Running PHP 7.0.15 with Caddy (Is there a tutorial available?)

[magikstm]

I want to try to run PHP 7.0.15 on a Centos 7 (minimal) x64 VPS to test it for a few weeks before it replaces another production server using apache.

My usual method to install PHP from source is:

1. wget http://ca2.php.net/get/php-7.0.15.tar.gz/from/this/mirror

2. tar xzf mirror

3. Install compile requirements if they’re not installed yet:
   yum install httpd-devel.x86_64
   yum install libxml2-devel.x86_64
   yum install gcc
   yum install openssl-devel.x86_64
   yum install libpng-devel
   yum install libjpeg-devel
   yum install autoconf

4. Configure php with these:
   ./configure --with-apxs2=/usr/bin/apxs --with-mysqli=mysqlnd --enable-ftp --with-openssl --with-zlib --with-gd --with-jpeg-dir=/usr/lib64 --disable-cli

5. make

6. make install

I do edit some php.ini settings, but let’s say that anything else is left as-is.

How would I enable php inside caddy?

I read these:

Trying to get php working

I have a directive in /etc/caddy/Caddyfile: mysite.com { fastcgi / unix:/run/php-fpm/php-fpm.sock php } I have php-fpm installed and running on Arch. I’m running caddy as a systemd service. My DNS is configured and a mediawiki installation is in the root directory. Navigating to my URL Caddy produces: 502 Bad Gateway

But, it’s still unclear to me how to really do it from source and what steps I would be missing. I’m not familiar with PHP-FPM and it seems that may be needed.

Is there a PHP tutorial available or could someone please tell me steps that may be required beside these to make it work inside caddy?

(*) PHP 7.1.1 is out, but it’s untested on my production server and I’m still keeping 7.0.x for now.

I compiled PHP 7.0.15 with php-fpm by adjusting my configure to this:
./configure --with-mysqli=mysqlnd --enable-ftp --with-openssl --with-zlib --with-gd --with-jpeg-dir=/usr/lib64 --disable-cli --enable-fpm

I then followed that a bit:

How to install PHP 7.1, 7.2 and 5.6 as PHP-FPM & FastCGI for ISPConfig 3...

I did these commands:

• sudo cp /usr/local/etc/php-fpm.conf.default /usr/local/etc/php-fpm.conf

• sudo cp /usr/local/etc/php-fpm.d/www.conf.default /usr/local/etc/php-fpm.d/www.conf

• vi /usr/local/etc/php-fpm.conf
  I uncommented: pid = run/php-fpm.pid
  And adjusted line 125 to: include=/usr/local/etc/php-fpm.d/*.conf

It seemed to still have issues with creating the log file so I did:
sudo touch /usr/local/var/log/php-fpm.log

Then I added php-fpm to run at start:
sudo echo ‘php-fpm’ >> /etc/rc.local

I confirmed it does run at next reboot with “ps aux”.

My caddy file is:
http://0.0.0.0:80 {
root /home/centos/www
fastcgi / 0.0.0.0:9000 php
errors error.log
}

I also tried this:
http://0.0.0.0:80 {
root /home/centos/www
fastcgi / 127.0.0.1:9000 php
errors error.log
}

html renders fine, but php files give “502 Bad Gateway”.

I tried other configs in my caddyfile, but the only other thing I got was “Not found” with this in error.log:
Primary script unknown

I tried looking for more info online, but didn’t find one that solves my issue yet.

Anyone have a tutorial or know how I could possibly make it work? I think I’m only missing something minor.

I’ll read these which I just found:

Primary script unknown

Hi, I am new to Caddy. Trying out got into some trouble. Have gone through the wiki : https://github.com/mholt/caddy/wiki/Troubleshooting-PHP-FPM-and-FastCGI , but seems the issue is not mentioned there. Mostly the problem is as reported in https://github.com/mholt/caddy/issues/611 . I tried some of the options it mentioned, but not successful. These are the configurations I tried localhost:8080 tls off ext .html # Clean URLs errors { log errors.log # Error log 404 error-404.htm…

I did these extra steps:

1. sudo touch /usr/local/var/log/php-fpm.log
2. sudo chmod 777 /usr/local/var/log/php-fpm.log
3. sudo touch /usr/local/var/run/php-fpm.pid
4. sudo chmod 777 /usr/local/var/run/php-fpm.pid
5. php-fpm

And it started working correctly.

It doesn’t start correctly at boot though.

I’ll have to investigate rights further to know why it doesn’t work correctly.

I’ll determine minimal required steps and I’ll share them.

My final working caddy file is:
0.0.0.0:80 {
root /home/centos/www
fastcgi / 127.0.0.1:9000 php
errors error.log
}

I have to admit, I’d personally be looking at something prepackaged, a Docker solution, or even another distro before starting to try and figure out problems with a setup based on php from source on Centos.

Appreciate your efforts to document this one!

[magikstm]

I’ve started on Centos about 5 years ago and all my servers have been with it since then (both dedicated and VPS).

I’ve had 0 downtime, their packaging is really safe and long-term (end of life of Centos 7 being 2024-06) and with good crons and scripts they’re really low maintenance.

All issues I’ve had have been with WordPress vulnerabilities.

I’ll share my final scripts in a few weeks after testing them a bit.

FWIW my monitoring systems are hosted on Centos servers and I’ve never had an issue. Two thumbs up. Just wish they packaged php7.
