ifconfig...没有看到eth0.。然后重启网卡又报下面错误。
故障现象:
service network restart
Shutting down loopback insterface: [ OK ]
Bringing up loopback insterface: [ OK ]
Bringing up interface eth0: Device eth0 does not seem to be present,delaying initialization. [FAILED]
CentOS Linux解决Device eth0 does not seem to be present
解决办法:
首先,打开/etc/udev/rules.d/70-persistent-net.rules内容如下面例子所示:
# vi /etc/udev/rules.d/70-persistent-net.rules
# This file was automatically generated by the /lib/udev/write_net_rules
# program, run by the persistent-net-generator.rules rules file.
#
# You can modify it, as long as you keep each rule on a single
# line, and change only the value of the NAME= key.
# PCI device 0x1022:0x2000 (pcnet32)
SUBSYSTEM=="net", ACTION=="add", DRIVERS=="?*", ATTR{address}=="00:0c:29:8f:89:9
7", ATTR{type}=="1", KERNEL=="eth*", NAME="eth0"
# PCI device 0x1022:0x2000 (pcnet32)
SUBSYSTEM=="net", ACTION=="add", DRIVERS=="?*", ATTR{address}=="00:0c:29:50:bd:1
7", ATTR{type}=="1", KERNEL=="eth*", NAME="eth1"
记录下,eth1网卡的mac地址00:0c:29:50:bd:17
接下来,打开/etc/sysconfig/network-scripts/ifcfg-eth0
# vi /etc/sysconfig/network-scripts/ifcfg-eth0
将 DEVICE="eth0" 改成 DEVICE="eth1" ,
将 HWADDR="00:0c:29:8f:89:97" 改成上面的mac地址 HWADDR="00:0c:29:50:bd:17"
最后,重启网络
# service network restart
或者
# /etc/init.d/network restart
正常了

-----------hostname-----------------
#机器名字命名规则
hd-"安装的服务名称"
1、配置主机文件
#1.1修改hostname
vi /etc/sysconfig/network
#修改
HOTSNAME=hd-'IP地址'.'机器名字'
hostname hd-'IP地址'.'机器名字'
#-----------------解决发现换ip和hostname也启动不起来--------------------
#1.2配置agent
vi /etc/cloudera-scm-agent/config.ini
server_host=172.30.1.101
rm -f /var/lib/cloudera-scm-agent/uuid
2、修改hosts
登录到172.30.1.manager 修改hosts
vi /etc/hosts
#添加一行 ip 新机器的hostname 机器名称
172.30.1.xx hd-'IP地址'.'机器名字' '机器名字'
开始scp
scp /etc/hosts root@每台机器:/etc/
3、检查网络
在新机器上
ping hd-cdhmg
在101
ping '机器名字'
