新手问题 [Fixed] Mina 部署到 VPS 上后, Rails 无法启动

使用 Mina 部署到 到 VPS 上一直报错,Passenger/Nginx 一直报错。查看了 Nginx 的 error.log, 也直接在 current 文件夹中运行 bundle exex rails s -e production 同样的报错。

在 Google 上搜了下,也没知道合适的解决方案。

但是,如果我直接 登录到 VPS 通过 Github 将项目 clone 下来,运行 rails s -e production, 就一切 OK.

current $ bundle exec rails s -e production
=> Booting WEBrick
=> Rails 4.1.8 application starting in production on http://0.0.0.0:3000
=> Run `rails server -h` for more startup options
=> Notice: server is listening on all interfaces (0.0.0.0). Consider using 127.0.0.1 (--binding option)
=> Ctrl-C to shutdown server

把这三行从 :development 里面拿出来放到最外面试试看

#1 楼 @blacktulip 貌似 OK 了,我在 VPS 上直接 rails s -e production 没问题了,这是为什么呢? 现在切换到 Passenger/Nginx 后, 403 了。汗。。。。

#2 楼 @springwq

你仔细看错误信息, No such file to load -- pry (LoadError) 说明服务器上没有 pry ,为什么没有呢?因为你 gemfile 里面指明只有开发环境要装 pry ,服务器是生产环境自然不会装。

至于为什么 403 这个就不清楚了,好好查查 log

#4 楼 @blacktulip 终于搞定了, nginx.conf 里面路径没写对。Big Thanks!

#2 楼 @springwq 你的 vps 内存多大?
