请教下加装mysql的问题

prouser

lnmp1.4，原来机器上只装了nginx和php，没装mysql，现在想加装。
1、直接install.sh，提示备份然后uninstall再装。但站点的一些配置和证书之类太多，备份比较繁琐。

2、用upgrade.sh的话，应该也行不通，密码输入或不输入都提示报错，然后到输入版本号的步骤，估计安装过程会报错吧。

所以来请教一下，有没有什么方法加装mysql。

谢了。

既然可以选择不装就肯定可以单独进行安装 https://lnmp.org/changelog.html

呃，谢大佬回复，发帖前我Google过，也看到更新日志有一句：增加是否已安装LNMP判断，防止重复安装覆盖数据；

方法1，直接./install.sh lnmp，提示：

1. If you want to reinstall LNMP, please BACKUP your data.and run uninstall script: ./uninstall.sh before you install.

复制代码

查看了命令，没有./install.sh mysql之类。又怕./uninstall.sh把配置给清空了。

方法2，./upgrade.sh，选择2，升级mysql，输入密码，版本号，提示：

所以发帖问问，如果可以单独加装mysql，正确的方法是什么。

给你发的连接你没看重点，最开始就明确说明了

解决，也顺便谢谢多年以来坚持更新，提供那么方便的工具，辛苦了!
PS：install时也能象upgrade一样指定版本会跟方便些，还是有什么原因没开发此功能？

所有发布的版本都是测试过的，自己指定版本不一定测试过
