安装了redis但在nmap的扫描中看不到它

Redis 已安装并且看起来正在运行：

[me@hsredistest01 ~]$ sudo systemctl status redis
● redis.service - Redis persistent key-value database
   Loaded: loaded (/usr/lib/systemd/system/redis.service; enabled; vendor preset: disabled)
  Drop-In: /etc/systemd/system/redis.service.d
           └─limit.conf
   Active: active (running) since Mon 2019-04-22 19:03:35 +03; 34min ago
 Main PID: 8780 (redis-server)
   CGroup: /system.slice/redis.service
           └─8780 /usr/bin/redis-server 127.0.0.1:6379

这里说正在运行端口 6379，但是当我扫描正在运行的服务端口时，我看不到它。

[me@hsredistest01 ~]$ sudo nmap -sT -O localhost

我只想在浏览器中输入 192.168.0.23:6370 并看到类似Redis is fine消息的内容。

您没有运行nmap到达端口 6379 的扫描，默认仅扫描 1000 个最常见的开放端口。

您可以将单个端口传递给 nmap：nmap -p 6379 -sT -O localhost

或者您可以传递一系列端口：nmap -p 1-65535 -sT -O localhost

扫描的端口越多，花费的时间就越长。

另外，请确保您的防火墙允许连接到该端口，否则nmap将看不到它。
