在同一台机器上使用两个不同的PHP版本

Question

I'm using ubuntu 16.0.4 having nginx and php7.0-fpm installed on it. Is it possible to use another version of php for another project at the same time?

How should I change my nginx config file?

Answer 1

I usualy change the fastcgi_pass socket variable into my nginx conf file.

 location ~ \.php$ {
       ...

        fastcgi_pass unix:/var/run/php/php7.2-fpm.sock;

       ....
    }

Check the sock location for your php version. Mine (using Debian 9) can be located into /var/run/php/

cd /var/run/php

I currently have both php fpm 5.6 and 7.2 installed on my system, and the list command will output both php5.6-fpm.sock and php7.2-fpm.sock files.

You could then substitute the sock pointer into the nginx file:

location ~ \.php$ {
    ...
    fastcgi_pass unix:/var/run/php/php5.6-fpm.sock;
    ....
}

Remember to reload nginx afterwards:

sudo systemctl restart nginx
