Build & Run an iBitHub Full Node

Step 0 — VPS Setup

Use Ubuntu 18.04 LTS VPS (2–4 vCPU, 4–8GB RAM, 50+ GB SSD). Recommended providers: Vultr, Hetzner, OVH, DigitalOcean, Linode.

Option 1 — Native Ubuntu 18.04 Build

1. Update system

   sudo apt updateCopy

2. Install dependencies

   sudo apt install -y build-essential git libboost-all-dev libminiupnpc-dev libevent-devCopy

   sudo apt install -y automake autotools-dev pkg-configCopy

3. Build Berkeley DB 4.8

   cd ~Copy

   wget http://download.oracle.com/berkeley-db/db-4.8.30.NC.tar.gzCopy

   tar -xzf db-4.8.30.NC.tar.gzCopy

   cd db-4.8.30.NC/build_unixCopy

   ../dist/configure --enable-cxx --disable-shared --with-picCopy

   make -j$(nproc)Copy

   sudo make installCopy

   → Installs to /usr/local/BerkeleyDB.4.8

4. Build OpenSSL 1.0.2u

   cd ~Copy

   wget https://www.openssl.org/source/old/1.0.2/openssl-1.0.2u.tar.gzCopy

   tar -xzf openssl-1.0.2u.tar.gzCopy

   cd openssl-1.0.2uCopy

   ./config --prefix=/usr/local/openssl-1.0.2 no-shared no-threads -fPICCopy

   make -j$(nproc)Copy

   sudo make installCopy

   → Installs to /usr/local/openssl-1.0.2

5. Clone repository

   cd ~Copy

   git clone https://github.com/ibithub/ibithub.gitCopy

   cd ibithub/srcCopy

6. Step 6 — Update makefile.unix

   In makefile.unix Find:

   bitcoind: $(OBJS:obj/%)
   $(LINK) $(xCXXFLAGS) -o $@ $^ $(xLDFLAGS) $(LIBS)
   

   Add above it:

   ibithub-cli: $(OBJS:obj/%)
   	$(LINK) $(xCXXFLAGS) -o $@ $^ $(xLDFLAGS) $(LIBS)Copy

   Also add at the top of makefile.unix:

   BDB_PREFIX = /usr/local/BerkeleyDB.4.8
   OPENSSL_PREFIX = /usr/local/openssl-1.0.2
   
   CXXFLAGS += -I$(BDB_PREFIX)/include -I$(OPENSSL_PREFIX)/include \
               -Wno-deprecated-declarations -Wno-error
   LDFLAGS  += -L$(BDB_PREFIX)/lib -L$(OPENSSL_PREFIX)/lib
   LIBS     += -ldb_cxx -lssl -lcrypto -lboost_system -lboost_filesystem -lboost_program_options -lboost_threadCopy

7. Build binaries

   make -f makefile.unix cleanCopy

   make -f makefile.unix -j$(nproc)Copy

   → Produces ibithubd and ibithub-cli

8. Run iBitHub

   export LD_LIBRARY_PATH=/usr/local/openssl-1.0.2/lib:$LD_LIBRARY_PATHCopy

   ./ibithubd -daemonCopy

   Create minimal ~/.ibithub/ibithub.conf:

   rpcuser=youruser
   rpcpassword=yourpassCopy

Option 2 — Docker Container Build

1. Install Docker on host

   sudo apt updateCopy

   sudo apt install -y docker.ioCopy

   sudo systemctl enable --now dockerCopy

   sudo usermod -aG docker $USERCopy

   newgrp dockerCopy

2. Start Ubuntu 18.04 container

   docker run -it --name ibithub-build ubuntu:18.04 /bin/bashCopy

3. Inside container — install dependencies & repeat Option 1 steps

   apt updateCopy

   apt install -y build-essential git libboost-all-dev libminiupnpc-dev libevent-dev wget automake autotools-dev pkg-configCopy

   Then repeat steps 3–7 from Option 1 inside container.

4. Copy binaries to host

   docker cp ibithub-build:/root/ibithub/src/ibithubd .Copy

   docker cp ibithub-build:/root/ibithub/src/ibithub-cli .Copy
