Installing Gearman on FreeBSD Latest

Gearman is an open source, distributed job-processing system that enables users to offload tasks to multiple servers. Here is a step-by-step tutorial on how to install Gearman on FreeBSD Latest.

Prerequisites

Before you begin installing Gearman, it is essential to ensure that your FreeBSD system is updated to the latest version.

Install Gearman

To install Gearman, follow the steps below.

1. Open the terminal and enter the following command to install the Gearman daemon:

pkg install gearmand

2. Once Gearman is installed, you need to start the daemon. To start the daemon, enter the following command:

service gearmand start

3. By default, Gearman listens on localhost port 4730. To confirm that the daemon is running, enter the following command:

netstat -an | grep 4730

You should see a similar output to the one below:

tcp4       0      0  127.0.0.1.4730         *.*                    LISTEN

4. To ensure that Gearman starts automatically at boot time, run the following command:

echo 'gearmand_enable="YES"' >> /etc/rc.conf

Install PHP extension for Gearman

If you are using PHP, you can leverage Gearman's power by installing the PHP extension for Gearman. Here’s how:

1. Open the terminal and enter the following command:

pkg install php74-pecl-gearman

2. Once the PHP extension is installed, you need to add it to the PHP configuration file. To do this, edit the file /usr/local/etc/php.ini and add the following line at the end of the file:

extension=gearman.so

3. Now, you can test the PHP extension by creating a simple Gearman client script. Here’s an example:

<?php

$client= new GearmanClient();
$client->addServer('127.0.0.1', 4730);
echo $client->do("reverse", "Hello World!");

?>

This script will send the string "Hello World!" to the Gearman daemon and reverse it. The output should be "dlroW olleH".

Conclusion

Congratulations! You have successfully installed Gearman on FreeBSD Latest and set up the PHP extension for Gearman. Gearman can improve the performance and scalability of your application by enabling you to distribute tasks across multiple servers.
