This has been very helpful for me to get up to speed. and getting both of the mysql instances running in parallel Andi, I've encountered exactly the same problem, try this - i think this will resolve your problem: /usr/local/mysqlg/bin/mysqld_safe --defaults-file=/usr/local/mysqlg/my.cnf & By doing so you explicitly tell mysql to use your new my.cnf. Also, i've made a change in mysqld_safe script as well to use my own user - u might want to try it as well. In my version it's on line 21 user='mysqlg' Guys thank you for starting this thread.

Andi,
I’ve encountered exactly the same problem, try this – i think this will resolve your problem:
/usr/local/mysqlg/bin/mysqld_safe –defaults-file=/usr/local/mysqlg/my.cnf &

By doing so you explicitly tell mysql to use your new my.cnf.

Also, i’ve made a change in mysqld_safe script as well to use my own user – u might want to try it as well. In my version it’s on line 21 user=’mysqlg’

Let me know if this worked out

Please cd to the mysql installation directory and restart this script from there as follows: ./bin/mysqld_safe& See http://dev.mysql.com/doc/mysql/en/mysqld-safe.html for more information So you can see that I have set up an own group and user for this version and I have put the edited my.cnf to the local mysql dir. Thank you for the tip, I will try the sandbox when I have understood more. I have been on this site already and just tried to start the alternative server this way:

bin/mysqld_safe –user=mysqlg –datadir=/usr/local/mysqlg/data &
[1] 8472
root@xx:/usr/local/mysqlg# 090612 12:55:15 mysqld_safe Logging to ‘/usr/local/mysqlg/data/mesolt11.err’.
090612 12:55:15 mysqld_safe The file /usr/local/mysql/bin/mysqld
does not exist or is not executable. Please cd to the mysql installation
directory and restart this script from there as follows:
./bin/mysqld_safe&
See http://dev.mysql.com/doc/mysql/en/mysqld-safe.html for more information

So you can see that I have set up an own group and user for this version and I have put the edited my.cnf to the local mysql dir.

Thank you for the tip, I will try the sandbox when I have understood more.

But, I must say that I’ve been using MySQL sandbox quite a lot lately, and, if it suits your needs – it’s really great! You should give it a try.

It seems that the alternative version is connecting through the wrong socket and so tries to read /etc/mysql/my.cnf instead of the alternative my.cnf How does MySQL know where my.cnf is located.
