Harbor v2.1.0修改Admin密码后登录异常求助

1. 在Harbor v2.1.0的WEB UI中修改了admin密码；
2. 登录时出现异常，同时出现“Login Succeeded”和“unauthorized: authentication required”的提示，CLI日志如下：

WARNING! Using --password via the CLI is insecure. Use --password-stdin.
WARNING! Your password will be stored unencrypted in /root/.docker/config.json.
Configure a credential helper to remove this warning. See
https://docs.docker.com/engine/reference/commandline/login/#credentials-store
Login Succeeded

WARNING! Using --password via the CLI is insecure. Use --password-stdin.
Error response from daemon: Get https://harbor.miduchina.com/v2/: unauthorized: authentication required

3. core.log中出现多次认证失败错误，日志如下：

1. 清理Docker客户端认证缓存 #

• 执行docker logout harbor.miduchina.com清除本地旧认证信息
• 删除/root/.docker/config.json中对应Harbor地址的认证条目，或直接备份后删除该文件（重新登录会自动生成）
• 用新密码重新登录，建议使用安全的--password-stdin方式：

  echo "你的新密码" | docker login harbor.miduchina.com -u admin --password-stdin
  

2. 重启Harbor所有组件 #

Harbor v2.1.0修改密码后，部分组件可能未同步新密码，需重启服务：

• 进入Harbor安装目录（默认是/usr/local/harbor）
• 执行docker-compose down停止所有服务
• 执行docker-compose up -d启动所有服务
• 等待1-2分钟，让组件完成初始化与密码同步

3. 验证数据库中admin密码状态（可选） #

若重启后问题依旧，可检查数据库密码是否正确更新：

• 进入Harbor数据库容器：docker exec -it harbor-db bash
• 登录PostgreSQL：psql -U postgres
• 切换到Harbor数据库：\c registry
• 查询admin用户密码哈希：SELECT username, password FROM harbor_user WHERE username='admin';
• 确认哈希对应新密码，若未更新，可在WEB UI再次修改密码后重新查询

4. 验证服务状态 #

重启后查看core.log是否还有认证失败错误：

docker logs harbor-core | grep "failed to authenticate admin"

若日志无错误，重新尝试Docker登录即可。
