Tested and working on Ubtunu 14 - 16.04 and 17. Version 16.04 is recommended. Versions 18.04 and later do not currently compile due to changes in OpenSSL 1.1 and the Boost C++ library in that version.
You can check if your server has a swap file already with the swapon command. If your system has less than 1.5GB of memory, you'll want at least a 2GB swap area. Add a new swapfile with:
sudo fallocate -l 2G /swapfile
sudo chown root:root /swapfile
sudo chmod 0600 /swapfile
sudo bash -c "echo 'vm.swappiness = 10' >> /etc/sysctl.conf"
sudo mkswap /swapfile
sudo swapon /swapfile
If fallocate doesn’t work, you can instead use:
sudo dd if=/dev/zero of=/swapfile bs=1024 count=1024288
Initialize the swapfile to mount automatically on boot:
sudo echo '/swapfile none swap sw 0 0' >> /etc/fstab
sudo apt-get -y install nano ntp unzip git build-essential libssl-dev \
libdb-dev libdb++-dev libboost-all-dev libqrencode-dev aptitude
sudo aptitude -y install miniupnpc libminiupnpc-dev
If you get an error mentioning lock files, you probably have a desktop or background package update tool running that prevents other apt changes from happening. You can use the lsof utility to figure out what program holds the lock and then pause it from running.
Pull the source code from github, or download it yourself:
git clone https://github.com/2X2coin/2x2coin.git
Now you compile the included leveldb:
cd 2x2coin/src/leveldb
chmod +x build_detect_platform
make clean
make libleveldb.a libmemenv.a
Return to the source directory, and compile the daemon:
cd ..
make -f makefile.unix
Strip the file to make it smaller, then relocate it:
strip 2X2d
sudo cp 2X2d /usr/bin
Now run the daemon:
X2d
It should return an error, telling you to set up config file in a directory.
Now we’ll set up the config file. Note that this is case sensitive.
nano ~/.2X2/2X2.conf
Add the following, save and exit:
daemon=1
server=1
rpcuser=(username)
rpcpassword=(strong password)
Run 2X2d once more and if you did everything correctly, your daemon is now online!
