I followed your instructions on how to install Apache and they worked fine. The server started without problem. Then I installed PHP and restarted Apache. It gave the “Requested Operation Failed” error. Any ideas? Thanks for the work you did.
A ‘Requested Operation Failed’ error from Apache generally means something is wrong with the configuration file – httpd.conf. It may also result because another program is using port 80.
Firstly, make sure that you’ve edited the Apache httpd.conf file properly. Any stray characters will completely ruin the server configuration and prevent it from starting, resulting in a Requested Operation Filed error. Check and double-check the modifications you’ve made to the configuration file. I also suggest rebooting your computer.
Remember you can test the Apache configuration through “Programs” -> “Apache HTTP Server 2.2” -> “Configure Apache Server” -> “Test Configuration“. If things are fine, a terminal window should quickly appear and then disappear.
The “Requested Operation Failed ” error may also be because of another program using port 80. A case in point is the popular video conferencing program, Skype. To get around this problem, change the port that Skype uses – “Tools” -> “Options” -> “Advanced” -> “Connection” and uncheck “Use port 80 and 443 as alternatives for incoming connections“.
Firewalls and anti-virus programs (Norton) can also be prevent Apache web server from starting up properly.
Conclusion: It seems you have made a mistake while editing the Apache httpd.conf file because of which the web server throws a ‘Requested Operation Failed’ error; remember, it worked fine the first time and failed after PHP was installed.
Starting 2011, Google agreed to pay Mozilla Corporation a tad less than half a billion dollars over a period of 3 years if they kept Google as the default search engine on their Firefox web browser. This was a very smart move from the company. Because in 2008, Google had launched Chrome, their own web browser, which had the world's most popular search engine as the default. Additionally, by the end of 2011, Chrome's usage surpassed that of Firefox, and by early 2012, it had exceeded that of Internet Explorer. It was now the world's most popular web browser. So, even though some might think that Google spent a gargantuan sum of money needlessly, I admire the think-tanks at the company. They kept pushing the usage of their core product, the one that made them the most valuable web company - the Google search engine. By the way, in 2006, Google had dished out $57 million to have their search bar in the Firefox. This amounted to 85% of Mozilla Corporation's total revenue. [more...]
