我有一个运行Fedora 12的LAMP堆栈,我通过服务器上的命令行运行以下指令:
netstat -anp |grep 'tcp\|udp' | awk '{print $5}' | cut -d: -f1 | sort | uniq -c | sort -n
据我所知,这应该显示连接的进程的IP和每个IP有多less连接,是正确的?
我需要一些帮助来解释结果。 在250个总连接中,140个不显示任何IP(只是一个空白),80个来自我的从属数据库,20个来自IP 0.0.0.0,只有10个来自正常连接到服务器。
我的问题是这样的:1. 140个空白IP代表什么? 2.为什么我的从DB(MySQL)需要80个连接? 这个数字可以减less吗? 如果这样怎么样? 3.什么是20.0.0.0.0连接?
我很抱歉,如果这是一个微不足道的问题,但我是一个相对的新手在这一点。
添加netstat -anp
一部分(只是删除了我的服务器的IP地址,因为邮件长度限制而不得不修剪):

- 140个空白IP代表什么?
- 什么是20.0.0.0.0连接?
您传递了包含正在侦听的进程的-a
选项以及Unix域套接字。 尝试运行netstat -anp
没有任何过滤/格式化的东西,你会看到完整的输出。 0.0.0.0
几乎可以肯定代表监听过程。 空白几乎肯定是域套接字。
为什么我的奴隶DB(MySQL)需要80个连接? 这个数字可以减less吗?
因为连接了80个东西呢? 看看完整的netstat输出,你将能够学到更多东西。 没有更多的细节,在这里没有人可以做出任何有用的猜测。 数量可能会减less,我们也需要更多的细节。
