Installing Moab HPC Suite - Basic Edition Suite RPM

This topic contains instructions on how to install TORQUE Resource Manager, Moab Workload Manager, and Moab Web Services installed on one server using the 8.1.0 suite RPM.

The RPM installation only supports installation on Red Hat 6.x, CentOS 6.x or Scientific Linux 6.x. Use the Manual installation instructions if installing on other supported operating systems.

Because many system-level files and directories are accessed during the installation, the instructions in this guide should be executed with root privileges.

You will see that the instructions execute commands as the root user. Please note that the same commands will work for a non-root user with the sudo command.

If you want to build a custom RPM for component documentation (Moab Workload Manager or Moab Web Services), see the Manual Installation Guide and follow instructions in the respective component.

Dependencies and Packages Installation

In this section:

Enable Extra Packages for the Repository

Many individual components have dependencies that are found in the optional add-on repositories for the distribution. You must enable the respective repository for your distribution on all hosts upon which you install Adaptive Computing software components.

Install Java

Install the Linux x64 RPM version of Oracle® Java® 7 Runtime Environment.

Oracle Java 7 Runtime Environment is the recommended Java environment, but Oracle Java 6 is also supported. All other versions of Java, including OpenJDK/IcedTea, GNU Compiler for Java, and so on cannot run Moab Web Services.

Do the following:

  1. Download the Linux x64 RPM version of Oracle Java SE 7 JRE. (Go to the Oracle Java 7 download page, copy the URL to the Linux x64 RPM version, then run the following command.)
    2. [root]# wget <URL> -O jre-7-linux-x64.rpm

    To verify that the download was successful, run the following on the RPM before installation:

    [root]# rpm -qip jre-7-linux-x64.rpm
  2. Run the following to install Java 7:
    3. [root]# rpm -Uh jre-7-linux-x64.rpm

Open Ports

A few ports need to be available through your firewall so components of the suite can communicate with each other. Some features of some components might need additional ports configured. The individual component documentation indicates when additional ports are needed.

To open ports in your firewall

Installing the Suite RPM

  1. If you are upgrading from a previous installation of Moab, back up your /opt/moab/tools directory to prevent losing modifications made to the perl scripts. If you are performing a clean installation of Moab HPC Suite, skip this step.
    2. [root]# tar czf backup-tools.tar.gz /opt/moab/tools
  2. Download the latest 8.1.0 RPM suite tarball (moab-hpc-basic-suite-<version>-<timestamp>-<OS>.tar.gz, for example) from the Adaptive Computing website.
  3. Untar the downloaded package.
    4. [root]# tar zxf moab-hpc-basic-suite-<version>-<timestamp>-<OS>.tar.gz
  4. Change directories into the untarred directory.

    Consider reviewing the README file for additional details on using the RPM distribution tarball.

  5. Install the suite repositories. The -y option installs with the default settings for the RPM suite.

    For a description of the options of the repository installer script, run:

    [root]# ./install-rpm-repos.sh -h

    [root]# ./install-rpm-repos.sh [<repository-directory>] [-y]

    If the installation returns the following warning line:

    Warning: RPMDB altered outside of yum.

    This is normal and can safely be ignored.

    6. The [<repository-directory>] option is the directory where you want to copy the RPMs. If no argument is given, run "install-rpm-repos.sh -h" and note the default directory location. If the [<repository-directory>] already exists, RPMs will be added to the existing directory. No files are overwritten in [<repository-directory>]. A repository file is also created in /etc/yum.repos.d/ and points to the [<repository-directory>] location.

    For ease in repository maintenance, the install script fails if Adaptive Computing RPMs are copied to different directories. If a non-default [<repository-directory>] is specified, please use the same directory for future updates.

    The script installs the createrepo package and its dependencies. You must answer "y" to all the questions in order for the RPM install of the suite to work. Additionally, the script installs the EPEL and 10gen repositories.

  6. Test the repository:
    7. [root]# yum search moab

    If no error is given, the repository is correctly installed. The output will look similar to the following (varying slightly depending on the suite and build type):

    ...

moab-hpc-basic-suite.noarch : Moab HPC Basic Suite virtual package
moab-perl-RRDs.noarch : Moab RRDs
moab-tomcat-config.x86_64 : Tomcat Configuration for Moab Viewpoint and Web Services

  7. Install the suite package. 
    [root]# yum install moab-hpc-basic-suite

    If you encounter the following error:

    ...
  --> Finished Dependency Resolution
krb5-workstation-1.6.1-62.el5.x86_64 from installed has depsolving problems
  --> Missing Dependency: krb5-libs = 1.6.1-62.el5 is needed by package krb5-workstation-1.6.1-62.el5.x86_64 (installed)

  --> Missing Dependency: krb5-libs = 1.6.1-62.el5 is needed by package krb5-workstation-1.6.1-62.el5.x86_64 (installed)
Error: Missing Dependency: krb5-libs = 1.6.1-62.el5 is needed by package krb5-workstation-1.6.1-62.el5.x86_64 (installed)
You could try using --skip-broken to work around the problem
You could try running: package-cleanup --problems
package-cleanup --dupes
rpm -Va --nofiles --nodigest

    Install the krb5-workstation package, then execute the install suite package again.

    [root]# yum install krb5-workstation
[root]# yum install moab-hpc-basic-suite

    If you encounter CURL library errors, make sure you are installing the correct version for your OS.

  8. Install and prepare the MongoDB database by doing the following:
    1. Install mongo-10gen-server.

      RHEL and CentOS, and Scientific Linux:

      [root]# yum install mongo-10gen-server
    1. Start MongoDB.
      2. [root]# chkconfig mongod on
[root]# service mongod start

[ OK ]
    2. Add the required MongoDB users.

      3. The passwords used below (secret1, secret2, and secret3) are examples. Choose your own passwords for these users.

      [root]# mongo
> use admin;
> db.addUser("admin_user", "secret1");
> db.auth("admin_user", "secret1");

> use moab;
> db.addUser("moab_user", "secret2");
> db.addUser("mws_user", "secret3", true);

> use mws;
> db.addUser("mws_user", "secret3");
> exit

      Because the admin_user has read and write permissions to the admin database, it also has read and write permissions to all other databases. See Control Access to MongoDB Instances with Authentication for more information.

    3. Enable authentication in MongoDB.

      4. RHEL and CentOS, and Scientific Linux:

      [root]# vi /etc/mongod.conf

auth = true
       
[root]# service mongod restart

Installing PostgreSQL

If you plan to use Moab Workload Manager with ODBC, you must install a PostgreSQL database.

To install PostgreSQL

  1. Install and initialize PostgreSQL.

    CentOS, RHEL, and Scientific Linux

    [root]# yum install postgresql-server

    [root]# service postgresql initdb

  2. Configure trusted connections.

    Modify the "host" lines in the pg_hba.conf file for the interfaces from which the server(s) (for example, Moab Workload Manager and/or Moab Accounting Manager) will be connecting to the database and ensure that it specifies a secure password-based authentication method (for example, md5).

    [root]# vi /var/lib/pgsql/data/pg_hba.conf
							
# IPv4 local connections:
host    all             all             127.0.0.1/32            md5
# IPv6 local connections:
host    all             all             ::1/128                 md5

    If the "host" lines are not present, add them as they appear above.

  3. Configure PostgreSQL to accept connections from your host.

    [root]# vi /var/lib/pgsql/data/postgresql.conf
     
    # Uncomment the listen addresses line in the configuration:

listen_addresses = 'localhost'          # what IP address(es) to listen on;

  4. Start or restart the database.

    [root]# chkconfig postgresql on
    [root]# service postgresql restart
