Install Couchbase

Get the Couchbase RPM for version 6 and install it:

wget https://packages.couchbase.com/releases/6.0.0/couchbase-server-community-6.0.0-centos7.x86_64.rpm

sudo yum install -y couchbase-server-community-6.0.0-centos7.x86_64.rpm

Set the file limits in the limits.conf file:

sudo vim /etc/security/limits.conf

Add these lines:

* soft nofile 75000
* hard nofile 75000

Start the Couchbase server:

sudo /opt/couchbase/bin/couchbase-server \-- -noinput -detached

Challenge

Create the Bucket and Test Data

From the GUI, simply add bucket.
From the CLI

couchbase-cli bucket-create -c 127.0.0.1:8091 --username Administrator --password Omgpassword! --bucket testdata --bucket-type couchbase --bucket-ramsize 128

Connect to couchbase using cbq

   cbq -e http://127.0.0.1:8091 -u=Administrator

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.

INSERT INTO `testdata` (KEY,VALUE) VALUES
("Employee_Duck",
{"name":"Donald Duck",
"status":"active",
"phone":{"primary":"5551212","secondary":"8329050"}}),
("Employee_James",
{"name":"Jimmy James",
"status":"active",
"phone":{"primary":"8001234","secondary":"none"}}),
("Employee_Solo",
{"name":"Han Solo",
"status":"retired",
"phone":{"primary":"none","secondary":"none"}}),
("Employee_Bacca",
{"name":"Chew Bacca",
"status":"retired",
"phone":{"primary":"6123478","secondary":"6461234"}});

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`;
```
