I have been googling for the past few hours but I simply can't get my apache on wamp to start. My skype isn't running, and the test port 80 shows it isn't being used by anything. Before this happened, I was trying to add a new vhost, but now I have reverted back all of the files where I made changes. Anyway to debug why apache won't start?
Clicking on start/resume service for apache doesn't show any errors either.
Also just in case, I am running Win7 64bit
If you have an issue in the httpd.conf or any files included by it there are a couple of ways to find out what the problem is
First look at your Windows Event Viewer. Click on the Windows link in the menu on the left, and then submenu Applications.
Look for messages from Apache with the red error icon.
Secondly, open a command window, then CD into \wamp\bin\apache\apache2.x.y\bin, replace x,y with your actual version. Now you can run this command to get Apache(httpd) to vaidate the httpd.conf file.
httpd.exe -t
This should give errors with line numbers related to the http.conf file. It stops on the first error, so you will have to keep running it and fixing the error and then run it again until it gives the all OK message.
That is what I did and it helped me to find out what my Apache-PHP needed:
C:\Users\Admin>cd C:\wamp\bin\apache\apache2.4.9\bin
C:\wamp\bin\apache\apache2.4.9\bin>httpd -t
Syntax OK
C:\wamp\bin\apache\apache2.4.9\bin>httpd -k start
[Thu Apr 23 14:14:52.150189 2015] [mpm_winnt:error] [pid 3184:tid 112]
(OS 2)The system cannot find the file specified. : AH00436:
No installed service named "Apache2.4".
C:\wamp\bin\apache\apache2.4.9\bin>
The most simple solution:
Uninstall and reinstall WAMP (do not even try to set it up on top of existing installation - it would not help)
P.S.
If you wonder how did I get to this situation, here is the answer: I was trying to install WAMP and it throws me an error in the middle of installation saying:
httpd.exe - System Error
The program can't start because MSVCR110.dll is missing from your computer.
Try reinstalling the program to fix this problem.
OK
I got and installed Microsoft Visual C++ 2012 Redistributable from here http://www.microsoft.com/en-us/download/details.aspx?id=30679#
And it gave me the "dll" and the MYSQL started working, but not Apache. To make Apache to work I uninstalled and reinstalled WAMP.
Use apaches startup debug tool from command:
httpd.exe -e warn
- press Win+R
- type
cmdand press enter - goto directory which contains your apache
httpd.exefile. for example if your wamp is installed ine:\wamptypecd /d e:\wamp\bin\apache\ApacheX.X.X\binin cmd and press enter. - type
httpd.exe -e warn(orhttpd.exe -e debugfor more details) to see error message about problem which is prohibiting apache to start.
Invalid Command '80HostnameLookups' , perhaps misspelled or defined by a module not included in the server configuration
I got this error when I debug the issue (wamp server was not going online) by the procedure defined by @RiggsFolly. Just comment the line 80HostnameLookups Off by changing it to #80HostnameLookups Off.
This solution worked for me and apache starts running.
Note:80HostnameLookups Off can be found on line 222 of httpd.conf file located in C:\wamp\bin\apache\apache2.4.9\conf
phpmyadmin.conf opened with apacheconf.exe and contents chained so you must do the following:
- copy contents of phpsysinfo.conf [C:\wamp\alias]
- paste into phpmyadmin.conf [C:\wamp\alias]
- change
Alias /phpsysinfo "c:/wamp/apps/phpsysinfo3.1.12/"toAlias /phpmyadmin "c:/wamp/apps/phpmyadmin4.1.14/" - change
<Directory c:/wamp/apps/phpsysinfo3.1.12/ />to<Directory c:/wamp/apps/phpmyadmin4.1.14/ />
its worked for me.
My solution was that 2 .dll files(msvcp110.dll, msvcr110.dll) were missing from the directory : C:\wamp\bin\apache\apache2.4.9\bin So I copied these 2 files to all these locations just in case and restarted wamp it worked C:\wamp C:\wamp\bin\apache\apache2.4.9\bin C:\wamp\bin\apache\apache2.4.9 C:\wamp\bin\mysql\mysql5.6.17 C:\wamp\bin\php\php5.5.12
I hope this helps someone out.
Sometimes it is Skype or another application "Holding" on to port 80. Jusct close Skype
My solution on Windows 10 was just to stop IIS (Internet Information Services).
If Apache is installed as a Windows service, any errors will show up in the Windows System event log. To view the System event log, navigate to Windows Administrative Tools->Event Viewer and open the System log in the Windows Logs folder. Or, you can see the same errors by running httpd.exe at the command line. In my case, httpd.exe is located here: C:\Bitnami\wampstack-5.6.26-2\apache2\bin.
If there is a problem with starting Apache, most likely the problem can be fixed by editing the httpd.conf file located in the \apache2\conf folder. As already suggested, you can check the syntax of the httpd.conf file by running httpd.exe -t at the command line.
I found that the I had to
Change
SetEnv PATH "C:\Bitnami\wampstack-5.6.26-2\apache2\bin;${PATH}"in httpd.conf
to
SetEnv PATH "C:\Bitnami\wampstack-5.6.26-2\apache2\bin;%PATH%"
I had the same problem. My port 80 was not in use.
After thorough research, all I did was to download Update for Universal C Runtime.
Once installed and my PC restarted, all was OK.
I was having the same problem, the mysql service was starting but not the apache service, the main problem about that is one of your virtual hosts isn't config. correctly, all i did was deleted the virtual host that i created "D:\wamp\bin\apache\apache2.4.23\conf\extra\httpd-vhosts, restarted all services apache service started working correctly and so i just went to localhost and added a virtual host automatically and so it worked!!
I was having same problem.
I followed this steps, problem solved.
run command line (CMD) with Administrator Permission.
cd c:/wamp64/bin/apache/apache2.4.27/bin
httpd.exe -k uninstall
httpd.exe -k install
at last restart all services from wamp system tray icon
