reboot # 重啟後 ip a <<"COMMENT" 1: lo: <LOOPBACK,UP,LOWER_UP> mtu 65536 qdisc noqueue state UNKNOWN group default qlen 1000 link/loopback 00:00:00:00:00:00 brd 00:00:00:00:00:00 inet 127.0.0.1/8 scope host lo valid_lft forever preferred_lft forever inet6 ::1/128 scope host valid_lft forever preferred_lft forever 2: eth0: <BROADCAST,MULTICAST,UP,LOWER_UP> mtu 1500 qdisc mq state UP group default qlen 1000 link/ether 0c:c4:7c:7g:af:50 brd ff:ff:ff:ff:ff:ff inet 10.13.14.202/24 brd 10.13.14.255 scope global noprefixroute eth0 valid_lft forever preferred_lft forever inet6 fe80::ec4:7aff:fe7e:ef20/64 scope link noprefixroute valid_lft forever preferred_lft forever 3: eth1: <NO-CARRIER,BROADCAST,MULTICAST,UP> mtu 1500 qdisc mq state DOWN group default qlen 1000 link/ether 0c:c4:7c:7g:af:51 brd ff:ff:ff:ff:ff:ff COMMENT

- 很多人喜歡執行重啟network服務，來設定IP。但不建議這樣，因為該命令是對所有網絡卡操作。建議使用”ifup”與”ifdown”命令操作單獨的網絡卡；
BMC的常用命令
# 安裝ipmitool工具 yum install -y ipmitool # 檢視BMC的IP型別與IP值 ipmitool lan print 1|grep "IP Address" <<'COMMENT' IP Address Source: Static Address IP Address: 10.13.14.20 COMMENT # 設定ipsrc的型別(dhcp/static)，set 1表示網路連線的型別，為channel1 ipmitool lan set 1 ipsrc static # 設定靜態IP ipmitool lan set 1 ipaddr 172.20.1.1 # 檢視楓樹轉速 ipmitool sdr list | grep -i '^FAN' <<'COMMENT' FAN1_Speed| 2000 RPM| ok FAN2_Speed| 2000 RPM| ok FAN3_Speed| 2000 RPM| ok FAN1_Present| 0x00| ok FAN2_Present| 0x00| ok FAN3_Present| 0x00| ok COMMENT
