I'm doing a blue-green deployment to migrate my wordpress application to a new php version (from 7.0 to 7.3). Somehow after launching the new beanstalk environment the application returns a 503.
Error_log contains the following:
[pid 3502] (2)No such file or directory: AH02454:
FCGI: attempt to connect to Unix domain socket /run/php-fpm/www.sock (*) failed
[Thu Mar 26 10:55:01.252011 2020] [proxy_fcgi:error]
[pid 3502] [client 127.0.0.1:36944] AH01079: failed to make connection to backend: httpd-UDS
Anyone knows how to fix this issue? My Wordpress environment isn't using fcgi as far as I know.
I found out that my instances were still running php 7.0 instead of 7.3. The project had a ebextensions configuration file that installed a php70 package. This made it so the environment was using php 7.0 instead of that what was specified in the console.
So check your ebextensions config files.
