For standard OS X installations of MySQL you will find my.cnf located in the /etc/ folder.

Steps to update this variable:

Load Terminal.
Type cd /etc/.
sudo vi my.cnf.
This file should already exist (if not please use sudo find / -name 'my.cnf' 2>1 - this will hide the errors and only report the successfile file location).
Using vi(m) find the line innodb_buffer_pool_size, press i to start making changes.
When finished, press esc, shift+colon and type wq.
Profit (done).

In the earlier versions of MySQL    lt  5 7 5   the only way to set       innodb buffer pool size    variable was by writing it to my cnf  for linux  and my ini  for windows  under  mysqld  section     mysqld   innodb buffer pool size   2147483648   You need to restart your mysql server to have it s effect in action   UPDATE       As of MySQL 5 7 5  the innodb buffer pool size configuration option   can be set dynamically using a SET statement  allowing you to resize   the buffer pool without restarting the server  For example   mysql gt  SET GLOBAL innodb buffer pool size 402653184     Reference   https   dev mysql com doc refman 5 7 en innodb-buffer-pool-resize html

As stated   innodb buffer pool size 50M   Following the convention on the other predefined variables  make sure there is no space either side of the equals sign   Then run  sudo service mysqld stop sudo service mysqld start   Note  Sometimes  e g  on Ubuntu  the MySQL daemon is named mysql as opposed to mysqld  I find that running  etc init d mysqld restart doesn t always work and you may get an error like  Stopping mysqld                                             FAILED  Starting mysqld                                               OK      To see if the variable has been set  run show variables and see if the value has been updated
