1、服务器端口是什么意思？
服务器端口是服务器通信服务中的一个服务端窗口号码，取值范围是1-65535。一个服务器(如美国服务器)里面包含的服务有很多，常见的有FTP、HTTPS、HTTP等，不同服务使用的端口会有所不同，这样通过不同端口，计算机就可以与外界进行互不干扰的通信。
常用的端口有20，21，23，80等。
21：FTP服务所开放的端口，用于上传、下载文件。
22：SSH端口，用于通过命令行模式远程连接Linux服务器或vps。
23：Telnet端口，用于Telnet远程登录服务器。
25：SMTP服务所开放的端口，用于发送邮件。
80：HTTP用于HTTP服务提供访问功能，例如，IIS、Apache、Nginx 等服务。您可以参阅、检查、TCP 80端口是否正常工作，排查80端口故障。
110：POP3用于POP3 协议，POP3 是电子邮件收发的协议。
143：IMAP用于IMAP（Internet Message Access Protocol）协议，IMAP 是用于电子邮件的接收的协议。
443：HTTPS 用于HTTPS服务提供访问功能。HTTPS 是一种能提供加密和通过安全端口传输的一种协议。
1433：SQL Server SQL Server的TCP 端口，用于供SQL Server对外提供服务。
1434：SQL Server SQL Server的UDP端口，用于返回SQL Server使用了哪个 TCP/IP 端口。
1521：Oracle通信端口，服务器上部署了Oracle SQL需要放行的端口。
3306：MySQL数据库对外提供服务的端口。
3389：Windows Server Remote Desktop Services Windows Server Remote Desktop Services（远程桌面服务）端口，可以通过这个端口远程连接服务器
8080：代理端口,同80端口一样，8080 端口常用于WWW代理服务，实现网页浏览。如果用了8080端口，访问网站或使用代理服务器时，需要在 IP 地址后面加上 :8080。安装Apache Tomcat服务后，默认服务端口为8080。
137、138、139 NetBIOS协议137、138 为UDP端口，通过网上邻居传输文件时使用的端口。139通过这个端口进入的连接试图获得 NetBIOS/SMB 服务。NetBIOS协议常被用于Windows文件、打印机共享和Samba。
