MAMP Pro

Introduction

MAMP Pro is a very handy tool for having a Webserver with PHP and MySql on your Mac.
To obtain MAMP for Installation and Update you need to:

Download MAMP PRO from www.mamp.info.

Installation

Installing is simple and only given here for reference.

Follow the guidelines given on that Website documentation.mamp.info.

Update

To update is different cook. It all depends how you have configured your websites in MAMP and MAMP-Pro. The best way to create websites is outside the MAMP (PRO) environment. That prevents a lot of trouble (shit).

Manage ownership

MAMP has the user _www as default user to run the MAMP-server. When you try to run a Terminal application that uses files from the Server owned directory you need to do a sudo:

$ sudo ./<My-Appl-Cli> --about 
Password:

Give your OSX password and that will do the trick. Another way is to do is to use su, but that's even more annoying.

The best way is to change the group of the directory in the admin user (I think every Apple owner is also the admin of his device).

$ ls -Al /Applications/MAMP/www/Log 
-rw-rw-r--@ 1 _www  _www        457 Oct  1 13:32 .htaccess
-rw-rw-r--  1 _www  _www     103138 Jun 26  2016 Log4Anno.log
-rwxrwxr-x  1 _www  _www   11558605 Nov 15 19:04 Log4DbTrace.log
-rw-rw-r--  1 _www  _www    4249529 Nov 21 16:25 Log4Energy.log
...
-rw-rw-r--  1 _www  admin     28624 Nov 22 09:03 Log4Whois.log

# Change the ownership of the group
$ cd /Applications/MAMP/www/Log
$ sudo chown :admin Log4DbTrace.log
Password:
$ ls -Al Log4DbTrace.log
-rwxrwxr-x  1 _www  admin    11M Nov 15 19:04 Log4DbTrace.log

Mail

If you try to send a mail with MAMP Pro you will notice that this is not working out-of-the-box. MAMP Pro uses postfix as you can find on the last tab of the MAMP Pro app.

Just fill in 'gmail.com' at the Domain of outgoing mail and restart the server.
Now open the mail log file which is located in the /var/log directory and you will see:

May 28 16:09:39 Harms-MBP-3.fritz.box postfix/master[78220]: fatal: bind fe80::1 port 25: Can't assign requested address
May 28 16:09:49 Harms-MBP-3.fritz.box postfix/master[78221]: fatal: bind fe80::1 port 25: Can't assign requested address

The reason of these errors is located in the wrong binding to the ipv6 instead of the ipv4.

To change this:

Edit the file main.cf located in the /etc/postfix/main.cf in terminal.
Type
```
$ sudo nano /etc/postfix/main.cf
```
Add the line
```
inet_protocols = ipv4
```
Save the file in nano.
Stop postfix:
```
 sudo launchctl stop org.postfix.master
```

Start postfix:

 sudo launchctl start org.postfix.master

Now look in the mail.log
```
tail -f -n 65 /var/log/mail.log
```
Resulting in

May 28 16:28:29 Harms-MBP-3.fritz.box postfix/master[78439]: fatal: bind fe80::1 port 25: Can't assign requested address
May 28 16:28:40 Harms-MBP-3.fritz.box postfix/master[78440]: daemon started -- version 2.11.0, configuration /etc/postfix
May 28 16:29:26 Harms-MBP-3.fritz.box postfix/master[78440]: terminating on signal 15
May 28 16:29:26 Harms-MBP-3.fritz.box postfix/master[78443]: daemon started -- version 2.11.0, configuration /etc/postfix

Fixed, the deamon has been started (see line2).

Mysql

When you receive the following warning on mysql on OSX:

 PHP Warning:  mysqli_connect(): (HY000/2002): No such file or directory in /Data/.../Database.php on line 258
[26-Oct-2018 08:58:13 Europe/Berlin] PHP Stack trace:
[26-Oct-2018 08:58:13 Europe/Berlin] PHP   1. {main}() /Applications/MAMP/www/.../DbTrace-be.php:0
[26-Oct-2018 08:58:13 Europe/Berlin] ...
[26-Oct-2018 08:58:13 Europe/Berlin] PHP   8. mysqli_connect(*uninitialized*, *uninitialized*, *uninitialized*) /Data/.../Database.php:258

Solution

For some reason mysql on OS X gets the locations of the required socket file a bit wrong, but thankfully the solution is as simple as setting up a symbolic link.
You may have a socket (appearing as a zero length file) as /tmp/mysql.sock or /var/mysql/mysql.sock, but one or more apps is looking in the other location for it.
Find out with this command:

$ ls -l /tmp/mysql.sock /var/mysql/mysql.sock

Stack-Overflow, War

Rather than move the socket, edit config files, and have to remember to keep edited files local and away from servers where the paths are correct, simply create a symbolic link so your Mac finds the required socket, even when it's looking in the wrong place! ^[1]
'Comment: Exactly what I had with earlier MAMP installations, but since you are doing this once, you don't remember it. If you have /tmp/mysql.sock but no /var/mysql/mysql.sock then..

$ cd /var 
$ sudo mkdir mysql
$ sudo chmod 755 mysql
$ cd mysql
$ sudo ln -s /tmp/mysql.sock mysql.sock

If you have /var/mysql/mysql.sock but no /tmp/mysql.sock then...

$ cd /tmp
$ ln -s /var/mysql/mysql.sock mysql.sock

You will need permissions to create the directory and link, so just prefix the commands above with sudo if necessary ^[1].
Comment: If you have already symbolic links use the resulting file iso creating a symbolic link to a symbolic link.

php xDebug

The following problem can occur while using xDebug ^[2]

Xdebug: [Step Debug] Could not connect to debugging client. Tried: localhost:9003 (through xdebug.client_host/xdebug.client_port) :-(

Look at the configuration of php in MAMP Pro ^[3]

[xdebug]
MAMP_Xdebug_MAMPzend_extension="/Applications/MAMP/bin/php/php8.2.0/lib/php/extensions/no-debug-non-zts-20220829/xdebug.so"
xdebug.mode=debug
xdebug.start_with_request=yes
xdebug.client_port=9003
xdebug.client_host=localhost
xdebug.output_dir="/Applications/MAMP/tmp"

If you set the log level to zero, this annoying message is not shown:

; Added by Harm Frielink HaFr
; Unfortunately, the only way to disable this error is to disable 
; generally ALL errors & warnings in xdebug.ini:
xdebug.log_level = 0

Level	Name	Example
0	Criticals	Errors in the configuration
1	Errors	Connection errors
3	Warnings	Connection warnings
5	Communication	Protocol messages
7	Information	Information while connecting
10	Debug	Breakpoint resolving information

StartTLS

The mail.log is located in the /var/log.

After fixing the above issue the next problem is that the name of the host is taken as default name for the mail-send-account.
In the example below look for:
- status=bounced
- Must issue a STARTTLS command first.

The problem with the above is that the from field is not field correctly. The PHP-mail command has the following signature and parameters:

boolean mail ( string $to , string $subject , string $message [, string $additional_headers [, string $additional_parameters ]] )

Parameters:

$to Receiver, or receivers of the mail.
The formatting of this string must comply with » RFC 2822. Some examples are:
- user@example.com
- user@example.com, anotheruser@example.com
- User <user@example.com>
- User <user@example.com>, Another User <anotheruser@example.com>
$subject Subject of the email to be sent. (Subject must satisfy » RFC 2047).
$message Message to be sent.
Each line should be separated with a CRLF (\r\n). Lines should not be larger than 70 characters.
$additional_headers (optional) String to be inserted at the end of the email header.
- This is typically used to add extra headers (From, Cc, and Bcc). Multiple extra headers should be separated with a CRLF (\r\n). If outside data are used to compose this header, the data should be sanitized so that no unwanted headers could be injected.
  - When sending mail, the mail must contain a From header. This can be set with the additional_headers parameter, or a default can be set in php.ini.
  - Failing to do this will result in an error message similar to Warning: mail(): "sendmail_from" not set in php.ini or custom "From:" header missing. The From header sets also Return-Path under Windows.

Note:
If messages are not received, try using a LF (\n) only. Some Unix mail transfer agents (most notably » qmail) replace LF by CRLF automatically (which leads to doubling CR if CRLF is used). This should be a last resort, as it does not comply with » RFC 2822. additional_parameters (optional)
The $additional_parameters parameter can be used to pass additional flags as command line options to the program configured to be used when sending mail, as defined by the sendmail_path configuration setting. For example, this can be used to set the envelope sender address (-fxxx@yyy.zz).

The mail from has to be set twice to be absolute sure it will work correctly:

In the $additional_header. Please note the specific formatting of this field.
In the $additional_parameters. Please note the format: -ffrom@xxx.nl without a space between -f and the email address (i.e. -fharm@harmfrielink.nl).

Which TCP Ports are open

Check for open TCP ports using Network Utility on Mac TCP/IP communications between your computer and other computers on the internet pass through numbered logical ports on each computer.
Knowing which ports are open on your computer can help you assess the security of your system or troubleshoot connection problems.
On your Mac, open the Network Utility app, located in the /System/Library/CoreServices/Applications folder.

Click Port Scan, enter your IP address, then click the Scan button.
For SMTP you need to have open post 25 and 465. But the latest port has been replaced by port 587
To find your IP address, choose Apple menu → System Preferences, click Network, then select a network service, such as Ethernet or Wi-Fi.

Open TCP Port

That is a bit tricky to do. The firewall may prohibit this action. Normally you do not need to open a port on your Mac!

Open Terminal,
Run the following command: nc -l localhost portnumber (replace portnumber with the actual number of the port you need to open).
It looks like it doesn’t do a thing because netcat is waiting for a connection on that por

# Opens the closed smpt port number 587.
$ nc -l localhost 587

BUT for SMTP do not use this port! Use port 587 instead!

Example MAMP Configuration

MAMP Postfix for One

Since the gmail configuration gives bounced error due to authorization conflicts. I have used my own service provider One.com.

Set domain of outgoing emails

Use the basic name of the service provider (i.e. one.com) or for gmail (i.e. gmail.com).

Use a Smart host for Routing

Use the full name of the smtp service (i.e. send.one.com). In case of gmail (i.e. smtp.gmail.com).

Authentication

For one (i.e. Unencrypted).

User Name

The user name for the service provide (i.e. harm@harmfrielink.nl).

Password

The password. (i.e. ???).
