See whether your compiled Apache is prefork or worker MPM

For some of my web servers I setup and configure, for scaling I use the httpd.conf settings for these. Sometimes I forget which servers are prefork and which are worker MPM, so I use this to remind myself.
Sample Output
Compiled in modules:
  core.c
  prefork.c
  http_core.c
  mod_so.c

  • Nginx (and other webservers like Apache) can be awkward to trace. They run as root, then switch to another user once they're ready to serve web pages. They also have a "master" process and multiple worker processes. The given command finds the process IDs of all Nginx processes, joins them together with a comma, then traces all of them at once with "sudo strace." System trace output can be overwhelming, so we only capture "networking" output. TIP: to kill this complex strace, do "sudo killall strace". Compare with a similar command: http://www.commandlinefu.com/commands/view/11918/easily-strace-all-your-apache-processes Show Sample Output

    sudo strace -e trace=network -p `pidof nginx | sed -e 's/ /,/g'`

  • This version also attaches to new processes forked by the parent apache process. That way you can trace all current and *future* apache processes.

    ps auxw | grep sbin/apache | awk '{print"-p " $2}' | xargs strace -f

  • Will open strace on all apache process, on systems using sbin/apache (debian) or sbin/httpd (redhat), and will follow threads newly created.


    2
    ps auxw | grep -E 'sbin/(apache|httpd)' | awk '{print"-p " $2}' | xargs strace -F

  • Simply add this to whatever apache startup script you have, or if you are on a MAC, create a new automator application. This will show a pretty growl notification whenever theres a new Apache error log entry. Useful for local development
