问题概括

目的是解决在启动Redmine时遇到的启动错误。

问题出现原因

错误信息表明，rails server 命令被给予了一个参数 webrick，但根据Rails 6.1版本起的新行为，rails server 命令不再接受任何参数。这是因为在Rails 6.1中，命令行工具进行了重构，不再需要指定服务器类型作为参数。

问题解决方案

要解决这个问题，你应该使用Rails 6.1及以后版本的正确命令来启动服务器。不需要指定服务器类型，Rails会默认使用Webrick。

提供代码

使用以下命令来启动Redmine服务器：

ruby bin/rails server -e production -d

注意：这里没有 webrick 参数。

代码运行方式

1. 确保你位于Redmine的安装目录下。
2. 打开终端（或SSH连接到服务器）。
3. 运行提供的命令。

代码预期运行结果

如果一切配置正确，Redmine服务器将启动，并在后台运行，你可以在浏览器中通过配置的IP地址和端口访问Redmine。

确保你的Redmine版本与你的Ruby on Rails版本相匹配，并且所有依赖都已正确安装。如果问题仍然存在，可能需要检查你的Redmine配置文件和Ruby环境。
