Installation and Deployment ​

Currently, devmaster can be used in the VM environment. This section describes the requirements and procedure of devmaster installation and deployment.

Software ​

• OS: openEuler 23.09

Hardware ​

• x86_64 or AArch64 architecture

Installation and Deployment ​

1. Run the following yum command to install the sysmaster-devmaster package:

   shell

   # yum install sysmaster-devmaster

2. Run the following commands to create the default rule file /etc/devmaster/rules.d/99-default.rules and the daemon configuration file /etc/devmaster/config.toml:

   shell

   # mkdir -p /etc/devmaster/rules.d
   # mkdir -p /etc/devmaster/network.d
   # echo "TAG+=\"devmaster\"" > /etc/devmaster/rules.d/99-default.rules
   # cat << EOF > /etc/devmaster/config.toml
   log_level = "info"
   rules_d = ["/etc/devmaster/rules.d"]
   network_d = ["/etc/devmaster/network.d"]
   max_workers = 1
   log_targets = ["console"]
   EOF

3. Run the following commands to start the devmaster daemon and export logs to the /tmp/devmaster.log file:

   shell

   # /lib/devmaster/devmaster &>> /tmp/devmaster.log &

   Note:

   devmaster must be started with the root privilege and cannot be running with udev at the same time. Before starting devmaster, stop the udev service.

   If udev is started by sysMaster, run the following command:

   shell

   # sctl stop udevd.service udevd-control.socket udevd-kernel.socket

   If udev is started by systemd, run the following command:

   shell

   # systemctl stop systemd-udevd.service systemd-udevd systemd-udevd-kernel.socket systemd-udevd-control.socket

4. Run the following command to use the devctl tool to trigger a device event:

   shell

   # devctl trigger

5. Check the /run/devmaster/data/ directory. If the device database is generated, the deployment is successful.

   shell

   # ll /run/devmaster/data/
