installing apache httpd server on ubuntu 12.04

Question

I have 5 systems running apache tomcat server, for load balancing i need to install apache httpd server, how should i do this, please provide me some useful links and your opinions on this, thanks

Answer 1

You can just

sudo apt-get install apache2

or

sudo apt-get install apache2.2

If Tomcat is working on 80 port, than you might need more configurations, like default port etc... Hope it helps.

Answer 2

To install apache2 you can do it using the command:

sudo apt-get install apache2

Now if you don't want see this warning every-time you restart apache service

 ... waiting .apache2: Could not reliably determine the server's fully qualified domain name, using 127.0.1.1 for ServerName

Now you want to give a server's fully qualified domain name

gksudo gedit /etc/apache2/httpd.conf 

and name it using the keyword serverName

serverName localhost

I named localhost you can just choose whatever you like.

You don't have any problems with port numbers since tomcat run on port 8080 by default and apache run on port 80 by default.

But anyway if you want to just change the port number of your apache.

To change the port apache is running on you can do it like this:

Open /etc/apache2/ports.conf file, enter:

gksudo /etc/apache2/ports.conf

To make the server accept connections on port 8010 for example instead of 80 search for the word Listen 80 and replace with:

Listen 8010
