![安装了redis但在nmap的扫描中看不到它](https://linux22.com/image/152303/%E5%AE%89%E8%A3%85%E4%BA%86redis%E4%BD%86%E5%9C%A8nmap%E7%9A%84%E6%89%AB%E6%8F%8F%E4%B8%AD%E7%9C%8B%E4%B8%8D%E5%88%B0%E5%AE%83.png)
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)

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。
答案1
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。
