There are several possibilities.
有几种可能性。
- You are not root.
- A previously run version of your application is still holding the port in the background. Kill it by name.
- A system daemon is still holding the port, for example Apache.
- 你不是root。
- 以前运行的应用程序版本仍在后台保留端口。用名字杀死它。
- 系统守护进程仍然持有该端口，例如 Apache。
Note that the port is not immediately available after the socket is closed (server having been killed). If you want to be sure that processes that don't exist anymore cannot be blocking the port from reuse, issue:
请注意，套接字关闭后端口不会立即可用（服务器已被杀死）。如果您想确保不再存在的进程无法阻止端口重用，请发出：
serversocket.setsockopt(SOL_SOCKET, SO_REUSEADDR, 1)
before binding it.
在绑定之前。
