Upgraded to PHP 7.3 now nothing works

walterbyrd · 11-17-2021, 10:36 AM

I am running Devuan and lighttpd.

Code:

# uname -a
Linux servername 4.19.0-18-amd64 #1 SMP Debian 4.19.208-1 (2021-09-29) x86_64 GNU/Linux

I upgraded from php 7.0 to php 7.3. Now php does not seem to work at all.

Code:

# service php7.3-fpm status | grep running
php-fpm7.3 is running.
# ps -aux | grep httpd
www-data  1804  0.0  0.0  13024  2760 ?        S    05:23   0:00 /usr/sbin/lighttpd -f /etc/lighttpd/lighttpd.conf

My phpinfo.php script is fairly simple.

Code:

# ls -l phpinfo.php
-rwxr-xr-x 1 www-data www-data 20 Nov 17 09:12 phpinfo.php
# cat phpino.php
<?php phpinfo(); ?>

But when I try to bring up phpinfo.php, in my browser, I get "503 Service Not Available". HTML scripts will run.

Please show us the complete, ungrepped output.

Somebody recently reported a very similar problem: PHP7.x was apparently running, but no pid was found. I cannot find it right now because they didn't put PHP in the title...

# service php7.3-fpm status
[ ok ] php-fpm7.3 is running.

That is the complete, ungrepped output.

Generally speaking, I would restart ALL affected services after the PHP upgrade - the server itself (httpd), all php services, etc. Possibly even in a certain order, or twice to be sure.

A web search for the error message returns this PHP-related result:

Good first troubleshooting steps I'd say.
More general, but also more detailed troubleshooting:

The server has been restarted many times since the error started. That does nothing.

I tried this:

# lighttpd -f /etc/lighttpd/lighttpd.conf
2021-11-26 16:26:37: (network.c.313) can't bind to socket: 0.0.0.0:80 Address already in use

I'm not sure how that makes sense, or what to do about it.

It would have been polite to inform people that you've given up on lighttpd and are now trying to get Apache working, so they may waste time responding to a redundant thread.

Got rid of lighttpd, and removed all PHP. Then re-installed PHP, which installs Apache. Same issue.

I should have mentioned that I was using lighttpd. I didn't because I felt the problem is with PHP, not the webserver. The webserver serves up HTML just fine. But PHP does not work at all.

I have re-installed a few times. I have checked, and re-checked the config files. I am not finding anything in the log files either.

PHP is well-known for "breaking changes" between language versions: things get "deprecated" and removed completely. Maybe this happened again?
