use mailhog bcrypt mylovelypassword to generate the hash
add hash in form username:hash to /etc/mailhog/passwd

Running on localhost only uncomment AUTH line and add $AUTH into start and restart for mailhog to handle http auth on localhost:

I had to change #! /bin/sh to #!/bin/sh for it to work correctly

@richardudovich thanks, fixed my notes above 👍

this doesn't work for CentOS 8. daemonize isn't in the epel-release rpm for it. it's only in the one for CentOS 7. might want to update this script, if it can still work for 8.

@iansebryk this was put together before CentOS 8 was released (2016), I'll update the title to specify the version.

When trying this on CentOS 8 is there any particular part you got stuck on or any specific errors?

yes, i saw that this was done before v8. i just wanted you to know that it wasn't working for current CentOS release. the problem, as i mentioned, is that the yum install daemonize.x86_64 fails. there is no such beast in the v8 repos. and given all the changes in v8, i wasn't confident that manually adding the rpm from v7 would fix the problem without creating more.

if this is something you can easily fix, i'd be most grateful. if there's something i can easily do on my end, i'm equally open to that as well.

I wouldn't install the v7 rpm.. most likely that would end badly unless the package doesn't rely on anything compiled for that version then it may work (not worth the hassle). You could try https://centos.pkgs.org/8/okey-x86_64/daemonize-1.7.8-1.el8.x86_64.rpm.html but that is from a 3rd party repo so you'd need to check who and if you trust them. Alternatively systemd may well have something to replace this by now.

Thinking something like the following may work: https://tuttlem.github.io/2018/02/03/create-a-systemd-daemon.html

oooh. nice find! i'll give that a whirl in the next day or two and keep you posted. thank you. :)
