Cockpit is an open source application based on a web interface that allows you to control, monitor and manage the operation of a Linux server. Among its main features are its ease of installation and its bright design that makes it very simple to use.

Others Features

In order to be a program used by multiple teams working on a server is that Cockpit has been carefully designed. In addition, it is friendly enough for those new to Linux and useful for seasoned admins too.

As I mentioned before, the installation of Cockpit is really simple since it is included in the official repositories of many Linux distributions.

As expected many sysadmins are experts in the use of the terminal and therefore using Cockpit is perfectly compatible with it. There’s even an embedded terminal in Cockpit.

In short, we are talking about a necessary program to complement the administration of a server efficiently.

Installing Cockpit on Ubuntu 20.04 / 18.04

In previous versions of Ubuntu like 16.04, to install Cockpit you had to use external repositories. Ubuntu version 20.04/ 18.04 includes Cockpit in its repositories, so installing it is a very simple process. Open a terminal and run:

:~$ sudo apt install cockpit

Then, start the service and finally, check the service status.

:~$ sudo systemctl start cockpit
:~$ sudo systemctl status cockpit

Cockpit is installed.

Using Cockpit

Now to use Cockpit, open a web browser, and access using port 9090 http://IP_SERVER:9090 and you will see the login screen.

Enter your username and password and log in to view the application dashboard.

In this first screen, you will get essential information about the system, such as Network traffic, RAM or CPU load.

Logs Screen

In the logs screen, you will be able to access the logs generated by the system. Very important to verify possible errors in the operation of programs.

Storage screen

In the Storage screen, you will see the information concerning the hard drives the server has. You will also be able to access the logs generated in that section.

As you can see in the image, it is possible to create Raid devices in a quite simple way. Also if you click on Drives you can have access to the information of each one of them.

Networking screen

In this section, you can notice the network traffic from the server. In this case, it is a test server and the traffic is null, but if you have one in production it will look different.

However, you can add a VLAN or a Bridge to your network.

Accounts Screen

Here you can get information about the active user accounts on the server.

You can also delete the account or close the session.

Services Screen

This is a vital section of the program because here you can view in a fairly simple way, all the services that are installed on the server and also know which is running and which is not.

On the other hand, if you click on a service, you can activate it, deactivate it or disable it so that it does not run when you start the system.

Showing the terminal on Cockpit

Cockpit also integrates a terminal emulator directly into your application, which makes it a great utility for the administration.

Conclusion

Managing a system is not an easy task, that’s why specialized applications are required to facilitate the task. Cockpit combines the simplicity of a fairly polished web interface with the robustness of having great options available.

In that Log in screen, you only have to put your system credentials. Yes, the same ones you use to log in. If your user is in the sudo list you can check the option to reuse my password for privileged tasks. When you log in, you will see the following.

On the left side, you have all the driving options. For example, you can check the system logs:

In this case, there isn’t one in my system yet.

Then you can check the storage function.

A very useful function of Cockpit is the ability to monitor the state of the computer networks.

Also, managing system services such as postgreSQL, MariaDB or FTP are very easy thanks to Cockpit.

The sysadmin will appreciate that Cockpit includes a terminal ready to execute commands:

On the other hand, you can see the Cockpit dashboard there you will have information about the system resources.

So, enjoy this wonderfull tool.

Conclusion

Cockpit is one of those tools that works quite well and easily. That is, without complicated interfaces we can control a Linux server through a web interface. Now you know how to install it in Debian 10.

Cockpit is a web application that allows you to control one server or several Linux servers. Everything from a web interface that you can open from your favorite web browser. In this way, we can perform common and not so common tasks on the server with just a few clicks.

Using Cockpit It is easy to start containers, administer storage, configure networks, and inspect logs.

On the other hand, Cockpit gets along very well with after-server applications such as Ansible. This means that the integration with the server is practically complete. In addition, the application is quite well supported by its creators and is available for the largest Linux distributions.

Install Cockpit on OpenSUSE 15.1

The easiest way to install Cockpit on OpenSUSE 15.1 is through a distribution-specific repository. However, this is not enabled by default, so you have to enable it first.

Open a terminal emulator or connect to your server using ssh.

Then, add the repository with the following command:

:~$ sudo zypper addrepo https://download.opensuse.org/repositories/systemsmanagement:cockpit/openSUSE_Leap_15.1/systemsmanagement:cockpit.repo

And restart the firewall service:

:~$ sudo firewall-cmd --reload
success

Now we can really use it.

Using Cockpit

Once we have installed Cockpit, we can open a favorite web browser and access https://your-server:9090

Replace your-server by the IP address of the computer or by the domain name.

You will see the following:

you must now log in with your username and password. The same ones you use for the system. Then, you will see the following:

As you can see, the system information is displayed. But you can also check the system logs on the left side.

Moreover, you can also easily create new users of the system.

You can also see the services of the system.

Cockpit even has a built-in terminal in case you need to run a command quickly.

So, enjoy it.

Cockpit makes server management much easier

Cockpit is a web application that allows you to control one server or several Linux servers. Everything from a web interface that you can open from your favorite web browser. In this way, we can perform common and not so common tasks on the server with just a few clicks.

Using Cockpit It is easy to start containers, administer storage, configure networks, and inspect logs.

On the other hand, Cockpit gets along very well with after-server applications such as Ansible. This means that the integration with the server is practically complete. In addition, the application is quite well supported by its creators and is available for the largest Linux distributions.

So, we can say that Cockpit makes server management easier.

Install Cockpit on CentOS 8

In order for Cockpit to be able to read the proper information from the system, it is a good idea to update it first. To do this, connect to your server using SSH and run the following:

:~$ su
:~# dnf update

Now the system is ready for Cockpit.

Fortunately, Cockpit comes by default in the default CentOS 8 repositories. This causes the installation to be condensed in a single command.

:~# dnf install cockpit

Then, it will start downloading and installing all the necessary packages.

Cockpit is managed as a service. Therefore, we can start it, stop it and restart it in a similar way to Apache or MariaDB using systemctl. Then you have to start it:

:~# systemctl start cockpit

It is advisable that Cockpit is started with the system, if that is what you want, use this command:

:~# systemctl enable cockpit

Finally, to verify that everything has worked out correctly, you can check the status of the service.

:~# systemctl status cockpit

After that, we need to open the Cockpit ports in the firewall so that we can run it from the web browser.

:~# firewall-cmd --add-service=cockpit --permanent --zone=public
:~# firewall-cmd --reload
success

Now, we can use it from the web browser.

Using Cockpit

Once we access http://your-server:9090 we will see the following screen.

In this screen, you will have to log in with your system credentials. Then, you will see the Dashboard.

With Cockpit, you can see the system logs. But also the network settings. Even tasks like adding a bridge are done with a few clicks. You can also see the network activity.

On the left side, you will have all the options available. Also, an important aspect of the application is that it allows the management of system services graphically.

Finally, the application has a terminal emulator integrated with the system. This if you need to perform a specific command or something else.

So, now you can use it.

Conclusion

There are many tools that allow us to manage a server more effectively. Cockpit is one of those tools that with a bright and polished graphical interface can perform common tasks and not so common on a Linux server. Thus, in this post, you have learned to install it on CentOS 8. And see some of its modules.

So, you can learn more about CentOS 8 reading our posts.
