Centos 7.7

This section contains shell commands to manually download, build, install, test, and uninstall EOSIO and dependencies on Centos 7.7.

[[info | Building EOSIO is for Advanced Developers]] | If you are new to EOSIO, it is recommended that you install the EOSIO Prebuilt Binaries instead of building from source.

Select a task below, then copy/paste the shell commands to a Unix terminal to execute:

[[info | Building EOSIO on another OS?]] | Visit the Build EOSIO from Source section.

Download EOSIO Repository

These commands set the EOSIO directories, install git, and clone the EOSIO repository.

# set EOSIO directories
export EOSIO_LOCATION=~/eosio/eos
export EOSIO_INSTALL_LOCATION=$EOSIO_LOCATION/../install
mkdir -p $EOSIO_INSTALL_LOCATION
# install git
yum update -y && yum install -y git
# clone EOSIO repository
git clone https://github.com/EOSIO/eos.git $EOSIO_LOCATION
cd $EOSIO_LOCATION && git submodule update --init --recursive

Install EOSIO Dependencies

These commands install the EOSIO software dependencies. Make sure to Download the EOSIO Repository first and set the EOSIO directories.
