README.Linux.md

For CentOS:

• Install Dependencies

  ./README.CentOS.bash

• If you want to link cmake3 to cmake, run:

  sudo ln -sf /usr/bin/cmake3 /usr/local/bin/cmake

• Make sure that you add /usr/local/lib and /usr/local/lib64 to /etc/ld.so.conf, then run command ldconfig.

• If you want to install and use gcc-7 by default, run:

  sudo yum install -y centos-release-scl
  sudo yum install -y devtoolset-7-toolchain
  echo 'source scl_source enable devtoolset-7' >> ~/.bashrc

For RHEL:

• Install Development Tools.

  • For RHEL 8: Install Development Tools:

    sudo yum group install -y "Development Tools"

  • For RHEL versions (< 8.0): Install devtoolset-7:

    sudo yum-config-manager --enable rhui-REGION-rhel-server-rhscl
    sudo yum install -y devtoolset-7-toolchain

• Install dependencies using README.CentOS.bash script.

  • For RHEL 8: Execute additional step before running README.CentOS.bash script.

    Note: Make sure installation of Development Tools includes git and make else install these tools manually.

    sudo yum install -y https://dl.fedoraproject.org/pub/epel/epel-release-latest-8.noarch.rpm

  • Install dependencies using README.CentOS.bash script.

    ./README.CentOS.bash

For Ubuntu:

• Install Dependencies When you run the README.Ubuntu.bash script for dependencies, you will be asked to configure realm for kerberos. You can enter any realm, since this is just for testing, and during testing, it will reconfigure a local server/client. If you want to skip this manual configuration, use: export DEBIAN_FRONTEND=noninteractive

  sudo ./README.Ubuntu.bash

• Ubuntu 18.04 and newer should have use gcc 7 or newer, but you can also enable gcc-7 on older versions of Ubuntu:

  sudo add-apt-repository ppa:ubuntu-toolchain-r/test -y
  sudo apt-get update
  sudo apt-get install -y gcc-7 g++-7

Common Platform Tasks:

Make sure that you add /usr/local/lib to /etc/ld.so.conf, then run command ldconfig.

1. Create gpadmin and setup ssh keys Either use:

   # Requires gpdb clone to be named gpdb_src
   gpdb_src/concourse/scripts/setup_gpadmin_user.bash

   to create the gpadmin user and set up keys,

   OR

   manually create ssh keys so you can do ssh localhost without a password, e.g.,

   ssh-keygen
   cat ~/.ssh/id_rsa.pub >> ~/.ssh/authorized_keys
   chmod 600 ~/.ssh/authorized_keys
   

2. Verify that you can ssh to your machine name without a password.

   ssh <hostname of your machine>  # e.g., ssh briarwood (You can use `hostname` to get the hostname of your machine.)

3. Set up your system configuration by following the installation guide on docs.greenplum.org
