[3] CentOS基本设置

 

一、配置网卡

如果虚拟机复制后，选择“I copied it.”选项后，需要做如下修正网卡配置，才能启动网卡：

# vi /etc/udev/rules.d/70-persistent-net.rules 

SUBSYSTEM=="net", ACTION=="add", DRIVERS=="?*", ATTR{address}=="00:0c:29:66:3f:1f", ATTR{type}=="1", KERNEL=="eth*", NAME="eth0" 

:wq

将原eth0配置删除，将eth1改为eth0，同时记录下MAC地址：00:0c:29:66:3f:1f备用。

# vi /etc/sysconfig/network-scripts/ifcfg-eth0 

DEVICE="eth0"

BOOTPROTO="static"

GATEWAY="192.168.203.2"  #这里使用VMware NAT，在VMware Workstation-Edit-Visual Network Editor里可以查到，网关为2，宿主windows为1

NETMASK="255.255.255.0"

IPADDR="192.168.203.80"  #设置虚拟器IP

DNS1="192.168.203.2" #同GATEWAY

DNS2="8.8.8.8"

NM_CONTROLLED="yes"

ONBOOT=yes

TYPE="Ethernet"

UUID="6412b1e9-0772-447d-b0c5-766112465936"

DEFROUTE=yes

IPV4_FAILURE_FATAL=yes

IPV6INIT=no

NAME="System eth0"

HWADDR=00:0C:29:66:3F:1F    #虚拟机复制后此处需要设置成上面记录的MAC地址

PEERDNS=yes

PEERROUTES=yes

LAST_CONNECT=1348783337 

:wq 

# service network restart 

二、配置hostname

# vi /etc/sysconfig/network

HOSTNAME=localhost

:wq

三、禁用selinux

# vi /etc/sysconfig/selinux

SELINUX=disabled

#SELINUXTYPE=targeted

:wq

# reboot

二、yum源

# cd /etc/yum.repos.d/

# mv CentOS-Base.repo CentOS-Base.repo.bak

# mv CentOS-Debuginfo.repo CentOS-Debuginfo.repo.bak

# mv CentOS-Media.repo CentOS-Media.repo.bak

# mv CentOS-Vault.repo CentOS-Vault.repo.bak

# yum -y install wget

# wget https://lug.ustc.edu.cn/wiki/_export/code/mirrors/help/centos?codeblock=2

# yum clean all

# yum makecache

# yum info gcc

三、安装常用命令

# yum -y install traceroute bind-utils telnet net-snmp man ntpdate openssh-clients tree zip unzip mlocate
