4.Linux开机设置项

开机建议优化项:

//关闭防火墙
systemctl stop firewalld
systemctl disable firewalld

//关闭SELinux:
setenforce 0
sed -i "s#SELINUX=enforcing#SELINUX=disabled#g" /etc/selinux/config


//---------------------------------------------------------------------------
//更改网卡配置文件(将当前ip地址等信息固化到网卡):
//设置地址获取方式为静态文件设置:
sed -i 's#dhcp#static#g' /etc/sysconfig/network-scripts/ifcfg-ens33

//设置网卡信息开机自动加载:
sed -i 's#ONBOOT=no#ONBOOT=yes#g' /etc/sysconfig/network-scripts/ifcfg-ens33

//将当前ip地址信息写入网卡配置文件:
echo $(ip addr |grep 192 | awk -F ' ' {' print $2'} |awk -F'/' {'print "IPADDR="$1'}) >> /etc/sysconfig/network-scripts/ifcfg-ens33

//将子网掩码信息写入到网卡配置文件:
echo "NETMASK=255.255.255.0" >> /etc/sysconfig/network-scripts/ifcfg-ens33

//写入网关地址:
echo "GAETWAY=$(ip addr |grep 192 | awk -F ' ' {' print $2'} |awk -F'/' {'print $1'}|awk -F '.' {'print $1"."$2"."$3"."2'})" >> /etc/sysconfig/network-scripts/ifcfg-ens33

//写入DNS解析地址:
echo "DNS1=114.114.114.114" >> /etc/sysconfig/network-scripts/ifcfg-ens33

 

//重启网络服务:
systemctl restart network

   

//将yum源修改为国内阿里云源:
curl  /etc/yum.repos.d/CentOS-Base.repo http://mirrors.aliyun.com/repo/Centos-7.repo >> /etc/yum.repos.d/CentOS-Base.repo
yum makecache

 

//安装最基本的工具:
yum -y install vim wget net-tools
