Subject RE: CouchDB 2.0 Command Line Options
Date Tue, 18 Oct 2016 15:33:31 GMT
Hi,

I work with Maggie, and had a follow up question about running multiple instances of couchdb
using one binaries directory.  When setting up a cluster, I understand I need to set the identity
of each node in vm.args.  I tried the following to have couchdb look in a different location
for the vm.args file:

	export ERL_FLAGS="-couch_ini /myinstance1/default.ini /myinstance1/local.ini -args_file /myinstance1/vm.args"

However, the couchdb log shows the node identity as: nonode@nohost

Then I tried specifying -name in ERL_FLAGS:

	export ERL_FLAGS="-couch_ini /myinstance1/default.ini /myinstance1/local.ini -name myinstance1@hostname1.domain"

And I still get: nonode@nohost

Finally, I tried specifying -sname in ERL_FLAGS, and this seems to work, but gives a shortname:

	export ERL_FLAGS="-couch_ini /myinstance1/default.ini /myinstance1/local.ini -sname myinstance1"

And now I get: myinstance1@hostname1.  Is there any way I can either point couchdb at my instance's
vm.args file, or I can specify the fully qualified -name option correctly?

Thanks for your help!

Thanks Adam and Jan. We were able to have a few instances running with the workaround.

Thanks Jan, that was a bit cleaner than I realized. It’s a decent workaround. Important
to note that every file you want to be consulted needs to be listed there — the couch_ini
flag will override the default search space entirely.

-a option, I'd have to build CouchDB 2.0 3 times (for example) in order to be able to start
up 3 instances of it on a dev server.

I filed https://urldefense.proofpoint.com/v2/url?u=https-3A__issues.apache.org_jira_browse_COUCHDB-2D3183&d=DQIFaQ&c=nulvIAQnC0yOOjC0e0NVa8TOcyq9jNhjZ156R-JJU10&r=NRwPGDrZo7L6ztGDn5UDKmqnTC5BQkZuuScVw4Hm9u4&m=CvGFCOSao1pTuD2kwqk7Wzhvz_0qdcdqfL_QjL_7E3o&s=LfHg4gH3qRk1Ve2f26b8_Pnj3TqhGxUo0O_duEaLikg&e=
. You can still drop files in the local.d directory and they should take precedence over any
files in default.* as well as local.ini.

you or do you need to point to another location?

looking at the startup scripts in the bin folder there is no code there to accept the "-a"
switch anymore.
