Mac OS Big Sur - Homebrew Apache - 48)Address already in use: AH00072: make_sock: could not bind to address 0.0.0.0:8080

Question

I have a problem with Apache on Mac OS Big Sur. After the OS update, the Apache (using Brew) doesn't work anymore. So I have decided to uninstalled the httpd Formula. Then tested is the preinstalled version of Apache works and it does.

1. So I have stopped the preinstalled Apache sudo apachectl stop
2. Unloaded launcher sudo launchctl unload -w /System/Library/LaunchDaemons/org.apache.httpd.plist 2>/dev/null
3. Updated the Homebrew
   • brew update
   • brew doctor
   • brew upgrade
4. Installed the httpd again brew install httpd (installed successfully)
5. Started the httpd sudo brew services start httpd

However checking the status sudo brew services list I can see that the httpd service has status error. When I try to start apache using sudo apachectl start I'm receiving the error:

(48)Address already in use: AH00072: make_sock: could not bind to address 0.0.0.0:8080
no listening sockets available, shutting down
AH00015: Unable to open logs

I've checked if maybe there is something else running on the 8080 port lsof -i TCP:8080 but it's not.

I've checked which Apache is used (which apachectl) and it seems to be the right one (/usr/local/bin/apachectl)

No matter what port I'm trying to use, always there is an error that the address is already in use.

Does anyone has any idea how to fix this problem?

Answer 1

I was facing the same problem. It appears that bindings to INADDR_ANY (0.0.0.0) fail.

To circumvent the bind error, I changed in /usr/local/etc/httpd/httpd.conf the following line:

Listen 8080

to:

Listen 127.0.0.1:8080

Afterwards, I could start apache without the bind error, using the following command:

sudo apachectl -k start

Answer 2

I had the same problem, but needed to run apache on port 80. First I got it working on 8080 with the solution above by @FrankStappers with:

Listen 127.0.0.1:8080
ServerName localhost:8080

Next I tried changing the port to 80 in both Listen and ServerName directives. Restarting left me with these errors:

(13)Permission denied: AH00072: make_sock: could not bind to address 127.0.0.1:80
no listening sockets available, shutting down
AH00015: Unable to open logs

Ultimately changing Listen and ServerName as follows fixed it:

Listen 0.0.0.0:80
ServerName localhost
