MetaHash network Proxy

This repository contains the Proxy Node source code written in C++. There are two internal libraries: libmicrohttpd2 and libmhsupport used in this code.

Pre-built binary for ubuntu 14/16/18 available here: releases.

Requirements

cmake > 3.8
gcc > 8.0
libevent 2.1.8

Build

Please follow these steps to build and run Proxy on Ubuntu 14.04 x64:

1. Preparation

sudo add-apt-repository ppa:ubuntu-toolchain-r/test
sudo apt update

sudo apt install gcc-8 g++-8 liburiparser-dev libssl-dev libevent-dev git automake libtool texinfo make
    
sudo update-alternatives --install /usr/bin/gcc gcc /usr/bin/gcc-8 60 --slave /usr/bin/g++ g++ /usr/bin/g++-8
sudo update-alternatives --config gcc

2. Get and compile latest cmake

cd /tmp
wget https://github.com/Kitware/CMake/releases/download/v3.13.0/cmake-3.13.0.tar.gz
tar zxfv cmake-3.13.0.tar.gz
cd cmake-3.13.0
./bootstrap
./configure
make
sudo make install 

3. Get and compile libevent

cd /tmp
wget https://github.com/libevent/libevent/releases/download/release-2.1.8-stable/libevent-2.1.8-stable.tar.gz
tar zxfv libevent-2.1.8-stable.tar.gz
cd libevent-2.1.8-stable
./configure
make
sudo make install

4. Get and compile libmicrohttpd2

Please note: you must use this libmicrohttpd2 library, because the original libmicrohttpd library has no all functions available which are necessary for running Proxy.

cd /tmp
git clone https://github.com/metahashorg/libmicrohttpd2
cd libmicrohttpd2
./bootstrap
./configure
make
sudo make install

5. Get and compile libmhsupport

cd /tmp
git clone https://github.com/metahashorg/libmhsupport
cd libmhsupport/build
./build.sh
sudo make install

6. Build Proxy Node

cd /tmp
git clone https://github.com/metahashorg/node_proxy
cd node_proxy/build
./build.sh

Update proxy to recent version

1. Stop running proxy:

kill `ps axuwf|grep proxy_config|grep -v grep|awk '{print $2}'`

2. Go to directory where you've cloned node_proxy, for example

cd /tmp/node_proxy

git pull
cd build
rm -rf
cmake ..
make -j

3. Start proxy:

./proxy proxy_key proxy_config 9999 1000000

Script for starting, stopping, restarting.

Script proxy.sh for the following operations with Metahash proxy application:

• starting,
• stopping,
• restarting,
• getting status.

Note: default workdir is /opt/proxy. If you’ve install proxy to another location please change workdir in script.

Usage script

RUN script as follows:

./proxy.sh status
