In today's post we will tell you how we access our Linux system with the help of web console
We do this because RedHat is a CLI based operating system and there are some things we don't understand so we use the web console

To access through web console you need to follow some steps mentioned below
Here you have to install some packages first and then enable the services
[root@redhat-1 ~]# [root@redhat-1 ~]# sudo dnf install cockpit

Here you can see that your Cockpit package has been successfully installed
If you want to check whether cockpit package is already installed in your system then you can check with this command
[root@redhat-1 ~]# rpm -qa | grep cockpit cockpit-bridge-276.1-1.el9.x86_64 cockpit-system-276.1-1.el9.noarch cockpit-storaged-276.1-1.el9.noarch subscription-manager-cockpit-4-1.el9.noarch cockpit-packagekit-276.1-1.el9.noarch cockpit-ws-276.1-1.el9.x86_64 cockpit-podman-53-1.el9.noarch cockpit-286.1-1.el9.x86_64 [root@redhat-1 ~]#
Once Cockpit package installed successfully, you can start, enable and verify the service and running process using the following commands.
[root@redhat-1 ~]# systemctl start cockpit.socket [root@redhat-1 ~]# systemctl enable cockpit.socket Created symlink /etc/systemd/system/sockets.target.wants/cockpit.socket → /usr/lib/systemd/system/cockpit.socket. [root@redhat-1 ~]#
Your Cockpit Package has been start and enabled successfully.
If you want to see the status of your cockpit package whether your service is started or not then you can see with this command.
[root@redhat-1 ~]# systemctl status cockpit.socket
● cockpit.socket - Cockpit Web Service Socket

Jul 08 02:08:24 redhat-1 systemd[1]: Starting Cockpit Web Service Socket...
Jul 08 02:08:24 redhat-1 systemd[1]: Listening on Cockpit Web Service Socket.
[root@redhat-1 ~]#
To access Cockpit web console, you need to allow the services in the firewall.
[root@redhat-1 ~]# firewall-cmd --add-service cockpit Warning: ALREADY_ENABLED: 'cockpit' already in 'public' success [root@redhat-1 ~]# firewall-cmd --add-service cockpit --perm Warning: ALREADY_ENABLED: cockpit success [root@redhat-1 ~]#
Now by default, Cockpit accepts connection on port TCP port 9090. use the ss command to view open port:
[root@redhat-1 ~]# sudo ss -tulpn | grep :9090
tcp LISTEN 0 4096 *:9090 *:* users:(("systemd",pid=1,fd=287))
[root@redhat-1 ~]#
Now open your browser and type IP address and port number of your Linux Machine something like this.
192.168.199.107:9090
Now the login page of Redhat will come, here you have to enter your user id and password of Linux machine.
After login, you can see here there is an option of all the services which you can easily manage.
Now if you want to disable its services then you can do it with the help of this command
[root@redhat-1 ~]# systemctl stop cockpit.socket [root@redhat-1 ~]# systemctl disable cockpit.socket Removed "/etc/systemd/system/sockets.target.wants/cockpit.socket". [root@redhat-1 ~]#
Note:- Now you can access this web console
services from anywhere on the same network but you have to access this web
console services from another network then you can access using public IP, and
port forwarding has to be enabled from the router.
If you have any problem in this or do not understand, then you can contact me.
