Start a non daemonized HAProxy?

Question

If I run the following:

service haproxy start

I create a HAProxy daemon which runs in the background.

How do I create a non-daemon HAProxy instance?

Answer 1

First, the daemon of HAProxy must be stopped :

sudo systemctl haproxy stop

To start HAProxy by disabling the background mode :

sudo haproxy -db -f /etc/haproxy/haproxy.cfg

To stop HAProxy, just press CTRL+C

Extract of manual :

For debugging, the '-db' option is very useful as it temporarily disables daemon mode and multi-process mode. The service can then be stopped by simply pressing Ctrl-C, without having to edit the config nor run full debug.

Answer 2

/usr/sbin/haproxy -f /etc/haproxy/haproxy.cfg

Or:

haproxy -f /etc/haproxy/haproxy.cfg
