Atomia Agents

Atomia Apache Agent

7 views 0

This manual covers the installation and configuration of the Atomia Apache Agent to enable your customers to work with apache map files.

Before you begin

The Atomia Apache Agent is part of the Atomia agents package. You should start by reading the general package overview and instructions here.

Pre-installation actions

The agent doesn’t require anything special before the installation.

Post-installation actions

In order to properly function, the agent must use root Linux user. So, the first thing to change is the default agent user in the /etc/atomia/config. Open the file and replace atomia-agent with root.

Keep in mind

The default agent user change will force usage of the root Linux user for all agents installed on the server.

One more thing to do is to create and set up the agent’s configuration file. Start by copying the example config file:

sudo cp /etc/atomia/apache-agent.json.example /etc/atomia/apache-agent.json

Edit new copy and change some default properties if needed.

Example file and what each option means:

{
    "auth": {
        "username":"someauthusername",
        "password":"someauthpassword"
    },
    "port": "7000",
    "host": "192.168.33.22",
    "log_path": "/var/log/atomia/apache-agent.log",
    "server_web_root": "/storage/content",
    "vhost_map": "/storage/configuration/maps/vhost.map",
    "users_map": "/storage/configuration/maps/users.map",
    "parking_map": "/storage/configuration/maps/parks.map",
    "redirection_map": "/storage/configuration/maps/redrs.map",
    "frame_redirection_map": "/storage/configuration/maps/frmrs.map",
    "suspended_map": "/storage/configuration/maps/sspnd.map",
    "package_map": "/storage/configuration/maps/packg.map",
    "php_version_map": "/storage/configuration/maps/phpvr.map",
    "proxy_map": "/storage/configuration/maps/proxy.map",
    "ssl_config_dir": "/etc/httpd/ssl.d",
    "ssl_cert_dir": "/storage/content/%%s/%%s/ssl",
    "apachectl_path": "/usr/sbin/apachectl"
}

Changes in the Automation Server

In order to connect the Apache agent with the Atomia provisioning module, the Resource and ProvisioningDescription files should be updated on the server where Atomia Automation Server is installed.

Resource description transformation file

Make sure you have the following resource in the resource file: C:\Program Files (x86)\Atomia\AutomationServer\Common\Resources.xml:

<?xml version="1.0"?>
<resourceDescription xmlns:xdt="http://schemas.microsoft.com/XML-Document-Transform">
    <bindings>
        <moduleList>
            <module name="Atomia.Provisioning.Modules.ApacheRest.Apache" resourceAsignmentPolicy="RoundRobin" />
        </moduleList>
        <resourceList>
            <resource name="Apache">
                <property name="ApacheBaseUrl">http://192.168.33.22:7000</property>
                <property name="Username">someauthusername</property>
                <property name="Password">someauthpassword</property>
                <property name="ClusterIpAddress">192.168.33.22</property>
                <property name="LoadBalancerResourceName">LoadBalancerService_Linux</property>
            </resource>
        </resourceList>
    </bindings>
</resourceDescription>

In the transformation file example above, the ApacheBaseUrl property should match exactly the host and port properties in the apache-agent.json file (as defined in the example at the beginning of this section). Also, the Username and Password properties should be equivalent to the corresponding fields in the auth section of the same config file.

Provisioning description

Make sure that all Apache simple services have REST client set as a providing module. You can do that by placing the following transformation file on the Automation server inside the folder: C:\Program Files (x86)\Atomia\AutomationServer\Common\Resources.xml

<?xml version="1.0" encoding="utf-8"?>
<provisioningDescription xmlns:xdt="http://schemas.microsoft.com/XML-Document-Transform">
	<simpleService providingModule="Atomia.Provisioning.Modules.ApacheRest.Apache" xdt:Locator="XPath(//*[@providingModule='Atomia.Provisioning.Modules.Apache.Apache'])" xdt:Transform="SetAttributes(providingModule)" />
</provisioningDescription>

Running the service

systemctl start atomia-apache-agent
