macOS closes apache httpd and starts it up

macOS installs the apache httpd service by default, and it will start automatically at boot, occupying port 80. If you do not need the httpd service, you can close the apache httpd service and cancel the automatic startup at boot.

Execute the following command in the terminal:

sudo lsof -i:80

Check which process is using port 80

The results are as follows:

COMMAND PID USER FD TYPE DEVICE SIZE/OFF NODE NAME
httpd 18183 root 4u IPv6 0x455b25acea0abc45 0t0 TCP *:http (LISTEN)
httpd 18187 _www 4u IPv6 0x455b25acea0abc45 0t0 TCP *:http (LISTEN)

Execute the shutdown startup command

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

The results are as follows:

/System/Library/LaunchDaemons/org.apache.httpd.plist: Operation now in progress

The startup command is as follows:

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

start apache command

sudo apachectl start

restart apache command

sudo apachectl restart

stop apache command

sudo apachectl stop
