I upgraded a minimal squeeze to Wheezy on a vps and performed the installation. http://www.howtoforge.com/perfect-server-debian-wheezy-nginx-bind-dovecot-ispconfig-3 All seemed to be Ok until 12.1 How To Use Multiple PHP Versions (PHP-FPM & FastCGI) With ISPConfig 3 (Debian Wheezy) http://www.howtoforge.com/how-to-us...pm-and-fastcgi-with-ispconfig-3-debian-wheezy cp ioncube/ioncube_loader_lin_5.3.so /opt/phpfcgi-5.3.22/lib/php/extensions/no-debug-non-zts-20090626/ioncube.so It was not found. This happened in the next installation section too. Ispconfig installer came back with PHP Warning: PHP Startup: Unable to load dynamic library '/usr/lib/php5/20100525/memcached.so' - /usr/lib/php5/20100525/memcached.so: undefined symbol: memcached_server_micro_version in Unknown on line 0 and system mail/cron reports the same. server1.example.com comes up OK. Phpmyadmin is not able to connect and squirrelmail just shows a ngix page. https://server1.example.com:8080 produces a 502 gateway error Nginx log 2013/07/16 23:37:49 [crit] 32178#0: *24 connect() to unix:/var/lib/php5-fpm/ispconfig.sock failed (2: No such file or directory) while connecting to upstream, client: xx.xx.xx.xx, server: _, request: "GET / HTTP/1.1", upstream: "fastcgi://unix:/var/lib/php5-fpm/ispconfig.sock:", host: "server1.example.com:8080" BUT THE FILE IS THERE. Does anybody know what is going on? This is the second time I loaded this server and feel that there may be a library, https or other problems. I am sure the memcache seems like it could be straight forward but I am not sure. Is this fixable or should I just stick with Apache?
