Installation and Deployment ​

sysmaster can be used in containers and VMs. This document uses the AArch64 architecture as an example to describe how to install and deploy sysmaster in both scenarios.

Software ​

• OS: openEuler 23.09

Hardware ​

• x86_64 or AArch64 architecture

Installation and Deployment in Containers ​

1. Install Docker.

   bash

   yum install -y docker
   systemctl restart docker

2. Load the base container image.

   Download the container image.

   bash

   wget https://repo.openeuler.org/openEuler-23.09/docker_img/aarch64/openEuler-docker.aarch64.tar.xz
   xz -d openEuler-docker.aarch64.tar.xz

   Load the container image.

   bash

   docker load --input openEuler-docker.aarch64.tar

3. Build the container.

   Create a Dockerfile.

   bash

   cat << EOF > Dockerfile
   FROM openeuler-23.09
   RUN yum install -y sysmaster
   CMD ["/usr/lib/sysmaster/init"]
   EOF

   Build the container.

   bash

   docker build -t openeuler-23.09:latest .

4. Start and enter the container.

   Start the container.

   bash

   docker run -itd --privileged openeuler-23.09:latest

   Obtain the container ID.

   bash

   docker ps

   Use the container ID to enter the container.

   bash

   docker exec -it <container ID> /bin/bash

Installation and Deployment in VMs ​

1. Create an initramfs image. To avoid the impact of systemd in the initrd phase, you need to create an initramfs image with systemd removed and use this image to enter the initrd procedure. Run the following command:

   bash

   dracut -f --omit "systemd systemd-initrd systemd-networkd dracut-systemd" /boot/initrd_withoutsd.img

2. Add a boot item. Add a boot item to grub.cfg, whose path is /boot/efi/EFI/openEuler/grub.cfg in the AArch64 architecture and /boot/grub2/grub.cfg in the x86_64 architecture. Back up the original configurations and modify the configurations as follows:

   • menuentry: Change openEuler (6.4.0-5.0.0.13.oe23.09.aarch64) 23.09 to openEuler 23.09 withoutsd.
   • linux: Change root=/dev/mapper/openeuler-root ro to root=/dev/mapper/openeuler-root rw.
   • linux: If Plymouth is installed, add plymouth.enable=0 to disable it.
   • linux: Add init=/usr/lib/sysmaster/init.
   • initrd: Set to /initrd_withoutsd.img.

3. Install sysmaster.

   bash

   yum install sysmaster

4. If the openEuler 23.09 withoutsd boot item is displayed after the restart, the configuration is successful. Select openEuler 23.09 withoutsd to log in to the VM.
