Installation and Deployment ​

The sysmaster service 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 22.03 LTS SP4

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-22.03-LTS-SP4/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 based on the image name queried by the docker images command, for example, openEuler-22.03-LTS-SP4.

   bash

   cat << EOF > Dockerfile
   FROM openEuler-22.03-LTS-SP4
   RUN yum install -y sysmaster
   CMD ["/usr/lib/sysmaster/init"]
   EOF

   Build the container.

   bash

   docker build -t openEuler-22.03-LTS-SP4:latest .

4. Start and enter the container.

   Start the container.

   bash

   docker run -itd --privileged openEuler-22.03-LTS-SP4:latest

   Obtain the container ID.

   bash

   docker ps

   Use the container ID to enter the container.

   bash

   docker exec -it CONTAINERID /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: Set the item name to openEuler sysmaster.
   • linux: Change root=/dev/mapper/openeuler-root ro to root=/dev/mapper/openeuler-root rw.
   • linux: if Plymouth is installed in the environment, 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 sysmaster boot item is displayed after the restart, the configuration is successful. Select it to log in to the VM.
