Services
The following table lists the services provided by romulus and the location of the relevant configuration files.
| Service | Configuration Files/Folder |
|---|---|
| Apache2 (web server) | /etc/apache2 |
| GOsa² | /etc/gosa, mainly /etc/gosa.conf |
| DokuWiki | /etc/dokuwiki |
| OpenLDAP | cn=config and /etc/ldap |
| OpenSSH | /etc/ssh |
| OMERO | /usr/local/share/omero/OMERO.server/etc |
| OMERO.figure | /usr/local/share/omero/OMERO.server/lib/python/omeroweb/figure |
| iSCSI Initiator | /etc/iscsi |
Storage
romulus has its root directory / mounted on a 600 GiB RAID 1 array at /dev/sda. Addtionally, a 5.9 TiB RAID 6 array on remus (192.168.231.218) consisting of 12 Seagate Cheetah ST3600057SS (600 GB, 15000 rpm) is connected via Ethernet and iSCSI at /dev/sdb and mounted on /srv.
The iSCSI connected mount point /srv holds the managed repository of OMERO and thus all uploaded image files and files attached to OMERO images/projects/datasets. Additionally, /srv holds part of the regularly taken system and storage backup for synchronization with rheasilvia.
Web Server
OMERO, the DokuWiki platform and GOsa² all run on an Apache 2.4.7 web server. All configuration files have been adapted to the syntax necessary for Apache servers >= 2.4 (e.g. require all granted instead of Allow from all, etc.), which was necessary since most examples for web services are still tailored to Apache 2.2.
/etc/apache2/sites-available contains configuration files for GOsa² and for OMERO/DokuWiki. The latter two are combined inside omero-ssl.conf, since they both run on romulus.oice.uni-erlangen.de. The GOsa² service can be reached via its own domain name gosa.oice.uni-erlangen.de and is consequently configured in its own configuration file gosa-ssl.conf
