Use the following information if you cannot start your server:
Verify that the ServerName directive in sps_home/secure-proxy/httpd/conf/httpd.conf corresponds to the name of your server.
Verify that the server is not already running by executing one of the following:
ps -ax|grep http on BSD compatible systems
ps -elf|grep http on System V release 4 compatible systems
If this results in a list of processes, stop the running server before starting your new server.
Check the log files in the directory sps_home/secure-proxy/httpd/logs
Verify that the SSLCertificateFile and the SSLCertificateKeyFile directives in the httpd.conf file point to your certificate and key files. The file is in the directory sps_home/secure-proxy/httpd/conf
Determine whether you are using non-IP-based virtual hosts. SSL requires IP-based virtual hosts.
Verify that no other server is running on the default port for the SPS. The default port is specified in the httpd.conf file.
If you using SSL, be sure you have generated a key and certificate before starting the server, otherwise you will get an error.
