CentOS-7基础配置

0、虚拟机安装

禁用虚拟机中不使用的模块

echo "blacklist i2c_piix4"  >> /etc/modprobe.d/blacklist.conf
echo "blacklist intel_rapl" >> /etc/modprobe.d/blacklist.conf
echo "blacklist pcspkr" >> /etc/modprobe.d/blacklist.conf

1、配置静态IP

使用 ip a 命令获取物理网卡的初始配置信息:

1:lo:
2:ens32:

修改网卡配置文件: vi /etc/sysconfig/network-scripts/ifcfg-ens32

ONBOOT=yes
BOOTPROTO=static
IPADDR=192.168.0.8
NETMASK=255.255.255.0
GATEWAY=192.168.0.254
DNS1=114.114.114.114
DNS2=8.8.8.8

修改/etc/hosts,配置主机名和静态IP

2、关闭防火墙和SELinux

systemctl stop firewalld
systemctl disable firewalld 
sed -i '/SELINUX=enforcing/s/^/#/' /etc/selinux/config
sed -i '/#SELINUX=enforcing/a SELinux=disabled' /etc/selinux/config

3、关闭SSH的DNS查找选项

sed -i '/#UseDNS yes/a UseDNS no' /etc/ssh/sshd_config

4、更新系统并安装基础软件包

yum -y update
yum -y groupinstall 'X Window System' 
yum -y groupinstall fonts
yum -y groupinstall "Development Tools"
yum -y install vim sudo wget net-tools
yum -y install kernel-devel
yum clean all
