apachebuddy.pl's Introduction

Apachebuddy.pl supercedes my own Redhat only bash script 'apachetuner.sh' so am hosting it.
However there is no active development on this perl script, because there are beter ways to achieve the same. 

Please check out Satori: http://satori.readthedocs.org/en/latest/ and 'ohai-solo' where most of the apachebuddy functionality has been implemented as Apache-plugins. See https://github.com/rackerlabs/ohai-plugins and particularly the Apache2 plugins: https://github.com/rackerlabs/ohai-plugins/blob/master/plugins/apache2.rb )

GET:
Grab this from http://apachebuddy.pl  (thanks to Will Parsons for that domain name)

BEWARE:
Do NOT run code you dont control as root on a server you care about. Who says something nefarious has not crept into this code? Just saying. Stay safe and review EVERYTHING.

If you use this daily, consider rolling .rpm and .debs for it.

    To suppress this warning assign a defined value to your variables.

    To help you figure out what was undefined, perl will try to tell you the
    name of the variable (if any) that was undefined. In some cases it cannot
    do this, so it also tells you what operation you used the undefined value
    in.  Note, however, that perl optimizes your program and the operation
    displayed in the warning may not necessarily appear literally in your
    program.  For example, "that $foo" is usually optimized into "that "

Question: get_apache_model

In get_apache_model()

my $model = $process_name -l | egrep "worker.c|prefork.c";

doesn't work in CENTOS 7.0 when I switch over from prefork to mpm

I had to hack the code to use $process_name -V | egrep "worker|prefork" to determine mpm/worker.

I wish this could be ported for NGINX web engine.

Host in one place

Hi Gus,

Since I added a few changes, I just wanted to make sure that the "current "version is always served.

I registered 'apachebuddy.pl' domain which redirects to the raw master on GitHub.

I think it might be an idea to drop the RPMs and the Cloud Files link, unless you want to keep them up to date?

Will.

event model trips up the script

This script uses the value for event mpm if it exists in the config, no matter which model actually is in use.

Still having this issue. I found that it actually works on my other Amazon Linux instance though. It's strange.

"An undefined value was used as if it were already defined."

Just trying this out for the first time on an Amazon Linux (more or less Centos 6) box. Got this output on the first shot:

Using the event mpm

Just tried this out and it doesn't report that I am using the event mpm. Furthermore, it is showing a maxclients value of 256, however, because I am using the event-mpm it should be showing the value of maxrequestworkers which is 500. That maxclients value is automatically written into the httpd.conf file and I am specifying my own values below it including the maxrequestworkers value as it should be for apache 2.4.

The process running on port 80 is not Apache

Any idea what may be causing this?
