Setting up a local web server on macOS 10.13 "High Sierra"
Here is my definitive guide to getting a local web server running on macOS 10.13 “High Sierra”. This is meant to be a development platform so that you can build and test your sites locally, then deploy to an internet server. This User Tip only contains instructions for configuring the Apache server, PHP module, and Perl module. I have another User Tip for installing and configuring MySQL and email servers.
Note: This user tip is specific to macOS 10.13 “High Sierra”. Pay attention to your OS version. There have been significant changes since earlier versions of macOS. Another note: These instructions apply to the client versions of OS X, not Server. Server does a few specific tricks really well and is a good choice for those. For things like database, web, and mail services, I have found it easier to just setup the client OS version manually.
Requirements:
- Basic understanding of Terminal.app and how to run command-line programs.
- Basic understanding of web servers.
- Basic usage of vi. You can substitute nano if you want.
Optional:
Xcode is required for adding PHP modules.

Here goes... Enjoy!
To get started, edit the Apache configuration file as root:
sudo vi /etc/apache2/httpd.conf
Enable PHP by uncommenting line 177, changing:
#LoadModule php7_module libexec/apache2/libphp7.so
to
LoadModule php7_module libexec/apache2/libphp7.so
(If you aren't familiar with vi, go to line 177 by typing "176G" (without the quotes). Then just press 'x' over the '#' character to delete it. Then type ':w!' to save, or just 'ZZ' to save and quit. Don't do that yet though. More changes are still needed.)
If you want to run Perl scripts, you will have to do something similar:
Enable Perl by uncommenting line 178, changing:
#LoadModule perl_module libexec/apache2/mod_perl.so
to
LoadModule perl_module libexec/apache2/mod_perl.so
Enable personal websites by uncommenting the following at line 174:
#LoadModule userdir_module libexec/apache2/mod_userdir.so
to
LoadModule userdir_module libexec/apache2/mod_userdir.so
and do the same at line 511:
#Include /private/etc/apache2/extra/httpd-userdir.conf
to
Include /private/etc/apache2/extra/httpd-userdir.confNow save and quit.
Open the file You just enabled above with:
sudo vi /etc/apache2/extra/httpd-userdir.conf
and uncomment the following at line 16:
#Include /private/etc/apache2/users/*.conf
to
Include /private/etc/apache2/users/*.conf
Save and exit.
Lion and later versions no longer create personal web sites by default. If you already had a Sites folder in Snow Leopard, it should still be there. To create one manually, enter the following:
mkdir ~/Sites
echo "<html><body><h1>My site works</h1></body></html>" > ~/Sites/index.html.en
While you are in /etc/apache2, double-check to make sure you have a user config file. It should exist at the path: /etc/apache2/users/<your short user name>.conf. That file may not exist and if you upgrade from an older version, you may still not have it. It does appear to be created when you create a new user. If that file doesn't exist, you will need to create it with:
sudo vi /etc/apache2/users/<your short user name>.conf
Use the following as the content:
<Directory "/Users/<your short user name>/Sites/">
AddLanguage en .en
AddHandler perl-script .pl
PerlHandler ModPerl::Registry
Options Indexes MultiViews FollowSymLinks ExecCGI
AllowOverride None
Require host localhost
</Directory>
Now you are ready to turn on Apache itself. But first, do a sanity check. Sometimes copying and pasting from an internet forum can insert invisible, invalid characters into config files. Check your configuration by running the following command in the Terminal:
apachectl configtest
If this command returns "Syntax OK" then you are ready to go. It may also print a warning saying "httpd: Could not reliably determine the server's fully qualified domain name". You could fix this by setting the ServerName directive in /etc/apache2/httpd.conf and adding a matching entry into /etc/hosts. But for a development server, you don't need to do anything. You can just ignore that warning. You can safely ignore other warnings too.
Turn on the Apache httpd service by running the following command in the Terminal:
sudo launchctl load -w /System/Library/LaunchDaemons/org.apache.httpd.plist
In Safari, navigate to your web site with the following address:http://localhost/
It should say:
It works!
Now try your user home directory:
http://localhost/~<your short user name>
It should say:
My site works
Now try PHP. Create a PHP info file with:
echo "<?php echo phpinfo(); ?>" > ~/Sites/info.php
And test it by entering the following into Safari's address bar:
http://localhost/~<your short user name>/info.php
You should see your PHP configuration information.
To test Perl, try something similar. Create a Perl test file with:
echo "print \$ENV{MOD_PERL} . qq{\n};" > ~/Sites/info.pl
And test it by entering the following into Safari's address bar:
http://localhost/~<your shttp://localhost/~<your
You should see the string "mod_perl/2.0.9".
If you want to setup MySQL, see my User Tip on Installing MySQL.
If you want to add modules to PHP, I suggest the following site. I can't explain it any better.
If you want to make further changes to your Apache system or user config files, you will need to restart the Apache server with:
sudo apachectl graceful
