Installing Apache2 on Linux

Step1: Get tar.gz packages for apache

Download appropriate package

#wget http://apache.mirror.facebook.net/httpd/httpd-2.2.11.tar.gz

Step2: Configure and Install Apache

#tar -xvxf httpd-2.2.11.tar.gz

# mv httpd-2.2.11 /usr/local/

#cd /usr/local/httpd-2.2.11

#./configure

#make

#make install

By default apache will install on /usr/local/apache2

Step3: Configure Apche to start automatically on reboot

# cp /usr/local/apache2/bin/apachectl /etc/init.d/httpd

Add the fllowing lines to /etc/init.d/httpd

#

# Startup script for the Apache Web Server

#

# chkconfig: - 85 15

# description: Apache is a World Wide Web server. It is used to serve

# HTML files and CGI.

# processname: httpd

# pidfile: /usr/local/apache/logs/httpd.pid

# config: /usr/local/apache/conf/httpd.conf

#

Then execute the below commands

# chmod 755 /etc/init.d/httpd

# chkconfig --add httpd

# chkconfig --level 35 httpd on

Note [ If you need a more detailed feedback we can use the below scrip as startup script]

#!/bin/bash

# httpd Startup script for the Apache HTTP Server

# chkconfig: 345 85 15

# description: Apache is a World Wide Web server. It is used to serve

# HTML files and CGI.

# processname: httpd

# config: /usr/local/apache2/conf/httpd.conf

# pidfile: /var/run/apache2.pid

# Source function library.

. /etc/rc.d/init.d/functions

# Start httpd in the C locale by default.

HTTPD_LANG=${HTTPD_LANG-"C"}

# This will prevent initlog from swallowing up a pass-phrase prompt if

# mod_ssl needs a pass-phrase from the user.

INITLOG_ARGS=""

# Path to the apachectl script, server binary, and short-form for messages.

apachectl=/usr/local/apache2/bin/apachectl

httpd=${HTTPD-/usr/local/apache2/bin/httpd}

prog=httpd

pidfile=${PIDFILE-/var/run/apache2.pid}

lockfile=${LOCKFILE-/var/lock/subsys/apache2}

RETVAL=0

start() {

echo -n $"Starting $prog: "

LANG=$HTTPD_LANG daemon $httpd $OPTIONS

RETVAL=$?

echo

[ $RETVAL = 0 ] && touch ${lockfile}

return $RETVAL

}

stop() {

echo -n $"Stopping $prog: "

killproc $httpd

echo

[ $RETVAL = 0 ] && rm -f ${lockfile} ${pidfile}

}

reload() {

echo -n $"Reloading $prog: "

if ! LANG=$HTTPD_LANG $httpd $OPTIONS -t >&/dev/null; then

RETVAL=$?

echo $"not reloading due to configuration syntax error"

failure $"not reloading $httpd due to configuration syntax error"

else

killproc $httpd -HUP

RETVAL=$?

echo $"Usage: $prog {start|stop|restart|condrestart|reload|status|fullstatus|graceful|help|configtest}"

exit 1

esac

exit $RETVAL

Step4: Add path variabled if required

Create a file /etc/profile.d/apache2

# touch /etc/profile.d/apache2

# chmod +x /etc/profile.d/apache2

#vi /etc/profile.d/apache2

#***** Set Env Variables for Apche

APACHE_HOME=/usr/local/apache2

export APACHE_HOME

export PATH=$APACHE_HOME/bin:$PATH

Logout from shell to get this updated
