Installing Moab HPC Suite - Edition

Dependencies and packages installation

Install Java

You must install the 64-bit RPM version of Oracle® Java® 7 Runtime Environment if you are installing Moab Web Services.

Do the following:

1. Download Java 7 on a web-enabled workstation.
   1. Open a web browser and connect to the Java downloads page.
   2. Select the radio button to accept the license agreement.
   3. Click the download link for the Linux x64 RPM file.
2. Copy the Java 7 RPM to the MWS server using scp, rsync, or any similar network copy utility.
3. On the MWS server, run the following to install Java 7:

   [root]# rpm -Uh <RPMfilename>

Opening 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.

• 8080: Needed for Moab Web Services web portal (http)

To open ports in your firewall

• Use iptables for Red Hat-based distributions:

[[root]# iptables-save > /tmp/iptables.mod

[root]# vi /tmp/iptables.mod

# Add the following lines immediately *before* the line matching

# "-A INPUT -j REJECT --reject-with icmp-host-prohibited"

-A INPUT -p tcp --dport 8080 -j ACCEPT

[root]# iptables-restore < /tmp/iptables.mod

[root]# service iptables save

• Use SuSEfirewall2 for SuSE-based distributions:

[root]# vi /etc/sysconfig/SuSEfirewall2

FW_SERVICES_EXT_TCP="8080"

[root]# service SuSEfirewall2_setup restart

Installing the RPM suite

To install the RPM suite

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.

[root]# tar czf backup-tools.tar.gz /opt/moab/tools

2. Download the latest 8.0.3 RPM suite tarball (moab-hpc--suite-<version>-<timestamp>-<OS>.tar.gz, for example) from the Adaptive Computing website.
3. Untar the downloaded package.

[root]# tar zxf moab-hpc--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.

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:

[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--suite.noarch : Moab HPC  Suite virtual package
moab-perl-RRDs.noarch : Moab RRDs
moab-tomcat-config.x86_64 : Tomcat Configuration for Moab Viewpoint and Web Services
moab-verify-oracle-java.noarch : Java Validator for Moab Viewpoint and Web Services
moab-web-services.x86_64 : Moab Web Services
moab-workload-manager.x86_64 : Moab Workload Manager
moab-workload-manager-client.x86_64 : Moab Workload Manager Client
moab-workload-manager-common.x86_64 : Moab Workload Manager Common Files
moab-perl-data.noarch : Perl Configuration for perl packages by Adaptive Computing
moab-torque-client.x86_64 : TORQUE Client
moab-torque-common.x86_64 : TORQUE Common Files
moab-torque-devel.x86_64 : TORQUE Development Files
moab-torque-mom.x86_64 : TORQUE MOM agent
moab-torque-server.x86_64 : TORQUE Server
moab-web-services-hpc-configuration.x86_64 : MWS configuration for HPC
moab-workload-manager-hpc-configuration.x86_64 : MWM configuration for HPC

7. Install the suite package.

   [root]# yum install moab-hpc--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)
   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)
   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--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.

   [root]# yum install mongo-10gen-server --exclude mongodb-org,mongodb-org-server

   

   Running yum upgrade will replace MongoDB 2.4.x with a more recent, and incompatible version. Consider using yum version lock to maintain MongoDB 2.4.x.

   2. Start MongoDB.

   RHEL and CentOS, and Scientific Linux:

   [root]# chkconfig mongod on
   [root]# service mongod start
   
   [ OK ]

   3. Add the required MongoDB users.
   

   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.

   4. Enable authentication in MongoDB.

   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

   SLES

   [root]# zypper install postgresql-server

   [root]# service postgresql start

2. Configure trusted connections.

   

   Edit or add a "host" line in the pg_hba.conf file for the interface 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

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
