hi folks i am new to apache2 server i have been trying to start the server using the default httpd.conf file provided in the source code but when i give the following command sudo /usr/local/apache/bin/apachectl start i receive the above error and the server shuts down. any kind of help will be highly appreciated.

why /usr/local/apache/bin/apachectl ?
"/etc/init.d/apache2 start" is better
"Address already in use" - no comments. lsof -i -n|grep http

thanks man that worked i understood the mistake

What you were doing was probably starting another httpd process while there was already one running and used port 80.
You might want to try with apachectl restart

You should explicitly select one to install.

E: Package 'httpd' has no installation candidate
root@# service apache2 start

Please check which are the process running in the apache port (80 or which custom port you are using) using netstat -nlp | grep 80, check the process which is running in the same port. Kill that process (using kill -9 PID) and restart the apache.

It may occasionally be required to kill -15 apache processes that refuse to die.

I've also had some strange situations where shared memory segments and semaphores have been left and had to be removed.

So is this solved?
