Question about Server Debug Info

+1 vote
28 views

On two different occasions and on two different servers I have found server debug information written out to the mysqld.log file.

Now I know that by issuing the kill -1 mysql-pid will write that information to the mysqld.log file, and by using mysqladmin debug will also write debug information to the mysqld.log file.

I am wondering what other methods would write the debug info to the mysqld.log file. On the two servers in question my fellow DBA's nor myself did nothing that would have written debug info.

Are there any internal settings or processes that would write debug information to the mysqld.log file? Could a client tool do something like this? We have reviewed the app privileges and the they have no ability to write debug info.

My index.php file is compiled correctly when I use one of my PHP executables outside Apache, but fails when I ask Apache to serve it (and fails leaving a blank error log unfortunately). So I'm trying to understand how and where the two PHP compilations start behaving differently.

With my outside-Apache PHP executable, I only need to edit the php.ini file to use xdebug and get first-class debugging. I have no idea how to do the parallel analysis with Apache however. AFAIK, there is no PHP executable inside Apache, just a shared library likeat /libexec/apache2/libphp5.so, and I do not know how to debug that. Does Apache have a php.ini file also? My current system is Mac El Capitan by the way.
