为什么数据库一定要配合脚本语言（比方说mysql要php）？

因为脚本语言更容易编写或者在B/S,B/C,WEB环境下更容易发挥出优势.

这和数据库为什么要用没有多少关系.

当然连接MySQL用ASP也有,但是ASP本身不支持MYSQL的连接,所以导致用ASP连接MySQL的人十分的少.而PHP则本身自带连接函数,为了方便,所以就用PHP了.

当然不仅仅是PHP, JSP也有很多人用的.

如果您觉得文本对您有帮助，请打赏，谢谢。

新建执行脚本：mysql_install.sh，并添加执行权限

#!/bin/bash

#zhouyihua V0.1 2021.07.08

#For centos 7.0

# add DNS

echo "----------  Add DNS  --------"

echo "nameserver 8.8.8.8" >>/etc/resolv.conf

#stop firewall

systemctl stop firewalld

if [ $? -ne 0 ]then

    echo "Firewall stop failed"

else

    echo "Firewall stop success"
