PHP Library for NGINX configuration parser/generator
This library can parse and generate NGINX configuration files. In near future will provide CLI commands for NGINX configuration.
Install with Composer
composer require madkom/nginx-configurator
This library requires PHP in ~7 version.
Parsing configuration string:
use Madkom\NginxConfigurator\Builder;
use Madkom\NginxConfigurator\Config\Server;
use Madkom\NginxConfigurator\Parser;
require 'vendor/autoload.php';
$config = <<<CONFIG
server {
listen 8080;
root /data/www/web;
index index.php index.html index.htm;
location / {
try_files $uri $uri/ /index.php;
}
error_page 404 /404.html;
error_page 500 502 503 504 /50x.html;
location = /50x.html {
root /usr/share/nginx/www;
}
# pass the PHP scripts to FastCGI server listening on the php-fpm socket
location ~ \.php$ {
try_files $uri =404;
fastcgi_pass unix:/var/run/php5-fpm.sock;
fastcgi_index index.php;
fastcgi_param SCRIPT_FILENAME $document_root$fastcgi_script_name;
include fastcgi_params;
}
}
CONFIG;
$parser = new Parser();
$defaultConfig = $parser->parse($config);
/** @var Server $defaultServers[] */
$defaultServers = $defaultConfig->search(function (Node $node) {
return $node instanceof Server;
});
$builder = new Builder();
if (count($defaultServers) > 0) {
/** @var Server $defaultServer */
foreach ($defaultServers as $defaultServer) {
$builder->append($defaultServer);
}
}Generating configuration string:
use Madkom\NginxConfigurator\Factory;
use Madkom\NginxConfigurator\Builder;
use Madkom\NginxConfigurator\Config\Location;
use Madkom\NginxConfigurator\Node\Directive;
use Madkom\NginxConfigurator\Node\Literal;
use Madkom\NginxConfigurator\Node\Param;
require __DIR__ . '/../vendor/autoload.php';
$factory = new Factory()
$builder = new Builder();
$server = $builder->append($factory->createServer(80));
$server->append(new Directive('error_log', [
new Param('/var/log/nginx/error.log'),
new Param('debug'),
]));
$server->append(new Location(new Param('/test'), null, [
new Directive('error_page', [new Param('401'), new Param('@unauthorized')]),
new Directive('set', [new Param('$auth_user'), new Literal('none')]),
new Directive('auth_request', [new Param('/auth')]),
new Directive('proxy_pass', [new Param('http://test-service')]),
]));
$server->append(new Location(new Param('/auth'), null, [
new Directive('proxy_pass', [new Param('http://auth-service:9999')]),
new Directive('proxy_bind', [new Param('$server_addr')]),
new Directive('proxy_redirect', [new Param('http://$host'), new Param('https://$host')]),
new Directive('proxy_set_header', [new Param('Content-Length'), new Literal("")]),
new Directive('proxy_pass_request_body', [new Param('off')]),
]));
$server->append(new Location(new Param('@unauthorized'), null, [
new Directive('return', [new Param('302'), new Param('/login?backurl=$request_uri')]),
]));
$server->append(new Location(new Param('/login'), null, [
new Directive('expires', [new Param('-1')]),
new Directive('proxy_pass', [new Param('http://identity-provider-service')]),
new Directive('proxy_bind', [new Param('$server_addr')]),
new Directive('proxy_redirect', [new Param('http://$host'), new Param('https://$host')]),
new Directive('proxy_set_header', [new Param('Content-Length'), new Literal("")]),
new Directive('proxy_pass_request_body', [new Param('off')]),
]));
print($builder->dump());Generated configuration output:
server {
listen 80;
listen [::]:80 default ipv6only=on;
error_log /var/log/nginx/error.log debug;
location /test {
error_page 401 @unauthorized;
set $auth_user "none";
auth_request /auth;
proxy_pass http://test-service;
}
location /auth {
proxy_pass http://auth-service:9999;
proxy_bind $server_addr;
proxy_redirect http://$host https://$host;
proxy_set_header Content-Length "";
proxy_pass_request_body off;
}
location @unauthorized {
return 302 /login?backurl=$request_uri;
}
location /login {
expires -1;
proxy_pass http://identity-provider-service;
proxy_bind $server_addr;
proxy_redirect http://$host https://$host;
proxy_set_header Content-Length "";
proxy_pass_request_body off;
}
}
There are also methods to read and dump file:
use Madkom\NginxConfigurator\Builder;
use Madkom\NginxConfigurator\Config\Location;
use Madkom\NginxConfigurator\Config\Server;
use Madkom\NginxConfigurator\Node\Directive;
use Madkom\NginxConfigurator\Node\Literal;
use Madkom\NginxConfigurator\Parser;
require __DIR__ . '/../vendor/autoload.php';
$parser = new Parser();
$builder = new Builder();
$configuration = $parser->parseFile('default.conf');
/** @var Server $servers[] */
$servers = $configuration->search(function (Node $node) {
return $node instanceof Server;
});
if (count($servers) > 0) {
/** @var Server $server */
foreach ($servers as $server) {
$builder->append($server);
}
}
$builder->dumpFile('generated.conf');- Implement comments parsing
- Implement commands for config manipulation from CLI
