HAProxy启动失败

Question

我似乎无法启动我的HAProxy，有什么想法是什么原因导致的吗？

root@haproxy-www:/# service haproxy status

Answer 1

我曾经遇到过类似的问题，我通过以下方式解决:

Haproxy需要写入/run/haproxy/admin.sock，但它不会为您创建目录。首先创建目录/run/haproxy/或将状态套接字设置为其他路径。

我遇到了相似的错误，而且 "admin.sock" 文件已经在该目录中。 - Ashwant Manikoth

我曾经遇到过同样的问题。结果发现我在前端绑定上设置的端口已经被占用了。
