The page aimed for server's infrastructure of OpenSCADA project representing, tracing and managing.

From the OpenSCADA founding its resources were hosted on a main server of [http://diyaorg.dp.ua DIYA Ltd] and the server details and specific were not suitable to publish. From year 2015 the OpenSCADA project have got an own server and an internet channel thanks mostly to [http://e-beam.ru Beams&Plasmas] [http://oscada.org/en/development/tasks/posts/tasks_forming_formirovanie_zadach/the_project_server_and_hosting_infrastructure_update funding]. From year 2016 all resources of the project OpenSCADA were moved to the new server, the domain name "oscada.org" was switched to it and as its DNS there used [http://ukraine.com.ua the Hosting Ukraine] with configuration in Table 1.

'''Table 1:''' Domain "oscada.org" configuration.

== Hardware and the Internet channel ==
The OpenSCADA server is located now in a quarter of the OpenSCADA author. To connect the global network there is used one of the Internet service providers in Kamjanske city of Ukraine. The provider uses the conception of Fiber To The Building (FTTB) and the Internet channel bandwidth now is 50Mbit/s. The main domain-name "oscada.org" is connected now to the static IP '''46.98.2.159'''. Hardware configuration of the server is shown in Table 2.

== Environment of the programs and services ==
The program environment uses in common the OS [http://kernel.org Linux] distribution [http://debian.org Debian] 7 (Wheezy). For external services isolation and some other purposes there used the [http://openvz.org OpenVZ] lightweight isolation in different Virtual Private Servers (VPS). In the most VPSes there used also the Linux distributive Debian 7 (Wheezy), sometime there used Debian 8 (Jessie) and ALTLinux T6. The hardware server (HS) is the x86_64 program environment though the VPSes use mostly the x86_32 environment especially in the demanding tasks, as the result of that we have overall memory consumption of the server about 1.2GB instead 2GB of an even-functional x86_64 pure environment. The program environment structure shown in Figure 1.

[[File:Server_net.png|center|frame|Figure 1. Network of the OpenSCADA server and structure of the program environment.]]

File system of the hardware server (HS) has no swap partition and has two main mirrored partitions:
* "root (/)": 9.1GB
* "data (/data): 908GB

Besides management by OpenVZ for the VPS containers, the HS environment contains also some services for external and internal networks:
* '''SSH''': Generic access to the server control by SSH from internal and external environments.
* '''PPTP''': Secure tunnelling for connection from external environments to the internal network or for back remote connection to the connected clients.
* '''NTP''': Network time service for internal and external hosts.
* '''FTP''': FTP-server of the internal network for accessing the local data storage.
* '''Samba''': SMB-server of the internal network for accessing the local data storage.
* '''[http://oscada.org:3142 AptCacher]''' (DISABLED): APT-cacher of the new generation '''apt-cacher-ng''', serves for unmistakable Live Disks building and used in the Debian systems updating by http-cacher.
:Service config files: "/etc/apt-cacher-ng/".
* '''AptMirror''' (DISABLED): APT mirroring '''apt-mirror''' for needs of the APT-repositories, serves for unmistakable Live Disks building in the TDE using.
* '''[http://oscada.org/en/development/tasks/posts/core/the_automatic_openscada_builder AutoBuilder]''': Automatic OpenSCADA package's builder for LTS and Work branches of OpenSCADA, with checking the local Subversion repository.
* '''DNS (Bind9)''': Server of the domain names of the internal network.
* '''DHCP''': Hosts' dynamic configuration of the internal network.
* '''[http://oscada:631 CUPS]''': Print service of the internal network.
* '''[http://oscada:10002 SmartHouse]''': Smart House and sensors monitoring of the server, based on OpenSCADA.

=== VPS: [http://oscada.org/svn SVN] ===
'''''Address:''''' svn.oscada (192.168.0.12) 
'''''Service:''''' provides the version control systems 
'''''Base of the VPS:''''' OS Linux distributive Debian 7 (Wheezy) x86, provides the version control systems: Subversion, CVS

CVS is an deprecated version control system used up to year 2005 by the OpenSCADA project and some projects of the firm [http://diyaorg.dp.ua DIYA Ltd] of their author [[User:RomanSavochenko|Roman Savochenko]]. Currently CVS is provided only for the compatibility and that supports only the guest access {{InLineCode|<nowiki>cvs -d:pserver:guest@oscada.org:/CVS_R co OpenScada</nowiki>}}.

Subversion is the actual version control system used now by the OpenSCADA project. It supports two managing and two display connections:
* in the classic way it allows managing and anonymous reading/observing by own service "'''svn://'''", for example {{InLineCode|<nowiki>svn ls svn://oscada.org/trunk/OpenSCADA/</nowiki>}};
* in the secure way by SSH it allows managing only for the authorized users by the secure prefix "'''svn+oscada://'''", for example {{InLineCode|<nowiki>svn ls svn+oscada://oscada.org/mnt/SVN_R/trunk/OpenSCADA</nowiki>}};
* through DAV by HTTP it allows only anonymous reading/observing by the HTTP prefix "'''http://'''", for example {{InLineCode|<nowiki>svn ls http://oscada.org/svn/trunk/OpenSCADA/</nowiki>}};
* through the Web-interface of WebSVN it allows only [http://oscada.org/websvn the anonymous observing]

=== VPS: HTTP ===
'''''Address:''''' http.oscada (192.168.0.13) 
'''''Service:''''' provides different HTTP-services which mostly based on the [http://httpd.apache.org Apache2] Web Server 
'''''Base of the VPS:''''' OS Linux distributive Debian 7 (Wheezy) x86, Apache Web Server

Main configuration file of the virtual hosts placed in "/etc/apache2/sites-available/openscada.conf". EMail was configured in "/etc/postfix/main.cf" as a simple relay to the [[#EMail|EMail server VPS]].

http://oscada.org/typo3
| Main site of the project OpenSCADA based on the [http://typo3.org CMS "TYPO3"], including the CMS admin WEB-Interface. || Placed in "/var/www/oscada/".

This configuration and DB moved from PHP version 5.2 to 5.4 and from TYPO3 version 4.3 to 4.5 LTS. In that reason and since PHP 5.4 has significant changes there were some migrations problems in the CMS extensions mm_forum, sr_feuser_register and lz_gallery, which fixed.

Commands of migration of the DB:
<syntaxhighlight lang="bash">
mysqldump -Q --user=web -p t3_oscada > t3_oscada.sql
mysql --default-character-set=utf8 --user=web -p t3_oscada < ./t3_oscada.sql
</syntaxhighlight>
Fixed bugs:
* [2021-10-14] The module "sr_feuser_register" finished in translation to Ukrainian, FE appended by the users invitation page for developers and contributors, and enabled for the administrator review of the new registrants.
* [2016-11-19] Long entry to the FE login at an error in the last part of addLabelMarkers(). Long entry to the BE login at array trim() in TYPO3 cObjGetSingle(), replaced to:
<syntaxhighlight lang="PHP" style="margin-left: 30px">
if(is_array($name)) array_walk($name, 'trim');
else $name = trim($name);</syntaxhighlight>
* [2016-04-30] The module "mm_forum" omits to encode for the "quoted-printable" mode at all that causes for message headers like to "XXXX", possible in class.tx_mmforum_havealook.php.
* [2016-04-30] The EMail encoding by the "quoted-printable" mode some broken, especially for the header sequences like to "(а)", the module "sr_feuser_register".

http://wiki.oscada.org
| Old knowledge base (WIKI) of the OpenSCADA project on [http://wackowiki.sourceforge.net/ WackoWIKI] || Placed in "/var/www/oscada/wacko/".

This configuration and DB moved from PHP version 5.2 to 5.4 what caused for some problems, firstly it is in the function htmlspecialchars() and need in the default charset UTF-8. These problems mostly fixed before moving to the new Wiki-engine.

Commands of migration of the DB:
<syntaxhighlight lang="bash">
