8.1. Installing Presto Admin

Currently presto-admin is supported on following platforms:
  • Red Hat Enterprise Linux (RHEL) 6.x
  • Red Hat Enterprise Linux (RHEL) 7.x
  • CentOS equivalent to RHEL (Community ENTerprise Operating System)
  • Oracle Linux 7
  • SUSE Linux Enterprise Server (SLES) SP4 11
  • SUSE Linux Enterprise Server (SLES) SP3 12

Presto Admin is packaged as an offline installer – prestoadmin-<version>-offline.tar.gz – and as an online installer – prestoadmin-<version>-online.tar.gz.

The offline installer includes most of the dependencies for presto-admin, so it can be used on a cluster with limited Internet connectivity. For the supported systems the supported way of installing presto-admin is though offline installer.

Prerequisites list for offline presto-admin installer per platform
  • Red Hat Enterprise Linux 6/CentOS 6
    • Python 2.6.
    • tar
    • libffi
    • openssl
    • openssh
    • openssh-clients
    • openssh-server
    • sudo (when presto-admin connects as non-root user via SSH)
  • Red Hat Enterprise Linux 7/Oracle Linux 7
    • Python 2.7.
    • tar
    • libffi
    • openssl
    • openssh
    • openssh-clients
    • openssh-server
    • net-tools
    • sudo (when presto-admin connects as non-root user via SSH)
  • SUSE Linux Enterprise Server SP4 11
    • Python 2.6.
    • tar
    • libffi43
    • openssh
    • gawk
    • aaa_base
    • glibc-locale
    • glibc-i18ndata
    • python-xml
    • sudo (when presto-admin connects as non-root user via SSH)
  • SUSE Linux Enterprise Server SP3 12
    • Python 2.7.
    • tar
    • libffi4
    • openssh
    • aaa_base
    • glibc-locale
    • glibc-i18ndata
    • python-xml
    • sudo (when presto-admin connects as non-root user via SSH)

Note: depending on particular installation some of those requirements could already have been satisfied.

The online installer downloads the dependencies when you run ./install-prestoadmin.sh. You must use the online installer for installation of Presto on Amazon EMR and for use on any operating system not listed above. If you are using presto-admin on an unsupported operating system, there may be operating system dependencies beyond the installation process, and presto-admin may not work.

To install presto-admin:

1. Copy the installer prestoadmin-<version>-offline.tar.gz to the location where you want presto-admin to run. Note that presto-admin does not have to be on the same node(s) where Presto will run, though it does need to have SSH access to all of the nodes in the cluster.

Note

For Amazon EMR, use the online installer instead of the offline installer.

2. Extract and run the installation script from within the prestoadmin directory.

$ tar xvf prestoadmin-<version>-offline.tar.gz
$ cd prestoadmin
$ ./install-prestoadmin.sh

The installation script will create a presto-admin-install directory and an executable presto-admin script. By default, the presto-admin config and log directory locations are configured to be ~/.prestoadmin and ~/.prestoadmin/log, respectively. This can be changed by modifying the environment variables, PRESTO_ADMIN_CONFIG_DIR and PRESTO_ADMIN_LOG_DIR. The installation script will also create the directories pointed to by PRESTO_ADMIN_CONFIG_DIR and PRESTO_ADMIN_LOG_DIR. If those directories already exist, the installation script will not erase their contents.

3. Verify that presto-admin was installed properly by running the following command:

$ ./presto-admin --help

Please note that you should only run one presto-admin command on your cluster at a time.
