[Guide] Create a full node and Build Feathercoin v0.16 on Centos 7.

AcidD

Hi All,

If you’d like to help the network, get yourself a little Centos7 VPS and create a full node! :-)

The following assumes a new Centos 7 Minimal Installation, and you’ve just logged in as root for the first time.

Upgrade OS Repositories

yum upgrade -y

Add EPEL Repositories

yum install -y epel-release

Install Feathercoin dependencies

yum -y install gcc-c++ libtool make autoconf automake openssl-devel libevent-devel boost-devel libdb4-devel libdb4-cxx-devel which git bzip2 wget

Since Centos 7 comes with a version of OpenSSL that has ECC disabled, we need to build a new version of OpenSSL with ECC enabled. Otherwise FTC wont run and will give you an ssl error on compile

Download, Extract and Build OpenSSL with ECC enabled.

cd /usr/src
wget https://www.openssl.org/source/openssl-1.0.2k.tar.gz
tar zxvf openssl-1.0.2k.tar.gz
cd openssl-1.0.2k
export CFLAGS="-fPIC"
./config --prefix=/opt/openssl shared enable-ec enable-ecdh enable-ecdsa
make all -j2
sudo make install -j2

Download, Extract and Build Feathercoin .

cd /usr/src
git clone https://github.com/FeatherCoin/Feathercoin.git FTC
cd FTC
./autogen.sh
./configure  --disable-shared --without-gui --prefix=/opt/feathercoin PKG_CONFIG_PATH=/opt/openssl/lib/pkgconfig LIBS=-Wl,-rpath,/opt/openssl/lib
make
sudo make install

If you try to run feathercoind now, it will complain about not having a conf file, so we need to create one.
.
.
.

Create blank feathercoin.conf

touch /root/.feathercoin/feathercoin.conf

Edit the conf file

vi /root/.feathercoin/feathercoin.conf

Add an rpc user and a complex password like in the example below.

rpcuser=feathercoinrpc
rpcpassword=HyeZz7WZJwCvYrThisISaComplexPassword7dX7ej1zbTV6s3

.

Open up port 9336 so feathercoin can accept connections and help the network

in Centos 7, we now have the awesome firewall-cmd client. which interacts with firewalld

Add port 9336

sudo firewall-cmd --zone=public --add-port=9336/tcp --permanent

Reload load the firewall rules after adding the feathercoin port.

sudo firewall-cmd --reload

You can check your open port with this command.

sudo firewall-cmd --list-all

You should see something like this.

public (default, active)
  interfaces: eth0
  sources:
  services: dhcpv6-client ssh
  ports: 9336/tcp
  masquerade: no
  forward-ports:
  icmp-blocks:
  rich rules:

.

You can now start feathercoind to start your node

cd /opt/feathercoin/bin

./feathercoind --server &

You can check on the status of your node with this command

./feathercoin-cli getnetworkinfo

And you should see something like this:

{
  "version": 160000,
  "subversion": "/Feathercoin:0.16.0/",
  "protocolversion": 70015,
  "localservices": "0000000000000409",
  "localrelay": true,
  "timeoffset": 3,
  "networkactive": true,
  "connections": 8,
  "networks": [
    {
      "name": "ipv4",
      "limited": false,
      "reachable": true,
      "proxy": "",
      "proxy_randomize_credentials": false
    },
    {
      "name": "ipv6",
      "limited": false,
      "reachable": true,
      "proxy": "",
      "proxy_randomize_credentials": false
    },
    {
      "name": "onion",
      "limited": true,
      "reachable": false,
      "proxy": "",
      "proxy_randomize_credentials": false
    }
  ],
  "relayfee": 0.00100000,
  "incrementalfee": 0.00001000,
  "localaddresses": [
    {
      "address": "90.252.127.106",
      "port": 9336,
      "score": 3
    }
  ],
  "warnings": ""
}

.

Make feathercoind start on system reboot by creating it as a service

Create the feathercoin service file

touch /etc/systemd/system/feathercoind.service

Edit the file

vi /etc/systemd/system/feathercoind.service

Add this to the file

[Unit]
Description=Feathercoinss distributed currency daemon
After=network.target

[Service]
User=root
Group=root

Type=forking
PIDFile=/root/.feathercoin/feathercoind.pid
ExecStart=/opt/feathercoin/bin/feathercoind -daemon -pid=/root/.feathercoin/feathercoind.pid \
-conf=/root/.feathercoin/feathercoin.conf -datadir=/root/.feathercoin

Restart=always
PrivateTmp=true
TimeoutStopSec=60s
TimeoutStartSec=2s
StartLimitInterval=120s
StartLimitBurst=5

[Install]
WantedBy=multi-user.target

You can now start feathercoind with:

sudo systemctl start feathercoind

Youc an stop feathercoind with this:

sudo systemctl stop feathercoind

And you can check the status with this:

sudo systemctl status feathercoind

Finally, to configure the service to start at boot

sudo systemctl enable feathercoind

Edit 09/05/2018: Updated for version 0.16
Edit: Updated for version v0.9.6

I hope this helps someone. :-)

I’ve been running various wallets and patches on Centos 7 for quite a while now and this is a great example that can be applied to many many coins.

Thanks for the detailed step by step, this will simplify many wallet upgrades for me!

THANKS!

Back to mining FTC…

Cool, We do need more nodes.

AcidD

Oh, The last step would be to make sure you’ve opened the port on your router (port forwarding)

It’s nice to see this guide more or less copy and pasted ;-) here:

Updated for 0.16 if anyone is interested.

Nice! :))

Looking forward to see majority of the network running on 0.16 soon
