  1. Challenge

    Install Couchbase

    1. Get the Couchbase RPM for version 6 and install it:
    sudo yum install -y couchbase-server-community-6.0.0-centos7.x86_64.rpm 
    1. Set the file limits in the limits.conf file:
    sudo vim /etc/security/limits.conf

    Add these lines:

    * soft nofile 75000
    * hard nofile 75000
    1. Start the Couchbase server:
    sudo /opt/couchbase/bin/couchbase-server \-- -noinput -detached 
  2. Challenge

    Create the Bucket and Test Data

    1. From the GUI, simply add bucket.

    2. From the CLI

    couchbase-cli bucket-create -c --username Administrator --password Omgpassword! --bucket testdata --bucket-type couchbase --bucket-ramsize 128
    1. Connect to couchbase using cbq
       cbq -e -u=Administrator
    1. Locate the data in the ~/data folder. There is a formatted version and there is an unformatted version. Either way, create a query from this data and run it against the bucket.
    {"name":"Donald Duck",
    {"name":"Jimmy James",
    {"name":"Han Solo",
    {"name":"Chew Bacca",
  3. Challenge

    Confirm the Data Was Created Correctly

    1. In the GUI, the bucket will show the documents that were created, however, to make the bucket searchable, you will need to create an index:
    CREATE PRIMARY INDEX `td_idx` ON `testdata`;

    Then confirm that the data can be queried:

    Select * from `testdata`;
