Ispconfig 3.0 to 3.1 update issue – PHP-FPM and SSL problems

After updating a multi server installation of Ispconfig3 problems occured when editing existing or adding new websites on one of the servers.

• If the site had SSL enabled the apache2 vhosts file for the site (located in /etc/apache2/sites-availible) would get empty values for SSLCertificateFile, SSLCertificateKeyFile and SSLCertificateChainFile fields, causing it to revert to old configuration or not load the site at all. At some point apache2 wouldn’t reload at all so to get it upp the site had to be disabled by removing /etc/apache2/sites-enabled/100-sitename.vhost file.
• If the site was running under PHP-FPM the site would report Internal server error 501 caused by the socket file /var/lib/php5-fpm/webXXX.sock was owned by root and not by the web user. This in turned was caused by the fields listen.owner and listen.group in webXXX.conf (for PHP-FPM) was empty.

Since this was a multi server installation and this problem only occured on one server they could be compared. It turned out that the problem was caused in the directory /usr/local/ispconfig/server/plugins-enabled. The files in this directory should be symbolic links to the corresponding files in /usr/local/ispconfig/server/plugins-available, but after a move of the Ispconfig3 installation from an older server, these links had become real files instead of symbolic links.

This meant that the files in /usr/local/ispconfig/server/plugins-enabled was still Ispconfig 3.0 files while the ones in /usr/local/ispconfig/server/plugins-available was Ispconfig 3.1. To resolve the problem, to be on the safe side, make a backup of /usr/local/ispconfig/server/plugins-enabled and then run:

cd /usr/local/ispconfig/server/plugins-enabled

Verify with ls -l /usr/local/ispconfig/server/plugins-enabled that all your files are symbolic links.
