Installation Guide
|
|
==================
|
|
|
|
Prerequisite
|
|
============
|
|
|
|
To follow up this guide you need to have Golang installed, since we are going to use it to compile the code itself. you can find a tutorial on how to install Golang here: https://golang.org/doc/install.
|
|
|
|
Additionally, you may want to have git installed (but you can also download directly from Github): https://git-scm.com/book/en/v2/Getting-Started-Installing-Git.
|
|
|
|
Compiling
|
|
=========
|
|
|
|
In order to download the code and compile you need the following commands:
|
|
|
|
.. code-block:: sh
|
|
|
|
$ git clone https://github.com/ledgerwatch/erigon
|
|
|
|
$ cd erigon
|
|
|
|
$ make
|
|
|
|
Running
|
|
=======
|
|
|
|
After this is done, you can run Erigon by executing.
|
|
|
|
.. code-block:: sh
|
|
|
|
$ ./build/bin/erigon
|
|
|
|
what this will do is start a sync process in mainnet.
|
|
|
|
RPC Daemon
|
|
==========
|
|
|
|
Unlike Go-Ethereum (geth), Erigon has a separate RPC service called rpcdaemon, this service is used for managing JSON RPC API. In fact, they are not present in Erigon with `--rpc` flag but we have to start a separate service for it. first of all Erigon must give access to the rpcdaemon to the database through an API. so we need to run Erigon with the flag **--private.api.addr** which by convention should be set to **localhost:9090**.
|
|
|
|
.. code-block:: sh
|
|
|
|
$ ./build/bin/erigon --private.api.addr=localhost:9090
|
|
|
|
then to run the rpcdaemon attached to our node we just run
|
|
|
|
.. code-block:: sh
|
|
|
|
$ ./build/bin/rpcdaemon
|
|
|
|
now we can make use of the JSON RPC API at localhost:8545. in order to change the address in which we serve the API we can use the flag **--http.api=<something>** |
