vertica Database installation

Installing Vertica is fairly simple. With the following steps, we will try to understand a two-node cluster:
  1. Download the Vertica installation package from http://my.vertica.com/ according to the Linux OS that you are going to use.
  2. Now log in as root or use the sudo command.
  3. After downloading the installation package, install the package using the standard command:
    • For .rpm (CentOS/RedHat) packages, the command will be:
      rpm -Uvh vertica-x.x.x-x.x.rpm
      
    • For .deb (Ubuntu) packages, the command will be:
      dpkg -i vertica-x.x.x-x.x.deb
      
    Refer to the following screenshot for more details:

    Running the Vertica package
  4. In the previous step, we installed the package on only one machine. Note that Vertica is installed under /opt/vertica. Now, we will set up Vertica on other nodes as well. For that, run the following command on the same node:
    /opt/vertica/sbin/install_vertica -s host_list -r rpm_package -u dba_username
    
    Here, –s is the hostname/IP of all the nodes of the cluster, including the one on which Vertica is already installed. –r is the path of the Vertica package and –u is the username that we wish to create for working on Vertica. This user has sudo privileges. If prompted, provide a password for the new user. If we do not specify any username, then Vertica creates dbadmin as the user, as shown in the following example:
    [impetus@centos64a setups]$ sudo /opt/vertica/sbin/install_vertica -s 192.168.56.101,192.168.56.101,192.168.56.102 -r "/ilabs/setups/vertica-6.1.3-0.x86_64.RHEL5.rpm" -u dbadmin

    Check your NTP configuration for valid NTP servers.
    
    
    Vertica recommends that you keep the system clock synchronized using NTP or some other time synchronization mechanism to keep all hosts synchronized. Time variances can cause (inconsistent) query results when using Date/Time Functions. For instructions, see:

    CPU frequency scaling is enabled.  This may adversely affect the performance of your database.
    Vertica recommends that cpu frequency scaling be turned off or set to 'performance'

    To create a database:
    1. Logout and login as dbadmin.**
    2. Run /opt/vertica/bin/adminTools as dbadmin
    3. Select Create Database from the Configuration Menu
    
    ** The installation modified the group privileges for dbadmin.
       If you used sudo to install vertica as dbadmin, you will
       need to logout and login again before the privileges are applied.
    
  5. After we have installed Vertica on all the desired nodes, it is time to create a database. Log in as a new user (dbadmin in default scenarios) and connect to the admin panel. For that, we have to run the following command:
    /opt/vertica/bin/adminTools
    
  6. If you are connecting to admin tools for the first time, you will be prompted for a license key. If you have the license file, then enter its path; if you want to use the community edition, then just click on OK.

    License key prompt
  7. After the previous step, you will be asked to review and accept the End-user License Agreement (EULA).

    Prompt for EULA
    After reviewing and accepting the EULA, you will be presented with the main menu of the admin tools of Vertica.

    Admin tools main menu
  8. Now, to create a database, navigate to Administration Tools | Configuration Menu | Create Database.

    The Create Database option in the configuration menu
  9. Now, you will be asked to enter a database name and a comment that you would like to associate with the database.

    Database name and comments
  10. After entering the name and comment, you will be prompted to enter a password for this database.

    Password for the new database
  11. After entering and re-entering (for confirmation) the password, you need to provide pathnames where the files related to user data and catalog data will be stored.

    Catalog and data pathnames
    After providing all the necessary information related to the database, you will be asked to select hosts on which the database needs to be deployed. Once all the desired hosts are selected, Vertica will ask for one final check.

    Final confirmation for database creation
  12. Now, Vertica will create and deploy the database.

    Database creation
  13. Once the database is created, we can connect to it using the VSQL tool or perform admin tasks.
