Suggestion: max_allowed_packet instructions in installation documentation

[alwashmi]

Here in the documentation, the installation instructions point people to modify max_allowed_packet global variable by running SET GLOBAL max_allowed_packet=41943040;. However, this setting doesn't persist.
I suggest modifying the file /etc/mysql/my.cnf by adding the following two lines:

[mysqld]
max_allowed_packet=40M

Then, restarting the mysql service as follows

service mysql restart

This way the setting persists.
