Shell Script to Check apache installed or not.

OS :- Linux

Using Shell Script, how can i check whether apache is installed in my system, if yes how could i retrive the version no., httpd.conf file path, apachectl file path and httpd file path.

httpd should be on the filepath, so "httpd --version" will return the version number, and the exit status of that command (echo $?) should be 0 if it is installed, > 0 otherwise.

hi acid_kewpie,
Thanks for your reply,

using this statment /usr/sbin/httpd -v i can find the version no. of the apache. but first i need to location the httpd file. how can i get this one.

???? you're already giving it an absolute file path! you know where it is!

i know this httpd path in my system and to get the information manually,

but i need to design a script which will be excuted in other systems and locate apache installed path and get the listed information automatically.

any help please

Hi, apt

How about this shell script?
i think that this script meets your problem.

Code:

#!/bin/sh

# find files
conf=`find / -name httpd.conf`
ctl=`find / -name apachectl`
httpd=`find / -name httpd | grep bin`

### output
# httpd.conf
echo -n "httpd.conf: "
if [ $conf = "" ]
then
        echo "NOT EXIST!!"
else
        echo $conf
fi

# apachectl
echo -n "apachectl: "
if [ $ctl = "" ]
then
        echo "NOT EXIST!!"
else
        echo $ctl
fi

# httpd
echo -n "httpd: "
if [ $httpd = "" ]
then
        echo "NOT EXIST!!"
else
        echo $httpd
        echo ""
        $httpd -v
fi

I would rather use a list of usual path for httpd and if the user installed it in an unusual directory, the
script may pause after the search fails and ask the user where httpd is eg :

Code:

#!/bin/bash
KNOWN_PATH="/usr/sbin /sbin /opt/apache2/bin /usr/local/sbin"
HTTPD_DIR=

for path in $KNOWN_PATH; do
    echo "trying $path/httpd..."
    if `ls $path/httpd > /dev/null 2>&1`; then
        HTTPD_DIR=$path
        break
    fi
done

if [ -z $HTTPD_DIR ]; then
    echo "httpd path not found, please enter the path to directory where httpd is"
    echo -n "httpd path : "
    read HTTPD_DIR
fi
HTTPD="$HTTPD_DIR/httpd"

if [ ! -x $HTTPD ]; then
    echo "httpd could not be found, exiting..."
    exit 1
fi
$HTTPD -V
