Nginx/ru

nginx is a robust, small, high performance web server and reverse proxy server. It is a good alternative to popular web servers like Apache and lighttpd.

Установка
Перед непосредственной установкой пакета, сначала прочитайте про USE флаги для Nginx.

Expanded USE flags
Nginx uses modules to enhance its features. To simplify the maintenance of this modular approach, the nginx ebuild uses expanded USE flags to denote which modules should be installed.


 * HTTP related modules can be enabled through the  variable
 * Mail related modules can be enabled through the  variable
 * Third party modules can be enabled through the  variable

These variables need to be set in. Their descriptions can be found in and.

For example, to enable the  module:

Emerge
With the USE flags set, install :

Installation verification
The nginx package installs a init service script allowing administrators to stop, start, or restart the service. Run the next command to start the nginx service:

To verify that nginx is properly running, point a web browser to the http://localhost address or use a command-line web tool like curl:

Настройка
Конфигурация nginx находится в файле.

Доступ к одному сайту
Следующий пример показывает конфигурацию для доступа к одному сайту без динамических возможностей (таких как PHP).

Multiple site access
It is possible to leverage the  directive to split the configuration in multiple files:

PHP support
Добавьте следующие строки в конфигурацию nginx для включения поддержки PHP. В данном примере nginx обменивается информацией с процессом PHP через сокет UNIX.

Для поддержки такой настройки, PHP нужно собрать с поддержкой менеджера процессов FastCGI (php-fpm), что обрабатывается через USE флаг :

Rebuild PHP with the  USE flag enabled:

Review the configuration and add following line:

Set the timezone in the php-fpm file. Substitute the  text in the FileBox below with the appropriate timezone information:

Start the php-fpm daemon:

Add php-fpm to the default runlevel:

Reload nginx with changed configuration:

IP address access list
The next example shows how to allow access to a particular URL (in this case /nginx_status) only to
 * certain hosts (e.g. 192.0.2.1 127.0.0.1)
 * and IP networks (e.g. 198.51.100.0/24)

Basic authentication
nginx allows limiting access to resources by validating the user name and password:

The file can be generated using:

TLS support
It is warmly suggested to support only TLS and disable known insecure ciphers.

The ebuild provides stock self signed certificates in

Forward secrecy
The diffie-hellman certificate can be created using openssl:

Third party modules
Download third party module source and move it to. Manually compile the selected Nginx module, then add the following line to :

Rebuild nginx with the third party module enabled:

OpenRC
Start nginx:

Stop nginx:

Add nginx to the default runlevel:

Restart the nginx service:

Troubleshooting
In case of problems, the following commands can help troubleshoot the situation.

Validate configuration
Verify that the running nginx configuration has no errors:

By running nginx with the  option, it will validate the configuration file without actually starting the nginx daemon.

Verify processes are running
Check if nginx processes are running:

Verify bound addresses and ports
Verify nginx daemon is listening on the right TCP port (such as 80 for HTTP or 443 for HTTPS):
