How to change value for innodb_buffer_pool_size in MySQL on Mac OS?

Question

I am trying to increase the size of the innodb_buffer_pool_size in MySQL 5.1 as I keep running into the following error indicating I have run out of space for the table lock

Answer 1

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

Steps to update this variable:

1. Load Terminal.
2. Type cd /etc/.
3. sudo vi my.cnf.
4. 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).
5. Using vi(m) find the line innodb_buffer_pool_size, press i to start making changes.
6. When finished, press esc, shift+colon and type wq.
7. Profit (done).
