I just find out that when I simply type 'localhost' in the url without anything more in the path, the browser displays a message from a local backend test project in Express that I've made days ago.
I'm trying to stop this process.
I was sure that to have started this server on port 3001 but when I try to kill it , it says that there is no process running on this port.
I tried to kill 8080 as well, but the message is still displayed.
Obviously, I refreshed the page, I tried on several different browser, even restarted my computer.
How can i determine which port is running?
How can I stop the process?
[Edit]:
Here's what I keep receiving :
<html><head></head><body><h1>It works!</h1>
</body></html>
You could use lsof:
lsof -i #localhost
Can you try this command :
sudo lsof -nP -i4TCP:80
I woke up for work and started receiving this error, but I can't find this specific error anywhere.
I tried using netstat -ano to find any instances running on the aformentioned port, and also the ports I run Tomcat on:
HTTP port: 8090
JMX port: 1099
But no processes are running on any of the three ports. Any ideas?
Oh,my! This helps me a lot
// first,close your idea
// then, run cmd as administator
net stop winnat
net start winnat
// launch your idea
Before,I have tried this,but it doesn't work
ipconfig /flushdns
netsh winsock reset
As for me,the problem begin when i use idea to debug my web application.
Then i find where the port configured and change to another port.
this link might be helpful
net stop winnat
launch your idea tomcat
net start winnat
First time I installed the package xampp I had many problems (like everyone who tries to use this programs and tries to create a website!)
I had made some researches on the web to find the solution to make Apache work: I setted the usual port 80 to 8080.
Now everytime I want to access to control panel of xampp or access to the DBMS MySQL I have always to add to the url ":8080" after "localhost".
My first question is: is it possible not to write ":8080" after the "localhost", maybe changing some settings I don't know where or in what file? (ex: "localhost:8080/xampp/" => "localhost/xampp")
Another thing: what could be the problems if apache is listening on the port 8080 instead of the usual one? (I don't have many experience in this field...)
Thank you in advance!
The only way to not write :8080 in the address bar is to make it work with the default port, which is :80. If the server does not want to start on that port it's probably because another program is already using it.
netstat -a -n -o | findstr ":80 "
With this command you can see which program is using your 80 port.
I have a Sinatra app that I run as a daemon, using Apache port-forwarding to mediate between port 80 and port 7655. This has been working fine in the past. Today, not so well. I cannot figure out why.
Problem: sudo ruby my_process.rb returns:
/var/lib/gems/1.9.1/gems/eventmachine-1.0.0/lib/eventmachine.rb:526:in `start_tcp_server': no acceptor (port is in use or requires root privileges) (RuntimeError)
Tried: updating all system packages, updating all gems. No help (except for the more clear error message from eventmachine).
When I run sudo lsof -i :7655 I get nothing back. When I run sudo ps aux I don't see any Ruby processes at all. Which I find highly irregular, given the nature of the error message!
So is there something I'm missing in finding out why the port is unavailable?
Also:
Tried changing ports, nothing. I wonder if it is related to "localhost"? When I ping localhost I get all dropped packets. That doesn't seem normal.
Turns out these two lines in the main Sinatra script provided the most information:
set bind: "localhost"
set port: 7655
The problem was with localhost. The loopback interface was not properly configured. ifconfig showed the lo interface, but it hadn't been assigned the IP 127.0.0.1. To resolve, ran the following commands in the shell (on an Ubuntu Linux system):
ifdown lo
ifup lo
When you close term sometime you forget to stop [CTRL+C] the actual server, just run the following command to kill all ruby process like sinatra, and run-it again
killall ruby
You can see your actual ruby process by running
ps -ef | grep ruby
During the installation of Apache2 I got the following message into cmd window:

and after installing everything look fine, but it isn't. If I try to start service I got the following message:

Does anyone have the same problem, or could help me.
There is some other program listening on port 80, usual suspects are
Skype (Listens on port 80)
NOD32 (Add Apache to the IMON exceptions' list for it to allow apache to bind)
Some other antivirus (Same as above)
Way to correct it is either shutting down the program that's using the port 80 or configure it to use a different port or configure Apache to listen on a different port with the Listen directive in httpd.conf. In the case of antivirus configure the antivirus to allow Apache to bind on the port you have chosen.
Way to diagnose which app, if any, has bound to port 80 is run the netstat with those options, look for :80 next to the local IP address (second column) and find the PID (last column). Then, on the task manager you can find which process has the PID you got in the previous step. (You might need to add the PID column on the task manager)

If you want to Disable Skype from listening on port 80 and 443, you can follow the link http://www.mydigitallife.info/disable-skype-from-using-opening-and-listening-on-port-80-and-443-on-local-computer/
Run the httpd.exe from the command line to get an accurate description of the problem.
I had the same error message and it turned out to be a miss configured ServerRoot path. Even after running setup_xampp.bat the httpd.conf had the wrong path.
My error.log was empty and starting the service does not give an informative error message.
the better way to resolve the issue is change the port number in Apache2\conf\httpd.conf . Change the port number as fallows::: Listen 8888 and ServerName machinename:8888 .Restart the Apache server after changing the port number.
I had the same problem. I checked netstat, other processes running, firewall and changed httpd.conf, stopped antivirus, But all my efforts were in vain. :(
So finally the solution was to stop the IIS. And it worked :)
I guess IIS and apache cant work together. If anybody know any work around let us know.
Run the httpd.exe from the command line, as Tim mentioned. The path to PostgreSQL changed, nothing else was running on Port 80 and I didn't see anything in the error.log file.
I clone my boot drive/partition once the base is setup so I don't have to spend three days installing and retweaking everything. Turns I had reinstalled my WAPP stack and used very specific names/versions for PostgreSQL. Windows will not return a specific error message unless you run the command from the command line.
Follow this step it will works fine.
Go to Control panel-->Programs and features-->click Turn Windows features on and off--> see IIS is Checked Or Not If checked please unckeck IIS and restart the computer.After that Open services see Web Deployement Agent Service status if its started please stop.And also see WampAppache and WampSqlID if its not started please start manually. it will works for me.
Hi i also meet this problem today.
And the log error in the Event viewer is as following
The Apache service named reported the following error:
1.Wrapper php-cgi.exe cannot be accessed: (720005)Access is denied.
2.apache service monitor:the requested operation has failed
It is actual the access problem.So the solution as flowing is help me
change the php-cgi.exe security properties
not inheit from parent the permission...
please add the everyone user
if appache and IIS both are running at a time then there is a posibility to hang the apache service,,,,
when i stopped all IIS websites once and then restarted apache service and it works for me....Jai...
Windows Vista Home Premium operating system issue: The easiest way to resolve the issue is to change the port number in Apache2\conf\httpd.conf.
Change the port number at the following lines. 'Listen' from 80 to 8888 and 'ServerName' machinename (ex:localhost) from 80 to 8888. Save then close. Open up Apache Service Monitor and restart service or go to Computer Management > Services and locate Apache 2.2 and start or restart.
Remove apache from Control Panel and delete the apache folder from Program Files and restart the machine, then install apache again. This will solve the problem; if not do the following: Install IIS if not installed, then start IIS and stop it ... Using services start apache service... enjoy apache.
I've had this problem twice. The first problem was fixed using the marked answer on this page (thank you for that). However, the second time proved a bit more difficult.
I found that in my httpd-vhosts.conf file that I made a mistake when assigning the document root to a domain name. Fixing this solved my problem. It is well worth checking (or even reverting to a blank copy) your httpd-vhosts.conf file for any errors and typo's.
if you are using windows os and believe that skype is not the suspect, then you might want to check the task manager and check the "Show processes from all users" and make sure that there is NO entry for httpd.exe. Otherwise, end its process. That solves my problem.
Yes , i had to change the port :80 to :90 as port :80 was busy by some other system resource.
You can see the logs in the folder of Apache2.2\logs
Thanks,
Always double check httpd.conf to see if document root is correctly pointing to an existing folder
#if you have c:\your-main-folder\www\
DocumentRoot "c:/your-main-folder/www/"
#if you have c:\your-main-folder\www\sub-folder\
DocumentRoot "c:/your-main-folder/www/sub-folder/"
DocumentRoot points to a folder that must exist in your drive.
I had the same issue. when i restarted my wamp it turns to Yellow color icon but not green.
In services i stop all sql server services. after that it works for me..
Two thinks that should must be take care.
1 ) port should be different
2 ) stop those services which can be on port 80
i faced the same issue, in my case i needed to add module in httpd.conf
the file was incomplete with incorrect keywords ( like LoadModule )
go to command line, go to C:\Apache24\bin
C:\Apache24\bin > httpd.exe
the reason for the error can be known from the output of the above command
Thanks for the help guys. I found another culprit. Recently SimplifyMedia added a photo sharing option. Apparently it too uses port 80 and prevented Apache from starting up. I hope this helps someone out.
Me also coming the same problem. The solution is goto add or remove programes then click the turn windows features on or off. Turn off the IIS. That is turn off the 'Internet information services' and 'Internet information service removable web core'. I chosed the remaining features are on. Computer will ask to restart the system. Restart ur computer and then install the apache http server. I got it. Server succesfully working...
For me, this was the result of having set the document root (in httpd.conf) to a directory that did not exist (I had just emptied htdocs of a previous project).
Windows 10 - administrator account
I needed to switch the account to an admin type account, in windows services
httpd.exe -k install
fails to add setup with enough user rights.
