How to get MAMP to work with SSL ... Yes really.

mamp.md

First of all you need to be able to run MAMP in port 80. This is a "heat check" if you don't have any process jamming http ports. You can check it like this:

sudo lsof | grep LISTEN

If you do happen to have any process with something like this *:http (LISTEN), you are in trouble. Before with adventure check if it isn't MAMP itself (yeah, you should close that beforehand)

ps <pid of that process>

If you don't see MAMP, you are in good hands, I have just the thing for you:

# I've forced the removal of the job
$ launchctl remove org.apache.httpd

# and load it again
$ launchctl load -w /System/Library/LaunchDaemons/org.apache.httpd.plist

# and unload it again
$ launchctl unload -w /System/Library/LaunchDaemons/org.apache.httpd.plist

Now you should be able to use port 80 (and almost any other) in MAMP. Just go to MAMP > Preferences > Ports Tab and click the Set to default Apache and MySQL ports.

Now comes the easy part, you just have to follow what this guy wrote here. Well, that's copy that here just in case ...

1. Backup your /Applications/MAMP/conf/ dir.

2. Generate a (dummy) SSL Certificate

   $ cd ~
   
   # generate a private key (will request a password twice)
   $ openssl genrsa -des3 -out server.key 1024
    
   # generate certificate signing request (same password as above)
   $ openssl req -new -key server.key -out server.csr
    
   # Answer the questions
   Country Name (2 letter code) [AU]: CA
   State or Province Name (full name) [Some-State]: Quebec
   Locality Name (eg, city) []: Montreal
   Organization Name (eg, company) [Internet Widgits Pty Ltd]: Your Company
   Organizational Unit Name (eg, section) []: Development
   Common Name (eg, YOUR name) []: localhost
   Email Address []: [email protected]
   A challenge password []: # leave this empty
   An optional company name []: # leave this empty
    
   # generate the certificate
   $ openssl x509 -req -days 365 -in server.csr -signkey server.key -out server.crt
    
   # remove the password from the server key
   $ cp server.key server.tmp
   $ openssl rsa -in server.tmp -out server.key
    
   # Move the certificate into your MAMP apache configuration folder
   $ cp server.crt /Applications/MAMP/conf/apache
   $ cp server.key /Applications/MAMP/conf/apache
   

3. Open /Applications/MAMP/conf/apache/httpd.conf and uncomment Include /Applications/MAMP/conf/apache/extra/httpd-ssl.conf.

4. Keep your vhost in /Applications/MAMP/conf/apache/extra/httpd-vhosts.conf just the same.

5. In /Applications/MAMP/conf/apache/extra/httpd-ssl.conf, find the following block and edit the fields Server Name and Document Root with the values you already have in your vhost.

   #   General setup for the virtual host
   DocumentRoot "/Applications/MAMP/Library/htdocs"
   ServerName www.example.com:443
   ServerAdmin [email protected]
   ErrorLog "/Applications/MAMP/Library/logs/error_log"
   TransferLog "/Applications/MAMP/Library/logs/access_log"
   and edit in your DocumentRoot and ServerName settings:
   

Happy secure MAMPing!

For anyone interested in making local certificates I like to use mkCert.

It doesn't work for me ... 😣

To use subjectAltName [SAN] in your certificate (needed by Chrome), you can generate you key and certificate like this : https://www.lopau.com/how-to-generate-a-self-signed-ssl-certificate-with-san/
