how to start couchDB? config is READ-ONLY!

some command-line keys to point db to none-default config maybe?

tnx

[nix-shell:~]$ couchdb
Apache CouchDB 1.7.1 (LogLevel=info) is starting.
Error opening log file /nix/store/984kmrqx8sjag6nrbggvz1pa259ma9sy-couchdb-1.7.1/var/log/couchdb/couch.log: read-only file system{"init terminating in do_boot",

just the same thing with yaws :frowning:

[nix-shell:~]$ yaws

       -a FILE
              add configuration FILE to chain

       -A DIR add configuration DIR to chain

       -n     reset configuration file chain (including system default)

nothing from it works :frowning:

#2

Have you checked the many options you can set in configuration.nix?

#3

the piece of my /etc/nixos/configuration.nix file:

 environment.systemPackages = with pkgs; [
     zlib 
     lzip 
     binutils
     coreutils
..... 
     yaws
     couchdb
  ] ;

is that not suffiicient ? name me the options pls

#4

Couchdb: https://nixos.org/nixos/options.html#services.couchdb

Though can’t find anything for yaws using the option search.

#5

“Failed to get option data”

:frowning:

#6

Then use nixos-options services.couchdb and tab complete to navigate it’s children and get explanations of those options

#7

$ man configuration.nix
