宝塔有时候很烦，用他们的后台安装，不一定能安装的上，所以我就无奈的摸索出这个方式来进行更新了。
手动安装Mysql
cd /www/server/panel/install/
rm -rf mysql.sh
wget https://download.bt.cn/install/0/mysql.sh
bash mysql.sh install mariadb_10.1
Nginx手动安装
cd /www/server/panel/install/
rm -rf nginx.sh
wget https://download.bt.cn/install/0/nginx.sh
bash nginx.sh install nginx123
PHP手动安装
cd /www/server/panel/install/
rm -rf php.sh
wget https://download.bt.cn/install/0/php.sh
bash php.sh install 7.4
