The page "Additional_Instances" has been deleted by JoanTouzet: https://wiki.apache.org/couchdb/Additional_Instances?action=diff&rev1=2&rev2=3 Comment: very outdated - <<Include(EditTheWiki)>> - = Setting up Additional CouchDB Instances = - - While most of the time, it's sufficient to have different applications stored in separate design docs, or in separate DBs, sometimes you just need a separate instance. For example, SSL certificates and port/ip addresses are bound to the erlang instance, not the individual database. - - This is the file structure you'll need to create: - - * {{{lib/couchdb}}} for the couchdb data files - * {{{{log,run}/couchdb/}}} are self explanatory - * and a single {{{etc/couchdb/local.ini}}} which will over-ride the system-installed CouchDB {{{default.ini}}} at runtime - - {{{ - couchdb - ├── etc - │ └── couchdb - │ └── local.ini - └── var - ├── lib - │ └── couchdb - ├── log - │ └── couchdb - └── run - └── couchdb - }}} - - * Assuming you adapt OLD & NEW as appropriate, here's how to set it up: - - {{{ - % OLD=/usr/local - % NEW=/tmp/couchdb - - % mkdir -p $NEW/etc/couchdb/ - % mkdir -p $NEW/var/{lib,log,run}/couchdb/ - - % cp $OLD/etc/couchdb/local.ini $NEW/etc/couchdb/ - - % tree -l $NEW - [...tedious output omitted...] - }}} - - * Don't forget to {{{chown/chmod}}} all these dirs and files so that the future CouchDB user has r/w permissions. - * Finally, you then need to adapt {{{local.ini}}} for these new locations, and obviously include a different port/bind_address combo - - {{{ - [couchdb] - database_dir = /tmp/couchdb/var/lib/couchdb - view_index_dir = /tmp/couchdb/var/lib/couchdb - uri_file = /tmp/couchdb/var/run/couchdb/couch.uri - - [httpd] - port = 5985 - bind_address = 0.0.0.0 - - [log] - file = /tmp/couchdb/var/log/couchdb/couch.log - }}} - - You can test this by running couchdb (in my case interactively using -i): - {{{ - % couchdb -i -a /tmp/couchdb/etc/couchdb/local.ini - }}} - - And Relax. - - == Caveats == - - The original {{{local.ini}}} is still included in the configuration chain. You can see this by running: - - {{{ - % couchdb -i -a /tmp/couchdb/etc/couchdb/local.ini -c - - /usr/local/etc/couchdb/default.ini - /usr/local/etc/couchdb/local.ini - /tmp/couchdb/etc/couchdb/local.ini - }}} - - This means anything (for example server admins (in {{{[admins]}}} or SSL certificates in {{{[ssl]}}}) that are not over-ridden in your newer config file will apply. If you've got server admins created then don't forget to prune them in the duplicated local.ini if needed. -
