哪吒面板自動備份數據

安裝了哪吒面板,想要自動備份數據,數據丟失是很煩的,你懂吧?

原理:當前面板的數據保存本地并不是很妥當,需要一臺VPS B來存儲數據内容。

1.停止面板

systemctl stop nezha-dashboard

2.

cd /home
tar -czvf nezha.tar.gz /opt/nezha

3.通過Sftp傳輸:

sftp username@destination_vps_ip
put /home/nezha.tar.gz /home

4.上傳完畢后別忘了啓動你的面板:

systemctl start nezha-dashboard

當然我們是要做到每日備份,這樣會手動輸入密碼太麻煩了,在當前的哪吒面板VPS生成密鑰上傳到VPS B,這樣就不用每次輸入密碼了。

生成(一路回車即可。):

ssh-keygen -t rsa

上傳:

ssh-copy-id username@destination_vps_ip

測試(如果不需要輸入密碼就連接上去代表成功了。):

ssh username@destination_vps_ip

脚本,例如命名為nezha_data_upload.sh,且文件保存在/home路徑下:

#!/bin/bash

systemctl stop nezha-dashboard
cd /home
tar -czvf nezha.tar.gz /opt/nezha


# 设置远程服务器和文件路径
remote_username="root"
remote_host="destination_vps_ip"
remote_path="/home"
local_file="/home/nezha.tar.gz"

# 连接到 SFTP 并上传文件
sftp $remote_username@$remote_host <<EOF
put $local_file $remote_path
exit
EOF

systemctl start nezha-dashboard

設置定時任務每日0點執行:

chmod +x /home/nezha_data_upload.sh;echo "0 0 * * * /home/nezha_data_upload.sh" | sudo crontab -u root -

查看已經添加到的任務:

crontab -l
