![]() ![]() First make sure you have a backup of your current ni data (use the src/scripts/noclook_producer.py -O some_dir along with dumping the postgresql database using pg_dump).you can follow along in `logs/neo4j.log`.Start neo4j service `sudo service neo4j start`.Import database from 2.x `sudo -u neo4j neo4j-admin import -mode=database -database=graph.db -from=/var/opt/neo4j-community-2.1.8/data/graph.db/``.Enable data migration in nf `dbms.allow_format_migration=true` (should probably be disabled after first migration is done).Remove data/databases/graph.db in 3.2 `sudo rm -r /var/lib/neo4j/data/databases/graph.db/`.There are two ways of migrating data for ni, either let neo4j handle the database upgrade or restore ni data from backup. Setup system.d or other way of keeping NEO4j running all the time.Change the password by connecting to the database.You can also choose to run NEO4j as a docker image. If you use the debian package, you might want to change your database path, default is `/var/lib/neo4j/data`. The guide below for migrating assumes you don't do the password creation step, so if you do you can skip the set-defa You can follow the installation steps from the setup guide above. $ sudo update-rc.d -f neo4j-service remove Debian package # Stop the old neo4j installation, and remove it from rc.d Then restart nginx (still remember to setup ssl certificates) Proxy_set_header X-Forwarded-Proto $scheme Proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for Ssl_ciphers "EECDH+AESGCM:EDH+AESGCM:AES256+EECDH:AES256+EDH" Īlias /var/opt/norduni/norduni/src/niweb/niweb/static/ Ssl_certificate_key /etc/ssl/private/ni_nordu_net.key Ssl_certificate /etc/ssl/certs/ni_nordu_net.crt Listen :443 default ipv6only=on # listen for ipv6 ![]() ![]() # sudo openssl req -x509 -sha256 -nodes -days 365 -newkey rsa:2048 -keyout /etc/ssl/private/ni_nordu_net.key -out /etc/ssl/certs/ni_nordu_net.crt # The following configuration should be a good start. $ sudo vi /etc/nginx/sites-available/default Link the configuration in to the correct directory. # less noisy uwsgi logs (especially with sentry) ![]() # for now we run uwsgi in lazy-apps, due to neo4j session problems # the socket (use the full path to be safe Home = /var/opt/norduni/norduni_environmentĭaemonize = /var/log/uwsgi/app/noclook.log Wsgi-file = /var/opt/norduni/norduni/src/niweb/niweb/wsgi.pyĮnv = DJANGO_SETTINGS_MODULE= The following configuration should be a good start.Ĭhdir = /var/opt/norduni/norduni/src/niweb/ If users have an idea of how many database instances you are expecting to be able to create in one large database in their scenario on Aura, we'd love to hear that too.$ sudo vi /etc/uwsgi/apps-available/noclook.ini Please upvote and comment on whether the need you are seeking to solve for with multi-database is a), b), c) or another need we've not heard yet. c) just want to learn about multi-database and how it works in Aura. b) continue my cloud centric development of a technical solution against Neo4j 4 on Aura, and be able to evaluate the feature, without any clear need for it right now. 2) ease of management when integrating with their application, because they perceive they won't have to manage X many small individual databases. This solves 2 needs for end users 1) it's cost effective, they can pay for 1 database but get X many within that. a) build a Graph backed SaaS or application by creating 1 large Aura instance and dividing it into X many smaller databases. Aura users have told us they would like to do 1 of the following things with Neo4j 4 in Aura specifically focussed on the use of the multi-database functionality. Some context on that is covered here : As we get ready to release multi-database in the future, this feature request aims to capture demand and ensure the customer needs are understood. Neo4j 4 on Aura will initially not have multi-database capability by design. ![]()
