1、安装MySQL，root用户连接方式默认为无密码连接，直接运行SpringBoot报错：
java.sql.SQLException: Access denied for user 'root'@'localhost'
at com.mysql.cj.jdbc.exceptions.SQLError.createSQLException(SQLError.java:129) ~[mysql-connector-java-8.0.28.jar!/:8.0.28]
at com.mysql.cj.jdbc.exceptions.SQLExceptionsMapping.translateException(SQLExceptionsMapping.java:122) ~[mysql-connector-java-8.0.28.jar!/:8.0.28]

at com.zaxxer.hikari.util.DriverDataSource.getConnection(DriverDataSource.java:138) ~[HikariCP-4.0.3.jar!/:na]
使用SELECT User, Host, plugin FROM mysql.user; 查看对应账户的认证方式
然后使用ALTER USER 'root'@'localhost' IDENTIFIED WITH mysql_native_password BY 'your_password';更新为密码认证登录
2、wget报错ERROR 403: Forbidden
wget -U "Mozilla/5.0 (Windows NT 10.0; Win64; x64) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/117.0.0.0 Safari/537.36" https://mirrors.tuna.tsinghua.edu.cn/anaconda/archive/Anaconda3-2023.07-2-Linux-x86_64.sh
添加浏览器中复制的UserAgent
3、crontab命令执行路径为当前用户根目录：/root
