Nginx服务器上的Unicorn + Rails拒绝连接

Question

我的应用程序返回502错误：

在error.log中：

2017/10/12 15:42:28 [错误] 12727＃12727：* 415 connect（）到Unix：/var/www/autonomos/production/current/tmp/sockets/unicorn.sock失败（111：连接被拒绝）在连接到上游时，客户端：172.31.81.4，服务器：api.autonomosapp.com.br，请求：“ GET / v1 / auth / validate_token HTTP / 1.1”，上游：“ http：// unix：/ var / www / autonomos / production / current / tmp / sockets / unicorn.sock：/ v1 / auth / validate_token “，主持人：” api.autonomosapp.com.br“

我启用了Nginx /网站

    break;

console owner

post-stop exec kill `cat /var/www/autonomos/production/current/tmp/pids/unicorn.pid`

respawn

unicorn.stderr.log

我的unicorn_autonomos_production不在init.d中，有问题吗？

当我尝试：

service unicorn_autonomos_production start

错误是：

无法启动unicorn_autonomos_production.service：找不到单元unicorn_autonomos_production.service。

我今天重新加载了Nginx服务器，我也需要初始化独角兽吗？ 我能怎么做？

Answer 1

我在终端上执行命令：

exec /usr/local/rvm/bin/autonomos_production_unicorn_rails -E production -c /var/www/autonomos/production/current/config/unicorn.rb -D > /tmp/upstart_autonomos_production.log 2>&1

和初始化独角兽
