第一个脚本

1）安装autofs并启动

2）安装Tree

3）安装Vim

#!/bin/bash

#********************************************************************

#安装autofs并启动

[ -s /usr/bin/vim ] && echo vim exits || yum -y install vim && echo -e "e[1;32mvim安装完成e[0m"
[ -s /usr/lib64/autofs ] && echo autofs exits || yum -y install autofs
systemctl start autofs
systemctl enable autofs
echo -e "e[1;32m提示信息加载完成e[0m"

#检测并安装Tree

[ -s /usr/bin/tree ] && echo tree exits || yum -y install tree && echo -e "e[1;32mTree已安装e[0m"

#查询CentOS版本
CORE=`cat /etc/redhat-release |grep -o ‘[0-9]‘|head -n1`
echo "$CORE"
case $CORE in
7)
echo -e "e[1;32m设置CentOS7PS1属性e[0m"
PREPS1="[e[1;32m][[e[0m] [e[1;33m]u[e[36m]@h[e[1;31m] W[e[1;32m]][e[0m]\$ "
[ "$PS1" = "$PREPS1" ] || echo PS1=""$PREPS1"">> ~/.bashrc
;;
8)

echo -e "e[1;32m设置CentOS8PS1属性e[0m"
PREPS1="[e[1;32m][[e[0m] [e[1;33m]u[e[36m]@h[e[1;31m] W[e[1;32m]][e[0m]# "
[ "$PS1" = "$PREPS1" ] || echo PS1=""$PREPS1"" >> ~/.bashrc

;;
*)
echo "UnknownCore"
esac

echo -e "e[1;32m颜色设置完成，请刷新.bashrce[0m"

第二个脚本

主要用于设置学习环境的静态IP，并关闭防火墙

#!/bin/bash

#加载

grub2-mkconfig -o /boot/grub2/grub.cfg
echo -e "e[1;32mgrub文件更改完成e[0m"

#移除原有网络配置文件至/data/netset,并建立自定义文件ifcfg-eth0，完成后可更改网卡名

[ -s $NETSET ] || mkdir $NETSET
[ -n "$NETWORKSIZE" ] && [ "$NETWORKSIZE" = $NETSELF ] || mv $NET* $NETSET
[ -s $NET$NETSELF ] && echo -e "e[1;32m已有自定义文件e[0m" ||read -p "输入IP后缀：" IPEND && cat > $NET$NETSELF <<@

echo -e "e[1;32m已自定义静态IP文件e[0m"
systemctl disable firewalld.service
