即时尝试在heroku free environmnent上启动nginx服务器.我准备了任何方法和教程,但我没有让它运行.
首先,我想在端口80上启动nginx作为默认的Web服务器.之后我想配置nginx作为下划线express服务器(其他heroku实例)的代理.
4天我试图在我的heroku实例上只启动nginx.我总是得到不允许在端口80上启动的异常.
我从(https://github.com/benmurden/nginx-pagespeed-buildpack)分叉了nginx-buildback(https://github.com/moohkooh/nginx-buildpack)来调整一些配置.如果我通过端口2555上的heroku bash运行nginx,nginx正在启动,但我在Web浏览器上拒绝连接.
如果我通过Dyno启动nginx我在日志上收到错误消息
State changed from starting to crashed
我的Dyno的Procfile
web: bin/start-nginx
我的nginx.config.erb
daemon off;
#Heroku dynos have at least 4 cores.
worker_processes <%= ENV['NGINX_WORKERS'] || 4 %>;
events {
use epoll;
accept_mutex on;
worker_connections 1024;
}
http {
gzip on;
gzip_comp_level 2;
gzip_min_length 512;
server_tokens off;
log_format l2met 'measure#nginx.service=$request_time request_id=$http_x_request_id';
access_log logs/nginx/access.log l2met;
error_log logs/nginx/error.log;
include mime.types;
default_type application/octet-stream;
sendfile on;
server {
listen <%= ENV['PORT'] %>;
server_name _;
keepalive_timeout 5;
root /app/www;
index index.html;
location / {
autoindex on;
}
}
}
我还将PORT变量设置为80
heroku config:get PORT
80
其他一些配置:
heroku config:get NGINX_WORKERS
8
heroku buildpacks
https://github.com/heroku/heroku-buildpack-multi.git
heroku stack
cedar-14
我的.buildpack文件
https://github.com/moohkooh/nginx-buildpack
https://codon-buildpacks.s3.amazonaws.com/buildpacks/heroku/ruby.tgz
我也有猜测,heroku不使用我设置为80的变量.怎么回事?非常感谢任何人.
顺便说一句:我的快递服务器在端口1000上没有任何错误运行(对于测试我也在端口80上启动它而没有任何错误)
最佳答案 我用这个配置解决了我的问题.
daemon off;
#Heroku dynos have at least 4 cores.
worker_processes <%= ENV['NGINX_WORKERS'] || 4 %>;
pid nginx.pid;
events {
worker_connections 1024;
}
http {
gzip on;
gzip_comp_level 2;
gzip_min_length 512;
server_tokens off;
log_format l2met 'measure#nginx.service=$request_time request_id=$http_x_request_id';
access_log logs/nginx/access.log l2met;
error_log logs/nginx/error.log;
include mime.types;
server {

server_name localhost;
