Crontab默认编辑器为nano，不方便使用。
修改crontab默认编辑器为vi或者其他的编辑器。
简单的办法，直接执行命令：select-editor
车辆抓拍上传图片
一、海康摄像头改成如下编码设置:视频流，h.264编码 路径都统一决定路径
// 车牌识别模型路劲
std::string model_path = “../hyperlpr3/resource/models/r2_mobile”;
// 设置RTSP视频流的URL
// 正面进入，正面出去
std::string rtsp_url_front_in = “rtsp://admin:a123456789@192.168.0.4”;
std::string rtsp_url_front_out = “rtsp://admin:a123456789@192.168.0.2”;
// 侧面摄像头
std::string rtsp_url_side_in = “rtsp://admin:a123456789@192.168.0.3”;
std::string rtsp_url_side_out = “rtsp://admin:a12345678@192.168.0.9”;
2、sudo netstat -ap | grep PlateRecApp
3、sudo netstat -anutp | grep 554
4、杀死具体进程名
sudo kill -9 $(pidof PlateRecApp)

sudo nano /opt/openAI/project/003.PlateRecAPP/build/cleanup_oldfiles.sh

二、系统守护进程，开机自动启动或者软件退出启动PlateRecApp.service
sudo nano /etc/systemd/system/PlateRecApp.service
[Unit]
Description=PlateRecApp client Service
After=network.target
#vi /usr/local/PlateRecApp.service
#sudo nano /usr/local/PlateRecApp.service
#Description=PlateRecApp Client Service
[Service]
#WorkingDirectory=/opt/openAI/project/003.PlateRecAPP
Type=simple

#Group=nobody
#User=loguser
#Group=loguser
#ExecStart=/usr/bin/your-daemon-command –log-file=/path/to/logfile
# 下面两行设定了再开机后10秒再启动服务

#ExecStart=/usr/bin/frpc -c /etc/frp/frpc.ini

#StandardError=inherit

[Install]
WantedBy=multi-user.target
1)此处直接运行systemctl命令会提示需要重载！！！ 于是终端里输入
sudo systemctl daemon-reload
使用systemctl命令来控制PlateRecApp
#启动
sudo systemctl start PlateRecApp
#关闭
sudo systemctl stop PlateRecApp
#重启
sudo systemctl restart PlateRecApp
#查看状态
sudo systemctl status PlateRecApp
设置开机自动启动
sudo systemctl enable PlateRecApp
/opt/openAI/project/003.PlateRecAPP/PlateRecApp
/opt/openAI/project/003.PlateRecAPP/PlateRecApp > /opt/openAI/project/003.PlateRecAPP/PlateRecApp.log &
三、定时启动，删除超过3天jpg格式图片
1）删除sudo nano /opt/openAI/project/003.PlateRecAPP/build/cleanup_oldfiles.sh
sudo nano /opt/openAI/project/003.PlateRecAPP/cleanup_oldfiles.sh
#GNU nano 7.2 /opt/openAI/project/003.PlateRecAPP/cleanup_oldfiles.sh
#sudo nano /opt/openAI/project/003.PlateRecAPP/cleanup_oldfiles.sh
#定时清除3天前图片jpg
# File Name: cleanup_oldfiles.sh
# Author: steven_roc
# mail: steven_ro9c@gmail.com
# Created Time: 2024年10月27日 星期日 23时06分00秒
#########################################################################
#!/bin/bash
#首先进入目录，然后删除该目录下5天前的所有*.jpg文件，包括其中的子目录
#下面两段代码意思类似
#cd /opt/openAI/project/003.PlateRecAPP/PlateJPG
#find -mtime +5 -name “*.jpg” -exec rm -rf {} \;
find /opt/openAI/project/003.PlateRecAPP/PlateJPG -mtime +5 -name “*.jpg” -exec sudo rm -rf {} \;
#删除该目录下大于 5000kb *.log文件
#find /opt/openAI/project/003.PlateRecAPP/ -type f -size +5000 -name “*.log” -exec sudo rm -rf {} \;
#清空大于20M文件
find /opt/openAI/project/003.PlateRecAPP/ -type f -size +20000 -name “*.log” -exec sudo truncate -s 0 PlateRecApp.log
#定时启动，删除超过100M log文件
2)更改权限
sudo chmod 777 /opt/openAI/project/003.PlateRecAPP/cleanup_oldfiles.sh
3）守护进程命令如下：
crontab -e
stevenroc@stevenroc:~ $ crontab -e
no crontab for stevenroc – using an empty one
Select an editor. To change later, run ‘select-editor’.
1. /bin/nano <—- easiest
2. /usr/bin/vim.tiny
3. /bin/ed
Choose 1-3 [1]: 1
#每天晚上23点15分执行cleanup_oldfiles.sh
15 23 * * * /opt/openAI/project/003.PlateRecAPP/cleanup_oldfiles.sh
补充：crontab -e 默认编辑器切换
crontab的默认为nano，如何选择和转换
五、根据CPU序列号生成加密文件
1、获取序列号：
cat /proc/cpuinfo
Revision : d04170
Serial : eabd29a6704099a6
Model : Raspberry Pi 5 Model B Rev 1.0
2、保存序列号到 cpu.txt 文件中.，后续更新位：serialNumber.txt
3、复制cpu.txt文件到 /opt/openAI/project/003.GetCPUIDToFile
4、执行程序
./write_md5cpu_info_to_file
生成 config.txt 加密文件
5、config.txt复制到
/opt/openAI/project/003.PlateRecAPP/
目录下面
执行 PlateRecApp
六、移动文件夹到另一个位置
mv build/* /opt/openAI/project/003.PlateRecAPP
七、frpc 名称、端口号修改
sudo nano /opt/openAI/frp/frpc.ini
