How to install Cockpit on Oracle Linux 8.8

To Install Cockpit On Oracle Linux 8.8

Introduction:

Cockpit is an intuitive web-based console that lets you manage your server using an easy-to-use web interface. The Cockpit web console operates the same system APIs as a terminal, and tasks performed in a terminal are almost mirrored in the web console. Furthermore, you can configure the settings instantly in the web console or through the terminal.

Installation Steps:

Step 1: Check the Oracle Linux version by using the below command

[root@linuxhelp ~]# cat /etc/os-release
NAME="Oracle Linux Server"
VERSION="8.8"
ID="ol"
ID_LIKE="fedora"
VARIANT="Server"
VARIANT_ID="server"
VERSION_ID="8.8"
PLATFORM_ID="platform:el8"
PRETTY_NAME="Oracle Linux Server 8.8"
ANSI_COLOR="0;31"
CPE_NAME="cpe:/o:oracle:linux:8:8:server"
HOME_URL="https://linux.oracle.com/"
BUG_REPORT_URL="https://github.com/oracle/oracle-linux"
ORACLE_BUGZILLA_PRODUCT="Oracle Linux 8"
ORACLE_BUGZILLA_PRODUCT_VERSION=8.8
ORACLE_SUPPORT_PRODUCT="Oracle Linux"
ORACLE_SUPPORT_PRODUCT_VERSION=8.8

Step 2: Install Cockpit web console package by using the below command

[root@linuxhelp ~]# yum install cockpit

Package cockpit-286.1-1.0.1.el8.x86_64 is already installed.
Dependencies resolved.
Nothing to do.
Complete!

Step 3: Enable the Cockpit service by using the below command

[root@linuxhelp ~]# systemctl enable cockpit.service
The unit files have no installation config (WantedBy, RequiredBy, Also, Alias
settings in the [Install] section, and DefaultInstance for template units).
This means they are not meant to be enabled using systemctl.
Possible reasons for having this kind of units are:
1) A unit may be statically enabled by being symlinked from another unit's
   .wants/ or .requires/ directory.
2) A unit's purpose may be to act as a helper for some other unit which has
   a requirement dependency on it.
3) A unit may be started when needed via activation (socket, path, timer,
   D-Bus, udev, scripted systemctl call, ...).
4) In case of template units, the unit is meant to be enabled with some
   instance name specified.

Step 4: Start the Cockpit service by using the below command

[root@linuxhelp ~]# systemctl start cockpit.service

Step 5: Check the Status of Cockpit service by using the below command

[root@linuxhelp ~]# systemctl status cockpit.service
? cockpit.service - Cockpit Web Service
   Loaded: loaded (/usr/lib/systemd/system/cockpit.service; static; vendor pres>
   Active: active (running) since Mon 2023-07-10 04:36:18 IST; 18s ago
     Docs: man:cockpit-ws(8)

Jul 10 04:36:18 linuxhelp systemd[1]: Started Cockpit Web Service.

Step 6: If you are running a firewalld on the system, you need to open the cockpit port 9090 in the firewall by using the below command.

[root@linuxhelp ~]# firewall-cmd --add-service=cockpit --permanent
Warning: ALREADY_ENABLED: cockpit
success
[root@linuxhelp ~]# firewall-cmd --reload
Success

Step 7: Open the Cockpit web console in your web browser by using the below URL’s:

Locally: https://localhost:9090
Remotely with the server’s hostname: https://example.com:9090
Remotely with the server’s IP address: https://192.168.6.136:9090

Step 8: If you are using a self-signed certificate, you will get a warning on the browser, simply verify the certificate and accept the security exception to proceed further with the login as shown in the below image.

Step 9: In the web console login screen, enter your system user name and password as shown in the below image.

Step 10: After successful authentication, the Cockpit web console interface opens as shown in the below image.
