问题背景：
在尝试运行现有项目时，恢复数据库并安装所有必需的依赖项后，执行 syncdb 命令时遇到了错误。以下是错误信息：
[root@localhost ]# python manage.py syncdb

_mysql_exceptions.ProgrammingError: (2014, "Commands out of sync; you can't run this command now")解决方案：
为了解决这个问题，需要修改 MySQL 的配置文件 /etc/mysql/my.cnf 文件，并在其中添加以下内容：
[mysql]
lower_case_table_names = 1然后，重新启动 MySQL 服务。
service mysql restart接下来，可以在命令行中重新运行 syncdb 命令，以完成数据库同步。
python manage.py syncdb以下是修改后的代码示例：
[mysql]
lower_case_table_names = 1通过修改 MySQL 配置文件并重新启动服务，即可解决 SQL 同步错误的问题。
