<p class="p_Normal">The architecture of the highly available BRIX cluster involves the interaction of BRIX application microservices with a PostgreSQL database cluster. To ensure secure load balancing in the system, create a HAProxy configuration for PostgreSQL. This way, in case of a failure, all traffic will be redirected to the Master-Replica(s) cluster, which guarantees continuous operation of the system.</p>
|
||||
<p class="p_Normal">Examples of a HAProxy сonfiguration:</p>
|
||||
<p class="p_Normal">Архитектура высокодоступного кластера ELMA365 подразумевает взаимодействие микросервисов приложения ELMA365 с кластером базы данных PostgreSQL. Чтобы обеспечить надёжную балансировку нагрузки в системе, создайте конфигурацию HAProxy для PostgreSQL. Так, в случае сбоя весь трафик будет перенаправлен в кластер Master-Replica(s), что гарантирует непрерывную работу системы.</p>
|
||||
<p class="p_Normal">Примеры настройки HAProxy:</p>
|
||||

||||
<li value="1" class="p_Normal"><a href="haproxy-postgresql.html#haproxypostgresql" class="topiclink">Example HAProxy configuration for connecting to PostgreSQL</a>.</li><li value="2" class="p_Normal"><a href="haproxy-postgresql.html#haproxypgbouncer" class="topiclink">Example HAProxy configuration for connecting to PGBouncer</a>.</li></ol>
|
||||
<h2 class="p_Heading2"><a id="haproxypostgresql" class="hmanchor"></a><span class="f_Heading2">Example of a HAProxy configuration for connecting to PostgreSQL</span></h2>
|
||||
<p class="p_Normal">This configuration is prepared for load balancing traffic in a PostgreSQL cluster deployed according to the description in <a href="configure-postgresql.html" class="topiclink">PostgreSQL cluster</a>. HAProxy is used for balancing. It automatically checks port <code><b>8008</b></code> of Patroni service on PostgreSQL servers with the <code><b>master</b></code> role.</p>
|
||||
<p class="p_Normal">The operation traffic to the cluster is distributed as follows:</p>
|
||||
<li value="1" class="p_Normal"><a href="haproxy-postgresql.html#haproxypostgresql" class="topiclink">Пример конфигураци HAProxy для подключения к PostgreSQL</a>.</li><li value="2" class="p_Normal"><a href="haproxy-postgresql.html#haproxypgbouncer" class="topiclink">Пример конфигураци HAProxy для подключения к PGBouncer</a>.</li></ol>
|
||||
<h2 class="p_Heading2"><a id="haproxypostgresql" class="hmanchor"></a><span class="f_Heading2">Пример конфигурации HAProxy для подключения к PostgreSQL</span></h2>
|
||||
<p class="p_Normal">В этой статье конфигурация подготовлена для балансировки трафика в кластер PostgreSQL, развёрнутый согласно описанию из статьи <a href="configure-postgresql.html" class="topiclink">«Кластер PostgreSQL»</a>. Для балансировки используется HAProxy. С его помощью автоматически проверяется порт <code><b>8008</b></code> сервиса Patroni на серверах PostgreSQL с ролью <code><b>master</b></code>.</p>
|
||||
<p style="margin: 7px 0 16px 0;">Трафик операций в кластер распределяется следующим образом:</p>
|
||||
<ul style="list-style-type:disc">
|
||||
<li class="p_Normal">Write operations coming to <code><b>haproxy-server.your_domain:5000</b></code> are directed to the server with the <code><b>master</b></code> role.</li><li class="p_Normal">Read operations coming to <code><b>haproxy-server.your_domain:5001</b></code> are directed to servers with the <code><b>slave</b></code> role.</li></ul>
|
||||
<p class="p_Normal">In case of a failure, all traffic will be redirected to the Master-Replica(s) cluster, i.e. write and read operations will start to arrive here.</p>
|
||||
<p class="p_Normal">In order to create a HAProxy configuration for PostgreSQL, follow these steps:</p>
|
||||
<li class="p_Normal">операции записи, приходящие на <code><b>haproxy-server.your_domain:5000</b></code>, направляются на сервер с ролью <code><b>master</b></code>;</li><li class="p_Normal">операции чтения, приходящие на <code><b>haproxy-server.your_domain:5001</b></code>, направляются на сервера с ролью <code><b>slave</b></code>.</li></ul>
|
||||
<p style="margin: 7px 0 16px 0;">В случае сбоя весь трафик будет перенаправлен в кластер Master-Replica(s), т. е. операции записи и чтения начнут поступать именно сюда.</p>
|
||||
<p style="margin: 7px 0 7px 0;">Чтобы создать конфигурацию HAProxy для PostgreSQL выполните следующие действия:</p>
|
||||
<ol style="list-style-type:upper-roman">
|

<li value="1" class="p_Normal">Open the <code><b>haproxy.cfg</b></code> configuration file for editing using the following command:</li></ol>

HAProxy is used for balancing. It automatically checks port <code><b>8008</b></code> of Patroni service on PostgreSQL servers with the <code><b>master</b></code> role.</p>

<h2 class="p_Heading2"><a id="haproxypgbouncer" class="hmanchor"></a><span class="f_Heading2">Пример конфигураци HAProxy для подключения к PGBouncer</span></h2>
|
||||
<p class="p_Normal">В этой статье представлена конфигурация для балансировки трафика в кластер PostgreSQL, развёрнутый согласно описанию из статьи <a href="configure-postgresql.html" class="topiclink">«Кластер PostgreSQL»</a>, через программу <a href="pgbouncer-installation.html" class="topiclink">PGBouncer</a>. Для балансировки используется HAProxy. С его помощью автоматически проверяется порт <code><b>8008</b></code> сервиса Patroni на серверах PostgreSQL с ролью <code><b>master</b></code>.</p>
|
||||
<p style="margin: 7px 0 16px 0;">Трафик операций в кластер распределяется следующим образом:</p>
|
||||
<ul style="list-style-type:disc">
|
||||
<li class="p_Normal">Write operations coming to <code><b>haproxy-server.your_domain:5000</b></code> are directed to the server with the <code><b>master</b></code> role.</li><li class="p_Normal">Read operations coming to <code><b>haproxy-server.your_domain:5001</b></code> are directed to servers with the <code><b>slave</b></code> role.</li></ul>
|
||||
<p class="p_Normal">In case of a failure, all traffic will be redirected to the Master-Replica(s) cluster, i.e. write and read operations will start to arrive here.</p>
|
||||
<p class="p_Normal">In order to create a HAProxy configuration through the PGBouncer program, perform the following actions:</p>
|
||||
<li class="p_Normal">операции записи, приходящие на <code><b>haproxy-server.your_domain:5000</b></code>, направляются на сервер с ролью <code><b>master</b></code>;</li><li class="p_Normal">операции чтения, приходящие на <code><b>haproxy-server.your_domain:5001</b></code>, направляются на сервера с ролью <code><b>slave</b></code>.</li></ul>
|
||||
<p style="margin: 7px 0 16px 0;">В случае сбоя весь трафик будет перенаправлен в кластер Master-Replica(s), т. е. операции записи и чтения начнут поступать именно сюда.</p>
|
||||
<p style="margin: 7px 0 7px 0;">Чтобы создать конфигурацию HAProxy для PostgreSQL через программу PGBouncer выполните следующие действия:</p>
