0x02 食用指南

Fedora

Cockpit comes installed by default in Fedora Server.
To install Cockpit on other variants of Fedora use the following commands. For the latest versions use COPR.

1.Install cockpit:

sudo dnf install cockpit

2.Enable cockpit:

sudo systemctl enable --now cockpit.socket

3.Open the firewall if necessary:

sudo firewall-cmd --add-service=cockpit
sudo firewall-cmd --add-service=cockpit --permanent

Red Hat Enterprise Linux

Cockpit is included in Red Hat Enterprise Linux 7 and later.
On RHEL 7, enable the Extras repository.
sudo subscription-manager repos --enable rhel-7-server-extras-rpms
RHEL 8 does not need any non-default repositories.

1.Install cockpit:

sudo yum install cockpit

2.Enable cockpit:

sudo systemctl enable --now cockpit.socket

3.On RHEL 7, or if you use non-default zones on RHEL 8, open the firewall:

sudo firewall-cmd --add-service=cockpit
sudo firewall-cmd --add-service=cockpit --permanent

Fedora CoreOS

The standard Fedora CoreOS image does not contain Cockpit packages.
1.Install Cockpit packages as overlay RPMs:

rpm-ostree install cockpit-system cockpit-ostree cockpit-podman 

Depending on your configuration, you may want to use other extensions as well, such as cockpit-kdump or cockpit-networkmanager.
If you have a custom-built OSTree, simply include the same packages in your build.
2.Reboot
3.Run the Cockpit web service with this privileged container (as root):

podman container runlabel --name cockpit-ws RUN cockpit/ws

4.Make Cockpit start on boot:

podman container runlabel INSTALL cockpit/ws
systemctl enable cockpit.service

Steps 3 and 4 are optional if the CoreOS machine will only be connected to from another host running Cockpit.

CentOS

Cockpit is included in CentOS 7.x:
1.Install cockpit:

sudo yum install cockpit

2.Enable cockpit:

sudo systemctl enable --now cockpit.socket

3.Open the firewall if necessary:

sudo firewall-cmd --reload

Afterward, use a web browser to log into port 9090 on your host IP address as usual.

Cockpit is included in Debian unstable and in backports for 9 (Stretch).
