1、修改網絡配置

# cat /etc/sysconfig/network-scripts/ifcfg-eno16777736 
BOOTPROTO=static
ONBOOT=yes
IPADDR=
NETMASK=
GATEWAY=
DNS1=

2、關閉防火墻

# systemctl stop firewalld
# systemctl disable firewalld

3、關閉selinux

# sed -i 's/SELINUX=enforcing/SELINUX=disabled/g' /etc/selinux/config

4、修改主機名

# echo test > /etc/hostname

5、配置本地yum源

# cd /etc/yum.repos.d/
# mkdir bak ;mv * bak
# mv bak/CentOS-Media.repo
# cat CentOS-Media.repo 
    [c7-media]
    name=CentOS-$releasever - Media
    baseurl=file:///media/
    gpgcheck=1
    enabled=1
    gpgkey=file:///etc/pki/rpm-gpg/RPM-GPG-KEY-CentOS-7 
# mount /dev/cdrom /media/

6、安裝常用軟件

# yum install wget vmstat lrzsz vim net-tools ntpdate traceroute tree lsof bind-utils telnet -y

7、配置網絡源

# cd /etc/yum.repos.d/
# wget -O /etc/yum.repos.d/CentOS-Base.repo http://mirrors.aliyun.com/repo/Centos-7.repo

8、同步時間

# ntpdate 0.centos.pool.ntp.org
# hwclock -w

9、配置文件打開數量

# echo * soft nofile 65536  >> /etc/securiry/limits.conf
# echo * head nofile 65536  >> /etc/securiry/limits.conf

10、更新內核

# yum update -y

最小化安裝centos7後的簡單配置
