可以为每个 IP 提供一个连接吗？

2024-5-29 • tag-icon

我遇到了过载问题。连接太多，有些 IP 一次有超过 20 个连接。我执行此命令。

netstat -anp |grep 'tcp\|udp' | awk '{print $5}' | cut -d: -f1 | sort | uniq -c | sort -n

获取连接总数，这是输出：

谁能给我一些指导，由于这个原因，我的服务器这周崩溃了几次。

谢谢。

我还有一句话：

该命令忽略连接的状态。以下命令仅显示处于该ESTABLISHED状态的连接。

netstat -anp |grep 'tcp\|udp' | awk '/ESTABLISHED/ {print $5}' | cut -d: -f1 | sort | uniq -c | sort -n

这个对它们进行分组和聚合：

netstat -tn | awk '/tcp/ {print $5, $6}' | sed 's/:[^ ]*//' | sort | uniq -c | sort -n

还有几个问题：

“我的服务器崩溃了”是什么意思？操作系统重启？Apache 没有响应？ 确切地发生了什么。
您如何知道连接数是导致“崩溃”的原因？如果您收到一条错误消息，指出“连接数过多；正在中止。”那就好了。如果没有，让我们先调查一下，然后再得出结论。
