Description

In this "multi-u-tree" environment each xxxx library has its own u-tree with its own Apache. (Example: /exlibris/aleph/xxxx/u23_2/aleph/apache .) This is supposed to run on port 48894. When started (with apachectl), there's no error, but it doesn't start -- and nothing is written to the /exlibris/aleph/xxxx/u23_2/alephe/apache/logs ./error_log or ./access_log .

Resolution

The httpd.conf, apachectl, and apachetl_auto must contain the correct path and port#  for apache:

./xxxx/u23_2/alephe/apache/bin/apachectl  
    HTTPD="/exlibris/aleph/a23_2/product/bin/httpd -d /exlibris/aleph/xxxx/u23_2/alephe/apache"
    ...
    PIDFILE=/exlibris/aleph/xxxx/u23_2/alephe/apache/logs/httpd.pid

./apachectl_auto
    source /exlibris/aleph/xxxx/u23_2/alephe/aleph_start
    
./xxxx/u23_2/alephe/apache/conf/httpd.conf
    ServerName dc02kg0559na:48894
    ServerRoot "/exlibris/aleph/xxxx/u23_2/alephe/apache"

Then restart apache.
