Alas, SELinux is not in use.
I am thinking that the apache OCF module is not starting up apache with the modules that it needs.
Again, startup with 'systemctl start apache' brings up the http daemons, so we know that the Apache configuration is clean.
But if I enable trace and run the ocf script by hand:
/usr/lib/ocf/resource.d/heartbeat/apache start ; echo $?
Part of the output is Apache syntax errors that aren't flagged in the regular startup:
+ 14:57:10: ocf_run:443: ocf_log err 'AH00526: Syntax error on line 22 of /etc/apache2/vhosts.d/aqvslookup.conf: Invalid command '\''Order'\'', perhaps misspelled or defined by a module not included in the server configuration '
The 'Allow' and ' AuthLDAPURL' commands are also flagged as invalid.
The /etc/sysconfig/apache2 module parameter includes the relevant modules:
APACHE_MODULES="actions alias auth_basic authn_file authz_host authz_groupfile authz_core authz_user autoindex cgi dir env expires include log_config mime negotiation setenvif ssl socache_shmcb userdir reqtimeout authn_core php5 rewrite ldap authnz_ldap status access_compat"
Why are they invoked properly from systemctl but not from ocf?
