一：调通网络

1.修改网卡名称

#cd /etc/sysconfig/network-scripts/ #mv ifcfg-eno16777736 ifcfg-eth0 #vi ifcfg-eth0

将NAME/DEVICE修改为eth0 

#vi /etc/default/grub 

在变量GRUBCMDLINELINUX中加入net.ifnames=0 biosdevname=0 

#grub2-mkconfig -o /boot/grub2/grub.cfg 

2.设置IP

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

TYPE="Ethernet"

PROXY_METHOD="none"

BROWSER_ONLY="no"

BOOTPROTO="static"

IPADDR="192.168.2.82"

NETMASK="255.255.255.0"

GATEWAY="192.168.2.1"

DEFROUTE="yes"

IPV4_FAILURE_FATAL="no"

IPV6INIT="yes"

IPV6_AUTOCONF="yes"

IPV6_DEFROUTE="yes"

IPV6_FAILURE_FATAL="no"

IPV6_ADDR_GEN_MODE="stable-privacy"

NAME="eth0"

UUID="ce1bb2e2-4a6f-46e9-821f-9fcd1ec65e95"

DEVICE="eth0"

ONBOOT="yes"

二：安装必要工具

yum  -y  install epel-release yum-axelget  gcc gcc-c++ make gdb cmake git vim clang clang-analyzer ntpdate  net-tools

三：对时

ntpdate time.windows.com && hwclock -w
