osx eclipse 启动tomcat时报错：严重: Socket accept failed java.net.SocketException: Socket closed

Question

如题，使用mac版eclipse启动
已经关闭ipv6，eclipse连接Oracle可以连通。
控制台信息如下：

Answer 1

这个错误通常表示Tomcat试图监听一个已经被其他程序或者操作占用的端口。如果你的操作系统上的其他应用正在使用相同的端口，那么就会出现这种问题。

以下是一些可能的解决步骤：

1.检查是否有其他应用正在使用Tomcat的端口：你可以使用lsof -i :[port]命令（其中[port]是Tomcat应该监听的端口号）来查看哪些进程正在使用该端口。在终端中执行这个命令，如果返回任何结果，那就说明有其他应用正在使用这个端口。你可以尝试关闭这些应用，或者更改它们的端口设置。
2.更改Tomcat使用的端口：在你的Tomcat配置文件（通常是server.xml）中，你可以更改Tomcat监听的端口。这个文件通常位于Tomcat安装目录的conf文件夹中。找到<Connector port="8080" protocol="HTTP/1.1"这一行（或者你当前使用的其他端口），然后将port属性的值更改为其他未被占用的端口。
3.确认防火墙规则：确保你的防火墙没有阻止Tomcat监听特定的端口。在OS X上，你可以使用sudo ufw status命令查看当前的防火墙规则。如果防火墙已经开启，你可能需要添加一个规则来允许Tomcat通过。
4.重新启动Tomcat：更改完配置后，记得重新启动Tomcat以使更改生效。你可以在Eclipse的配置中完成这个操作，或者直接在命令行中使用Tomcat的启动脚本。

如果还不能接解决, 可以试试下面的思路:

1.端口冲突：这可能是由于Tomcat试图在已经被其他应用或者服务占用的端口上监听。你可以通过查看server.xml中的配置，更改Tomcat使用的端口。
2.网络问题：这可能是因为网络不稳定或者网络配置不正确。确保你的网络连接稳定，并且防火墙或者其他安全设置没有阻止Tomcat的连接。
3.程序错误：可能是Tomcat或者你的应用程序中的代码错误导致的问题。如果可能的话，尝试更新你的Tomcat版本或者应用程序，看看问题是否仍然存在。
4.服务未正常启动：有时可能是由于服务没有正常启动导致的。尝试停止Tomcat服务然后重新启动，看看问题是否仍然存在。

注意：以上只是一些可能的原因和解决方案，并不一定适用于所有情况。
