Masternode setup guide for Social SEND on a remote VPS

This is a guide to show you how to setup a remote masternode for Social SEND on a linux based VPS (Virtual Private Server).

Prerequisites:

• A linux based VPS with at least 512 MB of RAM, 5 GB of free space. For this guide we will use a cheap Vultr VPS with Ubuntu Linux 14.04 preinstalled. (Will also work with Ubuntu 16.04, 18.04 hasn't been tested yet).
 
• A ssh client to log into your VPS (I'm using PuTTY).
• A fully synced, local Social SEND wallet with at least 12.500 spendable coins in it.

Step 1. - Prepare your local Wallet

---

Step 1.1 - Open your local SEND wallet and go to: "Tools > Debug console" and enter the following command: "masternode genkey". 

 

The output should look something like this: 

 

Save this information into a seperate File called "SEND-MN-Setup-Info.txt".

---

Step 1.2 - Within you local SEND wallet create a new receiving address for your masternode. 

To do so go to: "Receive", enter a name for your MN-addres into the inputbox called "Label", e.g. "Masternode1" (without the ") and click on "Request payment". 

 

Your new receiving address should now be visible within the "Requested payments history" box. Double click on your new address and copy it.

---

Step 1.3 - Now send exactly 12.500 SEND to your newly created MN-receiving address and wait for at least 15 confirmations. 

 

Afterwards head over to "Tools > Debug console" again and enter the following command: "masternode outputs". The output should look similar to this: 

 

Save the output to your "SEND-MN-Setup-Info.txt" (we will need it later on).

---

Step 2. - Prepare your VPS

---

Step 2.1 - Get your VPS up to date

Log into your VPS via SSH.

sudo apt-get update

sudo apt-get upgrade -y

sudo apt-get autoremove -y

---

Step 2.2 - Create a new send user

sudo adduser send (set the UNIX password for the send user, additional information like name etc. is optinal)

sudo adduser send sudo 

---

Step 2.3 - (Optional, but recommended) - Configure the firewall

sudo ufw default deny incoming 

sudo ufw default allow outgoing 

sudo ufw allow ssh/tcp 

sudo ufw limit ssh/tcp 

sudo ufw allow 50050/tcp 

sudo ufw logging on 

sudo ufw --force enable 

sudo reboot 

---

Step 2.4 - (Optional, but recommended) - Additional security through fail2ban

sudo apt-get install fail2ban -y 

---

Step 2.5 - (Optional, but recommended) - Permit root login

sudo nano /etc/ssh/sshd_config 

Search for the line: "PermitRootLogin yes" or "PermitRootLogin without-password" and change it to "PermitRootLogin no" (CTRL+X, Y, Enter to save your changes).

After you have saved your changes restart the ssh daemon with: "sudo service ssh restart".

---

Step 2.6 - Set up swap space (as root user)

sudo su 

fallocate -l 3G /swapfile 

chmod 600 /swapfile 

mkswap /swapfile 

swapon /swapfile 

echo -e "/swapfile none swap sw 0 0 \n" >> /etc/fstab 

---

Step 2.7 - Install dependencies (as send user)

su send 

sudo apt-get install pkg-config build-essential autoconf automake libtool libboost-all-dev libgmp-dev libssl-dev libcurl4-openssl-dev git software-properties-common unzip -y

 

sudo add-apt-repository ppa:bitcoin/bitcoin 

sudo apt-get update 

sudo apt-get install libdb4.8-dev libdb4.8++-dev -y 

---

Step 3. - Install the Social SEND daemon and client to your VPS

---

Step 3.1 - Clone the Social SEND github repo

cd 

sudo git clone https://github.com/SocialSend/SocialSend.git 

---

Step 3.2 - Make the installation scripts executable

cd SocialSend 

sudo chmod +x share/genbuild.sh 

sudo chmod +x autogen.sh 

sudo chmod 755 src/leveldb/build_detect_platform 

---

Step 3.3 - Preconfigure the Social SEND installation

sudo ./autogen.sh 

sudo ./configure 

---

Step 3.4 - Install the Social SEND daemon and client

sudo make 

sudo make install 

---

Step 3.5 - Make the SEND daemon and client globally accessible on your VPS

cd 

sudo cp ./SocialSend/src/sendd /bin 

sudo cp ./SocialSend/src/send-cli /bin 

---

Step 3.6 - Test the SEND daemon and client

sendd -daemon -txindex 

send-cli getinfo (The first time you run this code you might get an error saying: "error: {"code":-28,"message":"Loading wallet... (50.25 %)"}" -> This only means that your wallet hasn't been loaded yet. Give it a few more seconds and rerun the command.

---

Step 3.7 - Get the Socials SEND wallet to sync and install the latest bootstrap

send-cli stop 

cd 

Now get the downloadlink for the latest bootstrap from SocialSend.io or from me (Voxcon) in our Discord channel. The current download command is (09/07/2018):

wget --header 'Host: uc1b76f399101a682ceadacf263b.dl.dropboxusercontent.com' --header 'Accept: text/html,application/xhtml+xml,application/xml;q=0.9,*/*;q=0.8' --referer 'https://www.dropbox.com/' --header 'Upgrade-Insecure-Requests: 1' 'https://uc1b76f399101a682ceadacf263b.dl.dropboxusercontent.com/cd/0/get/AP0vP5iaQICppBf2uNCXGlD9n5Okm9e62I69Dm_Aws3c9lbto1HcLPfFfqA3573fNvtt9R5QSoV4Rc3iY-_TPodQnyo3wOtpRawXJoYmB9VTW8qhIP7DCrHod7U4-HIEJ8nnUXcrKgzZN6rrf_pXeKrDK0cWd_B-dViQnOM-dvLXZ4IS_jUiMAHv54lvPL45Vxk/file?_download_id=86035074198974732975068810561815808133861356315339787518060399774&_notify_domain=www.dropbox.com&dl=1' --output-document 'bootstrap.zip'

 

unzip ./bootstrap.zip -d ./bootstrap 

sudo rm -rf ~/.send/blocks 

sudo rm -rf ~/.send/chainstate 

sudo rm ~/.send/peers.dat (Don't worry if you get an error saying: "No such file or directory". This only means the file does not yet exist)

sudo cp ./bootstrap/blocks ~/.send 

sudo cp ./bootstrap/chainstate ~/.send 

sudo cp ./bootstrap/peers.dat ~/.send 

sendd -daemon -txindex 

watch send-cli getinfo (Have a look at the blockheight and compare it to the blockheight of your local wallet or our block explorer and let your VPS daemon sync. Use CTRL+C to stop watching)

 

---

Step 4. - Configure SEND on your VPS

---

Step 4.1 - Configure SEND on your VPS

send-cli stop 

sudo nano ~/.send/send.conf 

---

Step 4.2 - Post the following lines into your send.conf and adjust them to fit your settings  (CTRL+X, Y, Enter to save your changes)

rpsuser=CHOOSE-ANY-RPCUSERNAME-YOU-WANT-EXCEPT-"send"
rpcpassword=CHOOSE-ANY-PASSWORD-YOU-WANT
rpcallowip=127.0.0.1
listen=1
server=1
staking=1
daemon=1
logtimestamps=1
maxconnections=256
masternode=1
masternodeprivkey=THE-OUTPUT-OF-MASTERNODE-GENKEY-FROM-STEP-1.1-GOES-HERE
externalip=YOUR-VPS-IP-GOES-HERE

---

Step 4.3 - Restart the SEND daemon

sendd -daemon -txindex 

watch send-cli getinfo (Let the daemon sync and close the watch command with CTRL+C)

---

Step 5. - Configure your local wallet

---

Step 5.1 - Configure the masternodes.conf on your local machine

Open your local wallet and go to: "Tools > Open Masternode Cofiguration File" and enter the following line at the bottom of the file and adjust the values according to your settings:

Masternode1 YOUR-VPS-IP-GOES-HERE:50050 OUTPUT-OF-MASTERNODE-GENKEY-GOES-HERE-FROM-STEP-1.1 TXHASH-FROM-MASTERNODE-OUTPUTS-GOES-HERE-FROM-STEP-1.3 OUTPUTINDEX-FROM-MASTERNODE-OUTPUTS-GOES-HERE-FROM-STEP-1.3

 

When you have adjusted your values correctly, the last line of your masternode configuration file should look something like this:

Masternode1 45.32.155.138:50050 88ZXmAF8is6XnfD6z7LnCZrHxishnnzzyuSeYQz4KYib9AvjmMT 7337a48d396798cf61a124eed5c619a29a998ba533650839edb2bd7fdbbd42e9 0

---

Step 5.3 - Configure the send.conf on your local machine

Open your local wallet and go to: "Tools > Open Wallet Cofiguration File" and enter your rpcusername and rpcpassword form step 4.2 as follows:

rpsuser=THE-RPCUSER-YOU-HAVE-ENTERED-IN-STEP-4.2
rpcpassword=THE-RPCPASSWORD-YOU-HAVE-ENTERED-IN-STEP-4.2

 

Save the changes and close your local wallet. 

---

Step 5.4 - Sart Alias

Reopen your local wallet and enable your masternode within the "Masternodes" tab by clicking on "Start alias".

 

You should see the following message:

 

---

Step 6. - Check if your masternde is running correctly

---

Step 6.1 -VPS check

Switch to your VPS and execute the following command: send-cli getmasternodestatus

 

---

Step 7. (Optional) - Automatically restart the SEND daemon when your VPS restarts

---

Step 7.1 - SSH into your VPS as user "send" or change your current user to "send" with the command "su send"

---

Step 7.2 - Add a cronjob to the bootprocedure of your VPS

crontab -e (choose nano as the editor to open the crontab file)

Add the following line to the bottom of your crontab file:

@reboot sleep 15; sendd -daemon -txindex (CTRL+X, Y, Enter to save your changes)

---

Awesome, now you have successfully setup your Social SEND masternode :-) 

If you have run into any problems, please let me know and i'll try to help you.

With best regards,

PS: A simple masternode setup script is already in the making, but it needs a little more tweaking here and there. Please be a bit patient.
