PHP implements open source SaltStack automated operation and maintenance tool

With the rapid development of the Internet, enterprises’ information construction pays more and more attention to automated operation and maintenance, and they are also constantly exploring various open source automated operation and maintenance tools. Among them, SaltStack is a very good automated operation and maintenance tool, which has the advantages of easy maintenance and rapid deployment, and is widely used in Internet enterprises.

SaltStack is characterized by its distributed architecture, which makes it very easy to deploy, expand and operate. At the same time, SaltStack's language features are also very excellent. It is based on Python and Jinja2 languages. All engines are Python codes, so it is very simple and easy to learn, and the syntax is easier to use than other automation tools.

Here we introduce how to implement open source SaltStack automated operation and maintenance tools through PHP.

First, we need to install SaltStack and prepare the server environment before installation.

1. Install SaltStack

To install SaltStack under Centos or Ubuntu, you can execute the following command:

• Centos system: yum install salt-minion -y

• Ubuntu system: apt-get install salt-minion –y

2. Configure SaltStack

After installation, you need to configure SaltStack, modify the configuration file, and change the minion_id and The ip or domain name where the master is located is set to the id and ip or domain name of the SaltStack Master node we installed.

• 在Centos系统下：

修改/etc/salt/minion文件，将id的值改为SaltStack Master节点的id，
执行service salt-minion restart实现配置生效。

• 在Ubuntu系统下：

修改/etc/salt/minion_id文件，将id的值改为SaltStack Master节点的id，
执行service salt-minion restart实现配置生效。

3. Test SaltStack

After the configuration is completed, you can use the SaltStack Master node to execute instructions to check whether the minion is successfully connected. The specific operations are as follows:

• 在SaltStack Master节点下，执行命令salt ‘*’ test.ping
或者执行命令salt ‘minion_id’ test.ping

• 如果出现True，则表示SaltStack Master节点和minion成功联通。

Next, we Implement SaltStack automated operation and maintenance tools through PHP.

4. PHP implements SaltStack

First, you need to install PHP related extensions, such as cURL and json extensions.

After installation, we can use PHP to connect to the SaltStack API. Once connected to the API, SaltStack commands can be executed using SaltStack's command execution function.

API code example for PHP to connect to SaltStack:

function call_salt_api($api, $params)
{
    $url = 'http://saltapi-url-here:8000/';
    $content = json_encode($params);

    $ch = curl_init();
    curl_setopt($ch, CURLOPT_RETURNTRANSFER, true);
    curl_setopt($ch, CURLOPT_URL, $url . 'run');
    curl_setopt($ch, CURLOPT_POST, true);
    curl_setopt($ch, CURLOPT_POSTFIELDS, $content);
    curl_setopt($ch, CURLOPT_HTTPHEADER, array(
        'Content-Type: application/json',
        'Content-Length: ' . strlen($content)
    ));

    $result = curl_exec($ch);
    curl_close($ch);

    return $result;
}

Code example for PHP to execute SaltStack command:

function call_salt_command($command, $target, $arguments)
{
    $params = array(
        'client' => 'local',
        'tgt' => $target,
        'fun' => $command,
        'arg' => $arguments,
        'expr_form' => 'list'
    );

    $result = json_decode(call_salt_api('run', $params), true);
    if (isset($result['return'][0]))
    {
        return $result['return'][0];
    }

    return false;
}

In the above code example, the API URL is passed to SaltStack Master It is composed of the URL where the node is located and the API port number.

After connecting to the SaltStack API using PHP, we can execute SaltStack commands.

Summary

This article introduces how to implement open source SaltStack automated operation and maintenance tools through PHP. By connecting to the SaltStack API through PHP, we can execute SaltStack commands in PHP to achieve automated operation and maintenance.

For enterprises that need to realize automated operation and maintenance, SaltStack is a very good automated operation and maintenance tool that can reduce operation and maintenance costs and improve efficiency. Through this article, readers can better understand how to use PHP to implement open source SaltStack automated operation and maintenance tools, and hope to bring some help to readers in actual work.
