RKE2 server node installation #4507
-
|
I am trying to install an rke2 cluster, starting with the server node. Fistly I disabled the firewalld ( my VM's OS is Centos 7 ), and then proceeded with the following commands : mkdir -p /etc/rancher/rke2/
curl -sfL https://get.rke2.io | INSTALL_RKE2_CHANNEL=v1.24 INSTALL_RKE2_TYPE=server sh -
systemctl enable rke2-server.service
systemctl start rke2-server.servicebut the rke2-server.service hasn't changed the activating state since then and shows these logs : ● rke2-server.service - Rancher Kubernetes Engine v2 (server)

No, actually, it is not. As I mentioned previously, I used the above command to install the RKE2 server. |

OK well DNS lookups are timing out; there's not really much to troubleshoot or configure there. What does your resolv.conf point at for DNS? Can you confirm that all of the listed nameservers are functional? Do you need to configure RKE2 to use a proxy server? |

yes I am behind a proxy server, what do you mean by configuring RKE2 to use the porxy server ? because the vm is already configured with the proxy server |

OK, well that would have been a good thing to mention up front. Just because your interactive shell has the HTTP_PROXY environment variables set, does not mean that they are also set for systemd services. See the documentation at https://docs.rke2.io/advanced#configuring-an-http-proxy |

Can I ask you a question: Is it possible for RKE2 to work without disabling the firewalld ? |

Possible, but not supported. There are some pointers in the documentation if you want to try. |
