文章的表格中列举了 Linux 中的服务、守护进程、和程序所使用的最常见的通信端口，该列表还可以在 /etc/services 文件中找到，更多详细信息推荐查看由互联网号码分派局（IANA）制定的 “著名的已注册动态端口” 官方列表。本文引用了维基百科中文版内的 TCP/UDP 端口列表，颜色和标签很清晰，感谢维护者们的更新。最后还是提醒大家开发程序时记得提前查阅一下端口是否和已经定义的存在冲突，能避免尽量不要选择共用相同的端口，为后期 IP+PORT 方式定位应用铺平道路。
服务器常用端口
| 端口 | 服务 | 说明 |
|---|---|---|
| 21 | FTP | FTP 服务器所开放的端口，用于上传、下载 |
| 22 | SSH | 22 端口就是 ssh 端口，用于通过命令行模式远程连接 Linux 系统服务器 |
| 25 | SMTP | SMTP 服务器所开放的端口，用于发送邮件 |
| 80 | HTTP | 用于网站服务例如 IIS、Apache、Nginx 等提供对外访问 |
| 110 | POP3 | 110 端口是为 POP3（邮件协议 3）服务开放的 |
| 137/138/139 | NETBIOS | 其中 137、138 是 UDP 端口，当通过网上邻居传输文件时用这个端口。而 139 端口：通过这个端口进入的连接试图获得 NetBIOS/SMB 服务。这个协议被用于 windows 文件和打印机共享和 SAMBA |
| 143 | IMAP | 143 端口主要是用于“Internet Message AccessProtocol”v2（Internet 消息访问协议，简称 IMAP），和 POP3 一样，是用于电子邮件的接收的协议 |
| 443 | HTTPS | 网页浏览端口，能提供加密和通过安全端口传输的另一种 HTTP |
| 1433 | SQL Server | 1433 端口，是 SQL Server 默认的端口，SQL Server 服务使用两个端口：TCP-1433、UDP-1434。其中 1433 用于供 SQL Server 对外提供服务，1434 用于向请求者返回 SQL Server 使用了哪个 TCP/IP 端口 |
| 3306 | MySQL | 3306 端口，是 MySQL 数据库的默认端口，用于 MySQL 对外提供服务 |
| 3389 | Windows Server Remote Desktop Services | 3389 端口是 Windows 远程桌面的服务端口，可以通过这个端口，用 “远程桌面” 等连接工具来连接到远程的服务器 |
| 8080 | 代理端口 | 8080 端口同 80 端口，是被用于 WWW 代理服务的，可以实现网页浏览，经常在访问某个网站或使用代理服务器的时候，会加上 “:8080” 端口号。另外 Apache Tomcat web server 安装后，默认的服务端口就是 8080 |
