alt-php versions of PHP-FPM fail to start: Address already in use

Symptoms

After a recent update to alt-php, the server is unable to run multiple PHP-FPM services for the alt-php versions. They fail with the following error:

CONFIG_TEXT: ERROR: unable to bind listening socket for address '127.0.0.1:9000': Address already in use (98)

Cause

A recent change in the alt-php versions attempted to make the PHP-FPM services start by default by loading the default configuration. However, all PHP-FPM services from alt-php use the same default configuration, which results in all attempting to use the same default port.

CloudLinux is currently reviewing this upstream with case ID ALTPHP-2485.

Resolution

1. Move aside the default configurations for the alt-php PHP-FPM services that are installed:

   # find /opt/alt -name "www.conf" -exec mv -v {}{,.default} \;

2. Restart PHP-FPM:

   # /scripts/restartsrv_apache_php_fpm
