This document provides instructions for running Apache 2.2 at the command line instead of as a service, stopping the Apache 2.2 service, determining what software is running on port 80, editing the Windows registry, and executing Apache 2.2 from the run command or command prompt. It also includes steps for updating the Java version and restarting the web server after installation.

1. Run apache2.2 at the command-line, instead of as a service.
1. Open the services tab by typing "services.msc" without quotes (start - run) and select
the startup type "Automatic".
2. Click on the recovery tab and from the dropdown select "restart the service" for all the
three options listed i.e., first failure, second failure and subsequent failures. Type "1" in
restart service after. Restart fail count after should be blank.
3. Restart the machine and the above 2 steps should help in restarting apache 2.2
Stopping the apache 2.2 Service.
1. Stop the apache services from services.msc
2. Once it is stopped examine the system logs. Right click on "My Computer" under it an
item "system" and under it an item "event logs". Expand the sub folder "system". You
will messages with timestamps. By double clicking on one item you will see the full
message. Find out when apache 2.2 stops and look around the time and the error
message.
3. Sometimes the apache server stops because something else is on the same port as
apache 2.2. The server port for apache is 80.
4. Type the command "netstat -noa" without quotes in the command line (start - run -
cmd). This will display all the services and the ports on the machine.
-a (displays all connections and listening ports)
-n (displays addresses and port numbers in numberical form)
-o (displays the owing process ID associated with each connection)

2. 5. Stop the services in the task manager once you have know the services that are
running on port 80.
6. Restart the apache services. Restarting apache 2.2 instructions and given above.
Software running on Port 80
Type the command "netstat -o" without quotes in the command line (start - run - cmd).
This will output a list of ports, along with the PID (process ID) that has the port open.
The PID for apache 2.2 is 4116
To determine what executable is running as a process ID, Open windows task manager
and switch to the processes tab. Click on view - select columns. On the screen that
opens, make sure "PID (Process Identifier)" is checked and then click OK. Now click on
the PID heading to sort the entries by PID.
Editing the Windows Registry.
To do this, follow these steps:
1. Edit the windows registry with the "Registry Editor". Click on start - run - regedit. Be
careful not to change any value, because editing the registry is potentially dangerous.
2. This looks like an Explorer window. On the left side, you will see a structure, much
like a directory structure. Find the key "HKEY_LOCAL_MACHINE", expand it, and keep
doing this following the following path: System - CurrentControlSet - Services -
Apache2.2
3. When you click on the Apache key, then in the right panel you will see a series of
key/value things. One of the keys is "ImagePath". Double-click on it, and it will open a
dialog box.

3. 4. Now make sure that you do not change the value. Just copy it with then cancel and
exit the Registry Editor. What you have copied, is the command line command that
starts apache2.2.
5. Open Notepad, and paste the command there, you will need it later.
6. Stop the apache2.2 service if it is running.
7. Open a command window again, and paste the command that you have copied
before. (If the command contains a parameter like "//RS....", remove this parameter).
When you type the return key, this command will be executed, and this will run
apache2.2 in your command window. If you type CTRL-C, apache2.2 will stop. For the
users, it will be exactly the same as if apache2.2 was running as a service. But for you,
you will see on the screen any error messages apache2.2 prints. The difference is that
now apache2.2 runs under the user-id under which you are logged-in on this machine.
So, let it run until it dies, and let's see if you get any error message. Note that you
cannot logoff from the machine, or of course apache2.2 will die.
Executing Apache 2.2.
1. Apache 2.2 can be executed from the run command. Type the command "C:Program
Files (x86)OTRSApachebinhttpd.exe" -k runservice and save the command in a
notepad. This command is located under services - apache 2.2 and copy from path to
executable. The command differs from one machine to another.
2. Click file - save as and in the file name type "apache.bat" and save as type "all files".
3. This command will execute apache 2.2 and start the services.
4. Restart the web server.

4. Updating Java Version
1. Download the new version of java from http://java.com/en/download/index.jsp
2. The latest version as of 23rd May 2012 is Version 7 Update 21.
3. Restart the webserver once you have successfully installed the new java version.
