CouchDB is a popular NoSQL database developed and maintained by Apache Foundation since 2005. It is an open-source database written in Erlang language that provides a RESTful API that users can use to create and modify database objects. CouchDB provides a document-oriented architecture and presents data as key-value pairs.<\/p>\n

Now, let us install CouchDB on Ubuntu 20.04 LTS.<\/p>\n

Step 1: Install prerequisite packages<\/strong><\/h2>\n

The first step involves installing the prerequisite packages that will be required later in the installation. To run the following command:<\/p>\n

$ sudo apt install curl<\/strong><\/pre>\n
 <\/strong><\/p>\n
Next, Install the GPG key for encryption and signing of data.<\/p>\n
$ sudo apt install gnupg ca-certificates -y<\/strong><\/pre>\n
<\/strong><\/p>\n
Step 2: Enable CouchDB repository<\/strong><\/h2>\n
Before you enable the CouchDB repository, be sure to install the repository key as follows:<\/p>\n
$ sudo apt-key adv --keyserver keyserver.ubuntu.com --recv-keys 8756C4F765C9AC3CB6B85D62379CE192D401AB61<\/strong><\/pre>\n
<\/strong><\/p>\n
Then add CouchDB repository to the sources list file as follows:<\/p>\n
$ echo \"deb https:\/\/apache.bintray.com\/couchdb-deb focal main\" >> \/etc\/apt\/sources.list<\/strong><\/pre>\n
<\/strong><\/p>\n
Once you have added the CouchDB repository, update the package lists to sync the repository.<\/p>\n
$ sudo apt update<\/strong><\/pre>\n
<\/strong><\/p>\n
Step 3: Install couchDB<\/strong><\/h2>\n
You can now proceed to install CouchDB as follows as a sudo user.<\/p>\n
$ sudo apt install couchdb<\/strong><\/pre>\n
<\/strong><\/p>\n
The installation requires you to select the CouchDB configuration mode. There are two types of configuration:<\/p>\n
    \n
  1. Standalone mode<\/strong>: This is used when dealing with a single server instance.<\/li>\n
  2. Clustered<\/strong>: As the name suggests, this is used when you have multiple servers that are interconnected.<\/li>\n<\/ol>\n
    Since this guide demonstrates the installation on a single server, we will go with the \u2018Standalone<\/strong>\u2019 option.<\/p>\n
    <\/strong><\/p>\n
    Next, be sure to specify the bind-address. By default, this is set to the localhost address which is just okay for a standalone server. Just press ENTER.<\/p>\n
    <\/strong><\/p>\n
    Next, set a strong password for the Admin user.<\/p>\n
    <\/strong><\/p>\n
    Confirm the password and hit ENTER.<\/p>\n
    <\/strong><\/p>\n
    Afterward, the installation will continue running and complete.<\/p>\n
    Step 4: Test couchDB<\/strong><\/h2>\n
    To verify that the installation went as expected, use the curl command to retrieve basic information about CouchDB in JSON format;<\/p>\n
    $ curl http:\/\/127.0.0.1:5984<\/strong><\/pre>\n
    You will get a set of output as indicated below<\/p>\n
    <\/strong><\/p>\n
    CouchDB listens to port 5984 and you can confirm this by initiating the command:<\/p>\n
    $ sudo netstat -pnltu | grep 5984<\/strong><\/pre>\n
    <\/strong><\/p>\n
    When CouchDB is installed, two databases are created by default. These are replicator and users databases. To verify this, browse the URL below:<\/p>\n
    http:\/\/127.0.0.1:5984\/_utils<\/strong><\/a><\/pre>\n
    Provide the login details with \u2018admin<\/strong>\u2019 as the username and the password that you provided during the installation process in Step 3.<\/p>\n
    <\/strong><\/p>\n
    This ushers you to the couchDB database below.<\/p>\n
    <\/strong><\/p>\n
    Those two tests confirm that CouchDB is successfully installed. Bravo!<\/p>\n
    Hopefully, you are now in a comfortable position to install CouchDB on your system.<\/p>","protected":false},"excerpt":{"rendered":"
