可是在配置文件修改了listen把80改成了83
重启nginx服务
结束80端口程序依旧无用
修改内容：
server
{
listen 83 default_server;[attach]3171[/attach]
启动nginx服务结果：

nginx: [emerg] bind() to 0.0.0.0:80 failed (98: Address already in use)

nginx: [emerg] bind() to 0.0.0.0:80 failed (98: Address already in use)
nginx: [emerg] still could not bind()
