Cannot start MySQL server with AppleScript – Snow Leopard

I've sucessfully installed MySQL server (5.5.11) on my MAC Snow Leopard. I can start the server using PreferencePane, using command line sudo /usr/local/mysql/bin/mysqld_safe but cannot use the same command within AppleScript.

This is the output from running sudo /user/local/mysql/bin/mysql_safe:

ngocminh@MBP[304]:~$ sudo /usr/local/mysql/bin/mysqld_safe 
Password:
110428 09:52:03 mysqld_safe Logging to '/usr/local/mysql/data/MBP.local.err'.
110428 09:52:03 mysqld_safe Starting mysqld daemon with databases from /usr/local/mysql/data

Apache2 server can be started using the command sudo apachetl start, then it could be implemented using an AppleScript script like this:

do shell script "apachectl start" password "mypassword" user name "ngocminh" with administrator privileges

However, I can't simply do the same for starting mysql server

do shell script "/usr/local/mysql/bin/mysqld_safe" password "mypassword" user name "ngocminh" with administrator privileges

The apple script result says:

"110428 11:03:06 mysqld_safe Logging to '/usr/local/mysql/data/MBP.local.err'.
110428 11:03:06 mysqld_safe Starting mysqld daemon with databases from /usr/local/mysql/data
110428 11:03:06 mysqld_safe mysqld from pid file /usr/local/mysql/data/MBP.local.pid ended"

Then MySQL server cannot be started!

Would anybody tell what's wrong with my script or I've missed something. Any suggestion will be highly appreciated. Thank you!

— EDIT 1 —

Try to run this script instead

do shell script "apachectl start" password "mypassword" with administrator privileges do shell script "/usr/local/mysql/bin/mysqld_safe > /dev/null 2>&1 &" password "mypassword" with administrator privileges

No error reported by AppleScript but MySQL server is still not loaded according to ps command

— EDIT 2– PROBLEM SOLVED!

I found the way around it. Just creat an AppleScript with sudo inside for mysql server startup

do shell script "apachectl start" password "mypassword" with administrator privileges
do shell script "sudo /usr/local/mysql/bin/mysqld_safe > /dev/null 2>&1 &" password "mypassword" with administrator privileges
