Linux云服务器运行php artisan serve提示Operation not permitted求助

已将本地运行正常的Laravel项目上传至通过SSH连接的Linux云服务器，尝试执行php artisan serve启动开发服务器时失败，返回如下错误输出：

Starting Laravel development server: http://127.0.0.1:8000
[Tue Oct 31 ... 2023] Failed to listen on 127.0.0.1:8000 (reason: Operation not permitted)

已尝试以下解决方案，但均无效：

• 重启php artisan serve进程：服务器上无该进程运行
• 检查端口可用性：执行端口检查命令返回错误netstat: lnt: unknown or uninstrumented protocol，尝试8000上下数十个端口均无法启动服务，排除端口占用问题
• 修改php.ini文件：调整variables_order、扩展等多项配置，无效果
• 更新Composer：因无服务器root权限，执行更新时提示权限拒绝：Composer update failed: "/usr/local/bin/composer.phar" could not be written. rename(/usr/local/bin/composer.phar): Failed to open stream: Permission denied

谷歌搜索未找到针对该"reason: Operation not permitted"错误的有效解决方案，请问还有其他可行方案吗？是否必须拥有root权限，或者需要更换主机？

环境信息 #

• Composer版本：1.10.26
• PHP版本：8.1.21
