It means that apache want to use SysV IPC. (semaphore get function)
Inter process communication
These software objects (semaphores,shared memory and signals) enables the processes to exchange information.
Apache processes wants to exchange information via semaphores but could not,
You current Linux kernel dont have SystemV IPC support.
You should build a new Linux kernel with a SystemV IPC support.
You will have to rebuild the kernel with that support enabled (it's under the "General Setup" submenu)

go to the linux web site and down load ubantu to a usb stick
then burn a disc from that usb stick
use the disc to install the os on the computer
ubuntu is the same system as win 7 but with different names for the files and folders so it is easy to pick up and use
if you still have problems there are linux forums with plenty of help as to problems associated with using linux products
I found that it will not install directly from the usb stick and that has been mentioned in the forums but is readily capable from the disc for some reason or other
there are many linux operating system such as apache and the like but ubuntu is by far the easiest and most common
Libra is a very good office suite operating system from linux
Hi Follow the below procedures. How to install and start the Apache or httpd service under Linux
Q. How do I install and start the Apache or httpd web server under Fedora core or Cent OS?
A. Apache HTTP Server is a free software/open source web server for Unix-like systems and other oses.
Apache features configurable error messages, DBMS-based authentication databases, and content negotiation. It is also supported by several graphical user interfaces (GUIs) which permit easier, more intuitive configuration of the server.
Use rpm command to install Apache under Linux. You can also use up2date or yum command to install the same. Task: Install Apache/httpd under Fedroa Core/Cent OS Linux
Type the following command if you are using Fedora or Cent OS Linux:
# yum install httpd Now, start the Apache/httpd # chkconfig httpd on # /etc/init.d/httpd start Task: Install Apache/httpd under Red Hat Enterprise Linux
Type the following command # up2date httpd Start the Apache/httpd # chkconfig httpd on # /etc/init.d/httpd start Task: Debian Linux httpd/Apache installation
Use apt-get command: # apt-get install apache2 # /etc/init.d/apache2 start Task: Verify that port 80 is open
# netstat -tulpn | grep :80
You can also install httpd from CDROM with rpm command: # rpm -ivh httpd* Configuration
Your server is started but you need to configure and use Apache as per your requirement. /etc/httpd/conf/httpd.conf (RHEL/Cent OS/Fedora Core Linux) or /etc/apache2/httpd.conf (Debian / Ubuntu Linux) configuration file. Use text editor such as vi to edit file. This file is very well documented or read official Apache configuration documentation for more information.
The Web server is meant for keeping Websites. There are three ways a Website can be stored. They are:
1 - Default directory hosting
2 - Virtual directory hosting
3 - Virtual domain hosting 4 - Security Etc....
Hello,You can try this http://www.goresellers.com/ site's more DNS ,here you can make your self as a reseller and get your expected DNS are very very cheap rate, also you got an internet business opportunity ,visit this site for more details.
First, is it really necessary to restart the server? can you just restart the service from Administrative tools -> Services? (Not a solution but might help a little whilst you're looking for one :)
Is there a reason why you are running Apache on 8080? Is IIS on 80? If so, I wonder if it may be stealing 8080 from Apache when the Apache worker restarts after its maximum allowed run time. As to why IIS should be doing that, I have no idea :) Also, is Apache configured for SSL? If it is, then it will be trying to use port 443 as well, as may IIS - & thus the above error message may be due to both trying to use 443 rather than 80 or 8080.
If you really can't get this working then running Windows & Linux (a LAMP installation) under VMWare or something similar may be an option. It's not as drastic as it sounds - I've done this on a laptop PC & it works!
As I had mentioned earlier to another gentleman, who had a similar issue; those SOHO routers and modem/routers have issues with their advanced functionalities which includes port forwarding. The first thing you must do is
- Make sure 'block anonymous internet requests', is disabled in the router's settings
- Go to the following website http://www.t1shopper.com/tools/port-scanner/
- Try to see if there is a service running on port 80
If the port is open (which I believe would be a least possibility), there is something else we are missing here.
Get back to me with further observations
