Hi guys! i'm having a little issue with PHP Version. I followed this guide https://www.howtoforge.com/how-to-u...p-fpm-and-fastcgi-with-ispconfig-3-centos-6.3 and sucefully installed PHP 5.3 and PHP 5.5 in my server (Centos 7 + Nginx). I have configured the others 2 versions in ISPConfig panel, and the only problem is : When i change the version for website example.com , click in save button, the website example.com give me 502 Bad Gateway error. The logs inside /var/www/example.com/log/error.log say : connect() to unix:/var/lib/php5-fpm/web1.sock failed (2: No such file or directory) while connecting to upstream. BUT, if i restart the server or just restart the php services : systemctl restart php-fpm /etc/init.d/php-5.5.13-fpm restart /etc/init.d/php-5.3.22-fpm restart and test, the website works again great with the version i choose. (I use a info.php to check). Someone know what is this issue ? How can we fix it or just configure ISPConfig to restart the services when i change a website PHP Version ? Thank very much !
