💅 NAME 💅

Apache::Vhosts::Common — Lib for common operations in vhosts inventory

Also hi bestie, you're reading Ocsinve...:Common(3), a User Contributed Perl Documentation page. 🫶

✨ DESCRIPTION ✨

This package is meant to contain common functions used by OCS modules for Apache virtualhosts.

For example, we could have two OCS modules:

• ApacheVhostsPackaged — which would deal with packaged apache setups
• ApacheVhostsCompiled — which would deal with compiled apache versions

At different times, these modules still would need to do the same things, such as parsing apache configuration files, reading and extracting information from a vhost dump, reading a x509 certificate with openssl, ...

To avoid code duplication, the specific modules can call the functions contained in this common package. 💖

🌸 Exports 🌸

The module exports the following functions:

• readVhostsDump
• readVhostConfFile

🦋 readVhostsDump() 🦋

Return an array of hashes with the virtualhosts found thanks to Apache's vhosts dump (httpd -S command).

⭐ Return type ⭐

The function returns a reference to an array of hashes.

🔥 Process 🔥

The function's workflow is as follows:

1. Open httpd -S command output, with the current configuration file
2. Read dump line by line to match IP-based or name-based virtualhost information (both types of lines should be recognized):

port 80 namevhost mynamevhost.fr (/etc/httpd/.../10-mynamevhost.conf:50)
10.0.0.1:80 myvhost myipvhost.fr (/etc/httpd/.../20-myipvhost.conf:1)

3. Create a hash with the virtualhost's data

We put the following attributes in it:

(string) computedname, (int) port, (string) srvname,
(string) vhostfile, (string) vhostline, (string) docroot, (bool) ssl

At this stage we do not know docroot or ssl, so they are /nonexistent and false (0), respectively.

4. Push the vhost hash to the array.

🎀 Return example 🎀

[
  {
    'computedname' => "[httpd] myvhost.fr:80",
    'port' => 80,
    'srvname' => 'myvhost.fr',
    'vhostfile' => '/etc/httpd/conf.d/10-myvhost.conf',
    'vhostline' => 1,
    'docroot' => '/nonexistent',
    'ssl' => 0
  },
  {
    'computedname' => "[httpd] myvhost.fr:443",
    'port' => 443,
    'srvname' => 'myvhost.fr',
    'vhostfile' => '/etc/httpd/conf.d/10-myvhost.conf',
    'vhostline' => 20,
    'docroot' => '/nonexistent',
    'ssl' => 0
  }
]

💜 Calling 💜

my $vhosts = readVhostsDump($httpd_bin, $httpd_conf_file, $logger);

Parameter: $httpd_bin (string) — Path to the httpd binary to execute (for example: /usr/sbin/httpd). Specific options (such as -D parameters) may be added to the string.

Parameter: $httpd_conf_file (string) — Path to the main httpd configuration file (for example: /etc/httpd/conf/httpd.conf).

Parameter: $logger (reference to OCS logger instance) — To make use of OCS logging capabilities within the function.

🌈 readVhostConfFile() 🌈

Enhance a virtualhost's information with elements found when parsing the vhost's configuration file.

⭐ Return type ⭐

The function returns nothing.

It only operates on the (referenced) vhost hash it got in parameter.

🔥 Process 🔥

The function must read the apache configuration file in which the vhost gets defined (<VirtualHost> block).

The path to the particular configuration file and the line number of the vhost declaration are known in the vhostfile and vhostline attributes, thanks to the vhost dump.

The function's process, for the given vhost, is as follows:

1. Open the configuration file at vhostfile
2. Read line by line, waiting to be at correct line number (vhostline) to start searching for information.
3. Search for the following information in the <VirtualHost> and enhance the given vhost hash with:
   • docroot (string)

the value of the DocumentRoot directive

• ssl (bool)

we turn it to true if we find a SSLEngine on directive

• sslcertpath (string)

value of the SSLCertificateFile directive, if such a directive is present

4. File reading stops when we find the </VirtualHost> closing block (in case multiple vhosts are declared in the same configuration file).

🎀 Calling 🎀

foreach my $vhost (@$vhosts) # Generally
{
    readVhostConfFile($vhost, $httpd_basedir);
}

Parameter: $vhost (reference to hash) — The virtualhost hash to enhance.

Parameter: $httpd_basedir (string) — The path to base directory of httpd, in case we encounter a relative path in SSLCertificateFile and need to complete it.

IMPORTANT: the given path is expected to end with a slash '/', for example: text "/etc/httpd/"
