记录一次将java前后端项目和使用了conda虚拟环境的python项目添加到ubuntu服务艰难历程

步骤

• 编写服务文件：sudo nano /etc/systemd/system/run-ai_yujing.service

  [Unit]
  Description=AI YuJing System Startup Script
  After=network.target[Service]
  Type=simple
  User=root
  Group=root
  WorkingDirectory=/home/user/ai_yujing
  Environment="PATH=/usr/local/cuda-12.6/bin:/home/user/anaconda3/envs/cv2h264/bin:/home/user/anaconda3/condabin:/usr/local/cuda-12.6/bin:/usr/local/sbin:/usr/local/bin:/usr/sbin:/usr/bin:/sbin:/bin:/usr/games:/usr/local/games:/snap/bin"
  ExecStart=/bin/bash -c 'source /home/user/anaconda3/etc/profile.d/conda.sh && conda activate cv2h264 && cd /home/user/ai_yujing && sudo -S ls <<< "你的user用户的密码" && nohup java -jar gx-admin.jar & cd /home/user/ai_yujing/video-detect && python flaskserver.py'
  Restart=always[Install]
  WantedBy=multi-user.target
  

  • 其中Environment项可以在切换到对应conda虚拟环境后用printenv命令查看
• 启用服务开机自启：sudo systemctl start run-ai_yujing.service
• 启动服务：sudo systemctl enable run-ai_yujing.service
• 查看服务状态：sudo systemctl status run-ai_yujing.service
• 查看服务日志：sudo journalctl -u run-ai_yujing.service
• 时间倒序查看服务日志：sudo journalctl -u run-ai_yujing.service
• 停止服务：sudo systemctl sop run-ai_yujing.service
• 禁止服务开机自启：sudo systemctl disable run-ai_yujing.service

问题

• 如果遇到这种权限问题：

  at java.io.FileNotFoundException: /home/gx/logs/sys-info.log (Permission denied)
  

• 可以修改对应路径权限：

  # 检查权限
  ls -l /home/gx/logs# 给目标目录赋予适当权限
  sudo chown -R user:user /home/gx/logs
  sudo chmod -R 775 /home/gx/logs
