The following scripts can help in determining good values for Apache and MySQL configurations based on the amount of memory available:
The following will give a list of Apache Modules loaded:
apachectl -t -D DUMP_MODULES
The following will give the memory usage of Apache:
#!/bin/sh
# apache_mem.sh
# Calculate the Apache memory usage
ps -ef | grep httpd | grep ^apache | awk ‘{ print $2 }’ |
xargs pmap -x | grep ‘total kB’ | awk ‘{ print $3 }’ |
awk ‘{ sum += $1 } END { print sum }’
The following will give
<?php
phpinfo();
?>
From my investigations it looks like my Apache processes had been using a lot of memory due to the mod-security rules I had obtained from ASL – now to customise them.
