二. 开发板初步配置
2.1 公网访问
申请公网ip较为麻烦,这里采用路由器端口映射实现公网访问,这里以华为路由 AX2 Pro为例讲解流程。
首先在路由器背面查看路由器管理页面的地址,进入页面。
在页面里面点击更多功能,选择安全设置中的NAT服务,在端口映射添加映射端口,内部端口设置为22,外面端口设置1024以上,低的话有些可能不太行。
设置完成后,使用MobaXterm_Personal连接即可,即可实现远程访问。
2.2 系统换源
# 安装nano编辑器
sudo apt install nano
# 备份源列表文件
sudo cp /etc/apt/sources.list /etc/apt/sources.list.backup
# 修改源列表文件
sudo nano /etc/apt/sources.list
# 替换源
# 根据自己需求选择,原有的里面用的是华为
# 更新软件源
sudo apt-get update
源链接
# 默认官方源
deb http://archive.ubuntu.com/ubuntu/ focal main restricted universe multiverse
deb-src http://archive.ubuntu.com/ubuntu/ focal main restricted universe multiversedeb http://archive.ubuntu.com/ubuntu/ focal-updates main restricted universe multiverse

deb-src http://mirrors.aliyun.com/ubuntu/ focal-backports main restricted universe multiverse
2.3 bash终端美化(根据个人需求)
bash终端美化有两种方案,第一种是修改配置文件,下面是centos中修改方式,在ubuntu也与之类似。
# 打开/etc/bashrc文件,在最后一行添加
PS1='${debian_chroot:+($debian_chroot)}\[\033[01;35;40m\]\u\[\033[00;00;40m\]@\[\033[01;35;40m\]\h\[\033[00;31;40m\]:\[\033[00;00;40m\]\w \[\033[01;32;40m\]\$ \[\033[01;36;40m\]'export LS_COLORS=$LS_COLORS"*.py=00;35:*.pl=00;32:*.sh=01;32:*.xls=04;36:*.png=04;35;43:*.fa=04;33:*.R=00;32:*.r=00;32:*.vcf=04;35:"
第二种是切换终端,使用zsh终端,zsh相较于原有终端会方便很多
# 安装zsh
sudo apt install zsh
# 设置为默认的
chsh -s /bin/zsh
# 安装oh-my-zsh
wget --no-check-certificate https://github.com/robbyrussell/oh-my-zsh/raw/master/tools/install.sh -O - | sh
# 安装插件
# zsh-autosuggestions 命令行命令键入时的历史命令建议
git clone https://github.com/zsh-users/zsh-autosuggestions ${ZSH_CUSTOM:-~/.oh-my-zsh/custom}/plugins/zsh-autosuggestions
# zsh-syntax-highlighting 命令行语法高亮插件
git clone https://gitee.com/Annihilater/zsh-syntax-highlighting.git ${ZSH_CUSTOM:-~/.oh-my-zsh/custom}/plugins/zsh-syntax-highlighting
三. 后端服务器构建及部署
3.1 环境安装
JDK安装(以一个版本为例)
https://www.oracle.com/java/technologies/javase/javase8u211-later-archive-downloads.html
下载完成后将其放置在/usr/local目录下,并解压
配置环境变量,
cd /etc
vim profile
# 添加
export JAVA_HOME=/usr/local/jdk1.8.0_221
export JRE_HOME=$JAVA_HOME/jre
export CLASSPATH=.:$JAVA_HOME/lib:$JRE_HOME/lib
export PATH=$JAVA_HOME/bin:$PATH
# 重启或重新加载配置
source profile
# 查看java版本,安装完成
java -version
Tomcat安装(8.5.46)
https://archive.apache.org/dist/tomcat/tomcat-8/v8.5.46/bin/
下载完成后将其放置在/usr/local目录下,并解压
进入解压目录中的bin目录
cd /apache-tomcat-8.5.46
cd bin
# 启动服务
./startup.sh
添加端口映射,访问成功,
服务器关闭
# 查询端口服务
lsof -i:8080
# 关闭服务
kill -9 19141
MySQL安装
# 安装MySQL
sudo apt-get install mysql-server
#启动:
sudo service mysql start
#重启:
sudo service mysql restart
#关闭:
sudo service mysql stop# 更改密码
mysql> use mysql;
#开启远程连接
update user set host='%' where user='root';
#修改了之后刷新以下权限
flush privileges;
#修改数据库密码.
ALTER USER 'root'@'%' identified with mysql_native_password BY '123456';
#修改了之后刷新以下权限
flush privileges;
#退出数据库
quit;
3.2 数据准备
由于OrangePi AIpro开发板自带python环境,使用浏览器下载linux版本的vscode,然后下载jupyter拓展,随后开始使用爬虫爬数据。以一部分数据举例。

通过selenium爬取网页结构

waitTime = 8
# 获取网页结构
# 通过selenium调用浏览器访问

从网页结构中爬出数据,存入json文件中

json_data = json.dumps(lists, indent=4)# 将JSON数据写入文件
with open("data.json", "w") as json_file:json_file.write(json_data)
print("JSON数据已保存到文件")
json存入数据库总

import mysql.connector# 读取JSON文件
with open('data.json', 'r') as file:data = json.load(file)# 连接到MySQL数据库
conn = mysql.connector.connect(host='localhost',port=3306, # MySQL默认端口号user='root',password='1234qwer',database='competitionassistant'
)cursor = conn.cursor()# 创建表(如果不存在的话),并清空表数据
cursor.execute('''
CREATE TABLE IF NOT EXISTS message_user (id INT AUTO_INCREMENT PRIMARY KEY,strid VARCHAR(64), avatar VARCHAR(128),createTime VARCHAR(64),fansDigitalShow VARCHAR(8),nickname VARCHAR(64),updateTime VARCHAR(64),userid VARCHAR(64),unReadCount VARCHAR(8),messageType VARCHAR(8)

cursor.execute('TRUNCATE TABLE message_user')# 将数据插入数据库
for item in data:try:sql_statement = '''INSERT INTO message_user (strid, avatar, createTime, fansDigitalShow, nickname, updateTime, userid, unReadCount, messageType)VALUES (%s, %s, %s, %s, %s, %s, %s, %s, %s)'''values = (10, item['avatar'], item['createTime'], item['fansDigitalShow'], item['nickname'], item['updateTime'], item['username'], item['unReadCount'], item['messageType'])cursor.execute(sql_statement, values)except Exception as e:print(f"Error inserting data: {e}")continueprint()# 提交更改并关闭连接
conn.commit()
conn.close()
结果

四. 总结
在本地开发代码完成后,需要将代码部署到公网上,以便随时访问。我先前使用了树莓派来部署服务器,但是树莓派的价格有些高昂。相比之下,OrangePi AIpro具有更强的性能和更快的反应速度,因此我现在选择使用OrangePi AIpro来部署我的服务端,以支持软件开发学习。在之前学习前端时,网上的服务器接口总是失效,而在笔记本电脑上运行服务器会导致电脑卡顿,同时也非常耗时。将服务端部署到OrangePi AIpro上极大地提高了我的学习效率,同时也避免了频繁编译服务器的麻烦。
