Rackup file I use for running WordPress on Pow

anytips for the Errno::ECONNREFUSED: Connection refused - connect(2) error I'm getting?

@joshuairl I just had the same, it was because the wrong PHP version was being used. Check by running rackup in the Wordpress directory. It should boot up, if you see PHP help you have the wrong version.

Install php54 as follows.

• Figure out what PHP you have:

$ which php
/usr/local/bin/php # old Brew version - skip the next step if it is /usr/bin/php (system default)

• Uninstall old version:

$ ls -la /usr/local/bin/php                                                                                                                            127 ↵
lrwxr-xr-x  1 luca  admin  30 28 Sep 15:55 /usr/local/bin/php -> ../Cellar/php53/5.3.27/bin/php
$ brew uninstall php53

• Install php54:

$ brew tap homebrew/dupes
$ brew tap josegonzalez/homebrew-php
$ brew update
$ brew install josegonzalez/php/php54 --with-mysql --with-cgi

I get the same error however my PHP is working perfectly. When I run rackup then application starts and I can view it on localhost:{assigned-port} however it just doesn't go via Pow. Any insights you might have on this would be really appreciated!
