Bitrix24 On-Premise Server Installation: Detailed Guide

Recently, a client decided to migrate Bitrix24 from the cloud to their own server. At the installation stage, they encountered a MySQL error: tables were not created due to incorrect encoding. Agents did not start because cron was missing, push notifications were silent—the daemon was not running. We fixed everything in one day. Such situations are our routine. Over years of experience, we have installed on-premise Bitrix24 on 50+ servers and know every pitfall. Each project is unique, but key issues recur: wrong file permissions, misconfigured nginx, missed MySQL setup step. A clear plan and understanding of the platform's internals help avoid them.

How to Install Bitrix24 On-Premise on a Server Correctly

Proper installation of Bitrix24 On-Premise is not just unpacking an archive. It involves configuring the server environment, database, web server, and background processes. The result is stable operation without failures even under peak loads.

Server Requirements

OS: Ubuntu 20.04/22.04 LTS (recommended) or CentOS 7/8. PHP 8.0–8.2, MySQL 5.7/MariaDB 10.4+, Nginx 1.18+ + PHP-FPM. PostgreSQL is not supported.

BitrixVM or Manual Installation: Which to Choose?

BitrixVM is a ready-made virtual machine image (Vagrant box or VMware/VirtualBox) with pre-installed nginx, php-fpm, MySQL. It is ideal for quick start but offers little flexibility. Manual installation provides full control over configuration. Official installer bitrixsetup.php: run wget https://www.1c-bitrix.ru/download/bitrix24_eshop.tar.gz, unpack, open /bitrixsetup.php in browser. Before running, configure php.ini:

memory_limit = 256M
upload_max_filesize = 100M
post_max_size = 100M
max_execution_time = 300
opcache.enable = 1
opcache.memory_consumption = 128

According to official 1C-Bitrix documentation, a properly configured server with 8 cores and 16 GB RAM serves up to 500 users without performance loss.

How to Configure MySQL and nginx for Load?

Create database and user:

CREATE DATABASE bitrix24 CHARACTER SET utf8mb4 COLLATE utf8mb4_unicode_ci;
CREATE USER 'bitrix'@'localhost' IDENTIFIED BY 'strongpassword';
GRANT ALL PRIVILEGES ON bitrix24.* TO 'bitrix'@'localhost';
FLUSH PRIVILEGES;

In my.cnf add:

innodb_buffer_pool_size = 2G  # 50-70% of RAM
innodb_log_file_size = 256M
query_cache_size = 0          # disable in MySQL 8
max_connections = 200

nginx configuration is critical—standard Laravel/WordPress setups do not work. Key blocks:

location / {
    try_files $uri $uri/ @bitrix;
}

location @bitrix {
    fastcgi_pass php-fpm;
    include fastcgi_params;
    fastcgi_param SCRIPT_FILENAME $document_root/bitrix/urlrewrite.php;
}

location ~* ^/bitrix/admin {
    allow 10.0.0.0/8;
    deny all;
}

More details in official nginx setup documentation. Without specific URL rules, pages will not load.

How to Start Agents and Push Server?

After the setup wizard, you must:

1. Configure cron: add a task to run /bitrix/cron_events.php every minute.
2. Start the push server—a separate daemon for chat and notifications. Configuration in push-server/nginx/nginx.conf. Instructions at helpdesk.bitrix24.ru.
3. Set up mail (Settings → Mail), otherwise invitation emails will not be sent.
4. Install SSL—via Let's Encrypt or self-signed certificate.

A common post-installation error is incorrect file permissions. After installation, files often belong to root while php-fpm runs as www-data. Fix:

chown -R www-data:www-data /var/www/html
find /var/www/html -type d -exec chmod 755 {} \;
find /var/www/html -type f -exec chmod 644 {} \;
chmod -R 775 /var/www/html/upload /var/www/html/bitrix/cache

Also configure tagged caching—this reduces MySQL load by a factor of 2–3.

Why On-Premise Is Better Than Cloud?

On-Premise gives you full control over data and updates. You do not share resources with other tenants during peak loads. The cost savings compared to the cloud version over three years can be substantial. For companies with strict security requirements, it is the only option. Moving to your own infrastructure pays off within 6–8 months of active use.

Why Trust Professionals with Installation?

Improper installation leads to slow performance, agent failures, and data leaks. Our years of experience allow us to avoid these issues. With us, you get a production-ready system with stability guarantee. Get a consultation—we will find the optimal configuration for your budget and load.

What Professional 1C-Bitrix Installation Includes

We start by checking innodb_buffer_pool_size. The default MySQL value (128 MB) is a death sentence for an online store with a catalog of 10,000+ items. We set 70–80% of available RAM on a dedicated server, 50% on VPS. This single setting speeds up the site by 2–3 times compared to the default. We'll assess your project in one day — get a consultation. Contact us to order turnkey installation with performance guarantee.

How to Choose Hosting and Edition for 1C-Bitrix Installation?

BitrixVM is a virtual machine with a pre-installed stack: nginx + Apache, PHP-FPM, MySQL/MariaDB, Sphinx, Push server. For VPS — the best start. Everything is already configured for Bitrix, including OPcache, log rotation, and firewall. Management via web panel on port 8890. Bitrix documentation recommends starting with BitrixVM for predictable performance.

VPS/VDS is the sweet spot. Minimum configuration for a medium online store: 2 vCPU, 4 GB RAM, SSD. Optimal: 4 vCPU, 8 GB RAM. OS: Ubuntu 22.04 or Debian 12. If not BitrixVM, we configure the stack manually for the task. Virtual hosting — only for business cards and landing pages. Requirements: PHP 8.0+, MySQL 5.7+ / MariaDB 10.0+, 512 MB RAM, .htaccess. 1C-Bitrix hosting partners guarantee compatibility. Dedicated server — for highload. Typical architecture: web server separate, database separate, Redis/Memcached separate. For Enterprise edition — web cluster with load balancer. Cloud (Yandex Cloud, VK Cloud, Selectel) — when load spikes: sales, seasonal peaks. Autoscaling via Managed Kubernetes or simple VM vertical scaling.

Choosing the edition is equally important. A common mistake: choosing "Small Business" for a store that grows to B2B with wholesale prices and three warehouses in six months. Upgrading to "Business" — pay the difference, data is not lost, but it's better to plan ahead. Our specialists select the edition for current tasks and with room for growth. For example, the "Business" license (about 35,000 RUB) pays off through multi-warehouse and 1C exchange, while the wrong choice can lead to a loss of up to 30,000 RUB monthly on excess resources.

What Server Settings Are Critical for 1C-Bitrix?

Web Server and PHP

nginx as reverse proxy + Apache (mod_php) or nginx + PHP-FPM directly. The second option saves memory — Apache is not needed. But some Bitrix modules use .htaccess, so for compatibility we sometimes keep Apache. nginx configuration: fastcgi_read_timeout 300 — for long operations (1C import), client_max_body_size 1024m — large file uploads. Block access to .settings.php, .settings_extra.php, bitrix/.settings.php — they contain database passwords. Rewrite rules from urlrewrite.php — Bitrix generates them, but with nginx + PHP-FPM they need to be duplicated. PHP 8.0–8.2 with extensions: mbstring, curl, gd, xml, json, opcache, redis/memcached. Key php.ini settings: opcache.memory_consumption=256, opcache.max_accelerated_files=20000, max_execution_time=300, memory_limit=512M, upload_max_filesize=100M, post_max_size=128M.

Database and Caching

MySQL/MariaDB. Key my.cnf parameters: innodb_buffer_pool_size — 70–80% RAM, innodb_log_file_size=256M, tmp_table_size=256M, max_heap_table_size=256M, thread_pool_size — number of CPU cores. Encoding utf8mb4 mandatory, otherwise emoji and special characters break. Redis is preferable to Memcached for Bitrix — supports persistent connections and is more reliable. In production, Redis handles concurrent writes three times faster than Memcached under typical load. Configure in .settings_extra.php:

'cache' => ['value' => ['type' => ['class_name' => '\\Bitrix\\Main\\Data\\CacheEngineRedis']]]
'session' => ['value' => ['mode' => 'default', 'handlers' => ['general' => ['type' => 'redis']]]]

sudo apt install redis-server
sudo systemctl enable redis

SSL, Email, and Cron

SSL — Let's Encrypt via certbot in 90% of cases. Redirect HTTP → HTTPS (301), HSTS, TLS 1.2/1.3, OCSP Stapling. In Bitrix, switch to HTTPS in the main module settings. Email: abandon mail() — connect SMTP (Yandex.Mail for domain, Mail.ru for Business). Be sure to configure SPF, DKIM, DMARC. Without SPF, emails go to spam. Test deliverability via mail-tester.com — score 9+/10. Cron: Bitrix agents switch to system cron — * * * * * /usr/bin/php /var/www/bitrix/modules/main/tools/cron_events.php. Schedule 1C exchange (15–60 min), search reindex, backups (mysqldump + rsync, rotation 7+4), temporary file cleanup.

Security and Administration

File system: owner www-data, directories 755, files 644, upload 775. nginx blocks access to configuration files. Enable Bitrix Proactive Protection — WAF, activity control (block after 5 failed attempts), kernel integrity check. For admin panel: two-factor authentication via Google Authenticator or OTP, restrict access by IP via nginx for paranoid.

How Long Does 1C-Bitrix Installation and Configuration Take?

Post-Installation Checklist

1. Performance Monitor (/bitrix/admin/perfmon_panel.php) — aim for 30+ points. Below 20 means serious configuration issues.
2. System Check — automatic check of all parameters. Red items must be fixed, yellow — case by case.
3. Security Scanner — check for typical vulnerabilities.
4. PageSpeed Insights — TTFB < 200ms on VPS, LCP < 2.5s.
5. Test 1C exchange — if integration is planned, verify CommerceML exchange before launch.

Additionally, check software versions, caching settings, cron operation, SSL certificate, SPF/DKIM/DMARC, access rights, delete default users and pages. For projects with 54-FZ, ensure fiscalization is configured via OFD provider.

Why Trust Professionals with Installation?

Incorrect installation means lost time and money. We've seen projects where a store on "Start" couldn't handle 50 visitors because innodb_buffer_pool_size wasn't configured. After migrating to VPS with correct configuration, the site "flew". Incorrect configuration can cost 30,000 RUB monthly due to excessive resource consumption.
