In this post, I will show you how to install CouchDB on CentOS 8.
On the other hand, CouchDB places a lot of emphasis on data replication as a persistent way to obtain data. That is, we will be able to connect multiple nodes and from there do the replication.
Of course, there are a lot of features and reasons why this project of the Apache Foundation is so important today.
So, let us start.
Install CouchDB on CentOS 8
There are several ways to install CouchDB on CentOS 8. Perhaps the most complex is to compile the program ourselves. Of course, this option guarantees that you always get the latest stable version.
On the other hand, there is the option of downloading and installing pre-compiled binary packages. And finally, we can install CouchDB on CentOS using the application repository. This last one will be the option to choose.
So let’s get started.
First, we need to add the CouchDB repository for CentOS 8. To do this, we need to create a text file in the system’s repository directory.
:~# nano /etc/yum.repos.d/bintray-apache-couchdb-rpm.repo
And in it, add the following content:
Save the file and close it.
Then, the EPEL repository must be enabled. You can do it quickly, with the following command
:~# dnf install epel-release
If you want more information about how to enable the EPEL repository, I recommend you to read our post:
After this, we can install couchDB with the following command:
:~# dnf install couchdb
And that’s it. However, before using it, there are some settings to be made.
Preparing CouchDB for the first use
Remember that CouchDB works through port 5984. So, the first thing is to open that port in the firewall.
:~# firewall-cmd --add-port=5984/tcp --permanent --zone=public
And then, restart the firewall to apply the changes.
:~# firewall-cmd --reload
Now we have to enable the CouchDB web interface.
So, open the CouchDB configuration file and find the
admins section and set a password there for the admin user.
:~# nano /opt/couchdb/etc/local.ini
admin = your-password
Then go to the
chttpd section in the same file and uncomment the
bind_address lines. In the port you can change the default port of the application. And in Bind_address the IP address that serves the interface. If you are going to use a cluster, you must type
port = 5984
bind_address = 0.0.0.0
Now if you can, save and close the file.
Finally, the CouchDB service begins. It is also a good idea to enable it to start with the system.
:~# systemctl enable couchdb
:~# systemctl start couchdb
CouchDB on CentOS 8
Now open your favorite web browser and go to
http://your-server:5984/_utils and you will see the Login screen.
Just type your credentials and click on the Log in button. You will see this:
Finally, you can test the installation.
So, enjoy it.
CouchDB is clearly oriented to the professional web sector. However, its learning curve is low with respect to its power. Despite this, CouchDB is easily installable as we have seen.
