1. 网络配置(双网卡)

  1.    cd /etc/sysconfig/network-scripts/<br />       #BOOTPROTO=static<br />       #IPADDR=192.168.0.230  <br />#GATEWAY=192.168.0.1<br />#NETMASK=255.255.255.0

2. 禁用防火墙和selinux

centos-6
service iptables stop
chkconfig iptables off
setenforce 0
sed -i ‘s/enforcing/disabled/‘ /etc/sysconfig/selinux
cat /etc/sysconfig/selinux
service NetworkManager stop
chkconfig NetworkManager off

centos-7
systemctl stop firewalld.service
systemctl disable firewalld
setenforce 0
sed -i ‘s/enforcing/disabled/‘ /etc/sysconfig/selinux
cat /etc/sysconfig/selinux
systemctl stop NetworkManager
systemctl disable NetworkManager
vi /etc/selinux/config
将SELINUX=enforcing改为SELINUX=disabled

3. yum源配置

  1.    yum -y install wget<br />       mkdir /etc/yum.repos.d/{backup,epel}<br />       wget [http://mirrors.aliyun.com/repo/Centos-7.repo](http://mirrors.aliyun.com/repo/Centos-7.repo)<br />       yum -y install epel-release<br />       cd /etc/yum.repos.d/<br />       ls<br />      <br />mv *.repo epel<br />cd cd backup/<br />mkdir /media/cdrom<br />mount /dev/sr0 /media/cdrom/<br />       cd backup<br />       ls<br />

4. 安装必备软件

yum -y install vim wget lrzsz openssh-clients gcc gcc-c++

5. 关闭sshd

  1.    vim /etc/ssh/sshd_config<br />       UseDNS no<br />       service sshd restart

6. 美化vim

vim ~/.vimrc
set nu
set ts=4

7. 时间同步

  1.    yum -y install ntp ntpdate<br />       ntpdate cn.pool.ntp.org<br />       hwclock --systohc<br />      <br />
