Installing Dependencies

Execute the bellow commands to install the required packages.

sudo apt update
sudo apt install -y curl apt-transport-https gnupg -y
sudo apt install ncurses-term -y

Enabling CouchDB repository

Enabling the vendor repository and installing the binary packages is the simplest way to install CouchDB on CentOS 8.

For the CouchDB, repository to be enabled and the GPG key to be imported, use the following commands as root or a user with sudo privileges:

curl https://couchdb.apache.org/repo/keys.asc | gpg --dearmor | sudo tee /usr/share/keyrings/couchdb-archive-keyring.gpg >/dev/null 2>&1

source /etc/os-release

echo "deb [signed-by=/usr/share/keyrings/couchdb-archive-keyring.gpg] https://apache.jfrog.io/artifactory/couchdb-deb/ ${VERSION_CODENAME} main" | sudo tee /etc/apt/sources.list.d/couchdb.list >/dev/null

Installing CouchDB on Debian

Update the packages list and install CouchDB after the repository has been enabled:

sudo apt update
sudo apt install couchdb

You will first be prompted by the installer to choose between standalone and clustered installation modes for CouchDB. We will set up CouchDB in standalone mode on a single server.

Following that, you will be given the option of specifying the IP address of the network interface to which CouchDB will bind to. Leave the default 127.0.0.1 address alone for single-server configuration. When setting up a cluster, either type 0.0.0.0 to inform CouchDB to bind to all network interfaces or enter the interface IP address.

Set the admin password when the next prompt appears. Setting a password and removing CouchDB from the insecure “admin party” mode are strongly advised. The admin user is not created if this field is left empty.

The password must be verified for the installation to continue.

Verifying CouchDB Installation

The CouchDB server is active at localhost:5984. The following curl command will print information about the CouchDB database in JSON format, allowing you to verify that the installation was successful, and the service is up and running:

curl http://127.0.0.1:5984/

The result will appear as follows:

Output

{
   "couchdb":"Welcome",
   "version":"3.0.0",
   "git_sha":"03a77db6c",
   "uuid":"adab3f42ce6a06245d2955c1d6832266",
   "features":[
      "access-ready",
      "partitioned",
      "pluggable-storage-engines",
      "reshard",
      "scheduler"
   ],
   "vendor":{
      "name":"The Apache Software Foundation"
   }
}

The output is formatted for clarity.
