1. Log in to your CentOS 7 VPS via SSH as user root
# ssh root@IP_Address
and update all installed services
# yum update
2. Run the ‘arch’ command in the terminal to check if your system is 32-bit (i686) or 64-bit (x86_64)
# arch
x86_64
3. In our case the system is 64-bit and we will download the 64-bit version of ionCube Loader
# wget http://downloads3.ioncube.com/loader_downloads/ioncube_loaders_lin_x86-64.tar.gz
4. If your system is 32-bit download the following archive
# wget http://downloads3.ioncube.com/loader_downloads/ioncube_loaders_lin_x86.tar.gz
