If we are accessing using root user, we don't need to enter sudo everytime we run the commands but as we are running a non- root user, we'll need to enter sudo at every command in order to access root privileges. As we have Ubuntu PPA repository of Apache Couch. DB maintained and updated by the Couch. DB project and the communities, we'll gonna go for it. Installing Couch. DB using PPA repository is the most easiest and simple method to install the official release of Couch. DB. First of all, we'll need to make sure that we have installed the package named software- properties- common so that we can easily add the PPA repository in our Ubuntu machine. In order to install it, we'll need to execute the following command. In order to install Couch. DB from the official PPA repository, we can now simply run the following apt- get command in our terminal. This will install couchdb with its required dependencies from their respective repositories. In order to fix the issue, we'll need to change the ownership of the files belonging to the couchdb user and group.
As the new user and group for couchdb is already created by default during the installation process above, we'll no need to create another. In order to change the ownership, we'll simply need to run the following command. In order to do so, as we are running Ubuntu 1. LTS Xenial and its shipped with systemd as the default init system, we'll need to run the following command. In order to do so, we'll first need to perform SSH tunneling as allowing Futon across the firewall currently may be dangerous as we haven't set a proper admin credentials. In order to setup SSH tunneling, we'll need to run the following command. To do so, we'll need to open a web browser and point it to http: //localhost: 5. Then, in order to access the web application of Futon, we'll need to point to http: //localhost: 5. Once done, we'll get access to the Futon Database Administration Panel in which we can perform different Couch. DB database management activities. Securing Futon. As we don't require any login credentials to login to the Futon panel and as every account is an admin account in it, anyone accessing Futon has the ability to make changes to the database. So, first of all, we'll need to secure it by creating a new Admin account. To do so, we can simply click on Fix it link shown in the bottom of the right- sidebar. Doing so will open a dialogue box allowing us to create a new admin account. Here, we'll need to enter the required username and password which we'll use further to login to Futon. Creating Databases. Now, in order to create a database, we'll need to login to Futon Control Panel using the username and password created above. Then, we'll click on Create Database button available on the top- left of the screen. Then, we'll be asked to enter a name for our new database to be created. Next, we can add new documents, edit, delete, update and save the documents via Futon easily. Allowing External Access. If you need to make Couch. DB accessible and available outside of our local network or our local machine, then we'll need to make sure that the above steps on securing Futon is completed. Then, we'll need to add 0. To do so, we'll need to login as root user and open the file using a text editor. Once done, we'll gonna save the file and exit the text editor. Once done, we can simply log out from the root user by executing exit command in the terminal. Now, in order to apply the changes, we'll need to restart our Couch. DB services using systemctl command. As Ubuntu 1. 6. 0. LTS Xenial runs with systemd as the default init system, firewalld is most probably used as the firewall program. So, its not recommended to allow Couch. DB accessible externally, if we need access to it remotely, we can make use of SSH tunneling or allow a specific ip address to connect via iptables or firewall program. Conclusion. Finally, we have easily and succesfully installed Couch. DB with its web based interface Futon in our machine running Ubuntu 1. LTS Xenial. Documents and databases in Couch. DB can be easily accessible by everyone so we'll need to make sure that our database is not accessible by public or untrusted people.
