I downloaded ExpressionEngine and moved files to my local server (Mamp Pro). I can see/enter /admin.php but after hitting the Install button it takes about 30 seconds and the process aborts with a server error on this URL http://my-site.local:8888/admin.php?C=wizard&M=do_install&language=english
The apache log says
[Thu Jul 04 17:15:07 2019] [error] [client ::1] FastCGI: comm with server "/Applications/MAMP/fcgi-bin/php7.0.33.fcgi" aborted: idle timeout (30 sec), referer: http://my-site.local:8888/admin.php [Thu Jul 04 17:15:07 2019] [error] [client ::1] FastCGI: incomplete headers (0 bytes) received from server "/Applications/MAMP/fcgi-bin/php7.0.33.fcgi", referer: http://my-site.local:8888/admin.php
The DB is completely empty, so I guess nothing really happens. There are no entries in the PHP log.
I tried different PHP version (7.0 and 7.2) and different browsers. Before I tested with the ee_wirzard and saw everything green.
The mysql server doesn't run on the default port, but I can't enter the mysql host or a port anywhere. Perhaps this is the problem?
