In this hands-on lab, we will install and initialize a Couchbase server on CentOS 7. Once that is complete, we will create a bucket and create some test data.
Learning Objectives
Successfully complete this lab by achieving the following learning objectives:
- 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.rpmsudo yum install -y couchbase-server-community-6.0.0-centos7.x86_64.rpmSet the file limits in the
limits.conffile:sudo vim /etc/security/limits.confAdd these lines:
* soft nofile 75000 * hard nofile 75000Start the Couchbase server:
sudo /opt/couchbase/bin/couchbase-server -- -noinput -detached
- 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 128Connect to couchbase using cbq
cbq -e http://127.0.0.1:8091 -u=AdministratorLocate the data in the
~/datafolder. 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"}});
- Confirm the Data Was Created Correctly
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`;
