Shell script for Apache

TuxLives · 01-27-2007, 03:35 PM

I want a script that will

1. Check if apache is running
2. if so, echo "its running"
3. if not, start Apache
4. Check if apache is running (or has started or something) and echo "Apache started"

Any pointers?

PS

I can do this /usr/sbin/apachectl graceful just to make it happend, but I want to play with some shell scripting.

well the service script in /etc/init.d/ will do this already. check it out.

Read the following manual pages:
pidof, pgrep, ps, grep, httpd, bash (for some things like shell expansion). You would better copy-and-paste apache launch command from init script (I do not think it is a good idea to master all switches of Apache web server without need), but all the rest is relatively easy. Find where pid file lies, read it, check that such PID exists, check it is owned by Apache.

I'm less concerned about the specifics because I am not doing any system administration. This is just for my dev machine at home.

Trying to learn a few things.

Quick and dirty way would be to use the ps command and grep for httpd, which is what the process is always listed as or run as.

From that point, if it's present, do nothing, if it's not, start it. I'll let you come up with the script so you actually learn something if you really want to develop your own bash script or Perl even.. whatever floats your boat..

I was wrong.. httpd will start normally without any switches.
