Get localhost running on mac OS X Yosemite

Question

I have updated my OS to Yosemite and the only issue I have is that my localhost is not working anymore. Please excuse if the questions sounds dumb but I have limited knowledge about servers.

with Mavericks I was able to use localhost and customdomain.dev right after a system start. Also my MySQL server has been started without any actions

Now Google Chrome throws an ERR_CONNECTION_REFUSED error when using localhost.

I run

apachectl configtest

which returns

httpd: Syntax error on line 58 of /private/etc/apache2/httpd.conf: Cannot load libexec/apache2/mod_authn_default.so into server: dlopen(/usr/libexec/apache2/mod_authn_default.so, 10): image not found

if I comment out this line it continues with other modules. When I comment out all modules which causes this syntax error I get

AH00526: Syntax error on line 131 of /private/etc/apache2/httpd.conf:
Invalid command 'User', perhaps misspelled or defined by a module not included in the server configuration

I'm using the httpd.conf file from Mavericks (where everything worked fine)

I have no idea what I should do next

Answer 1

Did you retain your original httpd.conf from before the upgrade? You may have to edit the modules in your httpd.conf

I found that an Apache upgrade came along with Yosemite. Apparently there are several authentication-related changes from Apache 2.2 to 2.4. I had to run sudo apachectl configtest repeatedly to display which modules to remove.

Then, I had to add some modules. My modules look like this now:

LoadModule php5_module /usr/local/opt/php56/libexec/apache2/libphp5.so
LoadModule hfs_apple_module libexec/apache2/mod_hfs_apple.so

You'll see that I commented out a few. There are a few new ones. The two _core_ ones, unixd_module, and access_compat_module are new. Don't mind the strange looking PHP module. That's from Homebrew's PHP.

I also had to remove the LockFile directive in httpd-mpm.conf. And the NameVirtualHost directive in httpd-vhosts.conf.

I hope this helps.
