在阿里云上部署 rails 时，总是出现：We're sorry, but something went wrong。

重装了五遍系统，谷歌尝试多次，但是仍然报错。

所以发帖请求大神们的帮助。非常感谢。

    server_name eyulaodu.com;

    # Tell Nginx and Passenger where your app's 'public' directory is
    root /var/www/myapp/code/public;

    # Turn on Passenger
    passenger_enabled on;
    passenger_ruby /usr/local/rvm/gems/ruby-2.3.1/wrappers/ruby;

先检测 passenger 是否正常工作

我隐约记得 passenger 好像和 nginx 搭配要重新编译一下

不嫌弃的话 试试 puma

Phusion Passenger 怎么安装的？

sudo /usr/sbin/passenger-memory-stats, 貌似正常的。

根据官方教程，安装的：

sudo apt-key adv --keyserver hkp://keyserver.ubuntu.com:80 --recv-keys 561F9B9CAC40B2F7

sudo apt-get install -y apt-transport-https ca-certificates

sudo sh -c 'echo deb https://oss-binaries.phusionpassenger.com/apt/passenger xenial main > /etc/apt/sources.list.d/passenger.list'

sudo apt-get update

sudo apt-get install -y nginx-extras passenger

tim_lang #5 June 06, 2017

看看环境变量有没有配置。

yingce #6 June 06, 2017

passenger 在 nginx 有一个运行环境设置 rails_env。你可以远程进一下 console 看看是什么环境运行的

nouse #7 June 06, 2017

查一下 /var/log/nginx/error.log，passenger 启动需要额外安装 passenger native support，阿里云上因为是只读的文件系统可能会出错

ringokun #8 June 06, 2017

跑sudo apt-get update的时候，有没有遇到这个问题：

E: Failed to fetch https://oss-binaries.phusionpassenger.com/apt/passenger/dists/xenial/main/binary-amd64/Packages Bad header line

墙的问题

chenge #10 June 07, 2017

config 有调试开关打开，可以看到具体的错误。或者看 log。
