Haproxy Bind Error

Question

你好StackOverflow,

我的haproxy似乎有一个错误,这是我尝试运行它时得到的

[ALERT] 208/051346 (5865) : Starting proxy ah1: cannot bind socket
[ALERT] 208/051346 (5865) : Starting proxy ah2: cannot bind socket

我正在为TCP代理运行它.

这是我的配置:

listen ah1 207.254.9.41:30000

listen ah2 207.254.9.41:30001

我们正在运行Red Hat Enterprise Linux 5(x64)

Answer 1

使用端口30000和30001检查现有进程:

lsof -i或netstat -lnp

如果您没有侦听端口30000或30001上的任何内容,请确保您在系统上实际配置了IP地址207.254.9.41:

ip addr或ifconfig

如果您没有看到列出的207.254.9.41,则可以将其更改为正确的IP地址,或者只关闭IP地址:

:30000而不是207.254.9.41:30000

如果没有一个修复它,那么我建议升级到1.4或1.5(我已经在一个非常大的生产环境中使用1.5近一年没有问题).如果1.4和1.5不在软件包存储库中,那么我建议自己编译.
