Command-line tool and API to quickly setup a MongoDB host or replica set for development purposes, based on the official tutorial.
To use the API:
$ npm install mongo-replica-set
To use the command-line tool install globally:
$ npm install -g mongo-replica-set
Usage: mongo-replica-set [options]Options:-h, --help output usage information-V, --version output the version number-d, --data [folder] Base folder
Thus for a basic setup involving 3
mongod instances simply run:
$ mongo-replica-set>>> Replica set ready: 127.0.0.1:27117, 127.0.0.1:27118, 127.0.0.1:27119
You can then (in a new terminal window) use
mongo to connect to the instances,
which should be running at
localhost:27119 respectively. Eg:
$ mongo --port 27117MongoDB shell version: 2.6.5connecting to: 127.0.0.1:27117/testrs_515_1429031406166:PRIMARY> show dbs;adminlocal 0.281GBrs_515_1429031406166:PRIMARY>
CTRL+C in the original window to terminate the instances and clean up
the replica set.
Note: If any errors occur during initialisation the command will exit and clean up the replica set instances and data folders.
If you specify the number of hosts as 1 then a single non-replica-set host will be launched.
var ReplicaSet = ReplicaSet;var rs = ;// returns a Promisersstart;
You can pass options to the
ReplicaSet constructor, similar to the command-line
var rs =numInstances: 5startPort: 55000baseFolder: '/opt/data'verbose: trueuseColors: false /* Don't use colours when outputting to console */;rsstart;
Once the replica set is running you can obtain the
var conn = rs;// [ '127.0.0.1:55000', '127.0.0.1:55001', '127.0.0.1:55002']
