As instructed by Till (http://www.howtoforge.com/forums/showpost.php?p=266993&postcount=40) I am creating this new thread (similar to http://www.howtoforge.com/forums/showpost.php?p=266984&postcount=38 and http://www.howtoforge.com/forums/showpost.php?p=266984&postcount=40). Since ISPConfig 3.0.4 supports SNI, I upgraded but the upstream CentOS5 repository does not provide Apache above 2.2.12 and Openssl-0.9.8f upwards. So I manually compiled the binaries from source and upgraded to Apache 2.2.21 and 1 with backward compatibility to 0.9.8f. But when I tried to create a ssl certificate from the ISPCOnfig3 panel, it goes well but nothing seems to have been created as the SSL Certificate field not only remained blank, but the webserver died. Or I just missed something. The error log follows: Please note that in Centos5, I patched the libraries from Version 6 openssl. I saw this thread (http://www.howtoforge.com/forums/showthread.php?t=41597) and to solve above problem, I tried with: 1) replacing the httpd.conf from the previous installation, didn't work! :-( 2) removing the NameVirutalhost:*.80 NameVirtualhost: *.443 and Include lines and changed the Directory to /var/www from default /var/www/html, the webserver starts, but gave me the default apache index pages to my domains. 3) So I did 'php -q update' with new ssl certificate, but when it reconfigures services, the running webserver segfaults. 4) Also tried to disable default certificates in /etc/httpd/conf.d/ssl.conf, but it prevents the server from starting. Any hints or help appreciated! Thanks!
