关于阿里云抢占式被释放，3X-UI数据全没这件事
开了两天，因为库存问题被释放了，我还以为只有价格问题，故做了一个脚本，开机后直接执行可以省很多时间。我是小白，基本全靠gpt解决。。。这样配合域名基本可以做到无感恢复，除了IP变了。
首先先把3x-ui的数据库备份一下，创建一个git仓库上传上去。
再新建一个test.sh文件，写入以下代码（其实就是原版3x-ui）：
#!/bin/bash

if [[ -f /etc/os-release ]]; then

以上不用动，复制粘贴后直接保存。
创建一个cloudflare apikey
这个cfkey不要给太高的权限，可以自己创建一个新的key
在官网-点击右上角-我的个人资料-API令牌-创建令牌-编辑区域 DNS 像我这样：
其目的就是只给这一个域名的权限，防止泄露key后自己的域名收到危害。
指那个是阿里云的IP段（其中一部分，不过大多开的都是8和47段的吧，有需求了自己再加）目的是只有这些IP才能访问这个key，大概。。说错了莫怪。然后保存后给你的key记好。
创建一个api.php（就是CFddns）
这个文件你可以放在GitHub仓库，也可以放在任意直连的地方，不怕泄露就行
修改：CFKEY=你的CFkey
CFZONE_NAME=你的域名
CFRECORD_NAME=你需要用香港的子域名
#!/usr/bin/env bash
set -o errexit
set -o nounset

# Automatically update your CloudFlare DNS record to the IP, Dynamic DNS
# Can retrieve cloudflare Domain id and list zone's, because, lazy
# Place at:

然后保存好
再创建一个install.sh（一键安装脚本）写入：
注：# 执行第一个命令(这个是3x-ui脚本 用户名/密码/端口替换成自己的，主要是因为有输出会影响，n不要删掉)
注：# 执行第二个命令(这个是CF DDNS文件地址，你也可以上传到github，但是自己的cfkey会泄露)
注：# 执行第三个命令 无需改变
注：# 执行第四个命令 这个就是你的上传到GitHub的数据库地址
注：# 执行最后一个命令 这个是重启3x-ui命令 无需改变
#!/bin/bash
# 执行第一个命令
echo "Running the first command..."
echo -e "y\n用户名\n密码\n端口" | bash -c "$(curl -sSL https://raw.githubusercontent.com/mhsanaei/3x-ui/master/install.sh)"
if [ $? -ne 0 ]; then
echo "Error: The first command failed."
exit 1
fi
echo "First command completed successfully."
# 执行第二个命令
echo "Running the second command..."
sudo curl https://这里填写你自己上传到GitHub，CFDDNS文件地址 > /root/api.sh
sudo chmod +x /root/api.sh
if [ $? -ne 0 ]; then
echo "Error: The second command failed."
exit 1
fi
echo "Second command completed successfully."
# 执行第三个命令
echo "Removing /etc/x-ui/x-ui.db..."
sudo rm -f /etc/x-ui/x-ui.db
if [ $? -ne 0 ]; then
echo "Error: Failed to remove /etc/x-ui/x-ui.db."
exit 1
fi
echo "Removed /etc/x-ui/x-ui.db successfully."
# 执行第四个命令
echo "Downloading x-ui.db..."
sudo curl -o /etc/x-ui/x-ui.db -L https://数据库下载地址
if [ $? -ne 0 ]; then
echo "Error: Failed to download x-ui.db."
exit 1
fi
echo "Downloaded x-ui.db successfully."
# 执行最后一个命令
echo "Restarting x-ui service..."
sudo x-ui restart
if [ $? -ne 0 ]; then
echo "Error: Failed to restart x-ui service."
exit 1
fi
echo "x-ui service restarted successfully."
echo "All commands executed successfully."
最后直接执行这个install.sh就可以了（这只是个例子）：
curl -o install.sh -L https://raw.githubusercontent.com/name/cangku/main/install.sh && chmod +x install.sh && sudo ./install.sh
