Intro for new developers and witnesses
|
|
------------------------
|
|
|
|
This is a quick introduction to get new developers and witnesses up to speed on Peerplays blockchain. It is intended for witnesses plannig to join a live, already deployed blockchain.
|
|
# Building on Ubuntu 18.04 LTS and Installation Instructions
|
|
|
|
The following dependencies were necessary for a clean install of Ubuntu 18.04 LTS:
|
|
|
|
sudo apt-get install gcc-5 g++-5 cmake make libbz2-dev libdb++-dev libdb-dev libssl-dev openssl libreadline-dev autoconf libtool git
|
|
|
|
## Build Boost 1.67.0
|
|
|
|
|
|
|
|
mkdir $HOME/src
|
|
cd $HOME/src
|
|
export BOOST_ROOT=$HOME/src/boost_1_67_0
|
|
sudo apt-get update
|
|
sudo apt-get install -y autotools-dev build-essential libbz2-dev libicu-dev python-dev
|
|
wget -c 'http://sourceforge.net/projects/boost/files/boost/1.67.0/boost_1_67_0.tar.bz2/download' -O boost_1_67_0.tar.bz2
|
|
[ $( sha256sum boost_1_67_0.tar.bz2 | cut -d ' ' -f 1 ) == "2684c972994ee57fc5632e03bf044746f6eb45d4920c343937a465fd67a5adba" ] || ( echo 'Corrupt download' ; exit 1 )
|
|
tar xjf boost_1_67_0.tar.bz2
|
|
cd boost_1_67_0/
|
|
./bootstrap.sh "--prefix=$BOOST_ROOT"
|
|
./b2 install
|
|
|
|
|
|
|
|
## Building Peerplays
|
|
|
|
|
|
export BOOST_ROOT=/root/boost_1_67_0
|
|
export CC=gcc-5 ; export CXX=g++-5
|
|
cd $HOME/src
|
|
git clone https://github.com/peerplays-network/peerplays.git
|
|
mkdir $HOME/peerplays/build; cd $HOME/src/peerplays/build
|
|
git submodule update --init --recursive
|
|
cmake -DBOOST_ROOT="$BOOST_ROOT" -DCMAKE_BUILD_TYPE=Release ..
|
|
make -j$(nproc)
|
|
|
|
make install # this can install the executable files under /usr/local
|
|
|
|
|
|
Rest of the instructions on starting the chain remains same.

|
Starting A Peerplays Node
|
|
-----------------
|
|
|
|
For Ubuntu 14.04 LTS and up users, see
|
|
[this](https://github.com/cryptonomex/graphene/wiki/build-ubuntu) and
|
|
then proceed with:
|
|
|
|
git clone https://github.com/pbsa/peerplays.git
|
|
cd peerplays
|
|
git submodule update --init --recursive
|
|
cmake -DBOOST_ROOT="$BOOST_ROOT" -DCMAKE_BUILD_TYPE=Release .
|
|
make
|
|
./programs/witness_node/witness_node
|
|
|
|
Launching the witness creates required directories. Next, **stop the witness** and continue.
|
|
|
|
$ vi witness_node_data_dir/config.ini
|
|
p2p-endpoint = 0.0.0.0:9777
|
|
rpc-endpoint = 127.0.0.1:8090
|
|
seed-node = 213.184.225.234:59500
|
|
|
|
Start the witness back up
|
|
|
|
./programs/witness_node/witness_node
|
|
|
|
Upgrading A Peerplays Node
|
|
-----------------
|
|
To minimize downtime of your peerplays node when upgrading, one upgrade
|
|
idea was written in [this steemit
|
|
article](https://steemit.com/peerplays/@joseph/peerplays-update-setting-a-backup-witness-server-switching-servers).
|
|
|
|
Wallet Setup
|
|
-----------------
|
|
Then, in a separate terminal window, start the command-line wallet `cli_wallet`:
|
|
|
|
./programs/cli_wallet/cli_wallet
|
|
|
|
To set your initial password to 'password' use:
|
|
|
|
>>> set_password password
|
|
>>> unlock password
|
|
|
|
A list of CLI wallet commands is available
|
|
[here](https://github.com/PBSA/peerplays/blob/master/libraries/wallet/include/graphene/wallet/wallet.hpp).
|
|
|
|
|
|
Testnet - "Beatrice"
|
|
----------------------
|
|
- chain-id - T.B.D.
|
|
|
|
Use the `get_private_key_from_password` command
|
|
---------------------------------
|
|
You will to generate owner and active keys
|
|
|
|
```
|
|
get_private_key_from_password your_witness_username active the_key_you_received_from_the_faucet
|
|
```
|
|
This will reveal an array for your active key `["PPYxxx", "xxxx"]`
|
|
|
|
import_keys into your cli_wallet
|
|
-------------------------------
|
|
- use the second value in the array returned from the previous step for the private key
|
|
- be sure to wrap your username in quotes
|
|
- import the key with this command
|
|
```
|
|
import_key "your_witness_username" xxxx
|
|
```
|
|
|
|
Upgrade your account to lifetime membership
|
|
--------------------------------
|
|
```
|
|
upgrade_account your_witness_username true
|
|
```
|
|
|
|
Create your witness (substitute the url for your witness information)
|
|
-------------------------------
|
|
- place quotes around url
|
|
```
|
|
create_witness your_witness_username "url" true
|
|
```
|
|
**Be sure to take note of the block_signing_key**
|
|
|
|
IMPORTANT (issue below command using block_signing_key just obtained)
|
|
```
|
|
get_private_key block_signing_key
|
|
```
|
|
Compare this result to
|
|
|
|
```
|
|
dump_private_keys
|
|
```
|
|
You should see 3 pairs of keys. One of the pairs should match your block_signing_key and this is the one you will use in the next step!
|
|
|
|
Get your witness id
|
|
-----------------
|
|
```
|
|
get_witness username (note the "id" for your config)
|
|
```
|
|
|
|
Modify your witness_node config.ini to include **your** witness id and private key pair.
|
|
-------------------------
|
|
Comment out the existing private-key before adding yours
|
|
```
|
|
vim witness_node_data_dir/config.ini
|
|
|
|
witness-id = "1.6.x"
|
|
private-key = ["block_signing_key","private_key_for_your_block_signing_key"]
|
|
```
|
|
|
|
start your witness back up
|
|
------------------
|
|
```
|
|
./programs/witness_node/witness_node
|
|
```
|
|
|
|
If it fails to start, try with these flags (not for permanent use)
|
|
|
|
```
|
|
./programs/witness_node/witness_node --resync --replay
|
|
```
|
|
|
|
Vote for yourself
|
|
--------------
|
|
```
|
|
vote_for_witness your_witness_account your_witness_account true true
|
|
```
|
|
|
|
Ask to be voted in!
|
|
--------------
|
|
|
|
Join @Peerplays Telegram group to find information about the witness group.
|
|
http://t.me/@peerplayswitness
|
|
|
|
You will get logs that look like this:
|
|
|
|
```
|
|
2070264ms th_a application.cpp:506 handle_block ] Got block: #87913 time: 2017-05-27T16:34:30 latency: 264 ms from: bhuz-witness irreversible: 87903 (-10)
|
|
```
|
|
|
|
Assuming you've received votes, you will start producing as a witness at the next maintenance interval (once per hour). You can check your votes with.
|
|
|
|
```
|
|
get_witness your_witness_account
|
|
```
|
|
|
|
systemd
|
|
----------------
|
|
It's important for your witness to start when your system boots up. The filepaths here assume that you installed your witness into `/home/ubuntu/peerplays`
|
|
|
|
Create a logfile to hold your stdout/err logging
|
|
```bash
|
|
sudo touch /var/log/peerplays.log
|
|
```
|
|
|
|
Save this file in your peerplays directory. `vi /home/ubuntu/peerplays/start.sh`
|
|
```bash
|
|
#!/bin/bash
|
|
|
|
cd /home/ubuntu/peerplays
|
|
./programs/witness_node/witness_node &> /var/log/peerplays.log
|
|
```
|
|
Make it executable
|
|
```bash
|
|
chmod 744 /home/ubuntu/peerplays/start.sh
|
|
```
|
|
Create this file: `sudo vi /etc/systemd/system/peerplays.service`
|
|
Note the path for start.sh. Change it to match where your start.sh file is if necessary.
|
|
```

Enable the service

|
|
```
|
|
Make sure you don't get any errors
|
|
```bash
|
|
sudo systemctl status peerplays.service
|
|
```
|
|
Stop your witness if it is currently running from previous steps, then start it with the service.
|
|
```bash
|
|
sudo systemctl start peerplays.service
|
|
```
|
|
Check your logfile for entries
|
|
```bash
|
|
tail -f /var/log/peerplays.log
|
|
```
