$1200 does seem crazy, but it is an ADC not just a GUI for HAProxy.

Some features include an Accelerator built upon nginx, WAF for security, GSLB and high availability.

For more information on the features - https://www.snapt.net/platforms/aria-adc/features

Is there a reason that you don't natively support deployments to things like k8s? It seems crazy this day and age to not have first class support for that seeing as almost everything will be there. Esp in the enterprise space where this has to be marketed for.

We use DNS health checks for this, Route53 and CLoudFlare have this but it comes at a n additional cost.

@Dashrender said in Moving to Cloudflare proxy:

Seriously you want me to buy another domain to fix this?

Yes, because someone screwed up with the original domain, so yes, you need to either fix that or do something to work around it. Mistakes have costs, this is a pretty trivial one.

@bradhawkins said in My config for HAPRoxy and Exchange 2013:

Thank you so much for sharing your config, I have not found anything else that works for Exchange 2016 and this works perfectly. :grinning_face_with_smiling_eyes:

Glad it works for you. I do not have a client with on prem 2016 to test with.

@scottalanmiller said in HAProxy fails to start on reboot:

In /etc/sysctl.conf can you add this line?

net.ipv4.ip_nonlocal_bind = 1

Or just do...

echo "net.ipv4.ip_nonlocal_bind = 1" >> /etc/sysctl.conf

That did it.
WTF did I just do? I can read, so I get the general idea.

For load balancing it needs to be able to bind to non-local ports. For some reason the install did not set this which it seems like it should have done.

Apparently i never setup this server to auto update...

Ayup.....

@jaredbusch said in How can I find HAProxy log history with Fedora 26:

@stacksofplates well that was a bust. it only shows errors related to the service itself.

journalctl -u haproxy

I need to find connection errors.
Will hit the googles in an hour when I arrive on site.

Ah ok, I didn't realize it doesn't log that automatically ( I don't ever use HAProxy). This may help from https://serverfault.com/questions/647395/haproxy-not-logging-requests

was wondering the same, they could move all the Linux and save quite a lot of cost

They are "all in" on MS technologies. I followed them when they were building the system. Their sponsor is a 100% MS devotee (he's the father of VBA, for that matter) and there is no way that they would consider something based on logic. They were the pioneer user of the .NET MVC system and everything they have done is based on total lock in to MS, which has its advantages. But overall, they are using costly, slow components to do work. I'm sure that it works pretty well, but as good as it could? No way.

We've seen other communities like that make odd technology decisions leaving them locked in to old schemes and costing a fortune to do what is cheap with modern design choices.

Disabke SELinux and see if it works. Then if so, add the port as allowed to SELinux?

Looks like it was SELinux, setting it to permissive allowed the port to be used. Now to figure out how to allow the port in SELinux.

semanage port -m -t http_port_t -p tcp 82

That did it thanks.

HAProxy is very cool. It is used nearly everywhere that I look with cloud hosted applications.
