先改改主机名：
[root@localhost ~]# echo "hostname cenots7.localdomain" >>/etc/sysconfig/network
[root@localhost ~]# rebootConnection to 192.168.150.180 closed by remote host.
Connection to 192.168.150.180 closed.xw@Opt9010:~$ ssh root@192.168.150.180
root@192.168.150.180's password:Last login: Thu Jul 10 10:01:09 2014
[root@cenots7 ~]#
看看网卡设置设置设备摆设摆设文件：
[root@cenots7 ~]# cd /etc/sysconfig/network-scripts/
[root@cenots7 network-scripts]# cat ifcfg-Auto_Ethernet
HWADDR=08:00:27:9A:A6:88TYPE=Ethernet
BOOTPROTO=dhcp DEFROUTE=yes
PEERDNS=yes PEERROUTES=yes
IPV4_FAILURE_FATAL=no IPV6INIT=yes
IPV6_AUTOCONF=yes IPV6_DEFROUTE=yes
IPV6_PEERDNS=yes IPV6_PEERROUTES=yes
IPV6_FAILURE_FATAL=no NAME="Auto Ethernet"
UUID=76304098-8f46-4185-8337-bb7f0d90423eONBOOT=yes
[root@cenots7 network-scripts]# cat ifcfg-enp0s3
HWADDR=08:00:27:9A:A6:88TYPE=Ethernet
BOOTPROTO=dhcp DEFROUTE=yes
PEERDNS=yes PEERROUTES=yes
IPV4_FAILURE_FATAL=no IPV6INIT=yes
IPV6_AUTOCONF=yes IPV6_DEFROUTE=yes
IPV6_PEERDNS=yes IPV6_PEERROUTES=yes
IPV6_FAILURE_FATAL=no NAME=enp0s3
UUID=66a635c2-9600-437b-8cfb-57e9569f68daONBOOT=no
看看两个文件有啥不合：
[root@cenots7 network-scripts]# diff ifcfg-Auto_Ethernet ifcfg-enp0s3
14,16c14,16NAMENAME="Auto Ethernet"
UUIDUUID=76304098-8f46-4185-8337-bb7f0d90423eONBOOTONBOOT=yes
---> NAME=enp0s3
> UUID=66a635c2-9600-437b-8cfb-57e9569f68da> ONBOOT=no
两个文件MAC地址一样，ifcfg-Auto_Ethernet ONBOOT=yes，然则ifconfig结果显示的是enp0s3，有点儿费解了。
再看看我复制KVM虚拟机时常常要改的网卡MAC地址：
root@cenots7 network-scripts]# ll /etc/udev/rules.d/
total 8-rw-r--r--. 1 root root 134 Jul9 00:47 60-vboxadd.rules
-rw-r--r--. 1 root root 352 Jul4 00:38 98-kexec.rules
[root@cenots7 network-scripts]# cat /etc/udev/rules.d/98-kexec.rulesSUBSYSTEM=="cpu", ACTION=="online", PROGRAM="/bin/systemctl try-restart kdump.service"
SUBSYSTEM=="cpu", ACTION=澳门新葡亰集团平台网址大全="offline", PROGRAM="/bin/systemctl try-restart kdump.service" SUBSYSTEM=="memory", ACTION=="add", PROGRAM="/bin/systemctl try-restart kdump.service"
SUBSYSTEM=="memory", ACTION=="remove", PROGRAM="/bin/systemctl try-restart kdump.service"
[root@cenots7 network-scripts]# cat /etc/udev/rules.d/60-vboxadd.rulesKERNEL=="vboxguest", NAME="vboxguest", OWNER="vboxadd", MODE="0660"
KERNEL=="vboxuser", NAME="vboxuser", OWNER="vboxadd", MODE="0666"
三、收集
setup对象照样保留了，但有差别，没有了收集设置设置设备摆设摆设，多了RHN（Centos到底是跟RedHat一家子了）
[root@localhost ~]# setup
好吧，我们看看收集设置设置设备摆设摆设。
[root@localhost ~]# cat /etc/resolv.conf
# Generated by NetworkManagernameserver 192.168.150.254

二、Services
[root@localhost ~]# chkconfig
Note: This output shows SysV services only and does not include native
sys澳门新葡亰集团平台网址大全temd services. SysV configuration data might be overridden by nativesystemd configuration.
If you want to list systemd services use 'systemctl list-unit-files'.
To see services enabled on particular target use'systemctl list-dependencies [target]'.

SysV已经快退居二线了，想设置设置设备摆设摆设办事得用systemctl，先看看默认启动的办事吧。（假如不用grep过滤一下，输出结果澳门新葡亰集团平台网址大全有260多行）
[root@localhost ~]# systemctl list-unit-files|grep enabled

默认居然没有启动sshd，晕！看看监听端口：
[root@localhost ~]# netstat -lntp
Active Internet connections (only servers)
Proto Recv-Q Send-Q Local AddressForeign AddressStatePID/Program name
tcp00 127.0.0.1:250.0.0.0:*LISTEN2090/master
70-persistent-net.rules呢？
网卡MAC只在网卡设置设置设备摆设摆设文件里有，一旦变了我只必要改网卡设置设置设备摆设摆设文件？
[root@cenots7 network-scripts]# grep -r "08:00:27:9A:A6:88" /etc/
/etc/sysconfig/network-scripts/ifcfg-enp0s3:HWADDR=08:00:27:9A:A6:88
