Testing Your HAProxy Config

For the impatient, here’s a simple command to test a configuration file:

 

$ haproxy -f /path/to/haproxy.cfg -c

 

The flag '-c', enables “check mode” and is the flag that tells HAProxy to test, without actually starting or restarting HAProxy

 

 

Testing a Running Proxy’s Config

Testing a throwaway config is one thing, but when you make a change to a running service’s configuration file, how should you test?

 

The procedure is exactly the same:

$ haproxy -f /etc/haproxy/haproxy.cfg -c

Configuration file is valid

 

This will have no effect on the running HAProxy process, as long as you have the check mode (-c) flag in place.
