Macports Apache2 "Could not bind to address"

Question

I have apache2 installed on Mac OS X 10.7.4 via macports

Recently I have not been able to access my localhost directory I get a 404, but I can access 127.0.0.1

I've tried restarting apache:

sudo /opt/local/apache2/bin/apachectl stop
sudo /opt/local/apache2/bin/apachectl start

and I get the following errors:

(48)Address already in use: make_sock: could not bind to address [::]:80
(48)Address already in use: make_sock: could not bind to address [::]:443

I've checked that web sharing is off. It seems like apache is already using these points or the service is not stopping correctly.

How can I find out what is using the ports?

Answer 1

The "lsof" shell command can tell you exactly which process is using which files and socket addresses in the system. Just try a

sudo lsof

or, since the output will be a lot, better

sudo lsof | less

and look for something on the http ports. As usual

man lsof

will give you more information on how to customise the output.

Answer 2

For reference, in Mountain Lion 10.8.2, simply stopping the apache2 service did the trick:

sudo apachectl stop

That way the httpd processes won't restart, and the Macports apache2 server will start fine after that.

Answer 3

In my Mac with Mojave (10.14.1), suddenly Apache couldn't serve IPv4 anymore, then gave me ERROR 403.  I tried to kill all apache (sudo killall httpd)... checking the PID's with

sudo lsof | grep AMP | grep apache

even didn't work... just IPv6 was available... still ERROR 403

What works for me: disable macOS’s built-in Apache server.

sudo launchctl unload -w /System/Library/LaunchDaemons/org.apache.httpd.plist

after that:

sudo apachectl -k restart

be happy :)
