Solution for the MAMP "#2006 - MySQL server has gone away" error

 / Published in: Bash

Credit goes to shyul and the original forum post here: original_post You need to modify the following file " ...\MAMP\bin\" with the code bellow

  1. # /bin/sh
  2. /Applications/MAMP/Library/bin/mysqld_safe --port=3306 --max_allowed_packet=268435456 --socket=/Applications/MAMP/tmp/mysql/mysql.sock --lower_case_table_names=0 --pid-file=/Applications/MAMP/tmp/mysql/ --log-error=/Applications/MAMP/logs/mysql_error_log &

If you are a person who tried all the tutorials from the internet and still not solve your problem? - This was the solution for me:

(This code the SET GLOBAL maxallowedpacket = 64 * 1024 * 1024, and more changes in the code were the solution)


MAKE: In your MAMP go to File> Edit Template> MySQL my.cnf and Select. MAMP will open its own editor. By doing so, delete the Scrypt and paste this:

Example MySQL config file for medium systems.


This is for a system with little memory (32M - 64M) where MySQL plays

an important part, or systems up to 128M where MySQL is used together with

other programs (such as a web server)


You can copy this file to

/etc/my.cnf to set global options,

mysql-data-dir/my.cnf to set server-specific options (in this

installation this directory is /Applications/MAMP/db/mysql) or

~/.my.cnf to set user-specific options.


In this file, you can use all long options that a program supports.

If you want to know which options a program supports, run the program

with the "--help" option.

The following options will be passed to all MySQL clients


password = your_password

port = 9999

socket = /Applications/MAMP/tmp/mysql/mysql.sock

Here follows entries for some specific programs

The MySQL server


port = 9999

socket = /Applications/MAMP/tmp/mysql/mysql.sock keybuffer = 320M maxallowedpacket = 320M tablecache = 64 sortbuffersize = 512K netbufferlength = 8K readbuffersize = 256K readrndbuffersize = 512K myisamsortbuffersize = 8M bind-address =

Don't listen on a TCP/IP port at all. This can be a security enhancement,

if all processes that need to connect to mysqld run on the same host.

All interaction with mysqld must be made via Unix sockets or named pipes.

Note that using this option without enabling named pipes on Windows

(via the "enable-named-pipe" option) will render mysqld useless!


Replication Master Server (default)

binary logging is required for replication


required unique id between 1 and 2^32 - 1

defaults to 1 if master-host is not set

but will not function as a master if omitted

server-id = 1

Replication Slave (comment out master section to use this)


To configure this host as a replication slave, you can choose between

two methods :


1) Use the CHANGE MASTER TO command (fully described in our manual) -

the syntax is:





where you replace , , by quoted strings and

by the master's port number (3306 by default).









2) Set the variables below. However, in case you choose this method, then

start replication for the first time (even unsuccessfully, for example

if you mistyped the password in master-password and the slave fails to

connect), the slave will create a file, and any later

change in this file to the variables' values below will be ignored and

overridden by the content of the file, unless you shutdown

the slave server, delete and restart the slaver server.

For that reason, you may want to leave the lines below untouched

(commented) and instead use CHANGE MASTER TO (see above)


required unique id between 2 and 2^32 - 1

(and different from the master)

defaults to 2 if master-host is set

but will not function as a slave if omitted

server-id = 2


The replication master for this slave - required

master-host =


The username the slave will use for authentication when connecting

to the master - required

master-user =


The password the slave will authenticate with when connecting to

the master - required

master-password =


The port the master is listening on.

optional - defaults to 3306

master-port =


binary logging - not required for slaves, but recommended


Point the following paths to different dedicated disks

tmpdir = /tmp/

log-update = /path-to-dedicated-directory/hostname

Uncomment the following if you are using BDB tables

bdbcachesize = 4M

bdbmaxlock = 10000

Uncomment the following if you are using InnoDB tables

innodbdatahome_dir = /Applications/MAMP/db/mysql/

innodbdatafile_path = ibdata1:10M:autoextend

innodbloggrouphomedir = /Applications/MAMP/db/mysql/

innodblogarch_dir = /Applications/MAMP/db/mysql/

You can set ..bufferpool_size up to 50 - 80 %

of RAM but beware of setting memory usage too high

innodbbufferpool_size = 16M

innodbadditionalmempoolsize = 2M

Set ..logfile_size to 25 % of buffer pool size

innodblogfile_size = 5M

innodblogbuffer_size = 8M

innodbflushlogattrx_commit = 1

innodblockwait_timeout = 50

[mysqldump] quick maxallowedpacket = 320M

[mysql] no-auto-rehash

Remove the next comment character if you are not familiar with SQL


[isamchk] keybuffer = 20M sortbuffersize = 20M readbuffer = 2M write_buffer = 2M

[myisamchk] keybuffer = 20M sortbuffersize = 20M readbuffer = 2M write_buffer = 2M

[mysqlhotcopy] interactive-timeout

DONT REMOVE: MAMP PRO my.cnf template compatibility version: 3

set global maxallowedpacket=6410241024;

Thanks are welcome! ^^
