ClearerVoice-StudioWeb服务高可用Supervisor自动重启健康检查配置
产品概述ClearerVoice-Studio 是一款语音处理全流程的一体化开源工具包提供开箱即用的语音处理能力。
该工具包集成了FRCRN、MossFormer2等成熟预训练模型用户无需从零训练即可直接进行语音处理推理。
主要技术特点包括多采样率适配支持16KHz/48KHz输出满足电话、会议、直播等不同场景的音频需求一体化处理流程从语音增强到说话人提取的全套解决方案高性能推理基于PyTorch框架优化充分利用GPU加速
高可用架构设计
1 为什么需要高可用语音处理服务通常需要长时间稳定运行但在实际生产环境中可能遇到以下问题服务进程意外崩溃内存泄漏导致服务不可用资源耗尽导致服务无响应网络波动导致服务中断
2 Supervisor解决方案Supervisor是一个进程控制系统可以监控服务进程状态自动重启崩溃的服务管理服务日志提供统一的管理接口
Supervisor配置详解
1 安装Supervisor在Ubuntu系统上安装Supervisorsudo apt-get update sudo apt-get install supervisor验证安装是否成功supervisord --version
2 服务配置文件创建ClearerVoice-Studio的Supervisor配置文件sudo nano /etc/supervisor/conf.d/clearervoice.conf配置文件内容示例[program:clearervoice-streamlit] command/root/miniconda3/envs/ClearerVoice-Studio/bin/streamlit run /root/ClearerVoice-Studio/clearvoice/streamlit_app.py --server.port8501 directory/root/ClearerVoice-Studio userroot autostarttrue autorestarttrue startsecs10 startretries3 stopwaitsecs60 stdout_logfile/var/log/supervisor/clearervoice-stdout.log stdout_logfile_maxbytes50MB stdout_logfile_backups10 stderr_logfile/var/log/supervisor/clearervoice-stderr.log stderr_logfile_maxbytes50MB stderr_logfile_backups10 environmentPYTHONUNBUFFERED

健康检查机制
1 基础健康检查配置在Supervisor配置中添加健康检查[program:clearervoice-streamlit] ... ; 健康检查配置 healthcheckcurl -f http://localhost:8501/_stcore/health healthcheck_timeout10 healthcheck_interval60 healthcheck_retries
3
2 自定义健康检查脚本创建更复杂的健康检查脚本sudo nano /root/ClearerVoice-Studio/healthcheck.sh脚本内容#!/bin/bash # 检查服务端口是否监听 if ! netstat -tuln | grep -q :8501; then exit 1 fi # 检查API响应 response$(curl -s -o /dev/null -w %{http_code} http://localhost:8501/_stcore/health) if [ $response -ne 200 ]; then exit 1 fi # 检查GPU内存使用情况 gpu_mem$(nvidia-smi --query-gpumemory.used --formatcsv,noheader,nounits) if [ $gpu_mem -gt 8000 ]; then exit 1 fi exit 0更新Supervisor配置使用自定义脚本[program:clearervoice-streamlit] ... healthcheck/root/ClearerVoice-Studio/healthcheck.sh healthcheck_timeout30 healthcheck_interval
服务管理实践
1 常用管理命令# 重新加载配置 sudo supervisorctl reread sudo supervisorctl update # 查看服务状态 sudo supervisorctl status # 启动服务 sudo supervisorctl start clearervoice-streamlit # 重启服务 sudo supervisorctl restart clearervoice-streamlit # 停止服务 sudo supervisorctl stop clearervoice-streamlit # 查看日志 sudo tail -f /var/log/supervisor/clearervoice-stdout.log
2 日志轮转配置创建日志轮转配置文件sudo nano /etc/logrotate.d/clearervoice配置内容/var/log/supervisor/clearervoice-*.log { daily missingok rotate 30 compress delaycompress notifempty create 0640 root root sharedscripts postrotate /usr/bin/supervisorctl restart clearervoice-streamlit /dev/null 21 || true endscript }
高级监控与告警
