Scrapy + Splash = Connection Refused

I installed Splash using this link. Followed all steps to installation, but Splash doesn't work.

My settings.py file:

BOT_NAME = 'Teste'
SPIDER_MODULES = ['Test.spiders']
NEWSPIDER_MODULE = 'Test.spiders'
DOWNLOADER_MIDDLEWARES = {
     'scrapy_splash.SplashCookiesMiddleware': 723,
     'scrapy_splash.SplashMiddleware': 725, 'scrapy.downloadermiddlewares.httpcompression.HttpCompressionMiddleware': 810,}
SPIDER_MIDDLEWARES = {
'scrapy_splash.SplashDeduplicateArgsMiddleware': 100,
}
SPLASH_URL = 'http://127.0.0.1:8050/'

When I run scrapy crawl TestSpider:

[scrapy.core.engine] INFO: Spider opened

Here is my spider:

import scrapy
from scrapy_splash import SplashRequest

class TesteSpider(scrapy.Spider):
    name="Teste"

    def start_requests(self):
            yield SplashRequest("http://www.google.com.br", self.parse, meta={"splash": {"endpoint":"render.html",}})

    def parse(self, response):
            self.log('Hello World')

I tried to run this in terminal: curl http://localhost:8050/render.html?url=http://www.google.com/"

Output:

curl: (7) Failed to connect to localhost port 8050: Connection Refused

You need run via command line:

sudo docker run -p 8050:8050 scrapinghub/splash

And settings.py as

SPLASH_URL = 'http://localhost:8050'

please make sure your splash server is up and running before calling the spider.

sudo docker run -p 5023:5023 -p 8050:8050 -p 8051:8051 scrapinghub/splash
