Nginx代理访问RabbitMQ Management UI

RabbitMQ官方文档说明如下：

Using a Reverse Proxy in front of the HTTP API

It may be necessary to put a reverse proxy in front of a RabbitMQ cluster. Reverse proxy setup for RabbitMQ may require careful handling of encoded slashes in paths if default virtual host (/) is used.

If default virtual host is not used, the additional settings to support encoded URIs will not be necessary. In other words, both Nginx and Apache configuration will require the standard minimum for any HTTP-based service.

Nginx

If RabbitMQ HTTP API access is configured for the root location (/), the location must not have a slash at the end:

# trailing slash in the location must be omitted only if default RabbitMQ virtual host is used
location / {
    proxy_pass http://rabbitmq-host:15672;
}

If a different location will be used to proxy requests to the HTTP API, a URI rewrite rule must be used:

# these rewrites are only if default RabbitMQ virtual host is used
location ~* /rabbitmq/api/(.*?)/(.*) {
    proxy_pass http://rabbitmq-host:15672/api/$1/%2F/$2?$query_string;
}

location ~* /rabbitmq/(.*) {
    rewrite ^/rabbitmq/(.*)$ /$1 break;
    proxy_pass http://rabbitmq-host:15672;
}

参考官方文档，Nginx代理配置如下：

location ~* /rabbitmq/(.*) {
        rewrite ^/rabbitmq/(.*)$ /$1 break;
        proxy_pass http://127.0.0.1:15672;
        proxy_set_header Host $http_host;
        proxy_set_header X-Real-IP $remote_addr;
        proxy_set_header REMOTE-HOST $remote_addr;
        proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for;
}
