git clone https://github.com/ether-camp/ethereum-harmony
cd ethereum-harmony
- Run Service:
gradlew runMain
( live network by default or any other environment )
Navigate to web view http://localhost:8080
JSON-RPC is available at either http://localhost:8545/rpc
or http://localhost:8545
In order to provide ability to disable unneeded features, any of app modules could be disabled: web, contracts, rpc. Check configuration for more info.
Run RPC only: gradlew runMain -PrpcOnly
(*) Use gradlew runMain -Dserver.port=9999
option to change web interface port number.
.
Environment | Run | ... |
---|---|---|
Main | gradlew runMain |
Start server connecting to Main network |
Ropsten | gradlew runRopsten |
Start server connecting to Ropsten network |
Classic | gradlew runClassic |
Start server connecting to Ethereum Classic network |
Private | gradlew runPrivate |
Start server, no network connection, single miner running |
Custom | gradlew runCustom |
Start server connecting to custom network (check custom network) |
.
git clone https://github.com/ether-camp/ethereum-harmony
cd ethereum-harmony
- Run Service with custom config:
gradlew runCustom -Dethereumj.conf.file=/path/to/custom.conf
- It is also possible to use CLI to pass parameters:
gradlew runCustom -Dpeer.networkId=10101 -DgenesisFile=/path/to/custom/genesis.json -Dpeer.discovery.enabled=false -Dpeer.active.0.url=enode://0f4a5f92835a4604ecd9639ddcfb86d2a2999ad9328bc088452efffe4a7c6cd0eaaef77c779dc56fc1d0f21cd578eeb92cb5@23.101.151.28:30303
Note: parameters that haven't been substituted by either custom config or CLI will be supplied from ethereumj.conf
Format of the file should be the same as of ethereumj.conf. It also works to specify only necessary config parameters.
An example:
genesisFile = /path/to/custom/genesis.json
database.dir = database-private
peer {
networkId = 10101
listen.port = 50505
discovery.enabled = false
active = [
{url = "enode://6ce05930c72abc632c58e2e4324f7c7ea478cec0ed4fa2528982cf34483094e9cbc9216e7aa349691242576d552a2a56aaeae426c5303ded677ce455ba1acd9d@13.84.180.240:30303"}
{url = "enode://20c9ad97c081d63397d7b685a412227a40e23c8bdc6688c6f37e97cfbc22d2b4d1db1510d8f61e6a8866ad7f0e17c02b14182d37ea7c3c8b9c2683aeb6b733a1@52.169.14.227:30303"}
]
}
sync.fast.enabled = false
If you run Harmony without using Gradle, add -Dethereumj.conf.res=harmony.conf
to command line, so Harmony properties will be applied to system context too.
If you use some custom resource file as config, just add -Dethereumj.conf.res=harmony.conf,custom.conf
to java exec command so both will be applied.
