  • How to Migrate CentOS 7 to AlmaLinux 8

    How to Migrate CentOS 7 to AlmaLinux 8

    Upgrade CentOS 7 to latest version with

    yum update -y

    Reboot the server

    reboot

    Install elevate repo rpm file

    yum install -y http://repo.almalinux.org/elevate/elevate-release-latest-el$(rpm --eval %rhel).noarch.rpm

    Install leapp

    yum install -y leapp-upgrade leapp-data-almalinux

    Run pre upgrade check

    leapp preupgrade

    After the preupgrade script run, it will generate a log file /var/log/leapp/leapp-report.txt, you need to fix any problems reported in this file.

    On CentOS 7, you need to run these 2 commands as they will cause upgrade blocking.

    rmmod pata_acpi
leapp answer --section remove_pam_pkcs11_module_check.confirm=True

    Run the upgrade

    leapp upgrade

    During the upgrade, server will reboot itself. This process can take a while to finish. Don’t interrupt the process or you will end up with non working server.

    Once the upgrade process is finished, reboot the server.

    reboot
  • How to configure IPv6 on OVH AlmaLinux 8 server

    How to configure IPv6 on OVH AlmaLinux 8 server

    First, find the network interface used by the server with ip a command.

    [root@15-204-47-122 ~]# ip a
1: lo:  mtu 65536 qdisc noqueue state UNKNOWN group default qlen 1000
    link/loopback 00:00:00:00:00:00 brd 00:00:00:00:00:00
    inet 127.0.0.1/8 scope host lo
       valid_lft forever preferred_lft forever
    inet6 ::1/128 scope host 
       valid_lft forever preferred_lft forever
2: eno1:  mtu 1500 qdisc mq state UP group default qlen 1000
    link/ether a8:a1:59:c0:de:80 brd ff:ff:ff:ff:ff:ff
    altname enp3s0f0
    inet 15.204.47.122/24 brd 15.204.47.255 scope global eno1
       valid_lft forever preferred_lft forever
    inet6 fe80::aaa1:59ff:fec0:de80/64 scope link 
       valid_lft forever preferred_lft forever
3: enp3s0f1:  mtu 1500 qdisc noop state DOWN group default qlen 1000
    link/ether a8:a1:59:c0:de:81 brd ff:ff:ff:ff:ff:ff
4: enp0s20f0u8u3c2:  mtu 1500 qdisc noop state DOWN group default qlen 1000
    link/ether 5a:58:d0:03:8e:b3 brd ff:ff:ff:ff:ff:ff
[root@15-204-47-122 ~]#

    The interface eno1 has the public IPv4 address of the server associated, so it is the public interface used by the server.

    Find the IPv6 IP address and gateway, This you can find in the OVH Manager server details page.

    OVH Server manager network details IPv6

    Edit ifcfg file for the network interface

    vi /etc/sysconfig/network-scripts/ifcfg-eno1

    At the end of the configuration, add

    IPV6INIT=yes
IPV6_AUTOCONF=no
IPV6_FAILURE_FATAL=no
IPV6ADDR=2604:2dc0:200:1f7a::/64

    2604:2dc0:200:1f7a::/64 – is the IPv6 IP address found in OVH Manager.

    Here is the full configuration 

    BOOTPROTO=static
DEVICE=eno1
HWADDR=a8:a1:59:c0:de:80
IPADDR=15.204.47.122
NETMASK=255.255.255.0
GATEWAY=15.204.47.254
ONBOOT=yes
TYPE=Ethernet
USERCTL=no
IPV6INIT=yes
IPV6_AUTOCONF=no
IPV6_FAILURE_FATAL=no
IPV6ADDR=2604:2dc0:200:1f7a::/64

    Create route file

    vi /etc/sysconfig/network-scripts/route6-eno1

    Add

    2604:2dc0:0200:1fff:00ff:00ff:00ff:00ff dev eno1
default via 2604:2dc0:0200:1fff:00ff:00ff:00ff:00ff

    Here ‘2604:2dc0:0200:1fff:00ff:00ff:00ff:00ff” is gateway address you get from OVH Manager server network page. eno1 is your public network interface name.

    After reboot, the IPv6 network will work on the server.

  • How to install docker on AlmaLinux 8

    How to install docker on AlmaLinux 8

    To install docker on AlmaLinux, run the following commands

    Install yum-utils

    dnf install -y yum-utils

    Add docker repository

    yum-config-manager --add-repo https://download.docker.com/linux/centos/docker-ce.repo

    Install Docker CE with

    dnf install docker-ce

    Enable docker

    systemctl enable docker

    Start Docker

    systemctl start docker

    To verify if docker is working properly, run

    docker run hello-world

    Example

    [root@cloud ~]# docker run hello-world
Unable to find image 'hello-world:latest' locally
latest: Pulling from library/hello-world
2db29710123e: Pull complete 
Digest: sha256:94ebc7edf3401f299cd3376a1669bc0a49aef92d6d2669005f9bc5ef028dc333
Status: Downloaded newer image for hello-world:latest

Hello from Docker!
This message shows that your installation appears to be working correctly.

To generate this message, Docker took the following steps:
 1. The Docker client contacted the Docker daemon.
 2. The Docker daemon pulled the "hello-world" image from the Docker Hub.
    (amd64)
 3. The Docker daemon created a new container from that image which runs the
    executable that produces the output you are currently reading.
 4. The Docker daemon streamed that output to the Docker client, which sent it
    to your terminal.

To try something more ambitious, you can run an Ubuntu container with:
 $ docker run -it ubuntu bash
