Gearman is a powerful job server that allows you to distribute work to other machines or processes in a distributed environment. In this tutorial, we will guide you on how to install Gearman on OpenBSD.
Before we proceed with the installation, you should ensure that your OpenBSD system is up-to-date. To do that, run the following command as the root user:
pkg_add -u
pkg_add gearmand gearman-tools
rcctl start gearmand
rcctl check gearmand
You should see output indicating that the server is running.
By default, Gearman listens on port 4730. You can change this port number by editing the configuration file located at /etc/gearmand.conf.
For example, to change the port to 12345, edit the file and change the listen directive as follows:
listen=127.0.0.1:12345
Save the file and restart the Gearman server:
rcctl restart gearmand
Now that Gearman is installed and running, you can start using it for your distributed jobs. You can create clients and workers using the gearman command-line tool.
To create a job client, use the gearman command followed by the --client option and the name of the job server. For example:
gearman --client=localhost:12345 echo "Hello, Gearman!"
To create a job worker, use the gearman command followed by the --worker option and the name of the job server. For example:
gearman --worker=localhost:12345 reverse_string
When the worker job is created, it will wait for a job from the job server. Once a job is received, the worker will execute the job and return the result to the job server.
Congratulations! You have successfully installed Gearman on OpenBSD. You can now start using Gearman for your distributed jobs.
If you want to self-host in an easy, hands free way, need an external IP address, or simply want your data in your own hands, give IPv6.rs a try!
Alternatively, for the best virtual desktop, try Shells!
