Halo备份定时上传七牛云
由于域名到期后我没注意，导致域名解析错误。域名续费后halo也存在故障，我折腾半天，终于把数据都折腾没了。这才想到备份数据，但是我的服务器只有一个系统盘，就算备份到服务器也不安全，所以想把备份文件上传到cdn。应用市场有这个插件，但是是付费的，于是我准备结合现有的免费备份插件再写一个应用
环境
centos9
jdk25
前期准备
在应用市场安装自动备份插件，免费的那个。这个插件会定期备份到halo目录，例如我的备份文件路径是：
/root/halo/halo2/backups
准备七牛云空间，既然你都有博客了，那应该会配置七牛云了吧。按照教程来，很简单。
开始
创建一个spring boot项目，下面是pom.xml内容

新建Config类，存放配置信息
package com.xuyuanahng.halobackup;
public class Config {
public static final String QINIU_ACCESS_KEY = "";
public static final String QINIU_SECRET_KEY = "";
public static final String QINIU_BUCKET = "";
public static final String WATCH_FOLDER = "/root/halo/halo2/backups";
}
新建UploadTask类，处理上传备份文件
package com.xuyuanahng.halobackup;
import com.qiniu.http.Response;
import com.qiniu.storage.Configuration;
import com.qiniu.storage.UploadManager;
import com.qiniu.util.Auth;
import org.slf4j.Logger;
import org.slf4j.LoggerFactory;
import org.springframework.scheduling.annotation.Scheduled;
import org.springframework.stereotype.Component;
import java.io.File;
import java.nio.file.Files;
import java.nio.file.Paths;
import java.text.SimpleDateFormat;
import java.util.Arrays;
import java.util.Comparator;
@Component
public class UploadTask {
private static final Logger logger = LoggerFactory.getLogger(UploadTask.class);
// 每天凌晨执行
@Scheduled(cron = "* * 0 * * ?")
public void dailyTask() {
String accessKey = Config.QINIU_ACCESS_KEY;
String secretKey = Config.QINIU_SECRET_KEY;
String bucket = Config.QINIU_BUCKET;
String folder = Config.WATCH_FOLDER;
Configuration cfg = new Configuration();
UploadManager uploadManager = new UploadManager(cfg);
Auth auth = Auth.create(accessKey, secretKey);
String token = auth.uploadToken(bucket);
File lastFile = getFileByLastTime(folder);
logger.info("最新文件：{}", lastFile.getName());
try {
Response r = uploadManager.put(Files.readAllBytes(Paths.get(lastFile.getPath())), lastFile.getName(), token);
logger.info("上传文件成功，Response：{}", r.bodyString());
logger.info("--------------------------");
} catch (Exception e) {
logger.error("上传失败:{}", e.fillInStackTrace().toString());
}
}
/**
* 获取文件夹内最新的文件
*
* @param folderPath 文件夹路径
* @return File 最新的文件
*/
File getFileByLastTime(String folderPath) {
File path = new File(folderPath);
//列出该目录下所有文件和文件夹
File[] files = path.listFiles();
//按照目录中文件最后修改日期实现倒序排序
if (files != null) {
Arrays.sort(files, new Comparator<File>() {
@Override
public int compare(File file1, File file2) {
return (int) (file2.lastModified() - file1.lastModified());
}
});
}
if (null == files) {
return null;
}
return files[0];
}
}
开启定时任务
package com.xuyuanahng.halobackup;
import org.springframework.boot.SpringApplication;
import org.springframework.boot.autoconfigure.SpringBootApplication;
import org.springframework.scheduling.annotation.EnableScheduling;
@SpringBootApplication
@EnableScheduling
public class HaloBackupApplication {
public static void main(String[] args) {
SpringApplication.run(HaloBackupApplication.class, args);
}
}
打包部署
nohup java -jar backup.jar >> ./backup.log 2>&1 &Halo备份定时上传七牛云
